TROUBLESHOOTING TIPS
Q. Can I patch the SOLO SL820 after the mixer and
before the power amp?
A. Yes, but only in cases where just eight feedback
filters are needed, such as on the monitors
alone. Eight FBX filters may not always provide
enough gain before feedback for your entire mix.
Q. Sometimes I don't get enough gain before feed-
back. Why?
A. Gain before feedback is determined by the num-
ber of fixed filters you set; increasing the number
of fixed filters during setup increases the system's
gain before feedback. Fixed filters are set
automatically during the initial setup and remain
on the initially detected feedback tone -- they do
not move. You can reconfigure the filters from
the factory default setting (six fixed and two
dynamic) to any combination of fixed and dy-
namic filters. Review the procedure on page 10,
UNDERSTANDING FIXED AND DYNAMIC FIL-
TERS of this operating guide.
Q. The Clip Level LEDs do not light. The unit will not
catch feedback. Why?
A. The unit is not in the signal path. Check the
connections.
Q. Why does one of the Filter Activity LEDs blink?
A. The last filter to be automatically updated blinks.
During normal operation, the blinking will move
from filter to filter as the SOLO finds new feed-
back points. This gives the user a visual confir-
mation that the unit is functioning properly.
RESETTING THE FILTERS: You must reset the
FBX if the microphones or speakers are moved
significantly.
To reset ALL filters: Press and hold the reset
button until the filter LEDs flash about 7 times, or
until all filter LEDs turn off.
To reset only the dynamic filters: Press and hold
the reset button for 3 flashes and let go. The LEDs
that indicate current dynamic filter placement will be
off, and the fixed filter LEDs will remain on.
