lier Orban's processors, the 5500 lets you make changes in EQ (and stereo enhance-
ment) without losing the ability to use L

to go back to it. There is no way you can erase or otherwise damage the
Factory Presets. So, feel free to experiment.
If a preset has 2-Band in its name, it will activate the Two-Band structure.
Switching between the Two-Band and Five-Structures occurs via a smooth cross-fade.
If the preset has "UL" in its name, it will load the Ultra-Low Latency Five-Band struc-
ture. Note that if you switch between an "UL" preset and any other preset, the au-
dio will mute for about two seconds to allow time for new DSP code to load into the
DSP chips and to initialize. "UL" presets are not as competitive as other presets and
should only be used if you absolutely need the low delay (for example, when driving
talent headphones off-air during remote broadcasts).
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
limiting in the highest quality applications such as serious classical music intended
for an attentive audience. Its L
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 re-
cording 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. This 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 un-
obtrusive compression because of the gentle ratio and window gating. This preset
uses the Five-Band compressor very lightly with a fast release time as a peak limiter.
The AGC does almost all of the compression.
