To adjust the levels of each of the composite outputs, navigate to the Omnia.9sg > Stereo Generator >
MPX menu and adjust the corresponding “MPX Output Level” sliders until the desired modulation is
indicated on a dedicated, calibrated modulation monitor. The “Pilot Level” and “Pre-emphasis” controls
are also found here.
If the AES outputs will be used to feed an Omnia Direct signal, navigate to the Omnia.9sg > Stereo
Generator > Digital Output menu and choose the appropriate source to feed the digital output.
Adjust FM Diversity Delay
If the output of Omnia.9sg needs to be delayed to match an HD signal, the adjustment can be made in
the Omnia.9sg > Stereo Generator > Diversity Delay menu. Double-clicking on the “Diversity Delay”
slider will provide course, medium, and fine adjustment sliders to make adjustment easier.
ITU-R BS.412 (MPX Power Limiting)
Omnia.9sg supports ITU-R BS.412, which requires that average MPX power be limited to a particular
standard and measured with a rolling 60-second integration time.
If Omnia.9sg is used in conjunction with Omnia.7 or Omnia.9, the BS.412-specific presets in those
processors should be used.
Any adjustments to the MPX power limiter should be made in the Omnia.9sg via the controls in the
Omnia.9sg > Stereo Generator > MPX Power Limit menu keeping in mind that it may be necessary to
set the “MPX Power Limit” slider to very different levels than the settings in the processor’s preset to
achieve the same power output level.
