Table 3-1: Factory Programming Presets
PROTECTION: PROTECTION is a two-band preset with a high amount of band cou-
pling. It is intended for use below threshold most of the time, to provide protection limit-
ing in the highest quality applications such as serious classical music intended for an at-
tentive audience. Its
Less/More control determines the normal amount of gain reduction
but does not increase distortion or other processing artifacts when turned up.
CLASSICAL:
As their names imply, the CLASSICAL-Five-Band and CLASSICAL-Two-
Band
presets are optimized for classical music, gracefully handling recordings with very
wide dynamic range and sudden shifts in dynamics. The Five-Band version uses heavy
inter-band coupling to prevent large amounts of automatic re-equalization, which could
otherwise cause unnatural stridency and brightness in strings and horns, and which could
pump up very low frequency rumble in live recording venues.
The Five-Band preset defeats the AGC, using only the multiband compressor for gain
reduction. It also defeats phase rotation to ensure the most transparent Five-Band sound
available.
Even more transparent, “purist” classical processing is available from the
CLASSICAL-
Two-Band
preset, which is phase-linear and which preserves the spectral balance of the
original material as much as possible. However, if you need a bit more automatic re-
equalization than the
CLASSICAL-Two-Band preset provides, use the CLASSICAL-Five-
Band
preset.
CLASSICAL-5B+AGC uses the AGC set for 2:1 compression ratio. Because of the AGC,
it affects more of the total dynamic range of the recording than does the
CLASSICAL-5
BAND
preset. However, the AGC provides extremely smooth and unobtrusive compres-
sion because of the gentle ratio and window gating. This preset uses the Five-Band com-
pressor very lightly with a fast release time as a peak limiter. The AGC does almost all of
the compression.
There is also a corresponding two-band preset called
CLASSICAL-2B+AGC.
COUNTRY: The
COUNTRY-MEDIUM preset uses the ROCK-SMOOTH source preset. It
has a gentle bass lift and a mellow, easy-to-listen-to high end, along with enough pres-
