Welded 8P op amp IC Block, easy to replace the op amp to enhance playability, CBB capacitance capacitors are original, high-quality sealed potentiometers potentiometer.
There are LED lights, real-time monitoring the power supply situation. Input voltage: positive and negative dual power input AC 12v to 15v can be.
It can be a single / dual channel input and mono output. PCB ultra hardness FR-4 fiberglass board, size: 78x42mm, thickness: 1.6mm.
Frequency adjustment range 22Hz-210Hz, this frequency range is no human voice, so-called low-pass only the low-frequency output, to be added after stage amplifier power amplifier board can be used. The intensity of low-frequency performance and power amplifier board with speaker matching, please choose a different amplifier board and subwoofer (passive subwoofer) according to different occasions.
Input voltage: positive and negative dual power AC 12v to 15v .
It can be a single / dual channel input and mono output.

Quick tips:

1. Please plug the power cord into the amp THEN the wall, plug the audio cables into amp THEN switch on.

Some customers may see some slight sparks flying when they plug the power supply into the amplifier, because they use it in wrong way, you need to connect the amp to the power supply first, then plug the power supply into the 110v AC outlet, don’t worry about the sparks, because this is class d amplifier, the capacitors need to charge when the power in, it’s normal and safe.
