The MPX generator control allows you choose from several key test tones.
o
Square is a 60Hz square wave useful for visualizing tilt.
o
Quick Sweep is a very fast 1,000 – 60,000Hz sweep with a click before each sweep,
designed to offer a visual reference as to the high frequency performance of your STL or
exciter. If you were to connect an oscilloscope to a calibrated tuner with MPX output
(such as the Belar Wizard, for example) this is the shape you would see if your STL or
exciter had a flat high frequency response. Any deviation from a flat high frequency
response means a loss of loudness and/or stereo separation.
o
400Hz is a full amplitude sine wave to allow you to set an exact 75kHz deviation with a
mod monitor.
o 0.5 – 5.0 and 0.5 – 30.0 are subsonic sweeps that allow you to see the extreme low
frequency response of your air chain.
o
31,187.6Hz, 13,586.7Hz, and 8,667.4Hz sine waves – the “Bessel Null” tones – allow you
to set exact +/-­‐ 75kHz modulation with a direct off-­‐air spectrum analyzer.
Display Settings Menu
The Display Settings Menu allows you to customize what is displayed in up to 8 different windows
on-­‐screen at the same time.
Each of the 8 Display buttons allows you to choose which processing parameters or visualizations
from one of Omnia.9’s valuable built-­‐in diagnostic tools are viewable in each window. The 7 main
groups are Undo Meters, Processing Meters, Input Meters, Loudness Meters, Oscilloscope, RTA,
and FFT Spectrum Analyzer. You can also turn off any or all of Omnia.9’s displays here – a handy
feature for keeping your processing meters and settings from curious eyes!
Since Omnia.9 can display such a wide variety of information about your station’s audio processing
and signal, it allows you to create and save up to six Display Presets, which are always visible in the
