Hardware
not selected), the following adjustments are available.
Surround Field Adjustments
The “surround field” can be adjusted with the Center channel Width
control and the Surround channel Depth control.
AutoMAX-II Transition Speed
When the upmix operates in AutoMAX-II
tm
mode, the speed of the
transitions from 2.0 to 5.1, and 5.1 to 2.0, can be configured to provide
smooth and unobtrusive changeovers.
•
Set the “Upmix-to-Pass” and “Pass-to-Upmix” transition speeds
independently, over the range
Instant
to
Very Slow
5.1/2.0 Detection Threshold
This parameter is used when the upmix operates in AutoMAX-II
tm
mode
to detect silence on some of the 5.1 channels to determine if 5.1 or 2.0
is detected.
LFE Output Channel
The bass enhancement signal for the LFE channel is derived from the
Left, Center and Right channels. The LFE checkbox and LFE Channel
Level slider control the LFE output
6.6.3 Loudness Monitoring
Loudness monitoring and ALC are accessed through the various PGMX
tabs that appear in the Audio Modules panel.
•
The tabs that appear are determined by the configuration
selected in the Config tab
•
Each program has a tab of its own, e.g. PGM1, PGM2, PGM3,
etc.
•
If PGM1 is 5.1, and its LFE is not linked, the LFE will have its own
tab, PGM1-LFE
Automatic Level Control using the Jünger Audio Level Magic
tm
system
can be enabled or disabled for each program.
•
Select the Bypass checkbox beneath the graphic to disable the
ALC
When enabled, the loudness meters display the input loudness (before
ALC processing), the dynamic correction applied by the ALC, the limiter
correction applied by the ALC, and the program output loudness (after
ALC processing). The input and output loudnesses are given in
LKFS
,
based on ITU-R BS.1770.
