as resoharp suggested above though, maybe a male xlr to female 1/4"transformer package is simplest.

i'll tell you why i don't care for the amphenol type screw on connectors: i've had a couple of mics with them and if you change the cable very often, say from one mic to another, or even with normal usage, the wire where it runs into the connector has always managed to break off, sometimes at the worst possible time! and there's no quick fix on stage. i currently use either an xlr with impedance adapter- shure 545s- a hard wired bullet- shure 707a- or a crystal with a female jack to accept a guitar cord. true, the female 1/4" in a mic itself is subject to be pulled out, and this happened to me once when opening for a big name- but once it happens it teaches a person to be more careful for sure!

But you will always get better and optimal output by using an impedance matching transformer. To run a low Z mic into a high-Z input you have to use the 1/4" connector's shield/ground for one of the signal connections, so you can run into hum problems. Low impedance mics are usually cabled for "balanced" operation where the shield is ground ONLY and doesn't carry the signal, which travels on 2 wires inside the cable, connected to pins 2 and 3 of the XLR connector. Can't connect these to a 1/4" mono connector without losing one side of the signal or ground. But wait, there's more! Low-impedance volume controls, like the ones I make, or the one that comes in an Audix Fireball, will be completely neutered if you plug straight into a high Z input.

It is technically wrong. If you play a low Z mic into a guitar amp you should use an impedance matching transformer!

With all that said, I worked on a similar mic (M23) and if my memory is correct it was High-Z. They were used inside of military tanks. They are nice and small. I even have a pic of that job (conversion to screw-on connector) on my web site:

I'm just saying either a high or low Z mic works with a high Z input. Only matters whether there's sufficient signal voltage. A transformer boosting the low Z to higher Z increases the signal voltage, though. And will likely introduce some of its own tonal coloration.

I have 2 of them from a lot of 30 I purchased back then. This guy called me up after seeing one of my videos on youtube using one of these EV mics. he bought a big pile of them at a government auction.
Anyway, as for the connector issue, One of the best and easiest ways to go is to get a male XLR to female 1/4 inch jack (guitar cord) transformer. from Hosa (they are the orange packages found in most music stores.) it costs about 10 bucks.
this way, if you or someone accidentlly steps on your cord it will simply pull out of the jack with no harm done.
If you can't find the Hosa jack, drop me a line because I can get them through my website.
Enjoy the mic. I like mine a lot. and it has stood up to lots of gigs. It has a cleaner sound than my green bullet or JT30.
