System Calibration

Recalibrating D-Command Faders
If a fader on a D-Command Unit shows response problems,
you can recalibrate the faders with the Recal command in
Utility mode. See "Recal" on page 105 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-Command 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-Command Main
Outputs, and note the output level on the D-Command
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-Command
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-Command Monitor section lets you display output
level in dB or dB SPL. You can calibrate the SPL display to re-
flect the sound pressure level at the mix position. See "Cali-
bration Mode Switch" on page 85.
