P/N 21750 Barrel Adapter
Mic adapter for Earthworks M30 micro-
phone with HM, HMa and UH400a/TM
transmitters.
This polarity reversing adapter may be
needed to correct for asymmetrical cur-
rent draw in some P48 powered condenser
microphones, including older Neumann
100 Series, Rode NTG3 and others. If your
microphone does not power on correctly
when used with these transmitters, insert
the adapter between the transmitter and
microphone.
MCA-M30 Barrel Adapter
This adapter may be needed if you are experiencing
noise or distortion with measurement microphones,
particularly the Earthworks M30. The adapter has a
common mode choke for suppressing RF noise. If your
microphone signal exhibits the problems listed above
when connected to a UH400, HM or HMa transmitter,
insert the adapter between the microphone and the
transmitter.
Insert the adapter between the transmitter and micro-
phone to alleviate the problems listed above.

PHTRAN3
Replacement leather pouch with clear plastic screen
cover, rotating belt clip and snap closure. Included with
transmitter at purchase.
MCA5X
Optional adapter for connecting a lavaliere microphone
to the HMa or HM transmitters. TA5M to XLR3-M
connectors. Passes transmitter phantom power
to bias the electret lavaliere microphone. Includes
zener protection to limit bias voltage to protect the
microphone if transmitter phantom power is set too
high.
MCA-TPOWER
This cable adapter is to be used with the UH200D,
UH400, HM and HMa plug-on transmitters with
T-powered microphones. It will protect a T-power
mic against the 48V phantom power setting in the
transmitter while allowing normal operation. The
transmitter should be set to the 15V position for best
operation and minimum battery drain.
