The
Expander
Threshold
meters simultaneously show four different measurements about expander
activity. The bright yellow bars indicate the average levels; the orange bars indicate the peak levels; the
dark red bars indicate the distance limit (the greatest distance by which an individual band’s peak
detector can fall relative to the wideband level to prevent any one band from being expanded if there are
insufficient levels to begin with); the yellow “blips” indicate peaks.
De-clipper Menu
The
De-clipper
menu contains a single control to set the level of de-clipping in 5 stages. Lower settings offer more
conservative de-clipping action, while higher settings offer more de-clipping.
A setting of Level 5 the “normal” setting and recommended for most modern material which have been mastered
with high levels of compression and clipping. If your station primarily plays source material that has been cleanly
mastered, you may find lower settings are sufficient.
The most effective way to monitor exactly what the de-clipper is doing is to view the pre-de-clipper and post-de-
clipper waveforms side-by-side using Omnia.7’s built-in oscilloscopes. Details of how to configure the display
windows and set up the oscilloscopes are provided in Chapter 11 of this manual.
