Section Ten: Troubleshooting Tips
In the unlikely event you should experience trouble with the unit, here are some suggestions about
what might be wrong. Some of these are pretty obvious, but so sometimes are the solutions! For
additional assistance, call the Sabine Customer Service Department at (352) 418-2000, Monday
through Friday, 9:30 a.m. to 5:30 p.m. Eastern.
Most likely you are pushing a VERY HOT signal into the box. It’s
hard to make the Graphi-Q clip. Check connections for intermit-
tence, or check downstream from the Graphi-Q. Check the
Graphi-Q output level and turn it up.
ALTERNATIVELY: The
Graphi-Q may still be in Setup Mode
, which automatically
maximizes the Clip Level until the first dynamic FBX filter is set.
You may exit Setup Mode in several ways (see
Sections
6.4.2.2
&
8.2.5.1
).
LITTLE OR NO AUDIO COMING
FROM GRAPH-Q OUTPUT
Check Graphi-Q compressor settings. See
Section 9.5.
Check filter availability. Make sure unit is not in BYPASS.
See
Sections 6.4
&
8.2.5
. If you have the Graphi-Q patched in an
effects or auxiliary loop, you will only catch the feedback in the
effects loop, and not the mixer input channel. Or, you may have
used up all the available FBX filters, leaving no additional filters for
new feedback frequencies.
PROBLEM
SUGGESTION
Check connections. Make sure they are line level. Are input
and output reversed? Are the Graphi-Q2 LEDs showing signal?
If no, make sure the unit is not in BYPASS mode, and that audio
signal is feeding Graphi-Q2 input. If yes, check connections and
gain downstream from Graphi-Q2.
Try using the graphic equalizer to “flatten” the room. There may
be a big frequency “bump” in a room with less than ideal
acoustics; this is better treated with a wider filter.
Check Graphi-Q delay settings.
Read this manual carefully; there’s a lot to understand. Make
sure you are raising the gain in the correct channel! Make sure
your system is set up and audio is passing through.
