Not to hijack this thread but I have a related issue. I'm trying to combine the outputs of an iPod/MP3 player into a single mono channel to feed a non-inverting LM3875 chipamp. Would a simple 10K ohm resistor in line with each + input work before summing the channels? I'm looking to do the simplest thing that'll keep me outta trouble.
Something like this...

Does the fact the the chipamp kit is non-inverting have anything to do with anything for summing channels?
Thanks.
