The CX-PA1120 is a 120 W multi-zone power amplifier designed for the CX-1000 series IP communication system. With a built-in 10-zone speaker selector, it enables audio broadcasts from each intercom station and audio interface to individual speaker zones. Chime and EV broadcasts can be triggered from the unit's built-in memory, while input and output volumes are adjustable via front-panel knobs or software.
Equipped with 2 balanced audio inputs (including phantom power on input 1), 10 balanced speaker outputs with selectable 100V/70V output, and 1 recording output, the CX-PA1120 offers flexible signal management. Advanced DSP processing includes Gain, EQ, Compression, AGC, Trim, Gate (VOX), and a built-in ANC function that adjusts output based on ambient noise when connected to an ANC sensor microphone.
Even without a connection to the System Manager, emergency all-zone broadcasts can be made via the amplifier's inputs and outputs. Front panel direct keys and LED indicators provide intuitive control, while dual RJ45 connectors support key network protocols, unicast/multicast audio transmission, and full integration with the CX-1000 IP system. Ten high-capacity control inputs and outputs enable integration with external devices, making this amplifier ideal for commercial and institutional installations.
