In Reply to: Can a mic just "go bad"? posted by soundnut on July 18, 2009 at 06:29:07:
soundnut,
Microphones are surprisingly delicate items taking diaphragm with a very small surface area- 3/4 to 1" diameter and converting mechanical vibration of sound waves to an electrical signal. For the diaphragm to be responsive, it's as low mass as practical and a suspended membrane. These are so minimialist that it can be damaged by sound pressure alone not to mention being dropped or having gum stuck on it. Looking at adverts for used mics for sale, it it often mentioned "no smoking studio" because even the film of smoke residue can degrade the sound. There is also an amplifier in a microphone- mics with tube amplifiers have become more popular in the last few years- and these tiny amplifiers can be "pooped"- that's the technical term, plus any of a number of wiring connections that may have come under strain.
There are millions that like you that have suffered the heartbreak of bad microphones. I have an inexpensive Shure dynamic from the 60's that, though beautiful in a crude industrial way, absolutely does not work. Still, I've decided to try and forget and get on with my life, focusing on beauty instead of thrift stores.
Say- 3 working microphones for $13 isn't bad!
Cheers,
Bambi B
