Does anyone have the Audio Technica AT853rx hanging choir mics? Last night, after about a year of having them (duh), I noticed a small switch on the connector. It looks like a switch between when you use the wire hanger (a diagram of an angled thingy) and when you don't (the thingy is a straight line). I see nothing about the switch in the manual. Does anyone know how this affects things? Also, wasn't this mic very popular? Why was it discontinued?
