Hi all. Well, another week, another 1000 emails behind, and another
project tossed at me at the last minute.

Here's the latest. I've been asked to help with muting a microphone
via footswitch.

Here's the longer story. The microphone in question is balanced and
has an impedance of 1K ohm. While I could do this mechanically that
would result in a loud pop each time the switch changes position. So
I'm thinking perhaps a 4066 CMOS switch to make/break both mic lines
simultaneously. I'm not super concerned about this being really hifi
audio. I am slightly concerned about leaving the audio input
"floating" when the switches are open.

Any thoughts?

Thanks!

Josh
