Low Band Limiter
LFLim Drv (Low Frequency Limiter Drive)
Adjusts the drive level to the individual Limiter band. Used when you desire more or less density
in a specific band. These Limiter Drive controls can also be used as secondary dynamic EQ
controls after the Drive controls in the AGC Xover.
To adjust the overall amount of density, use the Overall Limiter Drive control in the Xover
section. See “OV Lim Drv” in the Xover (Crossover) section on Page 104.
LFLim Att (Low Frequency Limiter Attack)
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 so as not to allow the Final Limiter stage to be overloaded 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 while driving the limiter hard can result in ‘pumping’ as well as
extremely dense-sounding (fatiguing) audio. Also, setting the control for extremely slow release
times (especially when combined with fast Attack times) can cause the limiter to “hang” after a
transient, failing to fully recover and “punching a hole” in its band of frequencies.
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.
