A flexible DSP platform for scalable systems, ControlSpace EX conferencing processors have the features to support rooms of various sizes and the flexibility to meet future needs. With an open-architecture, all-in-one design, the ControlSpace EX-1280C offers signal processing for integrated-microphone audio conferencing applications. As the highest-capability processor of the ControlSpace EX family, the EX-1280C includes 12 mic/line analog inputs, 8 analog outputs, 8 AmpLink digital outputs, 12 acoustic echo cancellers (AEC), and 64 × 64 Dante connectivity. ControlSpace Designer software simplifies the setup process with drag-and-drop programming, making configuration quick and easy.
All-in-one design supports simultaneous VoIP, PSTN and USB soft codecs in a single 1RU model
12 acoustic echo cancellers (AEC) route to both analog and Dante inputs; multiple references allow one EX-1280C processor to support multiple rooms or AEC-sharing across multiple processors
Adaptable noise cancellation on each AEC channel; non-linear processing and comfort noise to enhance the clarity and intelligibility of meetings
2-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 PC soft codecs
Dante audio networking supports 64 × 64 audio channels for connection to other Dante-enabled products, including native Dante-integrated microphones
AmpLink port provides 8 channels of uncompressed, low-latency digital audio to AmpLink-equipped Bose Professional amplifiers
Front-panel interface features large OLED display and rotary encoder for setting network parameters and monitoring channel activity
GPIO (5 in/5 out) for external connections including microphone pushbuttons or driving microphone LEDs
Designed for a wide range of applications, including:
Performance venues
Stadiums and arenas
Places of worship
Resorts and Hospitality Venues
