There's a set of slides I put together a couple months ago that lay out a
setup & testing procedure. At some point these'll be put together
into an AGDP document ...<br>
<br>
The basic sequence is this:<br>
<br>
Install hardware.<br>
Perform basic Gentner setup (coarse level setting, set up presets per

Set Gentner mic levels<br>
Set output / speaker volume levels.<br>
Test with rat and reflector<br>
Test on-grid.<br>
<br>
If you make it all the way through the calibration & setup steps, you
should have little problem with actual AG use.<br>

Regarding the problem you mention: Do you see levels in rat for incoming
audio? If you bring up rat's Options window, go to Audio, and turn on the
test tone, do you hear a tone? If not, check the Gentner level meter for
the input the PC/MM100 output is connected to. If there's no level there,
you probably have a cabling problem. If there is, check the routing and
the cabling path to your speakers.<br>
