10 Channel Equalizer using 4558 IC

10 Channel Equalizer using 4558 IC

In this post, I will share about the equalizer for audio power amplifiers, more precisely the 10 Channel equalizer circuit. I designed this equalizer circuit using the op-amp 4558 IC as a signal amplifier that is regulated by capacitors and resistors. And the component that I use is the SMD component, why do I use the SMD component? because it can reduce the PCB dimension and reduce the noise level because the PCB path that can be pressed is as close as possible. For this 10 channel equalizer circuit scheme you can see below:

This equalizer circuit requires a symmetrical power supply of at least 12V to 15Volt, and settings ranging from RV 1 starting from 30Hz, 64Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 20kHz.

For PCB layout I use a double layer using  60mm mono potentiometer. Following PCB Layout for 10 Channel Equalizer:
