Make 5 Band Stereo Parametric Audio Equalizer Using 10 Transistors & 4558 or NE5532 IC | LA3600 

This five-channel graphic equalizer is 100% substitution for LA 3600 or Ka2233 graphic equalizer. The schematic circuit diagram followed, and the PCB layout used to Build this stereographic equalizer, 5 band or 5-channel monographic equalizer can be built in that PCB.
A total of 10 C2120 or equivalent NPN transistors are required to construct the graphic equalizer.
It will be a high-performance graphic equalizer. This graphic equalizer's high pass filter, low pass filter system, and mid-range audio frequency control capacity are unmatched.
This graphic equalizer's high pass filter, low pass filter system, and mid-range audio frequency control capacity are very high quality.
This graphic equalizer is excellent for boosting the Bass, controlling the Treble, and maintaining Mid-range audio frequencies.
