Description
The heart of the circuit is TDA7294 which acts as an amplifier the right
and left input feded from the pre amplifier circuit is amplified after
passing through the noise filter which contains an RC circuit, the
volume is controlled by the variable resistor 47k. and the automatic
gain control is provided by the operational amplifier circuit opp amp
IC249 For both right channel and left channel., the speaker used is an 8
