The 5-band Structure's Full and Advanced Setup Controls

The tables below summarize the Multiband and Band Mix controls in the dynamics
section. The AGC, Equalizer, Stereo Enhancer, and look-ahead limiter controls are
common to both the 2-band and 5-band structures and are discussed in their own
sections in Section 3. (Note that "advanced" controls are accessible only from 6300
PC Remote software.)
MB DRIVE ("Multiband Drive") control adjusts the signal level going into the multi-
band compressor, and therefore determines the average amount of gain reduction
in the multiband compressor. Range is 25dB.

Used lightly with a slow or medium release time, the 5-band compressor produces
an open, re-equalized sound that is appropriate for most sound-for-picture pro-
gramming. The 5-band compressor can increase audio density when operated at a
fast or medium-fast release because it acts more and more like a fast limiter (not a
compressor) as the release time is shortened. With fast and medium-fast release
times, density also increases when you increase the drive level into the 5-band com-
pressor because these faster release times produce more limiting action. Increasing
density can make loud sounds seem louder, but can also result in an unattractive
busier, flatter, or denser sound. It is very important to be aware of the many nega-
tive subjective side effects of excessive density when setting controls that affect the
density of the processed sound.
Because the 6300's AGC algorithm uses sophisticated window gating, it is preferable
to make the AGC do most of the gain riding (instead of the multiband compressor),
because the AGC can ride gain quickly without adding excessive density to program
material that is already well controlled. Use the multiband compressor lightly, so it
can achieve automatic re-equalization of material that the AGC has already con-
trolled without adding excessive density to the audio or re-equalizing to an unnatu-
ral extent.
