Expander Rates Menu
The Expander Rates menu provides controls for the attack and release speeds of the expanders for each band as well as attack
and release speed controls for each band’s speed governors.
♦
The Expander Attack speed control determines how quickly each band’s expander will rise when the audio is in need of
expansion. Faster settings will expand the audio more quickly. Using the built-in oscilloscope to view the Undo Control
Signal patch point is very helpful for adjusting attack and release speeds as they show the gain that will be applied to the
audio in each band. A detailed explanation of how to monitor various patch points within Omnia.9 is provided in the
Display Settings menu of this manual.
♦
The Expander Release speed control adjusts how quickly the expander levels will fall once the expansion is no longer
called for. Faster settings will allow the levels to fall more quickly.
Undo also utilizes a second set of parallel expanders which look at the same input and automatically scale the attack and release
characteristics of the main expanders. These Speed Governors detect when the main expanders have been operating at full
speed for an extended period of time and will slow down the main expanders.
♦
The Governor A ttack speed determines how long the speed governors wait before scaling back the speed of expanders.
Faster attack speeds will cause the speed governors to slow down the expanders more quickly.
♦
The Governor Release speed setting determines how quickly the speed governors give up their influence on the main
expanders.
The effect of the expander attack and release speeds are indicated by the Multiband Expander meters in the Undo Meter
window. The levels of the speed governors are indicated in the Speed Governors window.
