I'm not sure how unique of a problem this is.

I'm looking to distribute digital audio to four rooms from my central receiver that has one digital out (PCM, coax, RCA connector). From what I can tell, a normal composite video distributor/amplifier should work given the frequency, but the cheapo one from Radio Shack didn't work.

Any thoughts?

Regards,
Raymond

I'm not familiar with the amplifier in question but will it operate down in the range the pcm audio works. There are also timing and sync factors the amplifier may not handle properly

I'm have a Proceed AVP2 preamp, and checked the manual for any specs on the digital out and here is all that I found:
- 1 digital output RCA (S/PDIF electrical)
- Digital output impedance: 75? (S/PDIF electrical)

I know that I can run the digital out from the pre-amp to another digital-in on a receiver in another room and it works fine.

Trying to go to more than one room is the problem, I can't figure out how to "split" the digital out signal. There is 1 product I found that could work, the link is below, I just don't like the price very much.

thanks a lot,

Raymond...there are ways to do it with optical outs..and optical/coax converters...

The problem you are probably having is this...you are injecting a badwidth (whatever that may be) and a frequency of VOLTAGE with the digital audio signal...

PCM WILL travel long distances, but NOT if you're using injected power with it

or so I've been told...I'm sure there are several engineers here that can either rebuff or confirm this...but I've been told that digital audio can't be run through powered splitters/combiners/amplifiers like regular cable and video signals can

shoe...

how far down the google list did you go for that?

I made it trough 5 pages before I gave up!

Third search, first page, second item. On the premise that digital audio was a digital transmission unlike analogue video I searched from a s/pdif angle

guys - thanks for your help.

I had the same thought exactly - I've been searching for about two days and didn't see the LA audio product. I'm trying to find a distributor here in the US, and I'll let you know what I find out.

I came across this product as well:

Thanks again,
