Echo, it should no big deal really to share sources.

Just make sure you use the digital connections
from DVD/CD players to the main receiver, and
analog connections to the secondary receiver.

On devices that only have analog audio outputs,
be sure to use something like the Tributaries
"buffered Y". Some components you can get away
without using them, but some cause the signal
to be distorted when using regular "Y" connections.

Hope that helps. If you have any more concerns,
let me know,

I have found that when using digital outputs to the main zone and analogue outputs to the secondary zones that there can be timing issues from main to secondary. If there is a possibility of of adjacent rooms sounds being heard in the main room or vice versa, things can sound sort of strange. Of course, if the rooms are isolated there would be no problem.

You will have to forgive my ignorance, but what
is a "video DA" (and where available)?

It's a Video Distribution Amplifier. Think of it as an amplified splitter for video signals. Wait for other to suggest dealers.

You could always use the buffered "Y" approach if that becomes a problem.

And by the way, after we had one bad buffered "Y" and I got curious and opened it, we don't buy them anymore. They are as simple as 2 resistors "Y'ed" together. I believe the value was 1k.

Radio Shack has a A/V da that should fit your needs...

If you want higher end, check out brands like Niles, Kramer Electronics, etc. REal high end get's very expensive.

Matt and Larry:

Thanks very much for the info regarding the video distribution amplifier. I am obviously not a "Custom Installer", but the posts in this forum are extremely helpful for us morons who are trying to string together a functional system on small dollars. Your willingness to take the time to answer basic questions from people like me is greatly appreciated.

Can any of you tell me what amps distort the audio when used in a "Y" configuration? I thought that was a thing of the past!

The first two-zone systems I did used Ys and a customer's 1970s amp. I found that most of those amps did indeed distort the signal when they were off. Their inputs look to signal like a diode in series with a resistor when the amp is off and all the voltages have gone to zero. Turning on the second amp solved the sound in the first zone, which the customer had trouble understanding.

I also have not seen shorting of non-used inputs since those old components. Again, any models come to mind? I'd like to know what to be wary of if any current product has this problem.

A good answer is easier with a clear question giving the make and model of everything.

Anyone ever use any of the Aegis products for multizone A/V? (www.aegishome.com). The AVMS system looks impressive, although I'm guessing it could be pricey. Just wondering.
