This is a mono preamplifier circuit. Which it can use with various inputs. For example, microphone, tuner, CD and AUX. In the circuit above, IC741 is set into inverting amplifier mode. When a signal flows to AF in through C1 and R1 to pin 2 of IC1. Then, the signal goes out of pin 6. R4 acts as feedback resistors.

The integrated circuit audio amplifier has many advantages over amplifierswhich are built from separate, individual components. An IC allows more advanced circuits, with fewer components. A single IC can contain the equivalent of a score or more of transistors, diodes and resistors, matched and encapsulated together.
