The 

Window

 

function 

(also in the 

Advanced

 

tab) provides a "dead band" area for the wideband AGC.  If you set it 

at -2 dB 

for example

, you

're telling the wideband AGC

 that if the 

source material is within 2 dB of the 

target level, 

do nothing.  This 

will al

l

ow 2 dB 

of natural 

level variation in the audio, which

 

is nice for keeping the 

Omnia.11 

from over-

processing already dense material.  

 

 

T

he lower you set the number (say, from 

-2 dB to -6 

dB),

 

the more variation in programming levels you're allowing 

through...and the more "relaxed" the audio sounds.

 

See the Basic and Advanced tab sections below for more details.

 

 

Wide Band AGC Metering (Summary Tab) 

 

Touch the 

Wide Band 

icon button to enter the metering and menu screens for the Wideband AGC.

 

 

The WB AGC meter indicates gain

-

reduction from the top down in d

B

. The Stereo Enhance meter indicates the 

amount of activity in the stereo enhancer fro

m the bottom up.  

 

Gating activity is indicated by a bright yellow outline (Gate Indicator) around the blue gain

-

reduction meter. The 

gate indicator will

 

show more gating activity than you 

may be 

used to in conventional processors, but this is normal! 

The Omnia.11’s “smart” 

windowed gating algorithm will control levels over a wide 30dB+ range and can choose to 

do nothing when appropriate as well as increasing or reducing gain.
