Allows you to connect a lavalier or headworn microphone with a mini-XLR connector directly into a mixer console or mic preamp that is capable of supplying 48V phantom power
Converts the high 48V to lower voltages appropriate for small electret microphones
The mini-XLR jack (3-pin male) accepts most headworn and lav mic mini-XLR plugs and the standard XLR output easily connects to all mixer and preamp input
