The Meter Display 
 
 
In addition to the Input and Output 
Levels display, the Meter Display 
also provides processing 
information in the form of vertical 
bargraphs, which indicate both 
AGC and Limiter Processing 
activity.

Omnia 6 Main Metering Screen 
AGC Metering 
The bargraphs for the AGC sections can indicate up to 25 dB of gain reduction. When the “bouncing ball” 
indicators on each bargraph change to RED, the Gate function is active for that band. 
Limiter Metering 
The bargraphs for the Limiter section provide a wealth of information about the peak control in Omnia-
6fm. The limiter algorithms automatically adapt the style of peak control being employed on a moment-by-
moment basis. This can be deduced if the metering is studied over time. During normal operation, the 
limiter indicators will have a dynamic “bounce” that you will be able to get a feel for. Every now and then, 
you will see the limiter react quickly and show a larger amount of gain reduction. Notice that the response 
is very fast. This action will recover very slowly, and return to “rest” with the main bargraph. This action 
will be easily noticed on material that is very dynamic in texture. It is partly due to this very special 
behavior that the Omnia6-fm has the musicality and clarity that other processors lack. 
Another feature unique to Omnia6-fm is limiter “Hold”. During brief pauses in audio, the limiter bargraphs 
will “freeze” and the “bouncing ball” changes from blue to red to show the limiter has entered the Hold 
mode of the algorithm; akin to the Gate function in the AGCs. This is most easily noticed when there is a 
“dry” voice being processed. The Limiter bargraphs, like the AGC section, can indicate up to 25 dB of gain 
reduction.
