Re: [PLUG] Re: OT: multiplexing speakers = solved, more or less

If you look for schematics of simple mixers, you will find that at the most basic level, you can just put resistors on each line before they are combined. You don't need variable resistors for volume control, so you can just use the fixed-value resistors. I guess a capacitor would also make
sense to prevent any DC from passing from one card to another.
Just get a box, pop in some jacks, solder in some resistors (and capacitors), and tie it all together with some wire.
Are the electronics types here giving that the thumbs-up or thumbs-down? heh
I think the only
things to worry about are the component values and how many channels you can combine. (That and everything blowing up.)

Thanks for all the great suggestions! The sound
mixer is basically what
I was thinking of, and I should have known that. I spent a few minutes
looking around the 'Net but didn't see anything likely. I seem to
recall Radio Shack had a relatively inexpensive, very small 2-3 channel
mixer 15 or 20 years ago, but
it doesn't seem like they have it anymore.
For now, I'm going with the quick & dirty solution of running 3 25'
extension cords out to my desk. One will be dedicated, the other two
I'll just switch back and forth by manually plugging/unplugging for
now.
I don't expect that to happen too often anyway, but it it gets tedious
I'll just build a switch box; I may have already have all the parts for
that. Or I might run across a <$25 mixer? Doubtful, I guess.
The sound "chain" idea was
great. I'd never have thought of that. Two
out of three of the devices seem to have line-in, so it might work. I
may try it if I get some free time to play.
And as far as http://en.wikipedia.org/wiki/Superposition_principle goes,
not on a Monday! That just made my head hurt. :-)
Anyway, thanks!
JP

Microsoft has single-handedly nullified Moore's Law.
Innate design flaws of Windows make a personal firewall, anti-virus
and anti-malware software
mandatory. The resulting software arms race
has effectively flattened Moore's Law on hardware running Windows.
