Input dynamics processing (D zone)
This section deals with assigning compressor and gate dynamics processors using the
controls in the input channel strip’s D zone. There are four compressors available —
corrective, adaptive, creative and vintage — each with the option of hard knee, medium
knee and soft knee (see Appendix A "Application Notes" on page 299). Visual feedback
for both compressor and gate is provided by meters in each input fast strip, the
dashboard screen and just above/below the graph, which gives a representation of the
compressor/gate action.

>> To set up a compressor/limiter
1 Select the desired input channel.
2 In the channel strip, press the quick access button in the comp section (see
Figure 4 “Compressor and gate channel strips” above) to select the input
channel’s compressor processing area.
3 Press ON in the comp section to switch the compressor in.
4 Operate the attack, ratio/range (ratio), release, threshold and make up
control knobs (hold has no effect) to apply processing. See “Compressor” on
page 260. You can set up a limiter by using a high threshold and a steep ratio
(greater than 5:1).
5 Press KNEE to audition the different
algorithms (hard knee, medium knee
and soft knee). The effects on the
signal are shown right.
