Next-generation OCP technology

SSL Live represents decades of experience in creating the best studio consoles implemented to the specific requirements of live sound production. The result is an intuitive and ergonomically efficient design, with a set of unique features that give the performer complete control. The system allows operation from both a touchscreen and control surface. A single, ultra-bright, high-resolution 19-inch multi-touch screen is the heart of the console and can be used to configure both the system and routing, as well as create customized control surface layouts using a layer manager, automation interface, effect rack and two different views: channel view and console overview.

Architecture
The L450's DSP is built on next-generation Optimal Core Processing (OCP) technology and is extremely flexible. The console has 856 inputs and 856 outputs. It has 240 mixing channels at 96 kHz. These channels can be assigned as Inputs, Stem Groups, Auxes and Masters as needed and configured from mono, which uses one track, to 5.1, which uses six tracks.

The 32 input / 36 output matrix also has its own dedicated processing and can be split into four separate smaller matrices if needed. All 36 output tracks of the matrix have available high and low pass filters, 4-band EQ, 2-second delay and unique all-pass filters. This is in addition to two inserts that can be used with both the internal Effect Rack and external devices.

Local and external mic/line preamps use SSL's patented technology to deliver the highest quality signal to the console. The circuits are DC-coupled (no electrolytic capacitors in the signal path) and have high input impedance. The gain of the microphone preamp is controlled extremely precisely in over 16,000 steps, providing completely smooth regulation and extremely low distortion. See for yourself by conducting listening tests.

L450 local analog I/O configuration: 16 microphone/line inputs, 16 line outputs, 2 headphone/monitor outputs. AES/EBU digital I/O configuration: 4 pairs of inputs and 4 pairs of outputs. AES/EBU inputs/outputs have fully variable sample rate conversion.

Standard MADI port configuration: 6 redundant coaxial and 2 fiber-optic (non-redundant) pairs. If redundancy is not required, these connections can be independent, providing a maximum of sixteen ports. In addition, a separate optical MADI port (out/in) is available, designed for use as an "FX loop" to connect an external FX device, such as a system using Waves Multirack or a VST effects host. The standard configuration offers SSL Blacklight II connectors. A Dante card is also available, offering 32x32 channels of I/O at 96 kHz (or 64x64 channels at 48 kHz) via a redundant Dante connection. A redundant pair of SSL X-Light connectors provides 256 bidirectional channels at 96 kHz between the console and stage via a single cable with reinforced connectors. There are also MIDI, LTC, Wordclock and GP I/O connectors on the rear panel. The console has redundant power supplies.
