Description

This 3CH high power audio amplifier board is capable of delivering 2 x 200W + 1 x 400W 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 95% 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 – 46V 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 95dB and THD+N performs well as 0.008% @ 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.

Full Set of Solution

This high power amplifier board can connect with WONODM Volume control board, Bluetooth receiver board or DSP kernel board for more functions assembly and better expandability. To prevent common ground noise in connection condition, it is recommended to power the boards with separate power supply or connect the “GND” of two boards.

QUESTIONS & ANSWERS

Hi, can you connect a dps or eq and volume to this board without causing any noise ?

Hi, Charlie. Thank you for your interest in our products. Since the gain of the high power audio amplifier is high, even the tiny noise would be amplified into big noise. We are working on a new version APM for better connection with high power audio amplifiers. It is recommended to buy JAB5 for now, which is a 4 x 100W audio amplifier board integrated with both Bluetooth 5.0 and ADAU1701 DSP and can be configured as 2.1 / 2.0 mode. Wish this could help you.

which kind of power amp chip you have used in you amp board and also let me know how many power amp chip been used of each channel.

Hi, Habib. Thank you for your interest in our products. The power amp chip used in this product is STA516BE. There are two power amp chips on the board, one chip for stereo output (2 x 200W) and other for mono output (1 x 400W). Wish this could help you.

Hello, do you have an indication when you will release the parallel solutions for battery boards and special boost board for battery board?

Hi, Marco. Thank you for your interest in our products. The products are under strict test now. We are planning to release them in 1-2 months. Please stay tuned.

Hello, can i use this board with 300W BOOST CONVERTER TL494 to power with battery module S5 BCPB4 ?

Hello, Marco. Thank you for your interest in our products. We have employed current limit circuit on BCPB4 for safety, therefore BCPB4 cannot provide enough continuous power to power for the amplifier board. We are working on the parallel solution for battery boards and will release it soon. And we are going to release a boost board specially designed for use with battery board. Please stay tuned.
