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 (386) 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.
