The 2-band Structure's Full and Advanced Setup Controls

The 2-band structure has an open, easy-to-listen-to sound that is similar to the
source material if the source material is of good quality. We recommend using it
when you want to preserve the spectral balance of the source material while not
significantly increasing program density. Hence, it is mainly useful for unobtrusive
gain riding in sound-for-picture applications (where its loudness controller can be
useful) and in fine arts programming.
If you need processing for loudness and/or processing that automatically
corrects spectral balance inconsistency in the source material, we recom-
mend using the 5-band structure instead.
There are several 2-band presets. These are listed in Table 3-2: Radio-Style Presets on
page 3-26.
The Protection presets have the same Intermediate and Advanced Modify controls
available as the 2-band structure and use the same DSP configuration but with the
stereo enhancer, AGC, and equalizer defeated.
Each 2-band Factory Preset has a L
screen) that adjusts loudness. L
controls to optimize the trade-offs between unwanted side effects as processing
levels are decreased or increased.
If you wish, you may adjust the Modify parameters to your own taste. Always start
with L -M
ESS ORE to get as close to your desired sound as possible. Then edit the Mod-
ify parameters using the Basic, Intermediate or Advanced Modify screen, and save
those edits to a User Preset.
The tables below show a summary of the 2-band controls in the dynamics section.
AGC, Equalizer, Stereo Enhancer, and look-ahead limiter controls are common to
both 2-band and 5-band structures and are described in the pages above.
Some of the 2-band controls are common to the Full Modify and Advanced Modify
screens, with additional 2-band controls available in the Advanced Modify screen.
(Note that "advanced" controls are accessible only from 6300 PC Remote software.)
2B DRIVE control adjusts signal level going into the 2-band compressor, determin-
ing the amount of gain reduction in the 2-band compressor.
Regardless of the release time setting, we feel that the optimal amount of gain re-
duction in the 2-band compressor for sound-for-picture applications is 10-15dB. For
fine arts formats, operating with 0-10 dB of gain reduction (with the gain riding
AGC set to O
FF ) maintains a sense of dynamic range while still controlling levels ef-
fectively.
