Default How to combine two stereo inputs into one output?

I have a pair of self-powered Alesis 520 speakers and I want to
connect both my xbox 360 and my computer to it. What's the best way to
do that? I tried using a $6 audio splitter, but it didn't work out too
well because the sound signals from my pc & xbox were both weakened by
that type of connection. Do I have to buy a mixer or can I use
something cheaper? I want to get good sound and I want something that
will allow both the pc & xbox 360 sound signals to come through at
full strength but I'd prefer to use something that I don't have to
switch on and off or that requires electrical power. I'd prefer to
have it be something automatic and passive, similar to an audio
splitter but without its signal loss problem. I think I read there's a
decent mixer for around $70. I guess I'll buy that if I have to. I may
also buy a subwoofer to add to my system, which would complicate
things even more. I guess I'll have to have a mixer if I get the
subwoofer, right? I used to use Klipsch Promedia 2.1 speakers but I
wanted to upgrade to something bigger, so I got the Alesis 520 studio
monitors. I can't use a receiver since these speakers are self
powered.


You can get a switchbox to allow you to switch from one to the other.
Or you can make a summing cable... imagine a Y cable, with 1K ohm
resistors on each output so that the two outputs aren't directly tied
together.

With the summing cable you will lose some level. That's fine, you have
plenty of extra gain available, so just turn the volume up a bit.
