Level Meters & Processing Bargraphs
The horizontal meters show sample-
accurate peak and VU representations of the
left and right input and output levels, while
the vertical bargraphs show processing
activity of the various algorithms. The
currently selected Preset Name is displayed
in the bottom left corner of the Meter
Display, while the current time is displayed
in the lower right corner.
Omnia 4.5 "Metering" Screen
Audio I/O Level Display
When the metering display has been selected both input and output levels are shown in real time. The bars
indicate VU while the “bouncing balls” indicate sample-accurate peak signal levels. The horizontal meters
show the signal levels below full scale digital (0 dBFS), which is the absolute maximum level in the digital
domain. In normal operation, the VU metering should average about -15 dBFS (-12 dBFS is approximately
equivalent to 0VU in the analog domain). Note that when the Main Menu is selected, the Output Levels
ONLY are displayed on that screen.
Processing Display
The nine vertical bargraphs in the lower half of the Meter Display show the processing activity in real time
within the Omnia-4.5fm. The first vertical meter (labeled W) represents the processing activity in the
Wideband AGC section. The two vertical "AGC" meters show the processing activity in the low and high
band AGC sections. The five vertical "Limit" meters show the processing activity in each of the limiter
sections of the multi-band limiter. Each of the meters is capable of indicating up to 25 dB of gain reduction.
The rightmost vertical bar graph (labeled EFX) indicates the processing level of the optional Stereo
Enhancement effect, when that function has been activated.
Note: The wideband AGC and two-band AGCs will recover to a resting gain setting which coincides with
the RTP (Return To Platform) levels set for each band. Refer to Chapter 5 for more information on
interpreting and using the processing bargraph displays.
