Product Description

EN54 Public address and voice alarm system high power digital class D Amplifier 500W supports 70V/100V audio powerful amplifier outputs  mininova
 

PA-AMP500 public address and voice alarm system high power digital class d Amplifier 500W supports 70V/100V audio outputs

PA-AMP500 high efficiency power amplifier provides audio signal amplification for the INTEVIO voice alarm and public address system. It is reliable, efficient and light in weight.

 

Functions:

Input/output

PA-AMP500 supports balanced / unbalanced audio inputs and 100V/70V speaker outputs. It also has a 100V audio input port to connect with the output from other amplifier so that the output power can be increased easily. A contact output is provided to send out the fault status to 3rd system when a fault is detected. Through the RJ45 port, PA-AMP500 receives the audio signal and control signal from the controller PA-MCU or the zone expander PA-ZONE8 / PA-ZONE24 and sends back the fault status.

 

Automatic fault detection and self-protection

PA-AMP500 can self-protect from overheat, overcurrent, overvoltage, undervoltage, overload and short circuit. For example, when the internal temperature reaches its critical limit, the overheat protection circuit will shut down the power amplification module and activate the protection indicator light on the front panel. PA-AMP500 can detect power supply errors automatically during operation. The built-in fuse will provide overcurrent protection to the main power supply. When a shout circuit is detected in the main power circuit, the power will be automatically shut down and the backup power will then be enabled to replace the main one.

 

Features :
