			Tested with Peltor MT7 microphone which needs the adapter circuit.

	You must use a dynamic-to-electret microphone adapter circuit with a dynamic microphone. A quick Google search reveals that the Peltor MT7, MT73, and MT14 microphones require an adapter board. The Peltor MT53 is an electret microphone by default, so it won't need the adapter circuit.		You must use a dynamic-to-electret microphone adapter circuit with a dynamic microphone.
