• Input AGC. Reduce the Ratio to allow the average output level to vary over a wider
range. Increase ratio to decrease the average output range.
Note!
If an adjustment has no units then the adjustment controls more than one
parameter at a time and may also be program dependent.
• AGC Attack. Reduce to slow the reaction time of the AGC and allow the output level to
change when the input changes rapidly. Increase to speed the AGC reaction time and
reduce level changes of the output.
• Release. Reduce to make gain recovery slower. This will reduce overall level and
dynamics. Increase to make AGC gain recover more quickly. Setting a fast attack and a
fast release can make pumping of level audible.
• Gate Threshold. Raise the Gate Threshold to reduce AGC release time by ½ for levels
below the Gate setting. Raising the Gate above dialogueue level makes dialogueue
sound more natural.
• Freeze Threshold. The Freeze threshold does not allow the AGC to release until levels
exceed the Freeze Threshold. Adjusting Freeze to a level below the lowest dialogue
prevents increase in audio during quiet scenes.
Note!
Listen and watch the DRC, AGC, and Program Loudness meters for changes while
making any adjustments.
• Multiband Setup. The Multiband Freeze Threshold always tracks the AGC Freeze
Threshold. Changing either one changes both. The MB Gate Threshold works the same
way as the AGC Gate Threshold. The Multiband Gate and AGC Gate settings are usually
matched. If there is too much gain change during dialogue raise the Gate Threshold.
This will reduce the speed of multiband gain release in the dialogue region.
• Multiband AGC > MB AGC Main > Ratio. The ratio can be set to 1:1 to disable the
multiband AGC/Limiter. To create a wideband loudness controller set this to 1:1 and
use both the WB AGC 1 and WB AGC 2 to create a smooth single band system that does
