Shure 545S Series 2 Repair

Submitted by buck1112 on Mon, 07/25/2022 - 14:09

Greetings,

I have an older, used, "patent pending," Shure 545S Series 2 (pistol grip) microphone, and I'm gradually fixing it, having first reassembled the switch in the handle section. I do get sound from the mic, but it is a little on the quiet, "hollow," and less low-frequency side. I'm using it as high-impedance.

Repairing a Shure 545?

Submitted by Charles Turner on Wed, 11/30/2016 - 03:35

Greetings-

I recently bought an older Shure 545 (4-pin Amphenol era) on eBay, and while it works, it sounds a bit of the dog with voice: a greatly diminished low end, and reminiscent of talking through a paper towel tube.

Wiring classic Shure 545 unidyne iii 4 pin amphenol to XLR

Can anybody help me with the correct cable wiring for a Shure 545 which has 4 pin amphenol connector (the type which changes impedance by changing the mic cable) very early I believe made in USA before Shure moved production to Mexico.
I bought 2 of these for my son but need to try to sort cables for him

Hey guys was wondering if anyone had access to old Amphenol mc4 f/m plugs, as the one that came with the mic was terrible, it was a real hackjob in terms of soldering, not fixable.

So far all I've found is a place in Britain that sells premade cables, I would just like the part itself so I can make my own cable. It's cheaper!

Hi,

Anyone know where I can buy a mic lead for an old Shure 545 I have. It's a four pin screw type connection.

Thanks

Shure 545SD Unidyne III vs. SM57. What's the difference?

Submitted by lambchop on Thu, 09/18/2008 - 09:18

So; I was talking with a friend of mine and we both professed our ignorance regarding the difference between these two mikes. Does one have a transformer and not the other? Aren't the capsules essentially the same? Was the SM57 simply an upgrade on cosmetics?

It would be interesting if anyone had some insight on this. at least to me, anyways!

One of the Shure 545 (Unidyne III, predecessor and very similar build to SM57) mics I recently acquired has a broken coil-
