FM MENU EXPERT MODE
Wideband AGC 1 Menu
The Wideband AGC1 menu provides access to the sidechain delay, maximum gain, maximum gain reduction, ratio, attack,
release, progressive release, target, gate threshold, freeze threshold, and three-band sidechain parametric equalizer controls.
♦ 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.
