microphone does not power on correctly when used
with these transmitters, insert the adapter between the
transmitter and microphone.

noise or distortion with measurement microphones,
particularly the Earthworks M30. The adapter has
common mode checks for suppressing RF noise. If
your microphone signal exhibits the problems listed
above when connected to a UH400, HM or HMa trans-
mitter, insert the adapter between the microphone and
the transmitter.
Insert the adapter between the transmitter and micro-
phone to alleviate the problems listed above.
