generate a signal of high short-term density. Also, an increase in clipping will further aid this. The effect of the
processing set in this manner is that the audio is consistently loud at all times . . . a wall of sound. The drawback is
that the density can cause listener fatigue and have a negative effect on time spent listening. While Omnia-6 is
designed to minimize listener fatigue, it is capable of generating large amounts of density that could eventually lead
to fatigue. Be careful!
Adding More Detail — When Loudness Isn’t the Last Word
Now that we’ve “squashed the grape,” lets look at what it takes to undo a heavily processed signal. Basically, just
reversing the procedures listed above will do the trick:
1. Reduce the drive to the Clipper/Look Ahead Limiter.
2. Back off on the influence of the Limiter stages:
• Reduce the amount of Drive to each band in the Limiter XO screen.
• Reduce the Release times to slow down recovery.
• Raise the threshold of the Hold function.
3. Ease up on the Wideband-AGC sections:
• Reduce the Drive to the WB AGC and the Multiband AGC bands in the WB and AGC XO screens.
• Reduce the Release times to operate slower.
• Reduce the amount of Make-Up Gain.
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. 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:
1. The relative drive settings in the multiband AGC XO menu. These controls set the drive levels of the
multiband AGC sections.
2. The relative drive settings in the multiband Limiter XO menu. These controls set the drive levels of the
multiband limiters.
3. The settings of the multiband limiter Mixer controls.
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 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.
