[AG-TECH] Mute switch for AG.

[Ed Ritenour]

Hey all

It is my understanding that there is a correct and incorrect way to wire 
the microphones for muting to work properly. When wired incorrectly the 
microphones can be muted but retrain and cause a echo when activated. 
Ours do this, but to correct requires a different cable be strung to 
each mic. I believe the wiring method is defendant on how the mic's were 
ordered. It is my understanding that Gentner web site shows the correct 
wiring method to prevent the echo.
