PROGRAM CONFIGURATION CONTROL
Once IntelliGain
is configured for the desired audio programs, the VistaLINK
®
program configuration
tabs will become activated. The user interface and program configuration tabs are identical.
Sections 3.1.1 to 3.1.10 provide detailed explanations for each control available in the Program
Configuration tab. Since each program configuration interface is identical, only Program 1 will be
described.
3.1.1. Setting the IntelliGain
State
Program 1
The
IntelliGain State
control is the master switch for the IntelliGain
processor, which is used for the given audio program. Set this control
to
Enable
to initiate IntelliGain
processing.

3.1.2. Setting the Leveler State
Program 1
The
Leveler State
control is used to activate the IntelliGain
audio
leveler. The leveler is used to level each individual audio channel to
the target loudness level. Set this control to

3.1.3. Setting the Target Loudness
Program 1
The
Target Loudness
control is used to set the target loudness level
for the given audio program. The IntelliGain
processor will level the
audio to this value. Note that if the compander is enabled, it is
desirable to set the target loudness parameter to the range (–31 LKFS
to –26 LKFS) and use
Makeup Gain
control to reach the final desired
target loudness level.
Target Loudness
–35 LKFS to –15LKFS
-24 LKFS (ATSC)
-23 LKFS (EBU)
3.1.4. Setting the Maximum Gain
Program 1
The
Maximum Gain
control is the total amount of gain that the
IntelliGain
engine will apply. For example, setting this control to 10
LKFS indicates that IntelliGain
is not to add anymore than 10 LKFS
of gain to the audio program, even if the audio program requires more
gain to reach the target loudness level.
Maximum Gain
0 to 40 LKFS

3.1.5. Setting the Noise Floor Threshold (If Available)
Program 1
The
Noise Floor Threshold
control is used to set the threshold level for
IntelliGain
processing. Levels below this value will not have
IntelliGain
processing applied.
Noise Floor Threshold
–70 LKFS to –40 LKFS
