[AG-TECH] Gentner Echo Cancellation

[Robert Olson]

You need to first ensure that the audio machine isn't set for hardware 
loopback (unfortunately the way to check this is sound-card dependent to 
some extent). One thing you can do is look at the PC input and output level 
meters on the Gentner, and talk into a mic. You should see level on the 
Gentner output to the PC, but not on the input from the PC.

Also check to be sure the echo cancellation checkbox is enabled on each 
microphone. And of course, make sure that you aren't mixing multiple 
microphones into gentner mic inputs.
