AM MENU
Input AGC, Wideband AGC 1, and Wideband AGC 2 Menus
The
Input AGC, Wideband AGC 1,
and
Wideband AGC 2
menus in Expert mode each add a 3-band
Sidechain
Equalizer
which allows you to make it more or less sensitive to particular frequencies. When the controls are not
set to cut or boost any frequency, the Input AGC behaves like a traditional wideband processor and reacts to the full
audio spectrum. When set to cut or boost a particular range of frequencies, the Input AGC becomes less sensitive
(cut) or more sensitive (boost).
Additionally, an assortment of pre-configured filters are available including a Low Pass Filter, a High Pass Filter, a
Band Pass Filter, a Notch Filter, a Low Shelf EQ, and a High Shelf EQ.
Note:
It is important to remember that this equalizer has no direct effect on shaping the spectral balance
of the audio and operates in the sidechain control circuit only.
The settings for the Wideband AGC1 should, in most cases, mirror those of the Input AGC sidechain equalizer
since Wideband AGC 1 is used as an additional full-spectrum AGC.
For Wideband AGC2 used in the Bass Only mode, however, you may want to make the compressor more sensitive
to very low frequencies by setting a 2dB boost at 23Hz with a 3 Octave width. This will yield more gain reduction
and thus slightly less sustained deep bass in order to protect against the possibility of causing intermodulation
distortion which is more audible with a combination of sub-bass plus “ess” sounds than mid-bass plus “ess” sounds.
The controls of the equalizer itself work in the same manner as their counterparts in the other sections of the
Omnia.7 as explained earlier in this manual.
Note:
You can see a visual representation of the sidechain EQ curve in a display window using Omnia.7’s
built-in RTA by navigating to
AM > Processing > Display Settings
and choosing the specific patch
point for each sidechain. A full explanation of Display Settings is provided in Chapter 11.
Dry Voice Detection Menu
In Expert mode, the
Speech Detection
menu has three additional sub-menus:
AGC Speed, AGC Target,
and
Limiter
Target.
♦
The
Attack, Release, Target, Limiter Threshold, Attack (coupled), Release (coupled),
and
Speed
(coupled)
controls found throughout these sub-menus are work in conjunction with and are relative to
the controls of the same names found in the main multiband AGC menu. These settings come into play
only when Speech Detection is set to “Forced” or when it is set to “Auto” and speech is detected.
♦
The
Peak Sense (Coupled)
control in the
AGC Speed
sub-menu simultaneously adjusts the attack and
release rates but in opposition to one another. Sliding the control to the right increases the attack rate and
slows the release rate, making it more peak sensitive. Sliding the control to the left decreases the attack
rate and speeds up the release rate, making it less peak sensitive.
