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.
