Default 3 channel class d amp with tone control

Hi,

I am looking for a three channel (2.1) class d amplifier with approximately 25 watts per channel (@ 8 ohms). The tone control should consist of bass, treble and volume. I would like to build am boombox with this.
A diy kit would be perfect. Have you guys seen anything like this?

Thanks

eladmi

I have one, but it's a future project.

Hi,

i just bought a T2 board via ebay. I think I will wait until you have finished the 2.1 design ; ) . Can you recommend a tone control for the T2 board?

regards eladmi

You can check if LM1036 meet your need, but that will bring more noise to your system in same time. There are also some other solution like building with OPA.
