OPERATION

Equalizer Controls

These presets defeat the AGC and do all gain riding with the 2-band compressor,
which is set for reverse exponential release. This release characteristic does not sig-
nificantly increase the density of material whose level is well controlled while still
performing fast correction of levels that are too low.
TV 5B-GEN PUR W/NR (TV 5-band General Purpose with Noise Reduction): provides
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 ambi-
ence. If the program material is carefully produced (as are most contemporary fea-
ture-film soundtracks), you may wish to use TV 5B-G
ply noise reduction), or, if the material is so well produced that it would not benefit
from "automatic re-equalization," use TV 2B-G
TV 5B-GEN PURPOSE (TV 5-band General Purpose without Noise Reduction): is

tion system is off.
TV 5B-NEWS (TV 5-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).
TV 5B-SPORTS (TV 5-band Sports): is similar to TV 5B-N
time is slower to resist pumping up crowd noise.
TV 5B-OPTICAL FILM (TV 5-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 optical ar-
tifacts. 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 6300.

multiband 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
