It is a Class-D digital amplifier which is used for the voice signal broadcasting in EVAC system.And it is a 2U device that integrates 4 independent PFC functions, a power-saving control module, and the 120W/240W/350W/500W power amplifier with DC24V power interface, 2 channels.
* Modular design, easy to configure as required.
* The use of efficient class-D digital power amplifier design scheme has lower power consumption.
* 2U design, 2 independent channels, each channel 120W/240W/350W/500W.
* Overload, short circuit protection, automatic temperature control.
* Automatically detect the working status of each channel and indicate by LED.
* Support power saving mode, enter standby mode when there is no signal.
