AM MENU
♦
Because all of Omnia.7’s processing stages are program-dependent, putting actual measures of time
on these controls would be pointless, and so the numbers on the various Attack and Release controls
throughout simply indicate to what degree the slider is advanced.
♦
The
Release
control determines the speed with which the Input AGC increases gain when the output is
below target. Lower settings provide slower release speeds, while higher settings result in faster release
speeds.
♦
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 except that gain may also be increased to reach the target, up to the maximum gain setting.
♦
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). 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. A Gate condition
will be indicated by a dim, dark red bar at the end 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 the sidechain delay, maximum gain, maximum gain reduction,
ratio, attack, release, progressive release, target, gate threshold, and freeze threshold controls.
♦
The
Wideband AGC1 Enable
button enables this compressor, which follows the Input AGC section and
provides additional wideband compression as determined by its various controls. Disabling the Wide-
band AGC1 also makes this patch point unavailable in an oscilloscope or RTA display window.
In contrast to the
Enable
button, 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. Its meters will remain visible, but dimmed.
♦
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.
