OPERATION ORBAN MODEL 8600Si
LOUD-PUNCHY
is the quietest of the “loud” preset family. It is designed for a
bright, sizzling top end and very punchy lows. It is a good choice for stations that
feel that the
LOUD-HOT
presets are too aggressive, but that think that the
ROCK
presets are insufficiently loud for their market position.
LOUD-BIG
compromises between
LOUD-HOT
and
LOUD-HOT+BASS
. It uses a 12
dB/octave bass equalizer slope to achieve punchy bass that still has enough mid-bass
boost to help smaller radios.
LOUD-FAT
has dramatic punch on percussive material and a very fat-sounding low
end, plus outstandingly effective distortion control. It avoids overt bass distortion
despite the full bass sound. It is slightly quieter than the loudest of the “loud” pre-
set family.
NEWS-TALK: This preset is quite different from the others. It is based on the fast
multiband release time setting, so it can quickly perform automatic equalization of
substandard program material, including telephone. It is very useful for creating a
uniform, intelligible sound from widely varying source material, particularly source
material that is “hot from the field” with uncontrolled quality. It extensively exploits
distortion control to achieve a very clean, highly compressed, but unclipped sound
quality.
SPORTS: Similar to
NEWS-TALK
except the AGC Release (AGC Release Time) is slow-
er and the Gate Thresh (Gate Threshold) is higher. This recognizes that most sports
programming has very low signal-to-noise ratio due to crowd noise and other on-
field sounds, so the preset does not pump this up as the NEWS-TALK preset would
tend to do.
ROCK, ROCK MX: We have included all of the 8500-style
ROCK
presets and have
made MX versions of
ROCK-MEDIUM, ROCK-SOFT,
and
ROCK-SMOOTH,
which are
cleaner and punchier than their 8500-style counterparts.
ROCK-SOFT MX
and
ROCK-SMOOTH MX
are intentionally tuned for a smooth, mellow high frequency
balance, which can complement female-skewing formats
.
ROCK-DENSE
,
ROCK-MEDIUM
, and
ROCK-OPEN
provide a bright high end and
punchy low end (although not as exaggerated as the
URBAN
presets). A midrange
boost provides enough presence energy to ensure that vocals stand out. A modest
amount of high frequency coupling (determined by the Band Clipping 3 > 4 setting)
allows reasonable amounts of automatic HF equalization (to correct dull program
material), while still preventing exaggerated frequency balances and excessive HF
density. Dense, medium, and open refer to the compression density, which is deter-
mined by the release time settings in the AGC and multiband limiter sections.
These presets are appropriate for general rock and contemporary programming. All
of these presets have distortion control implemented at their nominal levels of
L
ESS
-
M
ORE
to ensure clean speech. At high
L
ESS
-M
ORE
levels the distortion control may be
relaxed somewhat to increase bass punch.
ROCK-LIGHT
has an open sound with little audible compression and less brightness
than the first three presets. It is a compromise between
ROCK-OPEN
and
ROCK-
SOFT
.
