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

 
 

 

Adjusts the amount of gain reduction in the Presence Band AGC. Higher numbers result in more  

 

 

drive and because of the increased compression, a more consistent output from the band. 

 

Hi Drive 

 
 

 

Adjusts the amount of gain reduction in the High Band AGC. Higher numbers result in more drive 

 

 

and because of the increased compression, a more consistent output from the band. 

 

OV AGC Drv (Overall Multiband AGC Drive) 

 

Adjusts the overall amount of drive to all four bands of the 4-Band AGC section simultaneously 
over a + / - 6 dB range. Higher settings will increase the overall amount of compression and the 
“dynamic EQ” effect of the 4-Band AGC. This can make the program material sound more 
consistent. Be careful though because too much compression can cause the program material to 
sound less natural and cause low-level noise in the program material to be brought up.  
 

 

 

OV Lim Drv (Overall Limiter Drive)

 

 

 

 
Adjusts the overall amount of drive to all four bands of the multiband Limiter section 
simultaneously over a + / - 6 dB range. Higher settings will increase density. This can increase 
loudness but be careful because too much gain reduction in the limiters can lead to a “wall of 
sound” effect that can cause the program material to sound “smashed”. This can also cause 
additional artifacts to be generated in the following codec. Lower settings will reduce the density, 
providing a more “open”, natural and dynamic sound.

Low Band AGC 

 

Attack 

 

The attack control adjusts how fast the AGC 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 later stages to be overloaded during the time when the AGC is 
adjusting the level downwards. Likewise, extremely fast attack times (especially when combined 
with very slow release times) can “punch holes” or overreact to the band of audio being processed. 

Release 

 
 

 

The release control adjusts how fast the AGC 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’. 

 

Gt Thresh (Gate Threshold) 

 
 

 

When the input audio falls below a certain level, the gain control action of the AGC stage is  

 

 

“frozen” by the gate. The level at which this freeze, or hold takes place is controlled by the setting  

 

 

of the Gate Threshold control. Higher numbers cause the gate to activate at higher audio levels. In  

 

 

most applications this control should be adjusted to cause gating action to occur when the input  

 

 

audio falls about 20dB below nominal. The action of gate also prevents noise rush-up during  

 

 

periods of no audio or during pauses in speech.
