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 x 64 audio channels for connection to other Dante-enabled products, including native Dante-integrated microphones

Bose AmpLink port provides 8-channels of uncompressed, low-latency digital audio to AmpLink-equipped Bose 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
