The EMP3L Electret Microphone Power Adapter from Ambient Recording allows hardwired use of a lavalier mic by converting phantom 48V to 5.6V electret power, and outputs an electronically balanced signal with low impedance. This adapter is designed for use with Sennheiser SK 50 and SK 250 microphones, and converts a 3-pin LEMO connector to a standard 3-pin XLR male connector.
