[simpits-tech] Common Ground?

[Brian Sikkema]

Hey Guys,

I got those goofy headsets today. They weren't XLR connectors like we 
thought. Matter of fact, each had a different connector, one with holes, one 
with pins, and each with a different layout. Seem to be the same type of 
headsest, though, and I've figured out how to get them working with PC. I do 
have a question, though.

Right now the plan is to use a 1/4" jack for both the mic and headset - I.E. 
only one plug for the whole headset. A 1/4" stereo plug has 3 bands, 
normally used for ground, left channel and right channel. Here is my 
question: Is it possible to have mic and speaker share a common ground? This 
way I would have a 1/4" plug on the headsets, with one band for ground, one 
for speakers, one for mic. Then from the 1/4" jack it would split off into 
the mic and speaker lines to 1/8" plugs that would plug into the computer. 
Here is a rough drawing of what I'm planning to do:

It seems to me it's perfectly doable, but I figured I would check with you 
guys. I figure someone here has probably tried something similar at one 
time, and can tell me if it won't work.

Brian
