The Five-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 Clipper controls are common to
both the Two-Band and Five-Band structures and are discussed in their own sections
in Section 3. (Note that "advanced" controls are accessible only from 8300 PC Re-
mote 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 25 dB.

lightly with slower multiband release times, the multiband compressor produces an
open, re-equalized sound. The multiband compressor can increase audio density
when operated at faster release times because it acts increasingly like a fast limiter
(not a compressor) as the release time is shortened. With faster release times, den-
sity also increases when you increase the drive level into the multiband compressor
because these faster release times produce more limiting action. Increasing density
can make 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 negative subjective side
effects of excessive density when setting controls that affect the density of the proc-
essed sound.
The M D interacts with the M

lease time settings, increasing the M
Instead, the primary danger is that the excessive drive will cause noise to be in-
creased excessively when the program material becomes quiet.
You can minimize this effect by carefully setting the M
trol to "freeze" the gain when the input gets quiet and/or by activating the single-
