8) Move to the next peak or dip, and repeat the process until you run

out of frequencies to adjust. Try to remove the peaks before filling the

dips. Periodically, while you are making adjustments, compare the new

curve you are making to the system in an unequalized state by using

the defeat switch on the front face plate of the

PAR-245

9) Play your favorite music. If the sound isn't what you're looking for,

go back to the pink noise and smoothly adjust your curve for more

bass, less midrange or whatever you think will correct the sound.

Remember that this is your system - don't let someone else tell you

how it should sound! When the sound is close to what you want, move

to step 10.

10) Play several different music tracks. If you hear an instrument, voice,

or other sound that is too loud, find the sound on the chart on page 14.

This will give you clues as to what frequencies need to be adjusted on

the

PAR-245

. (If you have already tuned using an RTA, this step is

icing on the cake.) Make one adjustment at a time, giving yourself

time to notice the changes.

11) If you are using another equalizer, like the

DEQ-230

or the

PMQ-210

, as well as the

PAR-245

, you should first tune the system

using the other equalizer. This leaves the

PAR-245

free to make wider

frequency adjustments, compensating for equalization differences

between Radio, Cassette, Video and Digital sources, like DAT and

CD. Select Frequency/Q combinations for each band near the center

of the frequency range, with a low Q.
