Calibration Procedure

9 - 46
For best "de-essing" results, try setting this parameter in the range
5kHz - 10kHz.
Depth: Maximum depth of the notch (0dB to 24dB, in 1dB steps).
Threshold: The detector level above which the notch starts to kick in.
There is a gradual knee, so the notch actually kicks in a few dB below
the threshold.
Sensitivity: How quickly the notch kicks in around the threshold point.
Sort of like a combined knee and ratio control. Three choices: Low,
Med, High.
Attack and Release time constants.
Dyn In (bypass switch).
The width of the notch filter is fixed (approximately one octave at
-3dB) and currently cannot be adjusted.
Because Dynamic Notch mode relies on accurate signal cancellation rather
than simple gain control, there is a calibration procedure which can be per-
formed in order to tune the accuracy of the circuit. This calibration procedure
is accessed from the Dynamics Utility menu in the SmartDisplay. The calibra-
tion procedure is performed on all units before they leave the factory, however
it is recommended that the procedure be performed every few months by the
user. The procedure requires a test tone to be injected into the channel being
calibrated, as indicated by the yellow window that appears on the MixView
screen when the "Calib" key is pressed. Only one channel can be calibrated at
a time, but the procedure takes only a few seconds per channel.
