How to make a producer's TB mic?

Archived from groups: rec.audio.tech (More info?)

We want a microphone with an on/off button for the producer who sits at
the desk behind the engineer. Just a simple push-to-talk.

What we have, though, is pretty noisy and pops the cans. It's just a
button that opens/closes pin2.

My electronics is a little rusty, but I'm handy with a soldering iron.

Any suggestions where I can find the "right" way to do this? (Or better
yet, just tell me?)

Much thanks,

If it is a real floating mic/cable, etc. shorting pin 2 to pin 1 (ground)
will not only NOT likely turn the audio on or off, but may introduce
ground noise.

Traditional way of muting conventional balanced mics is to short the
signal by connecting pins 2 and 3 together. As the patent drug biz
would say "safe and effective".

Use a normally closed switch, so it shorts pin 2 to pin 3. Push the button,
the switch opens and the signal goes through. With most dynamic mics and
mic preamps this will not pop.
