Unidyne III 545 - Wrong cable or broken?

[milet22]

After reading through posts here on mics, I decided to give a Unidyne III 545 (no switch) a try and compare it to my SM57.

The mic has a 4 pin connector (which I've since learned is an Amphenol MC4F). However, the mic came with a cable that has a matching 4 pin connector on one end and what appears to be a 1/4" TRS on the other end and says "Switchcraft."

I tried plugging in the 1/4" to a preamp, and I don't hear anything on when the preamp input setting is 'low-impedence/mic'. When preamp input is instead 'high-impedence/inst' setting, I can hear sound when I tap the side of the mic, but no sound when I speak into it.

So here's my questions:
1) Does it seem like I bought a broken mic, or is it that I don't have the right cable/connector?

2) If it's a cable issue, how do I go about getting the right connectors? I've seen some posts about soldering the necessary 4 pin-XLR cable, but I'm not sure exactly what I need. I would like to use this as a lo-Z mic ultimately.

Thanks for your help...I don't mind building/making a cable, but I definitely don't want a broken mic.
