If you plug a mono plug in a stereo jack, the 2nd channel will be tied 

to the ground 'sleeve' of the plug. It probably won't hurt the intercom 

(it probably has series resistors in its outputs to protect against just 

this issue) but it sure ain't gonna help.



There are several possible 'workarounds'. The simplest (which will lose 

the right channel from the intercom) is to wire a stereo plug (tip & 

sleeve only) to a mono inline jack. Leave the ring terminal of the 

stereo plug unconnected. Use this adapter between the headset plug & 

your intercom jack.

There is an even simpler, but not foolproof, workaround.  Insert the mono 

plug only to the first detent, not all the way in.  It will stick out about 

3/16 inch.  This connects both sides of the mono headset to one stereo 

channel.  Be careful to not accidentally push the plug in all the way.
