Power Amplifier 240W 10SS

CX-PA1240

The CX-PA1240 is a 240 W amplifier unit equipped with a built-in 10-zone speaker selector, designed for theCX-1000 series IP communication system. It allows audio broadcasts from each intercom station and audio interfaceto each speaker zone. By registering audio files in the unit's built-in memory, Chime broadcast and EV broadcastcan be made. It is equipped with 2 analog inputs, 1 recording output, and 10-zone speaker output which is individuallycontrollable. The input and output volumes can be adjusted using the front panel-mounted volume knobs or bysoftware. The sound quality of the input and output can also be adjusted by software. The CX-PA1240 is equipped with24 V DC emergency cutoff input function, allowing it to be linked with emergency evacuation broadcast equipment. It features a built-in ANC function that automatically adjusts the output volume according to the ambient noise when an ANC sensor microphone is connected. Even if the connection to the System manager is disconnected, emergency all-zone broadcasts can be made using the unit's audio input and output. Broadcasts and various functions can be started and stopped using the front panel-mounted direct keys.
