Clipper Menu
The Clipper Menu provides control over the stereo mode (Single-‐ or Double-‐Sideband), final clip
drive, pre-‐emphasis level, bass clipper slope, bass clipper threshold, low frequency protection, high
frequency protection, A15 protection, L/R Output bandwidth, and MPX Audio bandwidth.
The Stereo Mode control allows you to choose between single-‐sideband (SSB) or double-‐
sideband (DSB) operation.
The Final Clip Drive control sets the drive of the final clipper. Decreasing the drive (moving
the slider to the left) reduces the amount of clipping. Conversely, increasing the drive
(moving the slider to the right) will result in more clipping. Less clipping will result in a more
open, less-‐processed, cleaner sound, but at the expense of overall loudness. More clipping
can result in a louder on-‐air sound – but only up to a point. Even if total dial domination and
loudness are your processing goals, there comes a point when the final wave form is
completely full, and increasing the amount of clipping will no longer yield additional
loudness – only more distortion.
We strongly recommend using Omnia.9’s oscilloscope as well as your ears to monitor the MPX
Output signal while adjusting the final clip drive. This control ranges from -‐6.0 to +6.0 in one-‐
quarter dB increments, which should give you the (correct) impression that small changes make a
big difference in the sound. Keep in mind that a setting of +0.00 means the control is at the middle
of its range, but does not necessarily mean that no clipping is taking place.
The Pre-‐Emphasis controls allows you to select a pre-‐emphasis curve of either 50 or 75us,
depending upon the country in which Omnia.9 is being used.
The Bass Clipper Slope control determines the slope characteristics of the bass clipper.
o
Slope 1 is filtered at a very low frequency so that the low bass stays “clean” even when
clipped hard. However, some of the mid-‐pass will pass through the clipper, which may
result in more of the final waveform being taken up by the bass. For lighter processing
settings, Slope 1 offers the cleanest and punchiest bass sound.
