Is it possible to wire a volume/tone control circuit to this digital amp?

 

These controls would be in the preamplifier.

 

Probably. Care to be more specific?

I have a tpa3122 digital amplifier which I made from a kit from ebay. I will place the circuit and speakers into
a speaker box. I want to be able to add a volume/tone control circuit to the tpa3122 circuit. The volume/tone
control is a pre-amplifier circuit which I made from a kit from ebay. I want to be able to turn volume up/down
and adjust tone.
