Default 5.1 amp

I am an electronics student trying to build a 5.1 surround sound amplifier for a school project. Does anyone know any good schematics to get a good idea from.

I think you can choose the TI's solution.
TAS5152+TAS5508.
of course, you should used 3pcs TAS5152 and 1pcs TAS5508.
That performance is better.

I would go with the Apogee chip set (STA308 or DDX8001) because I wrote software for it to control the biquads and volume control registers. The schematic is at this link:

The DDX parts are available from Gerberelec.com

An early version of the software to control the biquads is at this link:
http://www.audiodevelopers.com/Softw...ltichannel.zip

The software requires .NET 3.5SP1, and you will need to download the MSChart controls. The software controls the volume and the biquads, but it requires a microprocessor board that I could provide you. The microprocessor lets you control the amp via USB. The software isn't done, but most of the "hard stuff" is working and I'll have it all working fairly soon.

I would be interested if you are going to come up with a good board design. I have some other chips that I would like to add (such as digital delay)
