Table 3-3: Factory Programming Presets (Video)
The video presets have been named similarly to their counterparts in Orban's
OPTIMOD-TV 8382. The texture of the corresponding OPTIMOD-PC and 8382 presets
is quite similar, although the OPTIMOD-PC presets will usually have a less restricted
high frequency sound because OPTIMOD-PC performs no high frequency limiting
other than that created by gain reduction in Band 5 in the Multiband presets.
TV 2B–GEN PURPOSE (TV Two-Band General Purpose): This preset is designed to
accommodate most dramatic programming, providing gentle gain control that limits
dynamic range to a level that provides the general audience with consistently intel-
ligible 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. TV 2B-G

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.
TV 5B-GEN PUR W/NR (TV Five-Band General Purpose with Noise Reduction): pro-
vides effective dynamic range control and "automatic re-equalization" of most
dramatic material. It applies single-ended noise reduction to the material, which will
reduce unwanted noise like hiss, hum, or stage rumble. However, it will also reduce
ambience. If the program material is carefully produced (as are most contemporary
feature-film soundtracks), you may wish to use TV 5B-G

benefit from "automatic re-equalization," use TV 2B-G

TV 5B-NEWS (TV Five-Band News): rides gain more quickly than the general-
purpose presets. Its AGC release time is faster so it will bring up low-level material
more quickly. It is designed for live news programs where input levels may be quite
unpredictable. It also automatically re-equalizes substandard audio (which is quite
common in live news broadcasts).
