Expander Speed
♦
The Attack control determines the speed with which the Downward Expanders act to reduce gain in each band when
the program audio falls below the threshold. Lower settings provide slower attack speeds, while higher settings result in
faster attack speeds.
♦
The Release control determines the speed with which the Downward Expanders act to return gain to each band when the
program audio rises above threshold. Lower settings provide slower release speeds, while higher settings result in faster
release speeds.
♦
The “coupled” controls adjust all bands simultaneously. Speed (coupled) adjusts both attack and release at the same time.
Input AGC Menu
The Input AGC Menu is used to set the ratio, maximum gain, attack rate, release rate, target, gate threshold, freeze threshold,
and sidechain equalizer controls.
The Input AGC is the first gain control stage in Omnia.9 following Undo, and is designed to be used as a slower-acting leveler
ahead of the Wideband AGC1 and multiband compressor sections that follow it.
It is worth noting that traditional processors only act upon audio above a particular threshold. They are driven into various
amounts of gain reduction, but once the audio falls below the threshold, they
“
run out of room
”
or
“
top out,
”
and are incapable
of increasing the audio any further. They require some sort of make-up gain control later in the audio chain. The compressors
in Omnia.9 operate above AND below threshold, controlling the dynamics over a much wider range and do not require
makeup gain.
