BE CAREFUL! PINK NOISE CAN HURT SPEAKERS AT EXCESSIVE VOLUME. MAKE SURE VOLUME ON PINK NOISE GENERATOR IS DOWN BEFORE TURNING ON.
6)Observe output response
7)Turn off pink noise and
with a piece of music you are familiar with. (NACA disc) Does system sound like it looks? If not, reposition microphone until system response looks like it sounds.
Major | system | problems, | for instance large response “holes” | ||
or “peaks”, | should | be | solved by correcting speaker or | ||
system | problems. | Trying | to equalize out large response | ||
errors | (over | 6 | dB) | will | result in overdriven amplifiers and |

8)Once microphone placement has been verified, recon- nect pink noise.
9)Begin to equalize by first adjusting the frequency posi- tions that need to be effected. Since adjacent bands inter- act with each other, you will need to go back and forth between frequencies to get the best balance
10)Periodically verify curve by listening to your reference music. Equalize one channel at a time. Compare your
“EQ’d” curve with the original response by switching defeat
switch If it isn’t getting better, return to zero and start again.
11)Once one channel is correctly adjusted, the other channel will come easy. Move the microphone to the opposite side, change the pink noise channel, and equalize for the same response.
12)Make any fine tuning adjustments while listening to both
channels simultaneously.
13)Reinstall
SOME SUGGESTIONS:
>It is best to equalize one channel at a time. Trying to set all four channels at once confuses which channel is producing the results.
>If you can identify a response problem by ear, move the microphone to a point that reveals the problem Mike placement can have a very large effect on
