We assume that if you've gotten this far, you have a general idea of how the controls of a parametric equalizer work, but as a
quick review:
The Gain control determines how much the specified frequency range is amplified or attenuated, expressed in decibels.
The Bandwidth control determines how wide or narrow a range of frequencies will be affected, measured in octaves.
The Center Frequency control determines what frequency will lie in the middle of the adjustment curve, expressed in Hz.
You will be able to identify where your speakers start to roll off in terms of frequency response (especially on the low end)
pretty quickly. You can't overcome pure physics with an equalizer, and small speakers will never reproduce bass with the same
authority as larger ones, so there's no point in trying to give a 15dB boost at 30Hz to small monitors in the hopes that you'll get
the equivalent of a free subwoofer. (What's frequently more effective with bass-shy speakers is taming the often over-boosted
mid-bass that manufacturers dial in in the hopes that you think you have more low end than you do).
As you study the RTA, we recommend identifying and correcting any glaring peaks or valleys over a relatively narrow ranges of
frequencies first to take care of any "hot spots." Then, work your way out to making broader changes to the overall curve.

Chasing Your Tail

Speaker calibration can be a frustrating process, especially if this is your first go-around with it. Sometimes it's like squeezing a
balloon: When you squish one end, the other end puffs out. So it goes with calibration. Make a boost to one frequency, and the
surrounding frequencies go up, too.
Experimenting with the center frequency and bandwidth controls will help, as will a good dose of patience and allotting
enough time to do it up right. Your efforts will be rewarded when you play music through your calibrated setup for the first time
and wonder if someone swapped out your tired old monitors with something new and much more expensive!

Saving Your Calibration Settings

You can save your calibration settings in the form of a preset by going to the Save Preset menu and typing in a friendly name for
your file, preferably one that uniquely identifies the speakers and location ("JBL 4312 FM Air").

Tweaking After Calibration

You may notice that while your speakers sound significantly better than they did before you calibrated them, and they are
technically much more accurate, they sound a little thin in the low end and a little dull in the highs because of the way the
human ear perceives sound at the far ends of our hearing range.
We suggest that instead of making changes to the EQ sections, you use Omnia.9's Loudness 1 and Loudness 2 menus to make
subjective adjustments. These menus each give you three additional bands of fully parametric equalization.
If desired, they also allow you to adjust at what point on the Speaker Volume control the changes take affect (since our ears are
less sensitive to certain frequencies at lower volume levels).
The Minimum slider on each EQ band sets the point on the volume control where the EQ has no effect on the sound.
The Maximum slider sets the point on the volume control where the EQ in that band is in full effect (boosted or cut to
whatever gain level you have set).
For example, if the Minimum slider is set to -20dB, the Maximum is set to -10dB, and the Gain is set to minus 5.0dB,
equalization will begin to take effect when the volume control is set to -20dB and will be attenuated by 5dB by the time the
control is set to -10dB.
If the minimum and maximum values are the same, the loudness controls function as a normal parametric equalizer
independent of the volume setting.
