Two sound cards,one digital speaker system

[Bryce]

I have two computers with sound cards and would like to connect both of them
to one set of digital speakers that has only one input.Right now I connect
one output to the other sound boards input,which works fine if both
computers are on.But would rather connect both directly to the speaker
system.What do I need,can anyone help.They won't work with just a simple Y
setup.Thanks in advance for your help.

They don't work in a Y configuration because both streams have
separate queue points. You would need to pump both into a decoder,
and have only one set come out that carried both sounds added
together.

One thing you could do is pump one digital signal into one of the
sound cards, and monitor both that sound card's sounds, and the
digital channel. The digital output of that sound card should have
both signals in its single digital output at that point.

It would be much easier, cheaper, and more practical to spend the few
dollars and have a separate set of speakers for each machine, that is if you
want to do it right.

Self powered digital speakers are not cheap.

Aside from that, it is not an answer to this particular query at
all. He want the two sets of channels in, and two channels out, not
four.

Use two centre tapped transformers, one for left and one for right and
connect the single output coils to the powered speakers, and each PC to each
side of the centre tapped input windings. Use the centre taps as the common
earth.

Either pc will work normally regardless of the other being on or off. If
both pc's are driving the system together you will get both subtracted from
each other as the phases are different.

If you are able to wind your own transformers you could make them with three
windings, or you could make a multiple op amp circuit.

This is for using sound cards with analog outputs, but I think this is the
system you have?

Hope this helps,
Peter

A simple opamp based virtual ground mixer with line input levels
should do ya...look on google for audio mixer projects, lots of stuff
out there :&gt

Dumbshit! READ THE POST FIRST. The signals are DIGITAL!

Man, you usenet casual twits are retarded!

Wrong application, retard boy!

Yer an idiot.

Try READING the original post, crackhead!

Hope this helps

Hope you learn to READ.

The only thing worse than an utter retard that doesn't know how to

read a post before he responds, is a retard that announces his filter
additions. as if anybody even gives a shit. You are that retard.
