OPERATION ORBAN MODEL 8600
•
Presets without MX, LL, or UL designators in their names have “optimum delay”
for an 8500-style preset. This delay is approximately 18 ms delay (5-band) and 21
ms delay (2-band).
PROTECTION-0DB :

ROTECTION
-0
DB
is a two-band preset with a high amount of
band coupling. It is intended for use below threshold most of the time (i.e., with 0
dB gain reduction), to provide protection limiting in the highest quality applications
such as serious classical music intended for an attentive audience. Its

con-
trol determines the normal amount of gain reduction but does not increase distor-
tion or other processing artifacts when turned up.
CLASSICAL, CLASSICAL MX : The 8600 offers 8500-style and MX variants of all clas-
sical presets. The MX versions provide less preemphasis limiting, lower distortion,
and higher transient impact than the non-MX versions and are therefore recom-
mended if their longer delay is acceptable.
As their names imply, the
CLASSICAL 5-BAND
and
CLASSICAL 2-BAND
presets are
optimized for classical music, gracefully handling recordings with very wide dynamic
range and sudden shifts in dynamics. The Five-Band version uses heavy inter-band
coupling to prevent large amounts of automatic re-equalization, which could oth-
erwise cause unnatural stridency and brightness in strings and horns and which
could pump up very low frequency rumble in live recording venues.
The Five-Band preset defeats the AGC, using only the multiband compressor for gain
reduction. It also defeats phase rotation to ensure the most transparent Five-Band
sound available.
Even more transparent, “purist” classical processing is available from the
CLASSICAL 2-BAND
preset, which is phase-linear and which preserves the spectral
balance of the original material as much as possible. However, if you need a bit
more automatic re-equalization than the
CLASSICAL 2-BAND
preset provides, use
the
CLASSICAL 5-BAND
preset.
CLASSICAL-5B+AGC
uses the AGC set for 2:1 compression ratio. Because of the
AGC, it affects more of the total dynamic range of the recording than does the
CLASSICAL-5 BAND
preset. However, the AGC provides extremely smooth and un-
obtrusive compression because of the gentle ratio and window gating. This preset
uses the Five-Band compressor very lightly with a fast release time as a peak limiter.
The AGC does almost all of the compression.
There is also a corresponding two-band preset called
CLASSICAL-2B+AGC
.
COUNTRY: The
COUNTRY-MEDIUM
preset uses the
ROCK-SMOOTH
source preset. It
has a gentle bass lift and a mellow, easy-to-listen-to high end, along with enough
presence energy to help vocals to stand out. The
COUNTRY-LIGHT
preset uses the
ROCK-LIGHT
source preset. Modern country stations might also find
ROCK-MEDIUM
or
ROCK-OPEN
useful if they want a brighter, more up-front sound.
While there are no specifically named Country MX presets, we suggest that modern
country stations experiment with
ROCK-MEDIUM MX, ROCK-SMOOTH MX, ROCK-
