Equalizing the monitors
The AIR System menu offers a two-band shelving type
equalizer. This equalizer can be configured individually
for each monitor, and it is implemented for fine-adjust-
ments of the tonal balance.
For information on navigating to the Calibration sub-
menu and setting parameters, see “Setup menu ►
Monitor calibration” on page 26.
Range ±6 dB
Adjustment step 0.5 dB
Equalizer Band I (Bass) 100 Hz to 1 kHz
Equalizer Band II (Treble) 1 kHz to 5 kHz
Filter type
Shelving
Notes considering equalization
You should be very careful using the equalizer if you
are making adjustments by ear. In a room with good
acoustics, equalization should not be necessary at all.
As a test signal you can use full bandwidth pink noise
(tracks 2 or 13) from the Dynaudio Professional AIR
test tone sets.
In a room that you feel is heavily overdamped at higher
frequencies, you may wish to add some level in the high
end in order to get the right balance.
In a highly reflective room, you may wish to attenuate
the high frequencies.
If you have made a good job placing the monitor in a
proper position you should not have to touch the low
frequency band.
Once you have made adjustments using the equaliz-
er, you should leave the room and come back about
15 minutes later, bringing some music that you know
well. Play this music.
Your first impression at this point
is very important for the assessment of the tonal bal-
ance of the monitor system.
Listening for a long time
will change your perception of timbre. This effect is sim-
ilar to the “white balance” your brain performs for what
you are seeing. After a short time, you are getting used
to a new tonal balance or timbre. What sounds “cool” or
“fat” then is not necessarily sounding right for monitor-
ing purposes.
Please note that additional equalizing can be done us-
ing the AIR Control software. It includes a four-band
parametric EQ that will allow for more precise EQ ad-
justment of each monitor.
