Description

This stereo audio amplifier board, based on Class D topology and Sure Electronics’ T-AMP technology, delivers high output power as 400W per channel into a 3Ohm load, featuring high efficiency as 92% and high sound quality with low distortion and low noise level. Easy installation, high reliability and high output power makes this audio amplifier board suitable for soundbar, home theater, DIY audio, car audio, kiosk and demanding industrial applications. A DC24V – 44V power supply is required.

High Quality Audio Performance

By means of dedicated PCB layout design and engineers’ attentive debugging, this high power audio amplifier board features high audio performance with SNR reaching 93dB and THD+N performs well as 0.013% @ 3Ohm, 1W, 1kHz.

High Reliability and Long Service Time

A low noise, temperature-controlled fan together with an optimized robust heatsink are mounted atop the amplifier board to ensure sufficient heat dissipation even in rough environment, so you don’t need to worry about overheat. Full protection circuit, like over temperature protection and overcurrent protection, is equipped on this board to ensure longer service time.

Easy for Installation

Four screw holes provided make this amplifier board easy for installation and quick for integration in any cabinet. Thanks to the pre-mounted industrial terminal interfaces, all you need to do is to plug in cables for connection, without any demand of soldering, which is swift and convenient. Clip indicator is provided on board for customers to have an overview of the running condition of the amplifier board. Shutdown function is offered for simple control of the amplifier board.

External Volume control

This high power amplifier board supports WONDOM plug-in volume control module (VC01). You can adjust volume through the potentiometer board.
