Air-Sound Equalization Changes; Thunder Bass - Omnia ONE FM Installation And Operation Manual

Backing off the clipping sections first will allow the processing to retain a level of competitive loudness while
enhancing quality, and the overall dynamic texture will be affected less.
Start with reducing the Clipper amount in 0.5 dB steps. It's surprising how much detail can be restored from just a
small change of 0.5 dB. Continue to reduce it until the loudness just falls off too much and then bring it back up a
little from there.
Generally, changes in the Clipper drives will have the most noticeable effect on quality, but it will also affect the
relative loudness level, too. You'll need to find a "happy medium" that's right for you.

Air-Sound Equalization Changes

Tailoring the shape of the overall audio spectrum can be done in three different sections:
The relative drive settings in the multiband AGC Xover menu.
1.
The relative Drive settings in the individual multiband Limiter menus.
2.
The settings of the multiband limiter Mixer controls.
3.
All 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 change
can 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 that
we calibrated these controls in 0.10 dB steps, then you know what we mean when we say these controls are for fine
trim!
Since this stage is after all of the dynamic AGC and Limiting, a radical change in level in the Mixer will result in
additional and possibly excessive clipping distortion of audio in that band. We suggest that changes implemented
here be limited to no more than about 1.0 dB. Naturally, the decrease in mix level can be done to any desired
amount.

Thunder Bass

OmniaONE FM has the power to shake the walls with low end! If your source material has it, OmniaONE FM can
expose that deep bass and do it with muscle! Tailoring Thunder Bass for more dominance is simple, and is done by
adjusting the following parameters and in the order listed:
1. Increase the amount of Bass boost in the Enhance 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 in
unison there is a possibility of severe low frequency buildup. This would unbalance the audio spectrum and produce
the illusion of "lost" presence and high frequencies.
Generally, an increase in the Bass boost alone will provide a sufficient enhancement to the low end. Bass
adjustments should typically be done after selecting the preset you wish to use.
