Stereo Tone Control Circuit Diagram With Pcb Layout. Stereo tone control circuit is used to adjust the tones before entering the audio power amplifier. Pre tone control stereo using ne5532.
One for line stereo one for microphone and has control of the three audio frequency high treble medium and low bass. In this design we have two inputs. This is an active stereo tone control circuit using very well known op amp ic of tl072.
Then the signal is amplified and amplified by the u1 ic dual op amp buffer circuit you can use equivalent dual op amp ics for example jrc4558 tl082.
The circuit include mic pre amp and mixer control. Stereo tone control over equipped with a loudness and filter directly without using the switch to disconnected or connected. For pcb layouts square pads can indicate several things. You can also check out the other bass treble circuits which we have build earlier.
