seeking audio adaptor mini xlr - jack

[tg]

Hi, I'm looking for an adaptor that will connect my Shure lavalier
mike (with mini xlr plug) to a quarter inch jack socket on an m-audio
microtrack.

I've tried studiospares, shure, m-audio, no luck. I'll make an adpator
if I have to but I'd rather buy a ready made one. Thanks for any help.

What's normally on the end of the lead rather than a 1/4" jack ?

You will need a custom-made adapter that will take
the phantom power supplied by the MicroTrack and
convert it to the voltage required by the microphone.
AFAIK, this is not available as a commercial item,
although is it not rocket-surgery.

I don't offhand know which polarity the battery needs to be. I believe
with the Shure mikes they need to have positive power.

Before doing this, first make sure the 1/4" input has enough gain in the
first place to deal with a mike level signal.

You have ~30V available out of the 1/4-inch connectors
on the MT2496. You need to establish exactly what is
the pinout and power requirements for your microphone.

The required circuit is *SOMETHING LIKE* this one...
http://www.uneeda-audio.com/phantom/p48t122.jpg
which converts P48 phantom to 12V. A similar circuit
can be used to produce whatever voltage your mic
wants, and to route the power, signal, gnd, etc. as
needed.

NOTE THAT THE CIRCUIT CITED IS *NOT* EXACTLY
WHAT YOU NEED. Without the exact details of your
mic, a precise answer is not possible. Do you have
the complete model number of the microphone? Do
you have the wiring diagram and/or pinout of the mic
connector?

Is this it?

That would be the right connector if it were male.
(Obvious lesbian joke left to your imagination.

But note that the interface between the OP's microphone and
the 1/4" mic inputs on the MT2496 takes more than a simple
adapter/cable.

That seller doesn't post to the UK unfortunately.

This appears to show the pinout of your microphone and
the wiring of the interface (page 10) .....
http://www.shure.com/stellent/group...ug/documents/web_resource/us_pro_mx1bp_ug.pdf

If I am reading it correctly, your mic wants...

Pin 1 = ground
Pin 2 = power (+6VDC? from a casual glance at the circuit)
Pin 3 = Audio out of mic
Pin 4 = Pin 3 [dunno why?]

You can interface it to the 1/4-inch mic input jacks of the
MT2496 with a variation on Rick Chinn's circuit I cited
previously. You would need to change the zener diode
to limit to 6 volts, and change the wiring where it goes
to the microphone head. It seems unlikely that you could
fit the required components into either connector shell.
