OPTIMOD 6300 DIGITAL

2-band and 5-band compressor/limiters with phase-linear crossovers and power-
ful controls, including attack time, release time, threshold, knee, and ratio for
each band. These compressor/limiters also offer user-adjustable inter-band cou-
pling, 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 -M
, which is a one-knob provision for turning the amount of processing up
ESS ORE
or down.
The following step-by-step procedure is a good method for creating mastering pre-
sets. It assumes that you have already set the processor mixer controls to achieve
normal drive levels.
A) Connect to the 6300 via 6300 PC Remote software. This gives you access to ad-
vanced controls that are not available from the 6300's front panel. These con-
trols are crucial to fine-tuning the 6300 for mastering.
Note that by selecting groups of controls with your computer's mouse,
you can temporarily couple them so you can adjust several bands' con-
trols simultaneously. You can either CTRL-click the controls you wish to
couple or create a selection box (sometimes called a marquee) around
adjacent controls by clicking and dragging. To ungroup controls, click on
any control outside the group.
B) 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
O control to O
UTPUT
b) If you are mastering for a Dolby Digital medium, use the D
R
EFERENCE
which you will record.
c) Set OPTIMOD-PC's D
to be authored into the medium's Dolby Digital metadata. (Refer to step
12.B)a) on page 2-30.)
C) Decide whether you are going to use 2-band or 5-band processing.
2-band processing retains any fixed equalization originally applied to the
program (except for a mild amount of dynamic adjustment to bass below
200 Hz); 5-band processing performs an "automatic re-equalization"
function. Both flavors of processing can be extremely smooth and unob-
trusive. Because the 5-band compressor/limiter offers user-adjustable in-
terband coupling that determines the "discreteness" of the multiband
compression, it is usually the best choice.
 If you are going to use 2-band processing, recall the 2
