Bose Professional 834315-1110 ControlSpace EX-440C Conferencing Processor - 120V NA
Product Overview With an open-architecture, all-in-one design, the ControlSpace EX440C conferencing processor facilitates high-quality microphone integration and audio processing for small- to medium-size conference rooms. Various inputs and outputs allow for flexible configuration: four mic/line analog inputs, four analog outputs, onboard VoIP, PSTN, USB, Bose AmpLink output, eight-channel acoustic echo cancelling (AEC), and 16 x 16 Dante® connectivity. ControlSpace Designer software simplifies the setup process with drag-and-drop programming, making configuration quick and easy.
Key Features All-in-one design supports simultaneous VoIP, PSTN, and USB soft codecs in a single, 1RU model 8-channel advanced AEC with multiple references, routable to both analog and Dante inputs Adaptable noise cancellation on each AEC channel; non-linear processing and comfort noise to enhance the clarity and intelligibility of meetings Single-line VoIP with an internal web interface, allowing IT personnel to configure VoIP parameters without design file access or integrator involvement PSTN connection (RJ-11) for worldwide POTS/analog telephone systems USB connection facilitates easy integration with all soft codecs Dante audio networking includes 16 x 16 audio channels for connection to other Dante-enabled products, including native Dante-integrated microphones and amplifiers Bose AmpLink port provides 4 channels of uncompressed, low-latency digital audio to AmpLink-equipped Bose amplifiers GPI and Serial for external connections, such as fire alarm triggers and interfacing with control systems Front-panel interface features a large OLED display and rotary encoder for setting network parameters and monitoring channel activity.
