Preamplifier Ic 4558 Preamp Circuit Diagram. The connected 100k pot on the left and right input of the circuit will allow adjusting the input signal. In this circuit one ic 4558 and 4 power transistors are used with some discrete components.
The circuit is based on 2 4558 opamps with the main audio input and bass output volume adjustment. Use 20v to 60v for operating this circuit. The microphone preamplifier circuit design presented in this schematic use ssm2015 produced by precision monolithics inc.
For the 2 1 amplifier project i prepared a 4558 opamp preamplifier subwoofer filter circuit.
The circuit is an example of how a good. This is a single channel audio amplifier circuit. Low noise audio preamplifier circuit. This circuit is given by emmanuel.
