I just ran a theatre show from my computer for the first time (see previous
"multiplay" message) and ran into the issue that the head phone jack was
stereo and the input jack was mono ... ( you can tell by the number of lines
on the insert pug (stereo inserts have two black lines and mono inserts have
one)) ...took me a while to figure out why I my sound levels kept getting
messed up so I thought I would pass it on.

     There are a number of possible solutions for this
         1) employ a splitter and have two mono inputs to your amplifier
                      ( I ended up using an external USB sound card with two
1/4 inch outputs)
         2) make sure your (mini) 1/8inch to 1/4inch adapter is also is a
stereo to mono adapter
         3) change the output of your computer to mono
