Omnia 4.5 Use and Installation Guide – Ver 1.00a

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 4.5 metering Display

Note: To view the Meter Display from the Main Menu (or from anywhere in the Menu Display) simply

press and hold the jog-wheel button for two seconds

. The display will switch to the Meter display. To go

back to where you left off in the Menu Display just press and hold the jog-wheel again for two seconds.

You will be returned to the Menu Display screen right where you left it.

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-

4.5fm. 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 Omnia4.5-fm has the musicality and clarity that other processors lack.

Another feature unique to Omnia4.5-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.
