Description
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
