BOSE PROFESSIONAL CONTROLSPACE EX-440C
Bose Professional ControlSpace EX-440C
Conference Processor
Thanks to its open architecture and all-in-one design, the ControlSpace EX-440C conference processor simplifies the integration of high-quality microphones and audio processing in small and medium-sized conference rooms. A variety of inputs and outputs allow for flexible configuration: four analog microphone/line inputs, four analog outputs, built-in VoIP, PSTN, USB, Bose Professional AmpLink output, eight-channel acoustic echo cancellation (AEC), and 16 × 16 Dante connectivity. The ControlSpace Designer software simplifies the configuration process with drag-and-drop programming, making setup quick and easy.
Key features:
- The „all-in-one” design supports VoIP, PSTN, and USB soft codecs simultaneously in a single 1RU model.
- 8-channel advanced AEC with multiple references, routable to analog and Dante inputs
- Adaptive noise reduction on each AEC channel; nonlinear processing and comfort noise to enhance the clarity and intelligibility of meetings
- A single-line VoIP device with a built-in network interface, allowing IT staff to configure VoIP settings without needing access to configuration files or the involvement of an integrator
- PSTN connection (RJ-11) for worldwide POTS/analog telephone systems
- The USB connection facilitates integration with all software codecs
- The Dante audio network supports 16 × 16 audio channels for connection to other Dante-compatible products, including native microphones and Dante-integrated amplifiers
- The AmpLink port provides 4 channels of uncompressed, low-latency digital audio to Bose Professional amplifiers equipped with AmpLink.
Application:
- Small/medium conference rooms
- Courtrooms
- Remote learning
