Because of licencing issues, if you want "official" formats you pretty much need to start with an existing unit.

I think he meant the search engine of this site has issues with 5.1 as predicates.
You could buy a super cheap 5.1 receiver and just remove the Dolby Digital/DTS circuitry from it. However, I don't know how complex these circuits are, and I don't know if you'll be able to find white papers on the IC(s) to figure out how to make it suit your needs. The better method would be to by a DVD player with an onboard decoder (don't they all have them now?) and either an optical/coax digital out, which you can set to a raw 5.1 PCM output, or better yet, one with 6-channel analog outputs. The 6-channel PCM-out would require a separate, multi-channel DAC, which would be expensive, whether you make it yourself or not.
Another source for the Decoder chip(s) would be the DVD player itself, but I would expect it to be easier to figure out how to use it if you get it out of a home theater receiver circuit. Anyway, it wouldn't be easy, but it might be fun.

It seems like we should be able to buy a decoding chip that includes the Dolby licensing fee.
Or is this too logical a thought?

This thread is getting 'jacked. This has been discussed in the past, and nothing wrong with starting a new thread either 🙂

Nah, just a little digression. A lot of people are using the kits to make multichannel amps, so it's all related.

Do you have an answer to us that is drooling over the nice pictures of your PCB's and missed the first group buy, will there be a phase 2?

It is a 6 channel volume control board that controls the volume for the four amplifiers in this case as well as an RCA output for subwoofers etc.

What's the word on the balanced-bridged 200 to 300 watt Gain clone PCB's Brian?
It would be nice to have a new PCB rather than wire 6 boards together per channel. A single strip maybe with 3 OPAMPS on either side. with the caps in the middle. I have some perfect Heat sinks for this configuration. 🙂 🙂 🙂

Are you saying you want boards for a Concentraclone?
The LM3886 is probably better than the LM3875 for this task... but I am still planning on trying it out with my boards and the LM3875. I would have tried it out yesterday, but I am still recovering from a cold and needed to rest.

If the bridged amplifier were made out of a cluster of BLB (Brian’s Little Board),
It could be called the Contatenclone. I may be alone in this, but I kind of like the idea of mating the BLB to some form of a motherboard to build bridged amp.
PHilgeman,
Are those VCA's that you’re using for volume control?
Thanks.
