16All three options will provide noticeable change in EQ. We suggest you use the first two listed options.In either case, an EQ change is still followed by a dynamically controlled stage. Therefore any excessive EQ changecan be 'undone' by the subsequent AGC or Limiter.The last option, adjusting the Mixer, is designed to provide a final minor trim to the spectrum. If you've noticed thatwe calibrated these controls in 0.10 dB steps, then you know what we mean when we say these controls are for finetrim!Since this stage is after all of the dynamic AGC and Limiting, a radical change in level in the Mixer will result inadditional and possibly excessive final limiting or clipping distortion of audio in that band. We suggest that changesimplemented here be limited to no more than about 1.0 dB. Naturally, the decrease in mix level can be done to anydesired amount.Thunder BassOmnia.ONE FM has the power to shake the walls with low end! If your source material has it, Omnia.ONE FM canexpose that deep bass and do it with muscle! Tailoring Thunder Bass for more dominance is simple, and is done byadjusting the following parameters and in the order listed:1. Increase the amount of Bass boost in the Enhancers section.2. Increase the Drive to the 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 inunison there is a possibility of severe low frequency buildup. This would unbalance the audio spectrum and producethe illusion of “lost” presence and high frequencies.Generally, an increase in the Bass boost alone will provide a sufficient enhancement to the low end. Bassadjustments should typically be done after selecting the preset you wish to use.AM StyleWelcome to the OMNIA.ONE AM!Don’t let the small single-rack sized package fool you! Omnia.ONE’s new hardware platform allows us to packmore power in its single rack space than the original Omnia had in three!This chapter explains generally how to alter the sound of the Omnia.ONE AM using the factory presets, and ifdesired, using the controls explained in the Adjust Processing section of Chapter 4, to alter those presets and createcustom user presets.Using Omnia.ONE AM with Early PWM TransmittersCertain PWM (Pulse Width Modulation) transmitter designs may exhibit a condition that can be exaggerated by theextremely dense output of the Omnia. This condition is often referred to as the “cliff effect”.These transmitters have a hard time dealing with linear response to high negative modulation levels and may show arunaway condition when called upon to produce heavy negative modulation approaching 100 percent.This effect can be seen by applying a steady 1 kHz tone to the transmitter at slightly less than 95 percent negativemodulation. Observe the modulation monitor closely as you slowly advance the modulation level to 100 percent.
