System Calibration - DigiDesign D-Control Manual

Center Meters Track/Output
The Center Meters Track/Output preference toggles the
8-channel meter display on the Main Unit meter bridge be-
tween main output levels and the focused track. When set to
meter the focused track, you can view levels for multichannel
tracks up to 8 channels (7.1 surround).
To toggle the center meters between output and track metering:
In the Soft Keys section, press the Meter switch repeatedly to
1
display the page that includes the Center Meters Track/Output
preference ("CtrMtr").
Press the Soft Key that corresponds to "CtrMtr" to toggle the
2
setting between "Output" and "Track."
Hold Control (Windows) or Command (Mac) and press the
3
Meter switch to exit.
Gain Reduction Priority
When encoder LED rings and channel meters are set to display
dynamics plug-in gain reduction, you can set which function
has priority when multi-function Compressor/Gate plug-ins
are used.
To set the gain reduction metering priority:
In the Soft Keys section, press the Meter switch repeatedly to
1
display the page that includes the Gain Reduction Priority
preference ("GRPrio").
Press the Soft Key that corresponds to "GRPrio" to toggle the
2
setting between Compressor/Limiter ("CompLm") and Ex-
pander/Gate ("ExpGat").
Hold Control (Windows) or Command (Mac) and press the
3
Meter switch to exit.
VCA Slave Metering On/Off
The VCA Meters On/Off preference toggles metering of VCA
slave track levels on VCA channel rotary encoders on and off.
To toggle VCA slave track metering on and off:
In the Soft Keys section, press the Meter switch repeatedly to
1
display the page that includes the VCA Meters On/Off prefer-
ence ("VCAMtr").
Press the Soft Key that corresponds to "VCAMtr" to toggle
2
the setting On and Off.
Hold Control (Windows) or Command (Mac) and press the
3
Meter switch to exit.

System Calibration

Recalibrating D-Control Faders
If a fader on a D-Control Unit shows response problems, you
can recalibrate the faders with the Recal command in Utility
mode. See "Recal" on page 161 for details.
Calibrating the Output Meters
You can calibrate the output meters on the Main Unit meter
bridge from XMON, in order to match metering levels in
Pro Tools with metering levels of external sources. The exam-
ple below uses a Digidesign 192 I/O as the reference source.
To calibrate the D-Control output meters:
Set the reference level of your 192 I/O according to the in-
1
structions in the 192 I/O Guide.
With the 192 I/O analog output connected to the XMON
2
Main Input, send a calibration tone to the D-Control Main
Outputs, and note the output level on the D-Control meters.
Disconnect the 192 I/O analog output from the XMON
3
Main Input and connect it to the XMON Alt Input.
Activate the Alt Output.
4
Adjust the trim pots on the back panel of the XMON until
5
the output level for each channel on the D-Control matches
the level displayed for the Main Output.
When you are finished, reconnect the 192 I/O analog out-
6
put to the XMON Main Input.
Calibrating SPL Indication on the Monitor Section
The D-Control Monitor section lets you display output level
in dB or dB SPL. You can calibrate the SPL display to reflect the
sound pressure level at the mix position. See "Calibration
Mode Switch" on page 118.
