5.3.1.3 Turn up the Clipper control.
5.3.1.4 A combination of all of the above!
Sounds crazy, but it’s true! In this situation, resist the temptation to make too many
changes at once. When that occurs, it becomes difficult to determine why, or why not, an
adjustment made sense. Let one specific area at a time be the main focus. After that area
is satisfactory, then move the focus to another area, as needed.
5.3.2 What you can do to get more detail and clarity
The simplest approach is to try a less aggressive preset. But, if you are really happy with
the general character of the current preset and just want a little more detail, or you can’t
find a preset with the right loudness/cleanness compromise, try the following suggestions
on where to begin to make changes. Try them in the order described in sections 5.3.2.1 to
5.3.2.3, which is basically just reversing the procedures listed above in 5.3.1.
5.3.2.1 Turn down the Clipper control.
5.3.2.2 Back off on the influence of the Limiter stages:
• Reduce the amount of Drive.
• Reduce the Release time to slow down recovery.
• Raise the threshold of the Hold function.
5.3.2.3 Ease up on the Wideband-AGC sections:
• Reduce the Processing Drive to the Wideband-AGC.
• Reduce the Drive to the Wideband-AGC.
• Reduce the Release time to operate slower.
Backing off the clipping sections first will allow the processing to retain a level of
loudness while restoring quality. 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, a change in the Clipper amount 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.
