• Reduce the Release time 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.

Making 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 Limiter 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.

Thunder Bass
Omnia-6 has the power to shake the walls with low end! If your source material has it, Omnia-6 will put it
on the air, and with muscle! Making changes to this characteristic is done using the following parameters,
and for maximum effectiveness, in the order listed:
on the air, and with muscle! Making changes to this characteristic is done using the following parameters,
and for maximum effectiveness, in the order listed:
1. In the Enhance Menu, increase the amount of Deep Bass or Phat Bass boost.
2. Increase the drive to the LF Limiters with the appropriate controls in the Limiter XO screen.
3. Speed up the Release times of the LF Limiter sections.
When it comes to processing, moderation is the key! If all of the above steps are utilized in the pursuit of
more bass, then severe low frequency over-enhancement can occur. Excessive bass boost can produce the
illusion that the presence and high frequencies have been lost. They are still there, but are being
acoustically masked by the lower frequencies.

Another concern is the creation of bass-induced intermodulation distortion in the clipper. This artifact
