Enhance
Each of the Deep Bass, Phat Bass and
Warmth controls can boost the level up
to 12 dB. Be careful here not to
overdrive the following limiter 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. It
serves to greatly complement the
Omnia-4.5fm’s clear and open high end
to provide a well-balanced, competitive,
CD-like sound that is both powerful on
the dial, as well as pleasing to the ear.
Enhancers Submenu
Deep Bass EQ: For those who demand thunderous bass, the Omnia-4.5 has it! Up to 12 dB of “thunder”
can be added to shake your listener’s walls! This is not a simple bass boost, but a rather sophisticated
concept that takes into consideration the time alignment of the low frequencies as they pass through the
entire Omnia system. It allows a loud
, clean low end, with absolutely no sacrifice to the overall loudness of
your signal. We won't tell you where the control is in the signal chain. But we will tell you that 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. A little of this effect goes a long way so be careful not to apply too much boost.
Be sure to listen on several different types of radios to arrive at a setting that works best for all of them.
Warmth EQ: The Warm Bass parameter in the Enhance section of the Process submenu is a shelf boost at
150 Hz. Warmth EQ compensates for program material that is naturally lacking in upper-bass punch. Be
judicious about applying too much, as the resonant frequency of most automobile interiors lies in this
frequency range!
Stereo EXP: The Omnia4.5-fm contains an optional
intelligent DSP-based stereo enhancement tool that
enhances the stereo soundfield without causing unnatural "hole in the middle" imaging or exaggerated
multipath when activated. Program audio previously lacking in stereo width will have noticeably increased
ambiance and dimension when the Stereo EXP is active. Vocals will stay up-front and the sonic details of
musical instruments are heard with an apparent slight loudness increase when listening in stereo.
The Stereo EXP control, when enabled has a range of 0 (off) to 16 and the amount of dynamic width
