Equalizer Controls - Orban OPTIMOD-PC 1101 Operating Manual

3-35
OPTIMOD-PC OPERATION
Like its two-band counterpart, this preset is sensitive to input levels because its com-
pression ratio is finite. It also fully exploits the Loudness Controller, which usually
shows slight gain reduction with dialog at normal levels.
TV 5B-DRAMA COUPLD (TV Five-Band Drama Coupled): is similar to TV 5B D
RAMA
but uses more interband band coupling in the five-band compressor and a slower
multiband compressor release time so it performs less automatic re-equalization of
the program material. This is an alternative to TV 2B D that de-esses more ef-
RAMA
fectively.
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 un-
predictable. It also automatically re-equalizes substandard audio (which is quite
common in live news broadcasts). The dynamic single-ended noise reduction is
turned on.
TV 5B-SPORTS (TV Five-Band Sports): is similar to TV 5B-N , except the AGC re-
EWS
lease time is slower to resist pumping up crowd noise.
TV 5B-OPTICAL FILM (TV Five-Band Optical Film): is designed to make the best of
the low-quality audio provided with optical film sound tracks (particularly 16mm).
The gate threshold is quite high to avoid pumping up hiss, thumps, and other opti-
cal artifacts. The threshold of the single-ended dynamic noise reduction system is
also high so that this system can reduce artifacts as far as possible. Release times are
slow, because we assumed that material encoded on optical film has already been
carefully level-controlled to accommodate the very limited dynamic range of the
medium, so little gain riding is therefore required from the 1101.

Equalizer Controls

The table summarizes the equalization controls available for the Five-Band structure.
Except for B and DJ B , these equalization controls are common to both
RILLIANCE ASS
the Two-Band and Five-Band structures. The equalizer is located between the AGC
and five-band compressor sections of both structures.
Any equalization that you set will be automatically stored in any User Preset that
you create and save. For example, you can use a User Preset to combine an unmodi-
fied Factory Programming Preset with your custom equalization. Of course, you can
also modify the Factory Preset (with Basic or Advanced Modify) before you create
your User Preset.
In general, you should be conservative when equalizing modern, well-recorded pro-
gram material. This is particularly true with general-purpose video programming.
Except for B , most of the factory presets use less than 3 dB of equalization.
