Phat Bass
An Omnia exclusive, Phat Bass adds harmonic overtones to the lower bass frequencies. The
addition of these overtones causes small speakers to seem to produce bass response that they are
not actually capable of producing because the human brain equates the presence of low frequency
harmonics to the missing fundamentals that the small speaker is unable to reproduce. On systems
with larger speakers, the effect of Phat Bass becomes subtler because the extended frequency
response of those systems allows the fundamentals of the low notes to be heard, masking the
added harmonics contributed by Phat Bass. Be careful though, too much Phat Bass boost can lead
to excessive gain reduction in the lower AGC bands and may cause muddiness with certain
program material. A little goes a long way.
Warmth
This Warm Bass EQ is a shelf boost at 150 Hz. Warmth EQ compensates for program material
that is naturally lacking in upper-bass fullness. Be judicious about applying too much, as the
resonant frequency of many automobile interiors lies in this frequency range! Also, too much can
cause excessive gain reduction in the following 4-Band AGC stage. A little can give a nice, subtle
warmth enhancement to voices and other program material that may otherwise sound too thin.

Xover (Crossover)
The crossover splits the audio signal into 4 independent bands to enable optimum processing for the bass (L),
midrange (M), presence (P) and treble (H) frequency ranges. There are two four-band processing stages that share
the same crossover. The crossover points are 180Hz, 1kHz and 3.7kHz.
The first stage is the 4-Band AGC (Automatic Gain Control) stage. This stage operates on the average level, letting
faster peaks through to the following limiter stage. It dynamically equalizes the program material to add consistency
while gently building up density to keep the following peak limiter stages from working too hard. The output of
each of the 4-Band AGC bands directly feed their corresponding peak limiter stage. The 4-Band Limiter stage
operates on the peak levels of the program material with each band optimized for its frequency range.
Low Drive
Adjusts the amount of gain reduction in the Low Band AGC. Higher numbers result in more drive
and because of the increased compression, a more consistent output from the band.
Mid Drive
Adjusts the amount of gain reduction in the Mid Band AGC. Higher numbers result in more drive
and because of the increased compression, a more consistent output from the band.
Pres Drive
Adjusts the amount of gain reduction in the Presence Band AGC. Higher numbers result in more
drive and because of the increased compression, a more consistent output from the band.
Hi Drive
Adjusts the amount of gain reduction in the High Band AGC. Higher numbers result in more drive
and because of the increased compression, a more consistent output from the band.
