priate and can apply single-ended dynamic noise reduction.
2B–GEN PURPOSE NO LC (Two-Band General Purpose with Loudness Controller De-
feated) is the same as 2B-GEN PURPOSE except that the Loudness Controller is de-
feated. Defeating the Loudness Controller is sometimes desirable for entertainment
programming that uses loud effects (gunshots, screeching tires, and the like) for
dramatic effect. This preset could be put on-air (by automation) during entertain-
ment programming while
2B-G

P
URPOSE
(which has loudness control) could be
used during commercials and promos to reduce audience irritation, thus reducing
the inclination of the audience to mute the audio or to tune out altogether during
these segments.
JPN 2B PROCESSED is the same as
2B-GEN PURP NO LC
except that the
MB L

control is set to “0 .” This ensures that test tone levels will not
change when the processing is switched between

and

modes,
facilitating alignment with tones.
2B–FINE ARTS (Two-Band Fine Arts) is identical to
2B-G
EN
P
URPOSE
except that it
rides gain more slowly than the general-purpose presets.
2B–NEWS (Two-Band Live News) rides gain more quickly than the general-purpose
presets. Its gate threshold is lower, so it will bring up low-level input material more
quickly. It is designed for live news programs where input levels may be quite un-
predictable. Being a Two-Band preset, it does not automatically re-equalize substan-
dard audio (which is quite common in live news broadcasts). You may therefore pre-
fer the Five-Band Live News preset (
5B-N
EWS
) .
2B–SPORTS (Two-Band Live Sports): is similar to
2B–N
EWS
except the release time is
slower to resist pumping up crowd noise.
5B-GEN PUR W/NR (Five-Band General Purpose with Noise Reduction): provides ef-
fective 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
5B-G
EN
P
URPOSE
(which does not apply
noise reduction), or, if the material is so well produced that it would not benefit
from “automatic re-equalization,” to use
2B-G
EN
P
URPOSE
.
5B-GEN PURPOSE (Five-Band General Purpose without Noise Reduction): is identical
to 5B-G
EN
P
UR
W/NR except that the single-ended dynamic noise reduction system is
off.
5B-NEWS (Five-Band News): rides gain more quickly than the general-purpose pre-
sets. Its AGC release time is faster so it will bring up low-level material more quickly.
It is designed for live news programs, whose input levels may be quite unpredict-
able. It also automatically re-equalizes substandard audio (which is quite common in
live news broadcasts).
5B-SPORTS (Five-Band Sports): is similar to
5B-N
EWS
, except the AGC release time is
slower to resist pumping up crowd noise.
