The CX-PA1240 is a 240W networked power amplifier with a built-in 10-zone speaker selector, designed for the CX-1000 IP communication system. It enables audio broadcasts from intercom stations and audio interfaces to individual speaker zones, supporting 10 balanced outputs with selectable 70V or 100V line voltage.
Equipped with dual balanced audio inputs, a recording output, and advanced digital signal processing, the CX-PA1240 provides precise audio control. DSP features include gain, EQ, compression, AGC, trim, gate (VOX), and Automatic Noise Control (ANC) that adjusts output levels based on ambient noise. Volume and sound quality can be adjusted via the front panel or software.
For reliable operation, the CX-PA1240 supports emergency all-zone broadcasts even if disconnected from the system manager. Additional features include 10 direct keys with LED indicators, high-capacity control inputs and outputs, and an emergency cutoff input. Dual RJ45 network ports support unicast and multicast audio transmission, making the CX-PA1240 ideal for commercial facilities, schools, and industrial environments.
