SG Style
The Omnia ONE SG style is designed to accept the output of an external FM audio processor either directly or
through a linear digital STL system. It has no audio processing onboard except for a composite clipper stage
designed to remove small overshoots from the processed input audio if needed.
To get started, be sure you are at the main menu (if you see the Composite Clipper meter instead, click and hold the
Jog Wheel for 5 seconds to switch to the main menu screen).

Here you can select the factory default configuration or any saved user configurations.
Adjust SG
The wideband AGC rides the incoming audio levels like an automatic “hand on the fader”, keeping the average level
more consistent for the following 4-Band AGC stage, enabling it to stay in its “sweet spot”.
[Emph Std] (Emphasis Standard - 50us or 75us)
Set this to the pre-emphasis standard being used in your country. For North and South America,
75 µs is used. In Europe, Australia and New Zealand, 50 µs is employed.
[Pre-emph] (Pre-Emphasis Off or On)
For best performance, pre-emphasis should be performed in the FM processor that is feeding the
Omnia.ONE SG. So this setting defaults to Off. If you need to have the SG provide the preemphasis, you can turn it On here.
[Input LPF] (Off or On)
For best performance, the 16kHz low-pass filter function should be performed in the FM processor
that is feeding the Omnia.ONE SG. So this setting defaults to Off. If you need to have the SG
provide the low-pass filtering, you can turn it On here.
[Separation] (Stereo, -3dB, -6dB or Mono)
The stereo “sound field” can be reduced by 3 dB or 6 dB to suppress processing-induced multipath
that can occur in certain terrain and within certain transmission systems when heavy processing is
used. When a setting of -3 dB or -6 dB is used, the amount of L-R (perceived stereo effect) is also
reduced. However in difficult RF signal coverage areas, the amount of perceived multipath is
reduced as well, resulting in the perception of a much cleaner overall signal with better penetration
and coverage. The Omnia.ONE SG defaults to a setting of Stereo, using the full L-R signal. We
suggest that you leave it in that mode, but the other settings are available for those who wish to
experiment, including a setting of full Mono.
[Comp Drv] (Composite Clipper Drive - 0.0dB to 6.0dB)
Controls the drive to the Omnia.ONE SG’s built-in composite clipper.
