Stereo Tone Control with LM1036 circuit diagram

Stereo Tone Control with LM1036 circuit diagram

This is a stereo audio tone control circuit which build based on ICĀ  LM1036. This circuit will controll bass/treble level tone, volume and balance between right channel and left channel (input 1 and 2 ). You may use this circuit for stereo applications such as car radio, TV and audio systems, mp3 player, dvd player, ipod and more. An additional control input allows loudness compensation to be simply effected. The circuit should be works with supply voltage 9V to 15V DC.
