ControlSpace EX-440C
conferencing processor
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
