APPENDIX 12
Threshold Linking
Within the Multi-band Dynamics Processor itself, the Threshold controls of
the Gate, Expander, and Compressor may also be linked. There is a lock icon
next to the Threshold control label in each band, for the Gate, Expander, and
Compressor control sections.
Activating this Threshold Link lock in any band simultaneously locks together
the thresholds of the Gate, Expander, and Compressor in that band. The way
this works is that when the Threshold Link is activated, the Gate Threshold
no longer indicates the absolute threshold level, but instead indicates the
level of the Gate threshold below the Expander threshold. Similarly, the
Expander Threshold no longer indicates the absolute threshold level, but
instead indicates the level of the Expander Threshold below the Compressor
Threshold.
When the thresholds of the Gate, Expander, and Compressor are linked in
this manner, the user can manipulate all three thresholds together, moving
a constant dynamics curve over a range of input levels. As can be seen from
each band’s Gate/Expander/Compression IO curve, with the thresholds
linked the user can zoom in on the sweet spot of the dynamic range of that
band. The compressor will attenuate the input level, while the expander can
decrease or increase signal levels at a preset level below the compressor
level, and  nally the gate can reduce signal levels at a preset level below the
expander level.
