Wideband Agc 1 Menu - Omnia .9 Installation & User Manual

FM MENU INTERMEDIATE MODE
The Gate Threshold and Freeze Threshold controls work together to determine the points at which the release rate of the
♦
Input AGC slows by a factor of 3 (gate threshold) or freezes altogether (freeze threshold). The range of these controls is
-90dB to 0dB. Lower settings means the audio must drop to a lower level before the release speed slows or freezes. Higher
settings means the audio doesn't have to drop as much in level before the input AGC gain slows down or stops. Using
higher settings when employing faster Input AGC release speeds can keep the audio from being increased too quickly
or too much during quieter passages or pauses. If the display is sized and configured in such a way that the Input AGC
meter is shown vertically, a Gate condition will be indicated by a dim, dark red bar at the bottom of the meter. A Freeze
condition will be indicated by a brighter dark red bar.

Wideband AGC 1 Menu

The Wideband AGC1 menu provides access to enable and bypass controls, maximum gain, maximum gain reduction, ratio,
attack, release, progressive release, target level, gate threshold, freeze threshold and sidechain delay.
The Wideband AGC1 Enable button enables this section, which follows the Input AGC section and provides additional
♦
wideband compression as determined by its various controls. Disabling the Wideband AGC1 also makes this patch point
unavailable in an oscilloscope or RTA display window.
The Bypass button removes the Wideband AGC1 compressor from the audio path, but its patch point remains an
♦
available option for viewing on the oscilloscope or RTA via the Display Settings menu.
The Sidechain Delay feature is useful for both adding punch and managing the amount of low frequency power (while
♦
increasing bass punch). This is an especially useful "trick" for maintaining apparent loudness when operating under
MPX Power regulations.
The Maximum Gain, Ratio, Attack rate Release rate, Target, Gate Threshold, and Freeze Threshold controls work in the
♦
same manner as their counterparts in the other sections of the Omnia.9. However, the Maximum Gain control in the
Wideband AGC1 section has a range of 24db.
The Maximum Gain Reduction control sets the maximum amount of gain reduction possible in the Wideband AGC1
♦
compressor, and is adjustable from 0 to 24dB in one-quarter dB increments.
The Progressive Release control determines the degree to which the Wideband AGC1 compressor releases its gain at a
♦
faster rate as the audio is driven further toward or into gain reduction. At a setting of 0, the control has no effect and the
Release speed control fully determines the rate of release. Increasing the setting progressively makes the release speed of
the audio faster as gain decreases.
