Description

This mono audio amplifier board, based on Class D topology and Sure Electronics’ T-AMP technology, delivers high output power as 400W into a 1.5Ohm load in 6’’ x 4.5’’ size, featuring high efficiency up to 95% 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 subwoofer, home theater, DIY audio, car audio, kiosk and demanding industrial applications. A DC24V – 36V power supply is required.

High Quality Audio Performance

Benefits from 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 performing well as 0.05% @ 1.5Ohm, 1W, 1kHz.

High Reliability and Long Service Time

To ensure sufficient heat dissipation for high stability and reliability, a low noise, temperature-controlled fan together with an optimized robust heatsink are mounted atop the amplifier board. It can work well even if in a harsh environment. 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 high power amplifier board supports WONDOM plug-in volume control module (VC01). You can adjust volume through the potentiometer board.
