Power Audio amplifier  2. 1 (2 Front + 1 Subwoofer) Circuit Diagram

Front Stereo Audio amplifier

Audio amplifier circuit schematic role is to amplify the sound signal for a stereo channel front. Scheme audio amplifier circuit comprising the two sides of the front of the mouth in the wake amplifier IC TL072 wearing. 4558 & audio power amplifier circuit schematic that in the wake wearing as power IC TDA1521 stereo amplifeir.

Subwoofer Audio amplifier 

Subwoofer audio amplifier circuit schematic role is to amplify the sound signal sounds super bass (subwoofer). are circuit scheme is divided into two sides of the low-noise filter (super bass) who in the wake of the second unit in the operational amplifier IC TL072 / RC4558 ( or you can using this circuit Subwoofer Booster 4558 ) and hand power audio amplifier with TDA1521 IC which are configured by bridge to drive the subwoofer speaker.
