Yes, an 1/8th inch stereo male jack will work correctly in the audio
input jack, which works fine for a set of headphones, or one of those
cables that has a stereo 1/8" jack on one end and 2 male RCA stereo
jacks on the other end (like the ones that come with portable cd
players so you can plug them into a stereo?). Is that cable the
"standard stereo patch cord" you're talking about?

like this:

you're suggesting just taking one of those signals, using adaptors
(say from radio shack?) to go from the RCA connector to a 1/4" cable
(like a guitar cable)? would it be ok to run that signal into a mixing
board? would there be any weird impedance or signal strength issues?
