Descriptions:
In building a car audio system or a professional home speaker, you need an independent stereo sound output along with a subwoofer sound output filtered by a low-pass filter circuit, and this module has all these things. 80 W stereo amplifier module to increase power currents are used and their main task is to improve the sound of the system and strengthen weak signals.
From the input side of this module, the first potentiometer is for adjusting the sound intensity (volume), the second potentiometer is for high frequency (treble), the third potentiometer is for medium frequency (Alto), the fourth potentiometer is for low frequency (bass).
Application:
Amplifiers are used in music equipment, electronic devices such as television and radio receivers, audio equipment and computers to increase the signal range.
