（AA-AB32971）
Picture Showcase

Description

This stereo mid-power audio amplifier board is capable of delivering 100W output power per channel into a 4Ohm load based on Class D topology and Sure Electronics’ T-AMP technology, featuring high efficiency up to 93% and high sound quality with low distortion and low noise level. Easy installation, mid power output and high reliability makes this audio amplifier board suitable for home audio, DIY audio, car audio, home theater and demanding industrial applications. A DC15V – 27V 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 high audio performance, whose THD+N performs well as 0.003% @ 4Ohm, 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.
Supporting External Volume Control Board VC01

There is pins on AA-AB32971 for external volume control board – VC01. You only need to plug the VC01 board into the pins, which is very easy and convenient. VC01 is an optional module.
