The amplifier adopts high class D amplifier circuit, with 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 U height and 19 inches.  The rear panel provides with 2 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.


* 2 channel class D digital power amplifier, 2 independent channel without transformer output is 100V.

* The rear panel is equipped with a “ground” line suspension switch, which effectively eliminates the loop noise caused by the connection of the “ground” lines of multiple equipment signals.

* 85% high efficiency amplifier, low power loss, low heat.

* 2 channel European terminal balanced input, 2 channel European terminal output.

* Remote control of power-on function: remotely turn on the power of the machine, and disconnect the power of the machine when both functions are turned off at the same time.

* Fault output function, remote monitoring power amplifier working state.

* 2 channel independent 24V standby power inverter function, power amplifier with voltage limit, short circuit, overload, overheat protection.

* AC 110V or 230V and DC 24V optional.
