Pres Drive
Adjusts the amount of gain reduction in the Presence Band AGC. Higher numbers result
in more drive and because of the increased compression, a more consistent output from
the band.
Hi Drive
Adjusts the amount of gain reduction in the High Band AGC. Higher numbers result in
more drive and because of the increased compression, a more consistent output from the
band.
OV AGC Drv (Overall Multiband AGC Drive)
Adjusts the overall amount of drive to all four bands of the 4-Band AGC section
simultaneously over a + / - 6 dB range. Higher settings will increase the overall amount
of compression and the “dynamic EQ” effect of the 4-Band AGC. This can make the
program material sound more consistent. Be careful though because too much
compression can cause the program material to sound less natural and cause low-level
noise in the program material to be brought up.
OV Lim Drv (Overall Limiter Drive)
Adjusts the overall amount of drive to all four bands of the multiband Limiter section
simultaneously over a + / - 6 dB range. Higher settings will increase density. This can
increase loudness but be careful because too much gain reduction in the limiters can lead
to a “wall of sound” effect that can cause the program material to sound “smashed”.
Lower settings will reduce the density, providing a more “open”, natural and dynamic
sound. It may be helpful to think of the limiters as “dynamic clipper allocators”, acting as
“gatekeepers”, controlling the density of the audio signal that reaches the following
clipper.

Low Band AGC
Attack
The attack control adjusts how fast the AGC responds to sudden increases in audio level,
and higher numbers equate to faster response times. Faster attack times reduce the
transient nature of the input audio, while slower attack times improve it. Extremely slow
attack times must be used with caution so as not to allow later stages to be overloaded
during the time when the AGC is adjusting the level downwards. Likewise, extremely
fast attack times (especially when combined with very slow release times) can “punch
holes” or overreact to the band of audio being processed.
Release
The release control adjusts how fast the AGC recovers from periods of more gain
reduction when the input audio levels fall. Faster release times (higher numbers) result in
a more dense sound. Even though the Omnia uses program controlled release algorithms,
setting the control for extremely fast release times can result in ‘pumping’.
