Preamplifier Ic 4558 Preamp Circuit Diagram. Hello all friend to today i would like to show about ic 4558d audio volume controller circuit bass circuit 4558 simplest audio amplifier circuit thank. This mic preamp uses the low noise ic ua739.
Power supply symmetrical 15vdc. 4558 ic audio power amplifier circuit diagram. The active subwoofer function to filtering bass tones low and add settings for low tones frequency ranging from 20hz up to 70hz on audio signal input output the settings contained in the pot stereo that you can see in the picture circuit schematic.
The input signal is the various types of up to 4 inputs.
This is a multi purpose ne5532 preamplifier circuit. The active subwoofer function to filtering bass tones low and add settings for low tones frequency ranging from 20hz up to 70hz on audio signal input output the settings contained in the pot stereo that you can see in the picture circuit schematic. Use 20v to 60v for operating this circuit. The circuit is a simple two transistor pre amplifier using a feedback loop for enhancing the amplification.
