This 4CH 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’s T-AMP technology, featuring high efficiency up to 95% and high sound quality with low distortion and low noise level. Easy installation, mid power output and high reliability make this audio amplifier board suitable for home audio, DIY audio, car audio and demanding industrial applications. A DC15V – 27V power supply is required.

4-channel Audio Amplifier Board

This audio module provides 4 output channels, each of which delivers 100W output power into a 4Ohm load, making it applicable to audio 4.0 systems.

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 90dB and THD+N performs well as 0.03% @ 4Ohm, 1W, 1kHz.

High Reliability and Long Service Time

A low noise cooling fan together with an optimized robust heatsink are mounted atop the amplifier board to effectively decrease the temperature. 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. Active indicator is provided on board for customers to have an overview of the operating status of the amplifier board.

What is the maximum power (watts) output at 0.1% THD?

Hi, Joe. Thank you for your interest in our products. The maximum output power is around 30W at 4Ohm, 0.1% THD. Wish this could help you. Have a nice day~

Hello, are there different versions? Here I read T-AMP AA-AB33182 max. 27VDC. In EU (France), I ordered this one: WONDOM STA516B 4CH (AA-AB33182) and read: 15-36VDC Is 36VDC ok and best use? (with PS-SP12148 TL494 500 W DC DC Car Audio Boost converter)

Hi, uwe. Thank you for your interest in our products. 36V is the maximum power supply voltage and 27V is the typical value for AA-AB33182. Wish this could help you.
