Re: need help

You may use LM1035 or LM1036 for this purpouse. Chip has tone, volume and balance control. All are DC controlable.
Another possible solution is clasicall, with discrete components.

This is LM 1036 using tone controlled preamlifier;

Bas control, treble control , balance control , volume control and loudness compensation......
