RUNNING THE FIRST CALIBRATION (STEP-BY-STEP)
SEVERE NOISE INJURY MAY OCCUR DURING THE CALIBRATION PROCESS IF THE FOLLOWING
INSTRUCTIONS ARE NOT STRICTLY APPLIED.
ANY PERSON PRESENT IN THE ROOM DURING CALIBRATION SHOULD BE WARNED ABOUT THE RISK
OF NOISE OVERLOAD AND THE LARSEN EFFECT.
The Optimizer requires a minimum Sound Pressure Level for proper calibration. Until the minimum SPL is reached, the test signal
will play through the same speaker. For safety reasons, we recommend running the first calibration as if it were a test. Start with
a Master Level of -40 dB and increase the level until the test signal passes on to the second speaker. This confirms that the
minimum SPL has been reached.

1
Open the OPCP GUI by clicking on the D-Mon
processor model number from the DMCP.
See
6.4.1: Working with the DMCP & OPCP
2
Select the “Setup” page followed by the “Clock”
sidebar tab:
Set the sample rate to 48kHz, whether as
the Master or Slave to an external clock.
In the case of an external clock, select a
valid Clock Source and make sure that a
48kHz sample rate is displayed on-screen
to show that it has been accepted.

Select the “Processor” page:
In the “Meters,” “Master” and “Outputs”
sidebar tabs, set the output parameters to
convenient values.
Any parameter can be changed later and
saved in a different preset.
The default values ensure an overall gain
of 0dB. Therefore, you should only change
parameter values if necessary.
