Typical Set-Up
NADY AUDIO graphic equalizers may be used wherever modifi-
cation of the frequency contour of a sound system is needed. A 
graphic equalizer is a solution to any number of sound problems 
or creative urges. 
SOUND REINFORCEMENT APPLICATIONS 
By routing the signal from the mixer to the main power amplifiers 
(or crossover), the overall frequency of the mix may be altered to 
do a number of things. 
Through the use of a real-time audio spectrum analyzer, a 
calibrated microphone, and a pink noise source, the audio 
system may be “TUNED” to make the overall audio spectrum 
response of the audio reinforcement system and the room 
environment atter in its frequency response. 
By turning up the audio reinforcement system to the 
feedback point, then attenuating the oscillating frequency 
(1/3 octave resolution), then turning the system up to 
attenuate the 2nd oscillating frequency, and then the 3rd, 
and so on, you can enable the entire audio system to have 
much more gain before feedback. 
Ampliers and speakers may be protected by the use of 
the LOW CUT feature of the equalizer. Wind noise or the 
loud percussive sound of dropped microphones, etc., could 
potentially cause damage to the amps and/or speakers. By 
rolling off the extreme LOW frequencies with the LOW CUT 
lter, a measure of protection is added to the system without 
severely affecting the overall sound quality. 
In noisy environments, the audio signal may be tailored for 
better intelligibility and penetration. This is especially useful 
for public address systems. 
Creative use of the equalizer allows shaping of the signal for 
a more pleasing sound or for special effects. The only limits 
are those of taste and imagination. 
MUSICAL INSTRUMENT APPLICATIONS 
Putting an equalizer in line with a musical instrument allows 
you to modify the sound of the instrument. You can brighten 
the sound, or add body to a thin sounding instrument, or 
even give the sound a totally different character. 
An equalizer will allow you to eliminate unwanted sounds, 
like a 60-cycle HUM from a badly grounded amplier.

engineer’s bag. NADY AUDIO equalizers offer the features and 
flexibility to perform where it counts in the studio. 
Fix a track that doesn’t sound quite right. Put the equalizer in 
an effects send and return it to the MIX bus. 
Create an articial stereo by splitting a monaural signal and 
equalizing the split signals differently, then panning one 
equalized signal to the right and the other signal to the left. 
Shape the sound by changing the frequency response of the 
track. 
Special effects, like a telephone sound, can be created by 
cutting off the LOW end to 200Hz and the HIGH end to 
6KHz.
