excessive look-ahead final limiting in that band’s frequency range. We suggest that any changes implemented here
be limited to about 0.5 dB to 0.7 dB of boost maximum. Alternately, a decrease in mix levels can be done in any
desired amount and without fear of final limiter overdrive.
Thunder Bass
Omnia ONE Multicast has the power to shake the walls with low end! If your source material has it, Omnia ONE
Multicast can expose that deep bass and do it with muscle! Tailoring Thunder Bass for more dominance is simple,
and is done by adjusting the following parameters and in the order listed:
1.
Increase the amount of
Bass
boost in the
Enhance
section.
2.
Increase the
Drive
to
Low Frequency Limiter.
3. Increase
the
Release
setting in the
Low Frequency Limiter.
4.
Increase the
Drive
to the
Bass Clipper.
Just as in the section on ‘overdoing’ processing, again moderation is the key. If all of the above changes are made in
unison there is a possibility of severe low frequency buildup. This would unbalance the audio spectrum and produce
the illusion of “lost” presence and high frequencies.
Generally, an increase in the Bass boost alone will provide a sufficient enhancement to the low end. Bass
adjustments should typically be done after selecting the preset you wish to use and the low pass filter that is
appropriate for the codec to be used.
Coded Audio Considerations
Adjusting processing for coded audio is different than conventional radio. While many of the dynamics functions are
the same, i.e. compression, limiting, EQ, etc, please consider that the audio processor is a tool to improve the
performance of the codec. This is especially true at lower bitrates. When making processing adjustments, try to
avoid building too much density in the presence and high frequency ranges. Density in this spectra cause codec
efficiency to become reduced and artifacts increased.
Even though Sensus
technology is applied downstream from the main processing and will improve system
performance, remember that the processor is a sum of its collective
dynamics
parts and the result will be based on
the cumulative effect of all of the settings. When adjustments are being made pay particular attention to program
content that segues from music to voice and back again. If everything is working properly the vocal quality should
not change due to the coding process. If this is noticed, try reducing the Sensus
function value by one adjustment
click and then re-evaluate.
