Description
This stereo mid-power audio amplifier board is capable of delivering 200W output power per channel into a 3Ohm load based on Class D topology and Sure Electronics’ T-AMP technology, featuring high efficiency up to 91% and high sound quality with low distortion and low noise level. Compact size, easy installation and mid power output makes this audio amplifier board suitable for home audio, DIY audio, car audio and demanding industrial applications. A DC15V – 26V power supply is required.
High Quality Audio Performance
By means of dedicated PCB layout design and engineers’ attentive debugging, this mid-power audio amplifier board features such high audio performance that you can get pure enjoy of the music, whose SNR reaches 94dB and THD+N performs well as 0.004% @ 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. Full protection circuit, like over temperature protection and overcurrent protection, is equipped on this board for high reliability and long 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. Power and clip indicator are provided on board for customers to have an overview of the power condition of the amplifier board. Shutdown function is offered for simple control of the amplifier board.
External Volume control
This mid-power amplifier board supports WONDOM plug-in volume control module (VC01). You can adjust volume through the potentiometer board.
