LM 386 general description:
This circuit is a signal line so that you reinforce a small speaker can drive with. The LM 386 is a number of versions available. The LM 386N-1 can deliver a power of 325 mW, the LM 386N-2500 mW, the LM 386N-3700 mW and LM 386N-4 can deliver one watt output. All versions can be used in the circuit. Using S1 is a bass boost (extra bass enhancement) to turn. The state is drawn from the bass-boost.
