Re: Circuit for second PTT that will mute Mic but allow line-in...

John, you mentioned 100mv for the audio signals, is that ballpark for both computer audio and mic audio?  I guess I'd assumed it was around 1 V p-p or line level or somesuch.  But I haven't measured it.  Is +/- 100mv what I can expect for both sources?
