Q. Why does my SOLO set filters when music is
played through it?
A. Make sure the FBX’s Turbo Mode has been
turned off before you program. Check the signal
level ladder. If the red Clip LED lights with no
other signal level LEDs lit, the FBX-SOLO is still
in Turbo Mode. Turbo Mode turns off automati-
cally after the first dynamic filter is set, or you can
turn it off manually by pressing the Lock Fixed
button. Turbo Mode sets filters very quickly —
without analyzing the signal — and may not
distinguish feedback from music or audio signal.
Q. Why would the FBX cause a noticeable hum?
A. It may hum if the system is improperly grounded.
Check for bad grounds.
Q. Why does my system sound thin and muffled?
A. Place the SOLO in Bypass Mode. If the system
still sounds thin, your problem is probably with
improper use of a graphic EQ. If the problem
exists only with the SOLO in Active mode, verify
the clip level setting, reinitialize the system and
lock the fixed filters.
Q. With the SL820 in the insert point, I hear no
audio. Why?
A. Your insert point may be wired opposite to the
SOLO. Try reversing the tip and ring (in and out)
of your Y-cord. If you are using a single TRS
cable, you will have to reconfigure one end of it
to conform to your mixer insert point.
Q. Will the SOLO eliminate feedback in both mains
and monitors?
A. Yes, but for maximum gain you should set as
many fixed filters as possible on the system with
the most feedback problems. Choose which
system is more likely to have feedback, and
follow the system initializing procedure for either
mains or monitors. During program, the dy-
namic filters will control feedback for both mains
and monitors if they are in use, but only on the
input channel the SOLO is patched into.
Q. The channel I have the SOLO in seems noisy.
What can I do?
A. If the noise floor is too high, you need to readjust
the gain structure of that channel. Follow the
SOLO initialization instructions in this guide.
