tween loudness and distortion according to the needs of the format. The presets can
be further edited with Basic, Full Modify, or Advanced Modify to fine-tune them.
The controls in the Five-Band structure give you the flexibility to customize your sta-
tion sound. Nevertheless, as with any audio processing system, proper adjustment of
these controls requires proper balancing of the trade-offs between loudness, den-
sity, and audible distortion. The following provides the information you need to ad-
just the Five-Band structure controls to suit your format, taste, and competitive
situation.
The tables below show the Multiband and Band Mix controls in the dynamics sec-
tion. 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
above.
Except as noted, these controls affect both the analog and HD processing
chains.
MB Drive control adjusts the signal level going into the multiband compressor and
therefore determines the average amount of gain reduction in the multiband com-
pressor. Range is 25 dB.

with slower multiband release times, the multiband compressor produces an open,
re-equalized sound. The multiband compressor can increase audio density when op-
erated 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, density also
increases when you increase the drive level into the multiband compressor because
