Lapel microphones used with radio-mic transmitter body-packs usually require a low-voltage bias that is normally provided by the pack. These useful adapters take the place of the pack, plugging directly into a standard XLR-3 microphone connection. The adapter derives a power supply for the microphone from a mixer or standard phantom power supply, and provides a balanced output.
Several versions are available for commonly-encountered microphones, together with a test-bench “bodge” version, providing spring-terminals for testing unterminated microphones. The bodge version may also be useful for live emergency situations such as unforeseen flat batteries in a transmitter pack.
Please note that the connectorised versions, other than the 20-767 are for use with 2-wire microphones.
