Calibrating the
main monitors
Calibration is required to ensure that all monitors pro-
duce the same sound pressure level in the listening po-
sition when fed with the same signal.
The level of the input signal can be locked to a specific
sound pressure produced by the monitors.
Inter-channel calibration
►
Navigate to the Calibration submenu as described
under “Setup menu ► Monitor calibration” on page
26.
►
Select the “Master L Front” monitor.
►
Select the “Calib” (Calibration level) parameter and
press ENTER.
►
Set Calib to 0.0 dB.
►
Play tracks 11/23 (two channel stereo) or track 11
(multi channel DTS) from the Dynaudio Profession-
al AIR test tone sets. These tracks contain filtered
Pink Noise (500 Hz to 2 kHz).
►
Continue to the next channel and set “Calib” to
the same level as the first monitor. If you are using
a multichannel setup, continue to the remaining
monitors.
Acoustic level calibration
In some parts of the audio industry, the monitoring sys-
tem has to be related to absolute acoustic levels.
In the Dynaudio Professional AIR test tone sets, the
tracks mentioned above are recorded at -20 dBFS. This
level correspond to different acoustic levels depending
on the kind of business you are in:
Film Video Music
83 dB(C) 78 dB(C) 78 to 93 dB(C)
►
Select the first monitor (L).
►
Play the track from the Dynaudio Professional AIR
test tone sets related to this monitor.
►
Set Calib to 0.0 dB.
►
Adjust the global volume until the desired
C-weighted level is obtained on a sound level me-
ter in the listening position.
►
Proceed to the next monitor.
►
Adjust Calib until the same C-weighted level is
obtained from this monitor.
►
Repeat this procedure until all monitors are cali-
brated.
►
Exit Calibration.
