[MHMLSHURE]

Thanks Scott! I tested the Shure 55 fatboy last night and it actually worked!!!!!! Very pleased. I might not have to do anything at this point but am interested in being able to use an XLR connector so I can press my California Blonde amp into services with it.
When I take the connector apart, I see that it actually has 3 wires, 1, 2, and 3 so I think its balanced but not sure. Its paired with the TS connector for an unbalanced application. I ordered a Hosa MIT - 129 1/4€� TS to XLR3M impedance transformer (connector) so I can use it with my amp that requires an XLR input. Not sure this will work for me. But it works perfectly right now with an old Karaoke platform I had laying around - the platform accepts the TS connector. I have to turn the volume up quite a bit however€¦.

Based on your suggestion, I will NOT be installing the SM-58 capsule in the mike.

Any insights would be greatly appreciated.

Howard

Download the manual from Shure. Make sure you get the right one... I am
assuming from the fact that it came with a TS cable that it was the multi
impedance model. For modern inputs, set the switch to position M.

Take the Amphenol connector off that cable and throw the rest of it away
because it's not useful. Connect a cable with an XLR connector to the
Amphenol connector... you do NOT want to use an unbalanced cable with this
microphone once it's in medum-Z mode. The Amphenol connector is wired
with the same numbering as an XLR... pin 1 is shield, pin 2 hot, pin 3
ground. However, the pins are not in the same positions so look at the
numbers in the plastic block. Solder hot and fast because many of these
are old and crispy.

Putting an SM-58 capsule into one of these really doesn't change the sound
very much... it still sounds terrible even with the 58 capsule in there
because what is wrong with the sound is mostly the grille and body design
creating all kinds of internal resonances. And putting a 58 capsule inside
will substantially devalue it. So if it is working, I would not touch
it... just make up the correct cable so you can use it properly with a
normal balanced line.

If it isn't working, put a 58 capsule in there, sure.
