Compact yet powerful, the Senator 900 system combines a fully integrated digital conference, AEC distance and web conference system into a single DSP unit. Featuring a single DCP900 processor, it can connect up to 64 DCA660 digital 6 Ch. ampli ers and 100 delegate units in a redundant loop or two daisy chains, with each chain is capable of handling up to 50 delegate units. The system o ers state-of the-art audio quality with microphones that can be individually processed with AGC, 6 bands PEQ, Level Gate, Hi/Lo Pass Filters, Feedback Suppressors and Gain-sharing Auto Mixers and AEC (RAPIDO™ Echo Cancellation). Harnessing the industry latest technology, Mix-minus auto calibration, it automatically adjusts the suitable parameters and prevents feedback. This is bene cial for the initial system setup and when there are changes to seating arrangements in the room. The Senator 900 system supports the simultaneous activation of a NOM (Number of Open Mics) of 8 delegate units (the NOM is changed to 4 if the AEC is enabled). The processor comes with a balanced Line In/Out channel that allows you to either connect to a microphone and audio mixer, or integrate the Senator 900 system to an existing video conferencing system (optional AEC-card required). Furthermore, the DCP900 includes a stereo line In/Out that feeds the system with any audio source or connect to an audio recorder. Containing a RS232 and RS485 port to facilitate 3rd party control (via cameras, projectors, etc.), the DCP900 uses the VoIP function as an AEC web conferencing tool via SIP protocol if the optional AEC-card is installed on it. In addition, the USB port at the front of the DCP900 facilitates the seamless recording of conference proceedings, automatically creating time-stamped recordings in MP3 format. Furthermore, the system allows for the integration of up to two simultaneous translation channels. Controlling and conguring of the entire Senator 900 system, including the DSP parameter adjustment and other audio management is easily done via a web browser. In addition, the versatile Senator 900 system allows you to select between ve di erent conference modes (FIFS, FIFO, Priority, Delegate Request and Chairperson). In addition, the Senator 900 system meets high level of full-redundancy. One DCP900 can act as a primary DCP900 processor, the other can act as secondary DCP900 processor. In case the primary DCP900 processor breaks down, the secondary DCP900 processor will automatically switch over and make sure the SENATOR 900 system continues operating.
