Lectrosonics 21750 Polarity-Reversing XLR Barrel Adapter for Earthworks M30 with HM or UH400a/TM

The Lectrosonics 21750 is a top - notch polarity - reversing XLR barrel adapter. It's designed for Earthworks M30 microphones that come with HM or UH400a/TM. This adapter reverses the polarity (swapping pin 2 and 3), which can be crucial for fixing asymmetrical current draw in many P48 - powered condenser microphones. That includes older Neumann 100 Series and Rode NTG3 mics. If your mic doesn't power on properly when used with a UH400 - or HM - transmitter, just insert this adapter between the transmitter and the microphone.

Using the Lectrosonics 21750 adapter is easy. First, make sure your Earthworks M30 with HM or UH400a/TM and the transmitter are turned off. Then, simply insert the adapter between the transmitter and the microphone. Turn on your equipment and check if the microphone powers on correctly. When it comes to maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or humidity. If you notice any damage, stop using it immediately and contact customer service. And remember, this adapter is mainly for fixing power - on issues related to polarity and current draw in specific microphones.
