coupling, allowing the user to operate them anywhere from quasi-wideband to
fully independent.

You cannot create a user preset "from scratch"; you must create it by modifying an
existing preset, factory or user. Each preset has an "easy adjustment" facility called
, which is a one-knob provision for turning the amount of processing up

Systematically, the following is a good method for creating mastering presets. It as-
sumes that you have already set the processor mixer controls to achieve normal drive
levels.
Note that by drawing a marquee around several controls by clicking and dragging
with your computer's mouse, you can temporarily couple them so you can adjust
several bands' controls (for example, the L
The coupling will remain active until you click outside the area that the marquee
encloses.
A) Set Dialnorm processing for the medium for which you are mastering.

c) Set OPTIMOD-PC's D

on page 2-26.)
B) Decide whether you are going to use two-band or five-band processing.
Two-band processing retains any fixed equalization originally applied to
the program (except for a mild amount of dynamic adjustment to bass
below 200 Hz); five-band processing performs an "automatic re-
equalization" function. Both flavors of processing can be extremely
smooth and unobtrusive. Because the five-band compressor/limiter offers
user-adjustable interband coupling that determines the "discreteness" of
the multiband compression, it is usually the best choice.
If you are going to use two-band processing, recall the 2B S
set. If you are going to use five-band processing, recall the 5B S
preset. If you want to do look-ahead peak limiting without any other dy-
namics processing, recall the L
