A simple integrated amplifier

The head amplification of this machine adopts a standard compensation curve to amplify the head signal authentically
. The tone control part uses a common feedback control circuit . The difference is that a bass control frequency band is added to
enhance and attenuate the bass in order to obtain the best listening effect. The adjustment range of this circuit can be ±ZOdB. The tone control level
output After the signal adopts ( ;
.This
power amplifier circuit has a 40W×2 sine wave continuous power with a distortion less than o.0 5% .
