3 Channel Equalizer Using LM324
How to make 3 Channel Equalizer settings? Come along follow this circuit.
Here I will post about 3 channel equalizer circuit using LM324 IC as the main amplifier in tone. The 3 tone is the tone of bass, treebel, and middle. Quite simple by setting the tone at a frequency of 108Hz - 108kHz. Equalizer circuit is working on asymmetric voltage 12 Volt DC, to produce a good sound quality and with low noise, required power supply voltage regulated properly.
The following circuit and its PCB design.
Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.
