EnhancersDeep BassAdds ‘girth’ to the audio by enhancing very low frequencies such as kick drum fundamentals orvery low bass notes that may be present in the input audio program.Phat BassAn Omnia exclusive, Phat Bass adds harmonic overtones to the lower bass frequencies. Theaddition of these overtones causes small speakers to seem to produce bass response that they arenot actually capable of producing because the human brain equates the presence of low frequencyharmonics to the missing fundamentals that the small speaker is unable to reproduce. On systemswith larger speakers, the effect of Phat Bass becomes subtler because the extended frequencyresponse of those systems allows the fundamentals of the low notes to be heard, masking theadded harmonics contributed by Phat Bass. Be careful though, too much Phat Bass boost can leadto excessive gain reduction in the lower AGC bands and may cause muddiness with certainprogram material. A little goes a long way.WarmthThis Warm Bass EQ is a shelf boost at 150 Hz. Warmth EQ compensates for program materialthat is naturally lacking in upper-bass fullness. Be judicious about applying too much, as theresonant frequency of many automobile interiors lies in this frequency range! Also, too much cancause excessive gain reduction in the following 4-Band AGC stage. A little can give a nice, subtlewarmth enhancement to voices and other program material that may otherwise sound too thin.<-ExitClick on this option to return to the Adjust Processing submenu.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 sharethe 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, lettingfaster peaks through to the following limiter stage. It dynamically equalizes the program material to add consistencywhile gently building up density to keep the following peak limiter stages from working too hard. The output ofeach of the 4-Band AGC bands directly feed their corresponding peak limiter stage. The 4-Band Limiter stageoperates on the peak levels of the program material with each band optimized for its frequency range, controllingpeak levels for the following Sensus® and Final Limiter stages.Low DriveAdjusts the amount of gain reduction in the Low Band AGC. Higher numbers result in more driveand because of the increased compression, a more consistent output from the band.Mid DriveAdjusts the amount of gain reduction in the Mid Band AGC. Higher numbers result in more driveand because of the increased compression, a more consistent output from the band.Pres DriveOmniaONE Multicast - Use and Operation Manual – Version 0.9037
