Product

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 and 350W and 500W. The rear panel provides with 4 channels 100V output terminal wiring speaker, and a RS232 connector for remote volume control, remote product condition reading and remote standby control. 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 4×120W/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.

* With RS232 interface for remote control control switch machine and remote monitoring power amplifier working condition. Capable to  achieve 4 channels power amplifier volume control adjustment, fault output feedback and trigger amplifier function etc.

* 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.
