Gate
When gate is set to ON, it will freeze the gain at the last level of processing action that occurred before
the audio signal fell below the threshold of operation. This control helps to minimize “pumping” and the
increase of background noise during pauses in programming.
Bass
The bass section contains the Bass EQ controls. In the Omnia F/XE’s unique signal processing architecture,
these controls are placed in their optimal position — just before the multiband processor sections. Each of
the
Deep Bass and Phat Bass controls can boost the level up to 12 dB. Be careful here not to overdrive the
following sections or over emphasize these lower frequency ranges. When used properly this specialized
low frequency enhancement tools can deliver the thunderous bass and warmth that the Omnia is known for,
and it can do so without making the sound muddy.
Deep Bass EQ
In order to achieve thunderous bass, the Omnia F/XE has a deep base setting. Up to 12 dB of “thunder” can
be added to the audio. This is not a simple bass boost, but a rather sophisticated concept that takes into con-
sideration the time alignment of the low frequencies as they pass through the entire system. It allows a loud,
clean low end, with absolutely no sacrifice to the overall loudness of your signal. The deep bass function is a
shelf boost at 85 Hz, utilizing a phase compensated 12dB/octave slope to emulate the EQ function.
Phat Bass EQ
Phat Bass is a unique enhancement that adds filtered harmonics of the lower registers to the upper bass
frequencies. The algorithm extracts information contained in the initial attack to do its work, and low
frequency texture is therefore emphasized. Older recordings sound fuller (or phatter) with the added
illusion of loudness. Phat Bass EQ also helps radios with small speakers sound like they have more bass than
they actually do.
X-Over
Phase Linear, Time Aligned Crossover
Most multiband audio processors make a compromise in the crossover area in order to provide a flat
dynamic frequency response. This is done to avoid audible peaks or dips in the recombined frequency
response as the individual band gains change during processing. In an effort to minimize this problem, most
processors use a fixed phase-offset in the crossovers. While such treatment helps to minimize frequency
response peaks and dips, it also results in a loss of phase linearity, increasing “smearing’, and reducing
musical clarity.
