The Two-Band Structure’s Full and Advanced Setup Controls
The tables below show a summary of the Two-Band controls in the dynamics section.
AGC, Equalizer, Stereo Enhancer, and Clipper controls are common to both Two-
Band and Five-Band structures and are described in the pages above.
Some of the Two-Band controls are common to the Full Modify and Advanced Mod-
ify screens, with additional Two-Band controls available in the Advanced Modify
screen. (Note that “advanced” controls are accessible only from 1100 PC Remote
software.)
2B DRIVE control adjusts signal level going into the two-band compressor, and
therefore controls the density of output audio by determining the amount of gain
reduction in the two-band compressor. The resulting sound texture can be open and
transparent, solid and dense, or somewhere in between. The range is 0 to 25dB.
Regardless of the release time setting, we feel that the optimal amount of gain re-
duction in the two-band compressor for popular music and talk formats is 10-15dB.
If less gain reduction is used, loudness can be lost. For classical formats, operating
with 0-10 dB of gain reduction (with the gain riding

) maintains a
sense of dynamic range while still controlling levels effectively. Because OPTIMOD-
PC’s density gently increases between 0 and 10 dB of compression, 10 dB of com-
pression sounds very natural, even on classical music.
2B REL (“2B Release”) control determines how fast the two-band compressor re-
leases (and therefore how quickly loudness increases) when the level of the program
material decreases. This release time only applies when the silence gate does not
