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 benefit from the 
use of a good EQ—like the FBQ800.

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 first 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 flow of audio traffic 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. 

When a specific 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.
