Quick-Start inStallation Guide
We have made this Omnia processor easy to set up and configure. This quick-start guide will take you through the
basic steps needed to configure your new Omnia VOLT. You’re just a few steps away from being able to deliver cleaner,
clearer, louder, and more consistent FM sound. Before we get started, let’s make sure you have what you need.

1. The VOLT SG is designed to accept pre-processed audio from an external FM audio processor. Ideally,
this audio should be pre-emphasized and sourced only through a lossless link using Livewire or AES/EBU.
AnalogL/RXLRinputcanalsobeaccepted.SincetheVOLTSGincludesacompositeclipperforremovalof
overshoots, it is very important to calibrate the input level properly so that when the Composite Clip Drive
control is set to 0.0, no composite clipping is taking place. The input level for 100% modulation (composite
clip threshold) is -12dBFS. On the analog input, this corresponds to 10dBu.
Using typical program material, temporarily turn up the main clipper drive on your external FM processor
to provide a more steady “worst-case” level at the input of the VOLT SG. If using a digital output on the
external FM processor, set its peak output level to -12.0dBFS if possible. If so, set the Omnia’s input Level
control in the Discrete I/O / Input menu to 0.0dB to start.
Note: The VOLT SG’s input meters are specially calibrated with higher resolution above -12dBFS for
easy and precise input level calibration. Above -12dBFS, the input meter on the front panel has a "zoom"
function.Itzoomsby10X,soeachsegmentis0.4dBinsteadof4dB.Thatis,theactualvalues,going
up from -12dB are: -12.0dBFS, -11.6dBFS, -11.2dBFS and -10.8dBFS. Any value higher than that just
saturates the meter. The composite clip point (with 0.0dB drive setting) is -12.0dBFS. Note that on the
web GUI, there is a separate "Input Zoom" meter with more range.
2. Adjust VOLT’s appropriate input Level control until the peak-reading input bargraph meters are just
lighting only the -12 LED. If there is some overshoot in the output of your external FM processor or
the link between it and the VOLT SG, more than just the -12 LED may light. This should be OK as long
as there is not more than a dB or so of overshoot. (remember, the meter scale above -12 is 0.4dB instead
of 4dB so the red 0dB LED indicates +1.2dB) If there is more overshoot than that and the red 0 LED is
flashing frequently or is on steadily, you may need to lower the input level a bit. Press the jog wheel to
accept the setting.
3. Rotate the jog wheel until Exit is highlighted. Press to return to the Discrete I/O menu screen.
Highlight Exit again and Press to return to the main menu.
4. Ideally, the de-emphasis in the output of your external FM processor should be defeated so that the VOLT

Press the jog wheel (K) to make a navigation selection or to enter settings.
2. If you’re using L/R audio to feed a monitor or other stereo generator, once you are on the Discrete I/O
menu screen, rotate the jog wheel until Output is highlighted. Press to select.
3. Rotate the jog wheel to highlight the appropriate Level control for the output being used. Press to select.
4. Rotate the jog wheel to adjust the output level as appropriate for the next device. Press to accept the
setting. De-emphasis for each output can also be turned on here if needed.
5. Exit and return all the way to the main menu screen.
6. Rotate the jog wheel to highlight Stereo Generator. Press to select.
7. Rotate the jog wheel to highlight Adjust SG. Press to select.
8. Navigate down to the Comp #1 or Comp #2 controls and adjust the appropriate control for 100%
modulation on your station’s modulation monitor. Similarly, adjustthePilotLvlcontrolsothatthe

9. To save your settings as an SG Config preset, navigate to the Save SG Config setting in the Stereo
Generator menu, click on “Name”, enter a preset name using the jog wheel, turn the jog wheel one
more click clockwise and click on “Save”. Similarly, I/O configuration presets can also be saved from
the Discrete I/O menu.
10. Remember to return your external FM processor’s main clipper drive control to its previous level.
Note: To engage the special single-sideband mode available in the VOLT SG, navigate to the Stereo
Generator / Adjust SG submenu and set the SB Mode control to “SSB”. No other adjustments should
be needed.
