about Dolby 5.1 decoder

Corsairr · 3rd December 2003, 11:55 AM

Hi DIYers !!!

I have a DVD player with a Digital Output (Coaxial and Optical) and only a stereo Analog Output. I'd like to know if I can build a decoder to obtain a 5.1 Analog Output (on 6 channels)? Does anyone can post plans of this decoder, please? I've already read all posts about the 5.1 subject, but I didn't find any solution to my problem

. Sorry if I missed one.

Thanks for answering me. Good luck!

Well, you can search www.zoran.com to find about decoder. The problem is: where can you buy the chips? I couldn't have find anywhere the chips, so, good luck !!!

Sorry for my english....

Thanks ... but data sheets about audio decoder aren't accessable

, do you have them ?
My first pb is not "how I can buy the processor" but "where can I find application data sheets"

thanks

They are not publically available.

You may want to check out the Smart Devices CS3xjr, it is an excellent analouge decoder for $129. (I've recommended this to a couple of people, I dont' work for them, just very pleased with their product). Circle surround is a big step up from normal dolby decoding.

If one insists on a DIY approach, there is a surround project on sound.au.com, the ESP website.

I did it another way...

I went downtown and found one of the stores selling out the obsolete Sony STR-SL5 receiver. It's a slimline design with 5x30W or so with a cooling fan. I got it cheap.

What's so nice with this receiver is that the power amp and power supply is separate from the rest. I intend to rip this board out and replace it with better power supplies and analogue outputs for external power amps.

There I have a complete preamp with DD/DTS and a radio to boot

. Including a remote control.

DIY is not always from scratch

Corsairr and all Decoder DIY player.

I have a board using YSS932 from Yamaha. Which support DD 5.1/ DTS.
I have all control code, and have complete function code in MCU, which depends on your taste.

I have similar post in TRAD post but delete and warning by someone. Should you have any problem, please direct email to:
