Description

LM386 Loudspeaker Amplifier

Supply voltage: 12V

Audio channel can be selected with the selector switch because this amplifier is mono audio amplification only!

PCB has volume slide, 10k potentiometer

Amplified voltage can be taken from the Terminal Block or from the Molex Connector, pay attention in the polarity!

Circuitry can be modified easily if different gains is needed or different speaker impedance is needed.

In this configuration the gain is around 50 and works with 8ohm to 16ohm speakers.

REVISION: 2.1
