OPERATION ORBAN MODEL 6300
prefer the more open sound of the 5-band compressor without additional loudness
control.
The loudness controller sidechain receives the output of the MB Limiter. Hence, the
loudness controller responds accurately to all 6300 audio processing except look-
ahead limiting, which is a peak limiting process whose gain reduction does not sig-
nificantly affect subject loudness.
If you feel that the Loudness Controller is not controlling the loudness of commer-
cials or other subjectively loud program material sufficiently well, you may wish to
set the threshold lower, forcing the Loudness Controller to do more work. Con-
versely, if the loudness controller is doing more gain reduction that you would like,
you can set the L
OUDNESS THRESHOLD control higher.
Note that the Loudness Controller operates with reference to an absolute subjective
loudness threshold that does not adapt to program context. This means that if there
is a transition between very quiet program material (like footfalls through rustling
leaves) and a commercial, the commercial may still seem offensively loud even
though the Loudness Controller is controlling its loudness correctly with reference to
other sounds that reach full-scale loudness. Philosophically, this is inevitable; the
Loudness Controller cannot reduce the level of the commercial to the level of rus-
tling leaves without destroying the effectiveness of the commercial and angering
the sponsor!

PARENT PRESET and Less-More INDEX are read-only fields.
The 6300's front-panel LCD display does not show all of the parameters in a given
User Preset; only the PC Remote software can display the Advanced Controls that set
all the parameters. P P
ARENT RESET shows the preset that was edited to produce the
current User Preset. The L -M I
shows the Parent Preset's Less-More set-

ting when it was edited. This information is needed because two different User Pre-
sets can appear to be the same when you view only the parameters that the 6300's
front panel exposes.
Please note that if a User Preset was created by in the PC Remote software by edit-
ing Advanced controls, an asterisk will appear in front of the displayed parent pre-
set. This asterisk means that you cannot duplicate a given user preset by starting
with its parent preset and then setting a target 6300's front panel controls to corre-
spond to the user preset you want to duplicate. The only way to duplicate such a
user preset accurately is via the PC Remote software's backup and restore features,
or by opening the preset in the PC Remote software and manually duplicating each
control setting you see.
