quency response as "allpass," while adding 4 ms of delay to the processing. Most 2-
band presets use the delay-line derived phase-linear crossover configuration.
The 2-band structure contains a defeatable CBS Loudness Controller algorithm,
which is mainly useful in sound-for-picture-oriented applications. The CBS Loudness
Controller controls the loudness of most commercials well enough to eliminate
viewer annoyance in sound-for-picture applications. It works by constantly monitor-
ing the subjective loudness of the 6300's output. When subjective loudness would
otherwise exceed a preset threshold, the Loudness Controller enhances the normal
gain control produced by the processing with further gain reduction, preventing
loudness from exceeding the threshold. The user can adjust this threshold from the
FULL CONTROL screen of any 2-band preset. The edited preset can then be saved as
a user preset.
The Loudness Controller may reduce the dramatic effect of certain sounds in enter-
tainment programming, like gunshots, explosions, or screeching tires. Operators may
therefore want to turn the Loudness Controller on during commercial breaks and
off during normal programming. All sound-for-picture-oriented 2-band presets have
the Loudness Controller on except for preset 2B GEN PUR NO LC. The easiest way to
turn the Loudness Controller off is to recall this preset. You may also create a User
Preset with the Loudness Controller turned off.
Radio-oriented 2-band presets all have the Loudness Controlled turned
off.
The 5-band structure does not have extra loudness control because its
multiband processing tends to automatically re-equalize and condition
program material to control loudness variations. This is true in both
sound-for-picture and radio-oriented applications.
Factory Programming Presets are our "factory recommended settings" for various
program formats or types. The Factory Programming Presets are starting points to
help you get on the air quickly without having to understand anything about ad-
justing the 6300's sound.
You can easily edit any of these presets with the L
trade-off between loudness and distortion according to the needs of your format,
although this is often unnecessary. It is OK to use unmodified factory presets on the
air. These represent the best efforts of some very experienced transmission process-
ing sound designers. We are sometimes asked about unpublished "programming se-
crets" for Optimods. In fact, there are no "secrets" that we withhold from users. This
manual reveals our "secrets" and the presets embody all of our craft as processing
experts. The presets are editable because other sound designers may have different
preferences from ours, not because the presets are somehow mediocre or improv-
able by those with special, arcane knowledge that we withhold from most of our
customers.
Start with one of these presets. Spend some time listening critically to your sound.
