The attack control adjusts how fast the limiter 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 because allowances must be made in the following final limiter stage so as not to
overload it during the time when the limiter is adjusting the level downwards.

LFLim Rls (Low Frequency Limiter Release)


The release control adjusts how fast the limiter 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’ as well as extremely dense-sounding

(fatiguing)

audio.

LFLim Hold (Low Frequency Limiter Hold Threshold)


During operation of the limiter, the algorithm is watching for very small decreases in audio level,

such as what occurs right after a sudden peak. When this occurs, the limiter release is temporarily

stopped. The result is a drastic reduction in intermodulation distortion and a more open sound,

even though the audio is still quite dense. The level at which the hold takes place is controlled by

the setting of the hold Thresh control. Higher numbers cause the hold to activate at higher audio

levels. The action of limiter hold also works in conjunction with the preceding AGC gates to

reduce noise rush up during periods of no audio or pauses in speech.

Mixer

Low Band


Adjusts the output level of the low band limiter into the following final limiting stage. Higher

numbers result in more low frequencies and too much mix level can make the following final

limiter work unnecessarily hard.

Mid Band


Adjusts the output level of the mid band limiter into the overall mix. Higher numbers result in

more mid frequencies and too much mix level can make the following final limiter work

unnecessarily

hard.

Presence Band
