[CQ-Contest] Heil Headset

[Joe]

I have a Heil "Proset" headset with the phase switch.

It does indeed make a difference.

I know it has a stereo jack, but does anyone actually have a schematic 
for this thing?  I contacted Heil but never got an answer.

What is actually happening inside this thing? And can you run separate 
audios like from two rigs into seperate ears if the switch is in one 
mode or the other?
