Would you be going into the auxillary input on the stereo amplifier?

Maybe it's been mentioned, but "y"ing two sources together is not a good idea. There must be a way of at least partly isolating them from each other. Output devices don't take to kindly to being slammed into by another source. There was a great article posted by Masque Sound about that a while back but I can't seem to find it...

NO! I can't play the source from the computer, okay?

I would be going into either tape, aux or phono, depending on the gain I need.

just build a device with a dpdt for each channel and switch sources by applying power to the relays?
Diodes like that on the input stage would be bad with a ~.6V bias you would only get the peaks of the signal or more likely no signal.....

I'm not trying to switch sources, I'm trying to listen to two at the same time, and be able to controll the volume. Please read before you talk.

This should do the trick. The 10K resistors pad the headphone level and isolate the two sources. The dual-gang pots will allow you to adjust each source. The headphone signal levels are plenty high enough to drive the aux inputs even after 1/2 voltage division with the R's and Pot's.

I've used this circuit many times to feed a tape or CD headphone output to an audio amplifier. Keep the volume on the headphone source fairly low to prevent distortion.

Happy mixing!

After a long day of dealing with some really bratty kids, it's hard to be positive.

Thank you to those who have given advice, I think I will go with what Brion suggested...
