the trade-offs involved in optimizing one parameter (such as loudness) at the expense of
others (such as distortion or excessive density).
Never lose sight of the fact that, while the listener can easily control loudness, he or she
cannot make a distorted signal clean again. If such excessive processing is permitted to
audibly degrade the sound of the original program material, the signal is irrevocably con-
taminated and the original quality can never be recovered.
Customizing the 6200’s Sound
The subjective setup controls on the 6200 give you the flexibility to customize your sta-
tion’s sound. But, as with any audio processing system, proper adjustment of these con-
trols consists of balancing the trade-offs between loudness, density, and audible distor-
tion. The following pages provide the information you need to adjust the 6200 controls
to suit your format, taste, and competitive situation.
When you start with one of our Factory Presets, there are two levels of subjective ad-
justment available to you to let you customize the Factory Preset to your requirements:
LESS-MORE
and
FULL CONTROL
Less-More
The single LESS-MORE control changes many different subjective setup control settings
simultaneously according to a table that we have created in the 6200’s permanent ROM
(Read-Only Memory). In this table are sets of subjective setup control settings that pro-
vide, in our opinion, the most favorable trade-off between loudness, density and audible
distortion for a given amount of processing. We believe that most 6200 users will never
need to go beyond the
LESS-MORE
level of control, because the combinations of subjec-
tive setup control settings produced by this control have been optimized by Orban’s au-
dio processing experts on the basis of years of experience designing audio processing,
and upon hundred of hours of listening tests.
The LESS-MORE control has a different effect in the “radio” presets than it does in the
“television” 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
“television” presets (except for those few based on “radio” presets), the
LESS-MORE
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 increase. Because of the 6200’s sophisticated gating cir-
cuits, 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 LESS-MORE setting is purposely de-
signed to cause unpleasant distortion and processing artifacts! This helps assure you that
you have chosen the optimum setting of the
LESS-MORE control, because turning the
control up to this point will cause the sound quality to become obviously unacceptable.
