Default Subwoofer controller

Hi there.

I need a subwoofer controller for may home made 2.1 amp.

What I need is to take both L and R channels, mix them into a single mono channel and control the gain and maybe the frequency cut around the 100hz (not necessary, but wold be good)

Does anyone know a project supplyed by 12v?

well, I already saw these projects, but they need a +15 0v -15v rail.

I only have available a +12 0v and a +33v 0v source.

if I could change these power supplyes to +15 0 -15 it would be nice too.

ps: sorry about the typing error on subEwoofer

Split your +33V rail like this:

If you don't draw too much current, this works quite okay

Cheers, Paul
