Description


The amplifier adopts high class D amplifier circuit, and it is built in high-efficient power switch which enhances the efficiency up to 85%.


The product uses reasonable dissipation layout, which makes the amplifier can keep less than 55℃ even at severe working conditions, thus largely expanding its life span.


The amplifier is designed with rack mount in 1.5 U height and 19 inches. The output power of this series amplifiers are 120W, 240W, 350W and 500W.The rear panel provides with 4 channels 100V output terminal wiring speaker, a phoenix interface for remote control and monitoring equipment working condition.


Extensive protection includes high temp, overload and short-circuit.

 

 

Features


* Built-in powered band pass signal filter, Effectively filter out useless audio signal.


* 4 channel balanced line inputs, 4-channel 4 x 120W/240W/350W/500W power output.

 

* 4 channel separate volume control.


* 4 channel separate status indicators include signal, peak, protection and Led power supply.


* With power amplifier output normal condition monitoring, power amplifier standby control and power amplifier

standby cascade port.


* Power amplifier matches with DC 24V power supply terminal,and has the voltage protection within 21.6~26.5Vdc,

which avoids long-term supply for battery failure or damage of high voltage equipment.


* Speaker Output: 100V constant voltage


* With the electric isolation  of the equipments, and signal input and power amplifier output is also isolated in

electric, matching with 3C, UL, IEC60065 certificates.


* Extensive high temp, overload and short-circuit protection.
