Zero VU (dBFS) The Zero VU (dBFS) parameters determine the reference level to be
applied to the selected digital (embedded, or from ABT) audio signal.
dBFS stands for decibels full scale. Zero dBFS corresponds to the
maximum possible level. By default the reference level for a it is set to -
20
dBFS, on a range of -24 dBFS to -8 dBFS. The extraction of digital
audio requires the KXS-HD-EMB or KXS-SD-EMB option (see
Hardware
and Software Options, on page 383). Refer to Calibrating Zero VU
Reference Level for an Embedded Audio Source, on page 121 for details.
Loudness/dialnorm The dialnorm value that can be found in the Dolby VANC metadata is an
indication of the average level of dialogue in the audio stream. The
loudness is a measure of the average level of an audio stream. It is
possible to configure alarms that will be triggered whenever the
measured loudness is not within an acceptable range (1) compared to
the encoded dialnorm, or (2) compared to the reference dialnorm for
your organization, or (3) when the encoded dialnorm itself deviates too
much from the reference dialnorm for your organization. The related
parameters determine the loudness measuring standard you wish to
apply, the channels that are involved in the measurement, the reference
dialnorm level for your organization, and the ranges outside of which
alarms will be triggered. Requires the KXS-Loudness option (see
Hardware and Software Options, on page 383). Refer to Calibrating
Dolby VANC Loudness Measurement, on page 123 for details.
Dolby E selection Dolby E audio can be decoded from two of eight AES pairs within a
signal’s embedded audio stream. The Dolby E selection parameters
determine which AES pairs will be used. Requires the Dolby
E option (see
Enabling Options, on page 411). Refer to Calibrating Dolby E Audio
Metadata, on page 125 for details.
Router Output Calibrations
Switch field
selection
The switch field parameter determines whether the router module will
perform clean crosspoint changes on the odd (field 1) on the even (field
2) field, or on any field.
See Calibrating Switch Field Selection on
page 130.
SDI output
reclocking
The SDI output reclocking parameter determine whether digital video
signals will have their timing restored at the selected output, to
eliminate jitter. Reclocking is typically used in installations with large
routing devices or long cables in the signal path.
See Calibrating SDI
Signal Reclocking on page 131.
