2 x 300Watt+1 x 500Watt Class D Audio Amplifier Board - T-AMP -STA516BE

This 3CH high power audio amplifier board is capable of delivering 2 x 300W + 1 x 500W output power into a 3Ohm load in 6’’ x 4.5’’ size based on Class D topology and Sure’s T-AMP technology, featuring high efficiency up to 97% and high sound quality with low distortion and low noise level. Easy installation, high reliability and multichannel high output power makes this audio amplifier board suitable for audio 2.1 system, soundbar, home theater, DIY audio, car audio, kiosk and demanding industrial applications. A DC24V – 50V power supply is required.

High Quality Audio Performance

By means of dedicated PCB layout design, engineers’ attentive debugging and careful components selection, this multichannel high power audio amplifier board features high audio performance with SNR reaching 91dB and THD+N performs well as 0.01% @ 3Ohm, 10W, 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. RCA jack and line input are offered for simple connection. Clip indicator is provided on board for customers to have an overview of the running condition of the amplifier board.
