Meter Calibration Procedure - PRESONUS CENTRAL STATION User Manual

OPERATION
3 . 3 M E T E R C A L I B R A T I O N
The meters of your CENTRAL STATION can be calibrated to match the meters in your DAW or other
audio device. Note that the main audio path does not go through the meters of your CENTRAL STATION
and the calibration procedure will not affect the sound of your unit.
To calibrate the meters on your CENTRAL STATION to an external DAW or audio device:
1. Input a 1kHz 0dBu sine wave test tone to ANY input on your CENTRAL STATION. Select the input you
are using in the MAIN INPUT SELECT section on the front panel. In a computer based recording system,
this can be accomplished by creating an audio channel and assign a test tone to it by either a tone
generator, plug-in or wav file.
2. Decrease the volume of the test tone channel until the meter on your DAW master section reads (-
18dB).
3. Press and hold the calibration button on the front panel of the CENTRAL STATION for two seconds.
The meter will recalibrate to read -18dBfs / 0dB.
4. Then raise the level of the test tone until the meter on your DAW's master section reads 0dB and
check if the CENTRAL STATION reports a clipped (RED) signal.
5. For more accurate calibration raise or lower the test tone level plus or minus 0.10 dB and repeat steps
2 thru 4.
6. Note that the range of the calibration of the CENTRAL STATION is approximately +/-12dB.
