Omnia Industries Food Processor Omnia One Multicast Stero Audio Processor with SENSUS Manuel D’Utilisation

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.  
 

 

Lim Thresh (Limiter Threshold) 

 

This control adjusts the threshold level of where limiting begins. Lower settings will increase the 
amount of limiting and decrease the level going to the following Bass Clipper (low band only) or 
Final Limiter stage. Conversely, higher settings will raise the limit threshold, causing less limiting 
but feeding more level into the following Bass Clipper (low band only) or Final Limiter stage. 
Normally, we recommend leaving the Limiter Thresholds at the factory setting.

Bass Clipper 

 
The Bass Clipper operates between the output of the Low Band Limiter and the Low Band Mixer, the output of 
which feeds the Final Limiter. Its purpose is to keep excessive bass out of the Final Limiter, reducing IM 
(intermodulation) distortion while keeping and even enhancing the bass punch of the program material. There are 
two different Bass Clipper styles available. (Described below.) 
 
 

Clip Drv (Bass Clipper Drive) 

 

 

 

 
Adjusts the drive level to the Bass Clipper over a range of +/- 6 dB. Higher settings will increase 
the amount of Bass Clipping, increasing bass density while keeping the actual peak bass level fed
