CONGRATULATIONS! You now have the state-of-the-art in feedback control. The Sabine
FBX-SOLO gives you automatic real-time feedback control for any channel on your mix,
makes your system louder, and increases the clarity of your mains and monitors. It includes
a user-selectable noise gate, especially useful in systems with a number of open micro-
phones, such as courtrooms or conference rooms.
The FBX-SOLO
incorporates the latest in design and digital signal processing technology.
It automatically senses feedback in a sound system and determines its pitch. It then places
one of its six micro-filters on the resonating frequency and eliminates the feedback in
typically less than one second.
Before the invention of the FBX, the most common device for controlling feedback was the
31-band graphic EQ. However, the FBX has three distinct advantages. The most obvious
is the FBX functions automatically, even during the program. Another is the FBX micro-
filters are precisely placed while EQ filters are fixed. The difference: FBX filters do not have
to be as deep, so there is more system gain. The most important advantage is that FBX
micro-filters are ten times narrower than 31-band EQ filters. FBX micro-filters return up to
90 percent of the power removed by EQ filters.
Over the years, engineers stopped using 12-band EQs in favor of the narrower-filter 31-
band EQ for controlling feedback. The FBX represents the next step. An EQ would need
more than 10,000 sliders to be equivalent to your FBX. With the SOLO, your monitors will
finally sound loud enough, everyone in the audience will understand each word, and the
mains will sound natural and transparent.
