Customizing the 6300's Sound

The subjective setup controls on the 6300 give you the flexibility to customize your
station's sound. Nevertheless, as with any audio processing system, proper adjust-
ment of these controls consists of balancing the trade-offs between loudness, den-
sity, and audible distortion. The following pages provide the information you need
to adjust the 6300 controls to suit your format, taste, and competitive situation.
When you start with one of our Factory Presets, there are two levels of subjective
adjustment available to you to let you customize the Factory Preset to your re-
quirements: Basic Modify and Full Modify. A third level, Advanced Modify, is accessi-
ble only from the 6300's PC Remote software.
See page 6-43 for a block diagram of the processing.

Basic Modify

BASIC MODIFY allows you to control three important elements of 6300 processing:
the stereo enhancer, the equalizer, and the dynamics section (multiband compres-
sion, limiting, and clipping). At this level, there is only one control for the dynamics
section: L -M , which changes several different subjective setup control settings
ESS ORE
simultaneously according to a table that we have created in the 6300's permanent
ROM (Read-Only Memory). In this table are sets of subjective setup control settings
that provide, in our opinion, the most favorable trade-off between loudness, den-
sity, and audible distortion for a given amount of processing. We believe that most
6300 users will never need to go beyond the L -M
ESS ORE level of control because the
combinations of subjective setup control settings produced by this control have been
optimized by Orban's audio processing experts on the basis of years of experience
designing audio processing and upon hundred of hours of listening tests.
The L -M
ESS ORE control has a different effect in the "radio" presets than it does in
the "sound-for-picture" presets. In the "radio" presets, the air sound will become
louder as you go from less to more, but (as with any processor) processing artifacts
will increase. In the "sound-for-picture" presets (except for those few based on "ra-
dio" presets), the L -M
ESS ORE control sets the average amount of dynamic range
control provided by the processing. As you go from less to more, the loudness of
loud sounds will stay about the same but the loudness of quieter sounds will in-
crease. Because of the 6300's sophisticated gating circuits, very quiet material like
background sounds, quiet underscoring, hiss, and hum will not be pumped up.
Please note that, in the "radio" presets, the highest L -M
ESS ORE setting is purposely
designed to cause unpleasant distortion and processing artifacts! This helps assure
you that you have chosen the optimum setting of the L -M
ESS ORE control, because
turning the control up to this point will cause the sound quality to become obviously
unacceptable.
You need not (in fact, cannot) create a sound entirely from scratch. All User Presets
are created by modifying Factory Presets, or by further modifying Factory Presets
that have been previously modified with a L -M
ESS ORE adjustment. It is wise to set
