idea: Cheap Dolby Digital Receiver Conversion

nobody special · 12th February 2003, 06:23 PM

I have a Sony receiver with Dolby digital. I was considering removing the power amp, cleaning up the power supply, and building in 5+1 channels of zen balanced line stage, or something similar. Has anyone here tried something like this? Is this idea even worth considering? Seems like it could work. Then I would just build a decent 5 channel amp to go with it. Any thoughts on this idea?

This sounds like a good idea!

If you feel like you could even replace the internal DACs, add a low jitter clock or add async reclocking to get even better results.

Sounds good, but I'm a digital dummy know-nothing.

Maybe I cold find some help here though.

Should work out fine. I suspect you may find a lot of functions are integrated into one board, but you can always just cut the traces to the power-amp section if necessary and cram everything in.

Implementing the bal line stage internally means you can also omit all the input protection components without fear.

I think this decoder costs less than $100 US. Ive been thinking about this or one of a few similar devices marketed for desktop computing as the decoder for a similar project.

Tiroth,
I figured I would have to create some new take-off points on the boards, as integrated as everything is. Input protection may have to stay, as I plan to implement at least 1 or 2 input as "direct" , bypassing all the nasty Sony processing.

Da5id4Vz,
That's kind of neat... may be a better way to go.
