Our intercom system design guide is intended both for those who are familiar with intercom systems and for those who are just beginning to explore the subject and need a starting point to understand the basics. <\/p>\n\n\n\n<p>The guide contains the necessary knowledge to plan and design an intercom system. It includes advice on key information about facilities, production, users and the way of working that should be obtained to prepare the optimal solution to ensure the best communication. <\/p>\n\n\n\n<p>The list and variety of applications in which intercom systems play a decisive role is extremely extensive. We will try to describe the most common installations, because there is nothing more useful than concrete examples. Thanks to them we will clearly illustrate real solutions. On the website <a href=\"https:\/\/www.clearcom.com\/\" target=\"_blank\" rel=\"noreferrer noopener\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">Clear-Com<\/mark><\/a> there are dozens of installation templates for intercom systems, ranked by different applications.

This e-book is available for download as a file <a href=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/07\/Poradnik-projektowania-systemu-interkomowego___e_Book_-1.pdf\" target=\"_blank\" rel=\"noreferrer noopener\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">PDF<\/mark><\/a>.<\/p>\n\n\n\n<p>Intercom systems are used in a wide range of facilities with widely varying characteristics. From industrial, sports, healthcare and education to art centers, cinemas, theaters, concert halls or TV studios. However, they all follow a common design methodology based on very simple criteria, which we will describe later in this guide. The design of an intercom system, like the design of any key system, must begin by defining individual user requirements. This definition must include operational, environmental and budgetary considerations. The most critical of these are operational i.e. answering the question <strong>\u201eWhat does the user need?\u201d<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>In all cases, a full understanding of the user's communication needs is the basis for designing a properly functioning intercom system.<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>We have divided our guide into four parts.<br>In part one , we will review the most common communication techniques used in most modern intercom systems. This information will come in handy when developing the users' workflow and the layout of their workstations.<\/p>\n\n\n\n<p>Chapter two, describes the series of products from which you can build an intercom system. This section contains important information on IP protocol standards and norms that may require additional reading. We have included a list of additional material at the end of the chapter. From this section, you will learn how the various products perform their functions described in the first section and how to use this knowledge during the design described in the next section.<\/p>\n\n\n\n<p>In part three, we will outline the steps you need to take to define the users of the system and how they work at a given site. In some cases, it is useful to reverse the order - to define the workplace and the people. We cover both examples.<\/p>\n\n\n\n<p>At this point, it is worth emphasizing how much understanding how users work contributes to correctly defining the needs that a well-designed intercom system should provide. We all know very well that proper workflow is essential for success in any industry. In the framework of an organized production, event or even meeting, we follow a scenario or agenda, and each participant applies a specific workflow to bring his task to its goal. Remember to always take into account how users interact. For example, we may notice that the spot operators in the show receive instructions from the light director, so we can plan that there is a need for a communication channel between them. We also know that spot operators may need to communicate among themselves, called a private channel. Understanding the communication needs and the work system will certainly help build a solid intercom system design.<\/p>\n\n\n\n<p>In the fourth chapter, we present some sample projects based on user data, following the process described in the previous chapters.<\/p>\n\n\n\n<p><strong>Foreword<\/strong><\/p>\n\n\n\n<p>Leaving aside the issues of audio formats and transmission platforms, there are several types of intercom systems and their subsystems, including: wired analog, networked (digital) partyline systems, wireless partyline systems, matrix systems, interfaces, systems based on virtual communication, and communication subsystems such as IFBs. As you may have experienced, in most final facilities, intercom communication is based on a combination of the various aforementioned options, so the total number of possible solutions is very large.<\/p>\n\n\n\n<p>The challenge in understanding intercom functionality and operational capabilities is the confusing use of identical terms that have different meanings in different contexts. To simplify this guide, we will focus on the two most commonly used communication protocols. One is a direct connection between two people called \u201e<strong>point-to-point<\/strong>\u201d or communication between a group of people is often referred to as \u201e<strong>partyline<\/strong>\u201e. In some applications or in certain countries <strong>partyline<\/strong> is called a \u201econference\u201d term.<\/p>\n\n\n\n<p>Other forms of intercom communication worth considering after the basic design is done include:<\/p>\n\n\n\n<p>(a) Group Calls - Group Calls (sometimes referred to as one-to-many) involve a set of devices, such as interfaces, panels and partylines, that can be treated as a single element. A user who has a preset button assigned to a fixed group can simultaneously talk to anyone who is part of that fixed group. A fixed group differs from a partyline in that group membership is determined by the configuration of the intercom system (it is not edited dynamically). For example, a group call could be an \u201eall\u201d call from the director to get the attention of everyone involved in the production.<\/p>\n\n\n\n<p>(b) ISO (isolated) calls - allow a user of a line (partline) to isolate himself from that line for a private conversation. An example for an ISO call would be when a video engineer wants to use a conversation with a camera operator isolated from the partline.<\/p>\n\n\n\n<p>(c) Unidirectional communication called IFB (interruptible foldback) for transmitting directions, messages or prompts to, for example, TV presenters. An IFB-type signal can also be routed to a speaker (e.g., in a dressing room) or headphone. A typical example is an audio track with background music that can be interrupted by an announcement.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\" id=\"sekcja-1-popularne-techniki-komunikacji\">SECTION 1.<br>POPULAR COMMUNICATION TECHNIQUES<\/h2>\n\n\n\n<p class=\"has-text-align-center\">The most popular method of intercom communication is by far the Partyline format.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"1-1-partyline\">1.1 Partyline<\/h3>\n\n\n\n<p>The term \u201epartyline\u201d can refer to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Wired 2wire (two-wire, two-wire) intercom system developed by Clear-Com<\/li>\n\n\n\n<li>Wireless intercom system<\/li>\n\n\n\n<li>Conference (conference) in the 2wire system<\/li>\n\n\n\n<li>Conference (conference) in a matrix intercom system<\/li>\n<\/ul>\n\n\n\n<p>Technically, a partyline intercom (also referred to as a \u201etalkback\u201d or two-wire system in some parts of the world) is a communication system in which the communication channel is shared for both speaking (TALK) and listening (LISTEN). An analog partyline intercom circuit transmits and receives audio on two wires. Digital and\/or networked partyline intercoms work the same way, the difference is that they are based on Ethernet.<\/p>\n\n\n\n<p> A partyline is by nature a \u201econference.\u201d The name \u201epartyline\u201d (PL) comes from telephone systems in which more than one subscriber shared the same line and could hear and join all conversations simultaneously. Therefore, partyline intercoms, despite the format, are fully duplex (you can listen and talk at the same time) and are not private. As a group communication tool, partyline allows a group of people with similar tasks to communicate continuously. For example, one person can talk while everyone else on the bus or channel can listen. Most users only talk on one or two channels, receiving directions and talking within their own group. Keep all of this in mind for partyline, because as a design criterion later in this book, you may ask yourself, how do the people in my facility function and is it best for them to communicate as a task-specific group?<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>In the audio industry, the name \u201eChannel\u201d can also be used to describe a wireless beltpack, audio track in an audio console, two-way radio or wireless microphone.<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p> \u201ePL\u201d is an abbreviation for \u201epartyline,\u201d but in common parlance it can refer to an intercom system, a user station in an intercom system, and all kinds of communications conferences (including teleconferencing). In the case of partyline systems, the TALK and LISTEN channel is almost always related and defined by the term \u201echannel\u201d (CHANNEL). <\/p>\n\n\n\n<p>Consider a standard production where we have a FOH realizer, a MON realizer, several technicians and a person responsible for all the wireless microphones. This is a good example of a group of people who share a common worfklow, i.e. audio. A proper intercom design would include providing a partyline channel for these users, and this partyline has been designated and named the audio \u201echannel.\u201d (Note that other users need or may need access to any or all of the audio staff - as an advanced design requirement, we will discuss this in the design section).<\/p>\n\n\n\n<p>Figure 1 shows an example of a classic partyline system<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"453\" src=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-1.2-1024x453.jpg\" alt=\"\" class=\"wp-image-5908\" srcset=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-1.2-980x433.jpg 980w, https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-1.2-480x212.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><figcaption class=\"wp-element-caption\">Figure 1: Clear-Com 4 channel concept using a single shielded twisted pair cable<\/figcaption><\/figure>\n\n\n\n<p>A classic \u201eanalog\u201d partyline intercom system will always include a simple power supply or powered main intercom station used to distribute current and signal to the intercom line circuits. This means that a DC voltage is added to the signal line to power the user station. This simple system in Figure 1 contains four partyline \u201echannels\u201d in the main station\/PSU, which we see labeled A\/B\/C\/D. In a real-world application, these \u201echannels\u201d could be assigned to a group of users , e.g., channel B in Figure 1 could depict a group of audio personnel in a facility. Note that the four powered channels are distributed throughout the facility, and the end-user stations connect the appropriate channel circuit as required. With digital or networked partyline systems, all channels created are available on a single wire, and configurations determine which channels are available at each endpoint. This flexibility allows the user to choose the channels on which they talk and listen. More on this is explained below, moving on to the choice between analog and digital systems and infrastructure decisions. Conference workflows are not limited to standalone analog or networked partyline systems, but can also be configured workflows in a more efficient digital matrix intercom platform and added to user stations as required. As a reference to be discussed later, for partyline\/conferencing support, we need to know how many simultaneous calls must be supported. This will allow us to determine the number of channels required for analog or digital partyline systems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"1-2-point-to-point-pt-p\">1.2 Point-to-Point (PtP).<\/h3>\n\n\n\n<p>Point-to-Point (PtP) workflow enables one-to-one communication. In production intercoms, PtP is direct communication between two intercom stations or between stations and interfaces. It is the basis of communication in matrix intercom systems. The conversation is limited to individuals selected by the call originator, ensuring complete privacy between stations. This call usually includes a \u201etally\u201d (call light) subsystem to also visually call out the caller's destination. Most calls are full-duplex. A typical example is a point-to-point setup between a producer and a program director. <strong>Attention: <\/strong>For large multi-channel partyline systems, it is quite common that a partyline channel can be used as a personal partyline (PPL) between two users for simulated PtP communication. <\/p>\n\n\n\n<p>As mentioned earlier, most intercoms are simple wired partyline systems with the addition of wireless partyline intercom. This is based on several design criteria, such as the technical ability of the user to use the intercom station and\/or the frequency with which the intercom can be used, compared to the cost of wiring the facility.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"1-3-bezprzewodowy-system-interkomowy\">1.3 Wireless intercom system<\/h3>\n\n\n\n<p>In most applications, a wireless intercom is an extension of a wired system, used by those employees who require mobility for safety or convenience. Wireless intercoms are typically used for group\/partyline communications, as described in the analog partyline section above. They rarely occur as point-to-point communications; however, wireless systems are available that have this capability and are described in detail later in this guide. <\/p>\n\n\n\n<p>Systems typically consist of a \u201ebase station\u201d and a limited number of wireless beltpack\/handset stations that can interact with the base station and are \u201epaired\u201d with it. Wireless intercom communication is in full-duplex mode; however, some systems offer various operational modes in which they can be used in half-duplex mode, allowing more wireless users to use the system.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"551\" src=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-2-1024x551.jpg\" alt=\"\" class=\"wp-image-5907\" srcset=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-2-980x527.jpg 980w, https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-2-480x258.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"1-4-uwagi-dotyczace-planowania-wstepnego\">1.4 Notes on pre-planning<\/h3>\n\n\n\n<p>A typical wired or wireless production intercom system will always consist of <strong>Users<\/strong>, sometimes <strong>IFB Circuits<\/strong>, sometimes <strong>Kamer<\/strong> and mostly different ports (including two-way radios, analog and digital phones, <strong>Invocations<\/strong>, other intercom interfaces, etc.) The first step is to determine the size of the central intercom by counting everything connected to it.<\/p>\n\n\n\n<p><strong>Users<\/strong><\/p>\n\n\n\n<p>Intercom users are operators with panels, speaker stations, wired and wireless beltpacks or software clients on PCs, cell phones and tablets.<\/p>\n\n\n\n<p><strong>IFB Circuits<\/strong><\/p>\n\n\n\n<p>JIf the production requires the use of IFB circuits, you need to plan for the number of users using the prompts, i.e. as described above in the sidebar. Sometimes prompts can be more general than individual prompts, and therefore can be treated as paging. See \u201epaging\u201d below. In partyline systems, the need for IFB circuits is often handled through a separate subsystem.<\/p>\n\n\n\n<p><strong>Cameras<\/strong><\/p>\n\n\n\n<p>If there are cameras in the facility, the easiest and simplest solution is to count the number of cameras as individual circuits. It is not recommended to daisy-chain camera circuits or bridge them without a proper mixer. Camera circuits can be combined in the intercom into a partyline channel if necessary. The best way to connect a camera intercom to the system is to access the camera CCU intercom circuit as a four-wire (4-wire) circuit. A 4-wire connection is often not available on less expensive cameras. For such projects, we recommend routing the microphone cable along with the camera cable and connecting the beltpack at the end, or considering a wireless system.<\/p>\n\n\n\n<p><strong>Recalling (Paging)<\/strong><\/p>\n\n\n\n<p>Paging is a one-way or simplex communication circuit from a source (or initiator) to a destination. Examples of paging destinations include Stage- Studio- Announce, dressing rooms, backstage, backrooms. <\/p>\n\n\n\n<p><strong>Classic and timeless<\/strong><\/p>\n\n\n\n<p>Should you completely replace your existing intercom system? Possibly not! Clear-Com's products have been on the market for more than 50 years, and some of our systems have been in continuous operation for just as long. The good news is that the latest analog two-wire partyline products are fully compatible with older partyline equipment. In fact, all Clear-Com products, whether analog, digital or IP-based, can be combined with older analog solutions. It is a good idea to start the expansion of an existing system with a general review and refresh of the cable installation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\" id=\"sekcja-2-wybor-typow-urzadzen\">SECTION 2<br>SELECTION OF DEVICE TYPES<\/h2>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"2-1-przeglad\">2.1 Overview<\/h3>\n\n\n\n<p>Currently available analog 2-wire partyline systems offer high performance, low to moderate cost, and can use single or multiple channels. Their greatest advantages are simple wiring, easy expansion with additional stations, very few central units required, and uncomplicated operation.<\/p>\n\n\n\n<p>The disadvantages of such solutions include their dependence on hybrids, or 2-wire to 4-wire converters (these are required to interconnect systems and cause significant performance degradation), the difficulties encountered when interconnecting them with other 2-wire systems with different characteristics, the inability to selectively call multiple stations, and limited call privacy. For situations where intercom locations change frequently, a major disadvantage of analog partyline intercoms is that changes in channel distribution and routing require rewiring.<\/p>\n\n\n\n<p>Digital systems offer greater efficiency. They can use single or multiple channels and allow routing configurations between users.  Unfortunately, this comes at a much higher cost. The biggest advantage of digital partyline systems is simple wiring.  Compared to analog systems, which are wired separately for each line, in digital systems all channels are run over a single wire. These systems are based on Ethernet, so they take advantage of the flexibility offered by IP networking capabilities.<\/p>\n\n\n\n<p>Matrix systems are the most advanced intercom solutions offering a whole range of new capabilities and advantages.<\/p>\n\n\n\n<p> These include size, configurability, variety of supported communication types and available features not available in previously discussed devices. The most simplistic matrix intercom system (4-wire) transmits audio on one pair of wires and receives on the other. This format is point-to-point in nature and can be visualized as a star configuration - each station connects to the center via its own multi-wire link. Today, these are IP-based links, which, while adding complexity characteristic of Ethernet, remain the same in terms of features, functions and usability. At the heart of the matrix solution is a central processor and software that allows the system to be dynamically configured, opening up enormous communication possibilities for all its users.<\/p>\n\n\n\n<p>Since all stations can connect with each other, the system is managed by dedicated software. Changing who talks to whom, rules about what happens under certain circumstances, and assigning functions to buttons on devices are all under the control of the system software.&nbsp;<\/p>\n\n\n\n<p>The disadvantages of matrix systems mainly lie in the fact that they can require a significant investment in central units and their expansion can be costly.<\/p>\n\n\n\n<p>Whether you're using 2-wire, wireless or matrix-based intercoms, the latest developments combine these platforms into a single system, a self-contained, functional IP central station.

In its basic configuration, the HelixNet system supports powerline technology, in which Ethernet packets are modulated to the powerline. This allows several connected stations to share the same physical medium.<\/p>\n\n\n\n<p>Ethernet-based devices such as beltpacks, speaker stations and remote master stations can be connected to a powered \u201epowerline\u201d output. This is done using standard shielded, 3-pin XLR (microphone cable) cables.  The same topologies as in analog partyline systems are used, including passive splitters - daisy chain. The most important attribute of the HelixNet platform is that it is familiar to existing users of Clear-Com's analog partline systems, while offering impressive flexibility through an architecture based on very extensive configuration capabilities.<\/p>\n\n\n\n<p>Unlike analog partyline systems, where the required number of channels must be connected to a dedicated power source, the number of partyline channels is virtual and created at the HelixNet master station. The system creates 12 partyline channels with the ability to increase to 24 by purchasing an additional license, and all channels use a single cable.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1503\" height=\"939\" src=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial_audio_large-HelixNet_Group-1_Original-3-edited.jpg\" alt=\"\" class=\"wp-image-5953\" style=\"width:822px;height:464px\" srcset=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial_audio_large-HelixNet_Group-1_Original-3-edited.jpg 1503w, https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial_audio_large-HelixNet_Group-1_Original-3-edited-1280x800.jpg 1280w, https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial_audio_large-HelixNet_Group-1_Original-3-edited-980x612.jpg 980w, https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial_audio_large-HelixNet_Group-1_Original-3-edited-480x300.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 1503px, 100vw\" \/><\/figure>\n\n\n\n<p>HelixNet allows two basic ways to connect components.

These platforms are referred to as fully summing audio matrices, where a central element such as a matrix performs this functional task. This means that any input or number of inputs can be routed to any output or any number of outputs with full control and adjustment of the crosspoint level. The term crosspoint refers to a unidirectional audio path from the input of one port to the output of another. Crosspoints exist between each pair of ports in the system and are connected and disconnected as needed to provide communication paths between the system ports on the TDM backplane. A distinguishing feature is the ability to adjust the level of the crosspoints, which is not typical of traditional audio routers. Clearly, when multiple people are talking, the ability to adjust listening levels is critical for the system to function properly and maintain proper communication. Configuration software is used to create and manage communication paths between devices, including matrices, interface cards, interface modules and panels.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/03\/commercial_audio_large-Eclipse-HX-Omega-Front-1024x576.jpg\" alt=\"\" class=\"wp-image-5532\" srcset=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/03\/commercial_audio_large-Eclipse-HX-Omega-Front-980x551.jpg 980w, https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/03\/commercial_audio_large-Eclipse-HX-Omega-Front-480x270.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><\/figure>\n\n\n\n<p>The basic hardware components of Eclipse HX Matrix intercom systems are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Matrix card frame<\/li>\n<\/ul>\n\n\n\n<p>The heart of any intercom built on a matrix must have a Central Processing Unit (CPU). The CPU stores complete system configurations in its memory. Each matrix system contains at least one CPU. Most matrices are shipped with two CPU cards (in primary and secondary relationship) to ensure fail-safe operation.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Various I\/O cards sometimes called \u201cclient cards\u201d<\/li>\n<\/ul>\n\n\n\n<p>There are a variety of cards available for matrix systems. These are I\/O cards that create interface connections to intercom stations, sources and destinations. They also allow conversion between different audio formats. The cards are described as \u201eports.\u201d Ports refer to the number of connections available to external devices to and from the matrix, although in the case of IP-based cards the ports are virtual. Typically, a port is assigned a function within the configuration software. This function determines what type of device is connected to the port, such as a user panel, interface, or 4-wire device. The software is used to set the function parameters for the port.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Rear panel connectors.<\/li>\n<\/ul>\n\n\n\n<p>The matrix connects to remote devices such as panels, interfaces, general purpose inputs and outputs, local area networks (LANs) and other matrices via connectors on the rear panel. RJ45 connectors are found on analog 4-wire, IP and Ethernet network cards, while digital connections may include BNC or fiber or both for MADI I\/O. Typical D-sub connectors are used for external functions such as GPIO.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Interface modules<\/li>\n<\/ul>\n\n\n\n<p>Because the intercom is considered a mission-critical telecommunications device, each matrix frame operates with two independent power supplies. To ensure redundancy, they must be connected to a main and backup power supply. If one of these power supplies fails, the other automatically takes over.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Panels&nbsp;<\/li>\n\n\n\n<li>An external computer (PC) running the configuration software<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"613\" src=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-3-1024x613.jpg\" alt=\"\" class=\"wp-image-5909\" srcset=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-3-980x587.jpg 980w, https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-3-480x287.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><figcaption class=\"wp-element-caption\">This figure shows the various connectivity options available on the Eclipse matrix system.<\/figcaption><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><strong>Matrix Trunk Systems<\/strong><\/p>\n\n\n\n<p>We use trunking methodologies for system expansion and the need to connect multiple matrix intercoms.

Users can choose among available wireless beltpacks with two, four or as many as eight channels of party-line and point-to-point communication. Wireless intercom communication is in full-duplex mode.<\/p>\n\n\n\n<p>Advantages of wireless intercom systems include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Greater freedom of movement for the user<\/li>\n\n\n\n<li>Simple installation, avoiding wiring problems typical of wired intercoms.<\/li>\n\n\n\n<li>Reduction of tripping hazards associated with cables in the utility space<\/li>\n<\/ul>\n\n\n\n<p><strong>Wireless technology<\/strong><\/p>\n\n\n\n<p>Clear-Com offers nine different wireless intercom solutions. These range from a basic 2.4 GHz-based radio system that does not connect to any other external intercoms or sources, to sophisticated FreeSpeak systems.&nbsp;<\/p>\n\n\n\n<p>The frequencies used in Clear-Com's wireless solutions include 1.9 GHz DECT, 2.4 GHz and 5 GHz radio technologies.<\/p>\n\n\n\n<p>The most popular solution is the FreeSpeak II 1.9 GHz system, which is based on dedicated, distributed wired transceivers. From an RF installation standpoint, the FreeSpeak system can be considered a plug-and-play system. There is no need for frequency coordination, and the installer simply needs to place the transceivers in predetermined coverage zones and using the appropriate instructions described in the manual. For systems using a single transceiver per base station, each transceiver should be separated from the transceivers of every other system for best collocation performance.&nbsp;<\/p>\n\n\n\n<p>Clear-Com FreeSpeak base station systems include a browser-based configuration tool called Core Configuration Manager (CCM). CCM facilitates a quick and easy way to configure wireless beltpack devices, including role-based endpoint configuration, account management, save and restore, and live monitoring of all system components.<\/p>\n\n\n\n<p><strong>Placement of the transceiver<\/strong><\/p>\n\n\n\n<p>One of the most important factors in an RF system is the placement of the transceiver so as to provide optimal coverage over the desired area. Digital wireless intercoms (2.4 GHz, 1.9 GHz DECT systems and 5 GHz) use a dual transceiver diversity system. It is extremely important that transceivers are connected and properly positioned at all times for best RF performance. Unlike older analog VHF and UHF intercom systems, which had dedicated transmit and receive antennas, each digital transceiver is both a transmitter and a receiver.<\/p>\n\n\n\n<p><strong>Some important points to keep in mind when placing DECT transceivers are:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Each transceiver has a coverage pattern. The 1.9 GHz DECT system transceiver patterns must overlap in the desired area to ensure the best RF performance.<\/strong><\/li>\n\n\n\n<li><strong>In many cases, the best place to place the transmitters, is a point well above the desired coverage area (at least above head level) and point the transmitters directly down into the coverage area.<\/strong><\/li>\n\n\n\n<li><strong>Maintaining a direct line from the antenna to the beltpack is the best possible scenario for the best signal strength.<\/strong><\/li>\n\n\n\n<li><strong>Always keep transceivers away from the<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Large metal objects; keep a distance of at least 60cm. <\/strong><\/li>\n\n\n\n<li><strong>Large containers of liquids. Most liquids absorb the RF signal.<\/strong><\/li>\n\n\n\n<li><strong>Enclosed spaces. Do not place receivers in rooms or enclosed areas with very few RF points.<\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p><strong>Interface for wireless partyline systems<\/strong><\/p>\n\n\n\n<p><strong>2W\/4W interfaces<\/strong>.&nbsp;<\/p>\n\n\n\n<p>Wireless standalone intercom systems (not matrix-based) are equipped with two-wire (three-pin XLRM&amp;F) interfaces to analog wired partyline systems and analog 4-wire I\/O (typically RJ45) for connection to digital wired partyline devices, matrix intercoms and third-party audio devices. The 2-wire interfaces have options to connect to both RTS TW and Clear-Com systems. Audio send and receive trimmers are built in for both 2-Wire and 4-Wire I\/O. All base stations feature nulling when connecting an analog 2-wire circuit.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"2-4-wybor-typow-urzadzen-sieci-interkomowe-i-ip\">2.4 Selection of device types - intercom and IP networks<\/h3>\n\n\n\n<p>Communication over IP network<\/p>\n\n\n\n<p>The days when real-time audio and IT networks were incompatible are certainly over. The attractiveness of IT networks as an audio medium has never been more obvious: low connection cost, very high capacity, flexibility and global infrastructure.<\/p>\n\n\n\n<p>Transmitting high-quality intercom signals over such networks is not without its challenges. IT initially did not support real-time audio synchronization and typically used retransmission to compensate for this problem - a technique completely inappropriate for voice communications. However, higher-bandwidth connections,clocking protocols and advanced VPN management tools allow standard networks to meet the challenge of intercom routing locally and globally.<\/p>\n\n\n\n<p>For IP-based digital intercom systems, there are typically four scenarios that benefit from IP-based communications:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Key-panel operator-to-host matrix\/main station (including soft clients)<\/li>\n\n\n\n<li>Matrix-to-matrix or intelligent central station linking<\/li>\n\n\n\n<li>\u201eGlue\u201d systems that connect traditional systems through IP infrastructure (LQ) - Matrix\/Glue Systems-to-digital telephony gateways<\/li>\n<\/ul>\n\n\n\n<p>Central to the use of off-the-shelf IT components is compliance with the set of standards that together define an IP network. This includes protocols such as RTP, IGMP, QoS and PTP, all of which are used in audio and video streaming over IP, but are unfamiliar to IT professionals outside the broadcast industry.&nbsp;<\/p>\n\n\n\n<p>In addition, it should be noted that production intercom, especially in the Broadcast and AV media market segments, is moving to a new way of working, from dedicated point-to-point cable connections between devices, to the use of Audio over IP (AoIP) networks using AES67 digital audio or the SMPTE ST2110-30 standard.<\/p>\n\n\n\n<p>Consequently, the success of the installation and project depends on a properly configured IP network infrastructure. There are a number of practical steps that can be taken during the planning and installation phases to ensure that the configuration goes smoothly.<\/p>\n\n\n\n<p>Recommendations<\/p>\n\n\n\n<p>We recommend that a network engineer be present at each installation to help properly configure the devices.<\/p>\n\n\n\n<p>AES67 AoIP IP<\/p>\n\n\n\n<p>What is AES67?<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>This is the interoperability standard for High-performance Streaming Audio-over-IP.<\/li>\n\n\n\n<li>Used for audio transmission only<\/li>\n\n\n\n<li>It is not a complete system. AES67 is a function or option in an audio system that can perform other tasks such as routing, monitoring, sensing or system control.<\/li>\n<\/ul>\n\n\n\n<p>AES67 uses the IEEE 1588 Precision Time Protocol standard for synchronization.<\/p>\n\n\n\n<p>AES67 data packets are IP packets formatted according to the Real-time Transport Protocol (RTP). RTP standards define packet formats for many types of audio and video.<\/p>\n\n\n\n<p>AES67 runs on standard Layer 3 Ethernet networks and as such is routable and fully scalable.<\/p>\n\n\n\n<p>AES67 has no specific requirements for detection and control functions.&nbsp;<\/p>\n\n\n\n<p>Different products can use the sensing and control solutions of their choice.<\/p>\n\n\n\n<p>Interoperability without discovery and control is provided through the SIP protocol for call management and the designation of the SIP URI or SDP description as the information that must be disseminated by the discovery system. The standard use of several discovery systems, including Bonjour and SAP, is discussed informatively in the standard.<\/p>\n\n\n\n<p>Clear-Com devices that support AES67 use their own unique method of common detection.<\/p>\n\n\n\n<p>Which Clear-Com devices transmit AoIP AES67?&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Eclipse HX Matrix E-IPA-HX interface card&nbsp;<\/li>\n\n\n\n<li>Eclipse HX Matrix V-Series Iris Panel<\/li>\n\n\n\n<li>Clear-Com IP wireless transceivers (IPTs):\n<ul class=\"wp-block-list\">\n<li>FreeSpeak II: FSII-TCVR-IP-19 (1.9GHz)<\/li>\n\n\n\n<li>FreeSpeak Edge: FSE-TCVR-5-IP (5GHz)<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p>IP SMPTE ST2110-30<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>What is SMPTE ST2110-30?&nbsp;<\/strong><br><strong style=\"font-size: revert; font-family: inherit;\">S standard (ST-2110) specifies Real- time Transport Protocol, (RTP-based), synchronization and participation of separate video, audio, data streams over IP networks.

If you have read all of the previous material in its entirety, congratulations! But you may be slightly overwhelmed by the amount of information presented if you don't often design intercom systems. Assimilating such an amount of knowledge can be difficult, especially if intercom issues are new to you.<\/p>\n\n\n\n<p>The subject of intercom systems is often misunderstood. Partyline communication is the simplest form of this important element used in live events or simple television productions. Digital intercom systems have become increasingly powerful, flexible and complex. This is especially true for matrix and wireless intercoms. The size and features of modern installations allow for a greater number of users, and high-quality communication between them can take place from disparate and remote locations. The end result is worth the extra effort, as it allows for the creation of increasingly complex television, virtual, theatrical productions and corporate events. The implementation of IP technology has brought many new solutions that can create a local or global intercom network.<\/p>\n\n\n\n<p>It's time to move into the design process, starting with understanding user needs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\" id=\"sekcja-3-definiowanie-potrzeb-uzytkownika\">SECTION 3<br>DEFINING USER NEEDS<\/h2>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"3-1-szczegoly-dotyczace-uzytkownika\">3.1 User details<\/h3>\n\n\n\n<p>Questions to ask:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What is the use and type of facility?

It is critical to understand digital intercom technology and RF distribution including the placement and number of antennas.<\/p>\n\n\n\n<p>Here are some questions that will be helpful as you gather information about your project. When deciding what kind of wireless intercom to choose, the key is to know how to match features and functionality to a particular way of working.<\/p>\n\n\n\n<p>Questions to ask:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Will the wireless intercom be a stand-alone system or work together with a wired system and what type?&nbsp;\n<ul class=\"wp-block-list\">\n<li>When combining a wireless intercom with a wired intercom, it is important to consider the number of common channels between them. A simple example would be mobile (wireless) users who need to stay in communication with an audio group built on fixed wired intercom stations. Then count this as one common channel.<\/li>\n\n\n\n<li>Wireless stations most often offer a range of methods for connecting to other intercom and audio devices. However, the number of interface connections can be limited and is worth considering.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>How many channels may be needed in a wireless beltpack? Wireless beltpack stations offer 1, 2, 4 or 8 sets of keys that can refer to partyline channels or to a direct point-to-point connection.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>How many wireless beltpacks will be supported by the user, will the system need to be expanded in the future?<\/li>\n\n\n\n<li>How many people using wireless devices, need the ability to talk at the same time? We need to know, the maximum number of people talking at the same time on all audio channels.<\/li>\n\n\n\n<li>Where will the wireless intercom system be used? Take into account, cities, describe the facility and coverage objectives in that space. This is very important for selecting the appropriate operating frequency.<\/li>\n\n\n\n<li>Characterize the area that needs wireless intercom coverage - e.g., broadcast studio, temple, school auditorium, back of the building.<\/li>\n\n\n\n<li>What other wireless devices are used in the same area and on what frequencies do they operate?<\/li>\n\n\n\n<li>What type of headsets are required for the system? (Light, medium, single-membrane, dual-membrane, low-profile, etc.).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"3-4-szczegoly-dotyczace-ifb\">3.4 IFB details<\/h3>\n\n\n\n<p>IFB, or \u201eInterruptible Foldback,\u201d is a solution commonly used in television, although easy to overlook. It is one of the most important features within broadcast and some live events. IFB is a type of simplex intercom, used to send a program signal and intermittent sound (cue) on \u201eIFB\u201d lines to presenters or hosts. An IFB line consists of three components: <strong>Audio Program<\/strong>, <strong>Interrupt (Cue) Audio<\/strong> and control <strong>Dip<\/strong> or <strong>Mute<\/strong>.<\/p>\n\n\n\n<p>The IFB is used by a producer or director to give the presenter or host of a program directions, important information or calls during the show. Although IFB is most commonly used in the broadcast world, it can be used in a variety of situations requiring this type of communication, i.e., dressing rooms, temples (calls to prayer) or offices.&nbsp;<\/p>\n\n\n\n<p>People in management positions (e.g., director, producer or assistant director) control the interruption and announcement functions through control stations. People in receiving positions (on-air presenters, set managers, studio or field crew, audiences, presenters and teams in remote locations) are at the end of the line. They receive messages via headphones or speakers, and receiving devices can be wireless receivers, smartphones or tablets.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"587\" src=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-6-1024x587.jpg\" alt=\"\" class=\"wp-image-5916\" srcset=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-6-980x562.jpg 980w, https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-6-480x275.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><figcaption class=\"wp-element-caption\">Figure 2: Illustration of the control position for the IFB.<\/figcaption><\/figure>\n\n\n\n<p>This particular type of communication is sometimes overlooked in the design for various reasons. Consideration of all IFB circuits will not only ensure that the intercom is correctly sized, but will also help you understand the topology of the infrastructure, fit ancillary equipment such as any other interfaces to remote locations and panels.<\/p>\n\n\n\n<p>Supporting questions for the IFB:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>How many presenters or hosts will there be?<\/li>\n\n\n\n<li>How many operators must have access to the IFB system?<\/li>\n\n\n\n<li>How many software inputs are required and in what audio formats?<\/li>\n\n\n\n<li>Audio controls - dip or mute - will different users require different controls and will they be changed often or not?<\/li>\n\n\n\n<li>Are any of the outputs broadcast via radio or satellite?<\/li>\n\n\n\n<li>Will any of the outputs be connected via phone lines or other types of IP lines? If telephone lines and IP circuits will be in use this will require appropriate interfaces.<\/li>\n\n\n\n<li>How does the presenter\/leader talk to the IFB control operator? This is often done through the presenter\/leader's microphone.<\/li>\n\n\n\n<li>Will there be an increase in the number of positions for presenters or control operators in the future?<\/li>\n\n\n\n<li>What types of headphones or headsets do presenters require? In-ear headphones are the most common, but headsets with microphones are often used during broadcasts or sporting events.<\/li>\n<\/ul>\n\n\n\n<p>Once you have an established work organization, choosing equipment is much easier.<\/p>\n\n\n\n<p>As a supplement to this section, read the blog post \u201c<a href=\"https:\/\/www.google.com\/url?q=https:\/\/www.clearcom.com\/interruptible-fold-back-aka-ifb\/&amp;sa=D&amp;source=docs&amp;ust=1683888278554187&amp;usg=AOvVaw15dvKNkgEfGU8I3W91J_ui\" target=\"_blank\" rel=\"noreferrer noopener\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">Interruptible Fold Back, AKA IFB<\/mark><\/a>\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\" id=\"sekcja-4-przyklady-projektowe\">SECTION 4<br>DESIGN EXAMPLES<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"968\" height=\"1024\" src=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-7-968x1024.jpg\" alt=\"\" class=\"wp-image-5917\"\/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"4-1-teatr-korzystajacy-z-cyfrowych-przewodowych-i-bezprzewodowych-polaczen-partyline-oraz-infrastruktury-sieciowej-lan\">4.1 <strong>Theater using digital, wired and wireless Partyline connections and LAN network infrastructure<\/strong><\/h3>\n\n\n\n<p>Live productions in churches and theaters that include elements of broadcast, t.v. or streaming require well-designed communication capabilities - especially with handlers staying on the move and multiple mobile cameras.

The wired HelixNet PL endpoints are distributed within the network.<\/p>\n\n\n\n<p>In the configuration file, you can create channels for the teams you need, such as audio\/video\/cameras\/lighting\/stage management.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"664\" src=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-8-1024x664.jpg\" alt=\"\" class=\"wp-image-5918\" srcset=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-8-980x636.jpg 980w, https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-8-480x311.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"4-2-rozbudowa-analogowej-do-cyfrowej-linii-partyline-za-pomoca-serii-lq\">4.2 Extension of analog to digital partline with LQ series<\/h3>\n\n\n\n<p>Many facilities continue to successfully operate analog Partyline systems, which can be repurposed when upgrading with new wireless and networking solutions. The arrival of Version 4 for the LQ Series can breathe new life into existing analog systems.<\/p>\n\n\n\n<p><strong>How does it work?<\/strong><\/p>\n\n\n\n<p>Analog partyline systems, such as Encore, can connect directly to an LQ or LQ-R device and then via IP network to HelixNet or FreeSpeak II. In this example, the Arcadia central unit supports a wireless network and is connected to a wired digital HelixNet partyline using LQ-series devices. The HelixNet master station, Arcadia central station and LQ are on the LAN, sharing their physical inputs and outputs.<\/p>\n\n\n\n<p><strong>Application notes<\/strong><\/p>\n\n\n\n<p>LQ modules in this case connect as \u201elink members\u201d to HelixNet acting as host. LQ interfaces linking analog partline systems to 2-wire existing systems share their resources among all LQ units in the network, including LQs connected to Arcadia station along with 4-wire connectors.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"899\" src=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-9-1024x899.jpg\" alt=\"\" class=\"wp-image-5919\" srcset=\"https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-9-980x860.jpg 980w, https:\/\/commercialaudio.pl\/wp-content\/uploads\/2023\/05\/commercial-audio-poradnik-projektowania-systemu-interkomowego-9-480x421.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"4-3-laboratorium-wyposazone-w-system-bezprzewodowy\">4.3 Laboratory equipped with a wireless system.<\/h3>\n\n\n\n<p>This example illustrates a team of doctors and nurses working in a laboratory and in an external control room.
