program's RMS energy. During gain calculations, the incoming program's “average” level is established,
and gain adjustments, if needed, are made based on those calculations. This is why the AGC sections will
appear to move slower than the limiters ... they are making changes, as needed, over relatively long time
periods.
The intent of the Limiter sections is to control the peak levels. This is accomplished by finding and
controlling the highest peak of the audio waveform. The Limiter section's job is to quickly grab the signal,
reduce the gain to the proper operating range, and then return the gain to normal until the next peak signal
comes along. Peak energy must be detected and adjusted in a quick and accurate manner while, at the same
time, not interfering with the sonic integrity of the audio signal. For this reason, the Limiter sections
operate very quickly, with special background instructions to govern their behavior, and strictly on an as-
needed basis.
Since the processing displays are capable of providing a wide range of information, we do not recommend
setting up the system based on any specified meter indications. Instead, we recommend setting up the
processing by using your ears to judge the sound. We've provided the meters only to analyze the signals
and aid you in adjusting the specific parameters needed to achieve your desired sonic results. Like a
speedometer, the meters are a guide, not the road!
Our Factory Presets Are Only Starting Points!
Numerous factory presets have been provided for you to use as starting points for customizing your
stations' sound. A "preset" is simply a large table of values representing all of the control values for every
control listed in the menu tree. When you Choose a preset, the control values are loaded into the DSP
structure, reconfiguring the Omnia-6fm’s processing.
Omnia/Telos does not warrant in any way that these presets are de facto standards for the format names
that we used when we designed them. The factory presets were created as starting points, typical of the on-
air sound that might be typical with such format names, but they are not engraved in stone! For instance,
the technical sound of CHR stations usually varies from market to market, even though the overall playlist
doesn't. Therefore, you should never assume that because we have a preset name that matches your
format,
that it is the best preset for your format in your market
.
For example, if your station is running an Oldies format, you may want to start with the ROCKnROLL
preset instead of the SOLIDGOLD preset. That’s OK! Start with the preset that sounds the closest to the
sound you are looking for. In some markets, our factory presets may sound too strong or aggressive. In
other markets, they might not be aggressive enough. The factory presets in our previous Omnia product
were judged by our customers to be about in the middle of the playing field with respect to where they
needed to be to be good starting points.
Always rely on our factory presets to get you started. Then, once you find the preset that most closely
matches the sound you're after, you can customize more to your liking. All Omnia6-fm's leave the factory
with the same presets. They can be used as-is, or be excellent starting points for tailoring the sound of your
Omnia for a specific requirement. All of the parameters belonging to a preset can be edited using the
Process Menu to obtain the sound you desire. Your edited preset is then saved to the PC Card under a name
you choose, and can be reselected at any time just like the factory presets. Editing presets is covered in
detail in Parameter Editing below.
