for each band. These compressor/limiters also offer user-adjustable interband
coupling, allowing the user to operate them anywhere from quasi-wideband to
fully independent.

A look-ahead peak limiter with advanced, proprietary distortion reduction algo-
rithms.
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
L
ESS
-M
ORE
, which is a one-knob provision for turning the amount of processing up
or down.
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
IMITER
A
TTACK
controls) simultaneously.
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.
a) If you are not mastering for a Dolby Digital medium (like DVD), defeat
OPTIMOD-PC’s Dialnorm processing by setting the
D
IALNORM
O
UTPUT
control
to O
FF
in the C
ONFIGURATION
page of OPTIMOD-PC’s I/O Mixer.
b) If you are mastering for a Dolby Digital medium, use OPTIMOD-PC’s
D
IALNORM
O
UTPUT
control to specify the OPTIMOD-PC output you will be
using to record from.
c) Set OPTIMOD-PC’s
D
IALNORM
R
EFERENCE
value to match the Dialnorm value
to be authored into the medium’s Dolby Digital metadata. (Refer to step 6
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
OFT
K
NEE
pre-
set. If you are going to use five-band processing, recall the
5B S
OFT
K
NEE
preset. If you want to do look-ahead peak limiting without any other dy-
namics processing, recall the
L
OOK
-A
HEAD
L
IMITER
preset. See page 3-24 for
a description of these presets.
