Volume Controller Equalizer with using LM1036

This volume controller equalizer electronic project is designed using LM1036 DC tone volume controller with volume and balance circuit for stereo applications .An additional control input of the LM1036 allows loudness compensation to be simply effected.

Volume Controller Equalizer Circuit diagram

The four control inputs of the LM1036 volume controller provides control of the bass, treble, balance and volume functions through application of DC voltages from a remote control system or, alternatively, from four potentiometers which may be biased from a zenner regulated supply provided on the circuit.Each tone response is defined by a single capacitor chosen to give the desired characteristic.


What is the rating of the capacitors at the outputs?
Why do some of the capacitors have a rectangle on one side? Are they electrolytics?


For those building this circuit, I made a parts list:
47k x4
47k pot x4

0.01uF x2
10uF x2
0.47uF x2
0.39uF x2
0.22uF x4
10nF x1
47uF x1
