Hmmm - the Mic plug on the Elecraft ProSet-K2 is mono. There is not 'Stereo' warning below the mic socket on the reap panel.
Didn't I read that the socket was designed this way, so that a mono plug can be plugged in safely? I assume if you plug in a mono plug, the unconnected 'ring' connection on the socket just mated with the sleeve too. ProSet works just great on rear socket.

"Why," said the jackdaw, "my master has a whole chestfull, and makes no more use of them that I do." -Jonathan Swift, satirist (1667-1745) _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
