RS has cables that can convert a single mono cable into two for input to a
stereo device. Go back and talk to their *experts*, they may be able to help
It's also possible that you have a ground loop that is causing the hum.
Given that you needed so much help with the mono/stereo problem,
trouble-shooting a ground loop problem seems like way more technology than
you can handle. If the stereo/mono cable from RS doesn't fix the problem,
get some outside competent technical audio help to come on-site.
