TR50SQ doesn't work

[Gregory Lee]

I received the Tram TR50 lavalier mic in the mail today and for some
reason it does not work with my Sony UWP-C1. This version has a 1/8
inch (3.5mm) miniplug and the specs say that phantom power is provided
by the transmitter. I have no idea why it is not working since, I
assumed all transmitters provide phantom power. The mic that came
with the UWP-C1 system does work, and the lavalier does not use
batteries.
Does anyone else own the Sony UWP-C1 system and could let me know if
the transmitter provides phantom power, and if the mic that comes with
it is dynamic or eletret condenser?

If my transmitter can't provide phantom power, then I'm limited to
only dynamic lavaliers, and all those great mics out there aren't
usable. Or perhaps by chance the TR50 I have is faulty?

YOU CANNOT PUT PHANTOM POWER ON A MINIPLUG.
If it is NOT 48V differential, it is NOT phantom.

Find out what power it really wants. Then get out a meter and find out
what the Sony is putting out.

The meter will tell you all you need to know. If there is DC resistance
across the pins, it's a dynamic. If there is DC voltage provided by the
pack, it's an electret. Get a TRS plug and measure what is between T and
S and between R and S.

Do you have the service manual for this?

Sony will not tell you this stuff. Sony consumer basically doesn't have
anyone who talks to customers who has a clue. You need to find out what
the pinout of the connector is, what power it provides, and what resistance
it provides it through so you can order the right microphone.

This stuff is NOT standardized. This is why microphones need to be made
up custom for each sort of body pack. Like I told you several weeks ago
when you started with this crap and I told you to go to Countryman and
have them make you one.
