Why do I need an equalizer?
If we all lived in a perfect world,
there would be no need for audio
equalization. Sound systems would be
perfect and would reproduce perfect
signals in all their glorious perfection.
Also, everyone in that perfect world
would like the same amount of bass,
midrange and high frequency, and there
would be no such thing as feedback.
But the world isn’t perfect, is it? Even the
best sound system can benet from the
use of a good EQ—like the FBQ800.
How does it work?
Imagine the frequency range of the
sound you hear as a highway, a very
wide one with nine lanes. Each of these
“lanes”represents a single octave
of the sonic spectrum. The rst four
lanes, labeled 63 - 500 (Hz) contain the
really low frequency sound content,
mainly bass, bass vocals, and the kick and
tom drums. The three lanes labeled 1 k,
2 k and 4 k (Hz), make up the fundamental
zone of most musical instruments and the
male and female vocals. 8 k and 16 k
cover the frequency range of cymbals,
snare drums and higher pitched
percussion instruments.
The FBQ800 allows you to control
the ow of audio trac in each of these
nine lanes. When properly applied,
EQ makes it possible to hear all of these
frequency ranges equally, thus the
term equalization.
Feedback elimination
When a specic frequency, or
range of frequencies, reaches too
high a level, feedback occurs— that
all-too-familiar squeal or howl you get
when the mic is too close to the speaker.
Basically, feedback happens when there
is so much of a particular frequency
that it is picked up by the mic and run
through the system again. That’s why
feedback typically gets louder and
louder the longer it’s allowed to occur.
Needless to say, this kind of feedback is
very undesirable.

This is where the FBQ800’s Feedback
Detection System really works its magic.
In this ingenious circuitry, LEDs on the
individual faders light up when that
frequency band is approaching the
danger zone. All you need do is lower the
illuminated slider until the LED blinks out—
voilà, feedback problem solved! What once
required a highly trained ear is now an
activity that even a child can master.
Sonic toolkit…
That really is the best way to describe
the FBQ800. With its nine frequency bands,
you easily ne-tune your sound and instantly
eliminate feedback. And each fader can
be used to boost or cut the frequency
range it controls by as much as 12 dB
(and that’s a lot!).
Special attention is paid to the low
frequency zone. In addition to low frequency
faders, the FBQ800 features a Low Cut lter
for removing unwanted low frequencies
such as oor rumble, room resonance,
electrical hum, etc. This is especially handy
if your system is being used for speech
rather than music.
To boost or to cut, that is
the question
Raising and lowering specic frequency
bands can improve the frequency response
of any room’s acoustics. For instance, if the
room you’re in is“bass-heavy,”lowering the
63 and 125 Hz faders can help eliminate
an overall “boomy” or “muddy” sound.
Likewise, gently boosting the 8 and 16 k
sliders can add sparkle to a somewhat “dark”
mix. Are the vocals getting lost in the mix?
Raising the level of the 1 k slider can help
bring them out.
It’s important to note that raising a
single fader level is not always the best
solution; it’s often better to lower the bands
surrounding the frequency you want to bring
out, and then boost the overall volume level
to achieve better headroom.
Built for accuracy and reliability
Speaking of headroom, FBQ800’s
6-digit LED Input/Output meters and
level control are provided for precise
level maintenance. Long-term reliability
is ensured, thanks to high-quality
illuminated faders and switches,
and our ultra low-noise audio operational
ampliers provide outstanding sonic
performance. In addition, all Mini Series
components may be stacked to create an
ultra-compact signal processing solution.
