FOLK TRADITIONAL: FOLK TRADITIONAL is derived from the POP-MEDIUM
source preset. It is a more conservative preset designed for a mellow, open high end.
There is substantial high frequency coupling (determined by the
B3>B4 CPL and B4>B5
CPL
settings) to ensure that the high frequencies do not become dense. This is an ideal
preset for formats designed primarily for women listeners (who, by and large, dislike
hyped treble) or for any preset designed for long time-spent-listening formats because of
its open, clean sound, which leads to very low listener fatigue.
NEWS/TALK: This preset is quite different from the others above. It is based on the
fast
multi-band release time setting, so it can quickly perform automatic equalization of
substandard program material, including telephone. It is very useful for creating a uni-
form, intelligible sound from widely varying source material, particularly source mate-
rial that is “hot from the field” with uncontrolled quality.
SPORTS: Similar to
NEWS/TALK
except the
AGC REL
(AGC Release Time) is slower
and the GATE THR (Gate Threshold) is higher. This recognizes that most sports pro-
gramming 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.

Table 3-2: Factory Programming Presets (Television)
TV 2B-GEN PURPOSE (TV Two-Band General Purpose): This preset is designed to
accommodate most dramatic programming, providing gentle gain control that limits dy-
namic 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 oper-
ating manual. This preset retains the spectral balance of its input as much as possible.
The loudness controller prevents irritating loudness excursions but can also reduce the
impact of sound effects in dramatic programming. A station may therefore wish to acti-
vate this preset during commercial breaks, game shows, and the like, and activate
TV 2B-
GP NO LC (TV Two-Band General Purpose; no Loudness Controller) for dramatic pro-
gramming .
TV 2B-GEN PURPOSE
is usually not the best choice for live news, sports, or
films with optical soundtracks. The Five-Band presets (see below) can automatically
equalize such program material when its spectral balance is inappropriate and can also
apply single-ended dynamic noise reduction.
