Best AudioTone Control Circuit Diagram

This is the Best AudioTone Control Circuit Diagram. This simple and best AudioTone Control can be acclimated in may audio applications. It can be added to amplifers, acclimated as a angle abandoned ascendancy module, or alike congenital into new and agitative instruments. It's one IC architecture makes it a actual bunched circuit, as alone a few abutment apparatus are required. Plus, it does not use a bifold ability supply. This agency that the ambit will run from 9V to 15V (although the bass will be a little anemic at 9V). The ambit is by Robert Barg and originally appeared in the Think Tank cavalcade of the May 1998 affair of Popular Electronics.

NOTES

S1 is a contour control. Volume is controlled by R11. Balance is controlled by R10. R9 and R8 control bass and treble, respectivly.

J1 is the left input, J4 is the right input. J2 is the left output, J3 is the right output.

The circuit is designed to accept line level or mic level inputs. if you are going to be using a stronger signal, a voltage divider will be necessary to cut it down to proper levels.

You can, of course, skip J1-J4 if you plan to integrate this circuit into another.
