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.
