Default need 5.1 Channel Audio Volume Controller

hi all,

I am going to make an Audio Amp with TDA 2030 IC to fit in my DVD player. it will be 5 Mono channel for Front Left/Right, Rear Left/Right and Center. and one Dual IC for Subwoofer. The question is, is there a Audio volume controller circuit to control volume of all 5+1 channels all together.

i want to avoid the 4 controls ( 2 Stereo and 2 Mono) and instead put one for all. can anyone help me

The input will be 5+1 seperate audio from the DVD player.

I would recommend the Analog Devices SSM2160 6-Channel, Clickless Serial Input Balance/Master Volume Control. The specifications look very good and the price is not so bad either.

The SSM2160 requires a microprocessor to control it.
Some alternatives:
