When using the front mic connector, you must make sure that the shield of the cable is connected to the shield of the 8-pin Foster connector to mitigate RFI.

Even though this is a balanced input it will work just fine with and unbalanced microphone provided that the "mike boost" is checked in the menu. I have used an inexpensive Radio Shack mike with a long cable with a standard 1/4" plug into the rear input with satisfactory results. Currently using a Heil GM5 (unbalanced) with PTT switch wired with a 1/4" plug for the mike connections and the PTT conductors terminating with a male RCA to the PTT RCA on the back panel. Works fine. Routinely receive unsolicited commentary audio reports.
