TURBO MODE SETUP
The FBX-SOLO incorporates Turbo Mode setup,
which is indicated by a flashing red Clip LED. This
lightning-quick setup feature cuts the time for FBX
filter initialization to just a few seconds.
NOTE: The SOLO is set in Turbo Mode at the factory
and automatically engages every time you reset
filters. The SOLO automatically returns to normal
program mode when the first dynamic filter is set, or
when you press the front panel Lock Fixed button. All
the filter LEDs will cycle to indicate that Turbo Mode
is about to disengage.
WARNING: Turbo Mode will cause distortion in
your audio program — it is for setup only. You
must follow the setup procedure outlined in the next
section, and do not talk or play program during
Turbo Setup Mode. Otherwise the FBX-SOLO will
clip, and filters may be set improperly. You’ll know
the FBX-SOLO is in Turbo Mode if the red Clip
LED flashes when no other signal level LEDs are
lit. You can manually override Turbo mode if neces-
sary. If you are setting up in a noisy environment and
the SOLO is setting filters on that noise, press the
Lock Fixed button to exit Turbo mode, then press it
again to unlock the fixed filters. Follow the setup
procedure and allow the SOLO to place filters on
feedback. Press Lock Fixed when you are done to
lock those fixed filters.
MOBILE vs. STATIONARY MICROPHONES
One significant advantage offered by the Sabine
family of FBX Feedback Exterminator products is
their ability to adapt to changing acoustical relation-
ships involving sound system components and vari-
ous user applications. One major source of poten-
tial feedback problems arises in situations with
wireless microphones, when the user of the wireless
mic is moving around the stage/auditorium. As a
microphone moves in a sound space, with varying
degrees of proximity to the speakers and varying
acoustic responses, feedback frequencies may shift.
In such a situation, feedback-free mobility may be
more important a concern than maximum system
gain.
One method of setting FBX filters with mobile micro-
phones is to turn a microphone on and walk around
to the various possible microphone locations. At the
