21750 Barrel Adapter

Mic adapter for Earthworks M30 microphone with HM,

DPR and UH400a/TM transmitters.

This polarity reversing adapter may be needed to

correct for asymmetrical current 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 DPR 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

This is an optional adapter for connecting a lavaliere

microphone to the DPR 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 DPR 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.
