** I got that.
But the idea is based on a fallacy.
Some like to remove the internal step-up transformer from an SM57, making the impedance 20ohm - which eliminates all trace of pre-amp circuit "damping" and proclaim it then sounds so much better.
Sensible folk use their SM57s and SM58s just as Shure advise.

I think he also wants to protect the membrane. :)

o be able to compress it, and to possibly damp its diaphragm's motion when the broad screams into it on karaoke night.
ong enough, this is new design. And if there is a better such device out th ere, I figure this is the place to ask.
can. Look, take a nice 15" woofer on the bench and push on the cone. Now sh ort across the terminals with a nice stout wire or whatever and push on it again. Feel the same ? NOPE.
it has been done somewhere. But if you cannot find it, do it and be findab le. If they come and sue on patents, make sure you got something to sue for .
and people sitting there saying "30 people calling in can't be all wrong" a nd shit like that. Know what ? I think there are mad scientists working out in heated/airconditioned barns all the time figuring out new shit, but do not want to give it to the world yet.
t to try it anyway, and this is only part of the whole thing.
UL ! LOL.
e past. What is out there that can do that ?
I like the optical limiters that use LEDS -- UREI LA4 was widely used. A cl assic.
The SM57 isn't half bad for vocals, either!

sed for live sound and there are many imitators.
ncies that at higher ones and so there is a physical limit which sets the m aximum SPL that can be handled cleanly. There is also a small transformer i nside that overloads due to core saturation a little above this level.
PL in the mid range. 180dB SPL is impossible as air itself becomes non-line ar and distorts heavily at such levels.
many ways to skin a cat,
afaik the internals are identical. The 58 with a pop filter for vocals. The 57 smaller grille made for instruments

SPDT should do the job nicely.

** The SM57 and SM58 capsules have different "resonator caps" - the close fitting, black plastic cover over the diaphragm. These greatly affect the response of the mics at high frequencies and are responsible for the differing published curves.
Otherwise they are damn near the same with 20ohm coils and a 1:4 step up autotransformer in the handle.
Oddly for a mics described as "Studio Model" there is no hum bucking coil or magnetic shielding on the tranny so they are sensitive to nearby hum fields.

** Shure have a really neat way of implementing an on-off switch. They use a tiny reed relay inside activated by a magnet operated by a slide on the handle. The reed relay simple shorts the capsule wires.
Totally reliable and moisture/corrosion proof.
The slide can be locked in the off position too.
The SM58S has one:

My first electric toothbrush (a Philips) had a switch that worked the same way. It seemed a sensible approach to implementing a switch in a wet environment. Indeed, a specified feature was that one could remove the slider that contained the magnet, and reattach it the other way around, so as to guarantee that the thing wouldn't turn on in luggage.
Later models reverted to a plastic covered push-button.
