The Target control sets the target output level of the Input AGC. A lower setting results in a
lower output level, while higher settings provide a higher output level. This is similar to a
traditional “threshold” control when the levels are below the target.
When disabled, the Sidechain Filter allows the Input AGC to react to the full audio
spectrum. When enabled, it utilizes a hidden and non-­‐adjustable parametric equalizer and
causes the Input AGC to become less sensitive and reactive to very low frequencies and a
particular range of upper-­‐mid frequencies. The default (and recommended) setting for this
control is “On” to ensure the Input AGC is not controlled by the bass or by strong female
vocals. For reference, the PEQ settings of the Sidechain Filter are a 4.0 octave-­‐wide cut of
20dB at 20Hz and a 2.9 octave-­‐wide cut of 10dB at 2343Hz.
Wideband AGC1 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 Omnia.9’s Wideband AGC1 follows the Input AGC section and provides additional wideband
compression as determined by its various controls.
The Sidechain Delay slider allows you to slightly delay the reaction of the Wideband AGC1
compressor, allowing transients to be handled by subsequent portions of the processing
chain, a useful tool for adding punch.
The Wideband AGC1 Enable button enables the sidechain parametric equalizer, which
allows you to make the WD AGC1 more or less sensitive to particular frequencies.
The Maximum Gain, Ratio, Attack speed, Release speed, 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.
