OPERATION
ORBAN MODEL 1101
However, if the loudness/density tradeoff is not to your taste, use
L
ESS
-M
ORE
to turn
it down, producing lower loudness with less density.
WMA MUSIC:
This preset is based on
GREGG
SLOW
but has been edited to mini-
mize artifacts in the Windows Media Audio V9 codec when operated at bitrates be-
low 64 kbps. See
WMA NEWS-TALK:

URBAN:
There are two
URBAN
(Rap) presets:
HEAVY
and
LIGHT
. These are similar
to
ROCK-MEDIUM
and
ROCK-OPEN
but with a different bass sound. They use the 3-
pole (18 dB/octave) shape on the bass equalizer.
URBAN-HEAVY
is appropriate for
Urban, Rap, Hip-Hop, Black, R&B, Dance and other similar formats.
URBAN-LIGHT
is
appropriate for light R&B formats. Highly competitive Urban broadcasters might al-
so use
LOUD-HOT+BASS
or
LOUD+SLAM
, modified versions of
LOUD-HOT
that max-
imize bass punch.
Sound for Picture Presets
The sound-for-picture presets come in two variants: TVxxxx for digital transmission
channels using no preemphasis and TVAxxxx for analog FM transmission channels
that use 50
µ
s or 75
µ
s preemphasis. Most of these presets have the CBS Loudness
Controller turned on. It is set so that loudness is constrained to a level consistent
with the active
D
IALNORM
on page 3-14). The
D
IALNORM
value is the same as the “target loudness” as measured by an ITU-R BS.1770-2 loud-
ness meter in units of LKFS (ATSC Rec. A/85) and LUFS (EBU Rec. R128). To comply
with these standards,
D
IALNORM
is customarily set to –24 in the United States and –23
in the EU.
To constrain the reading of a BS.1770-2 loudness meter (included with OPTIMOD-PC)
to a fixed threshold, almost all “TV” presets have the
BS.1770
T
HRESHOLD
control set
to 0
LK.
However, if your organization does not have a strict policy about processing
for the BS.1770 meter, we recommend that you edit your preferred preset by setting
this control anywhere from
+2
to
O
FF
and then saving the result as a User Preset
.
For
a more detailed discussion, see
on page 3-17.
If you wish to use a given preset with the CBS loudness controller turned off, set its
L
OUDNESS
T
HRESH
parameter to
O
FF
and save the result as a User Preset.
TV 2B–GEN PURPOSE
(TV Two-Band General Purpose): This preset accommodates
most dramatic programming (particularly older material), providing gentle gain con-
trol that limits dynamic range to a level that provides the general audience with
consistently intelligible dialog. It sounds very similar to Orban’s analog OPTIMOD-TV
(Model 8182A) when that unit is adjusted for “General” programming according to
the instructions in its operating manual. This preset retains the spectral balance of
its input as much as possible.
