This 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 dB to –26 dB) and use Makeup Gain control to reach the

15dBFs.

The Maximum Gain control is the total amount of gain that the IntelliGain engine will apply. For

gain to the audio program, even if the audio program requires more gain to reach the target loudness
level.
7.26.3.4. Noise Floor Threshold
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. The Target Loudness control has a full
