Combining digital Coax Signals

[Darkeyce]

I'm so far in over my head on this...
I have two audio sources and one input destination. I think in theory it i think it should be possible to reverse a Y splitter and feed both Digital Coax signals into the single destination resulting in a "merged" sound.

I fear a few things...that i won't get a merged sound but instead a kind of staticy white noice; That the input signals will in some way overload the recieving item; that ther is no standard for the polarity of digital coax outputs and that i'll jsut create a circuit and burn something out.

Would you guys mind giving me some thoughts on expected results as well as a means of accomplishing the underlying goal of getting two sources into one place without having to manually switch them.

thanks

Not in theory and definitely not in practice. Digital signals cannot be combined in the same manner as analogue signals.

No merged sound, just noise. If it is a case of automatically selecting the active feed, the front end, or a simplified version of it, of gmarsh's headphone amp will do. http://www.diyaudio.com/forums/showthread.php?s=&threadid=59357&highlight=
If, OTOH, you want to mix two active feeds then you will need a digital mixer of some sort.

Argh...

Thanks for the clarification...now that you said it and i think about it a bit...merging two digital datastreams doesn't make much sense does it ?


I'll need to find a simple digital mixer to handle the two active sources.

Thanks for the help...I'll resume lurking now.
