OPERATION

ORBAN MODEL 8300

fine-tune the frequency balance of the programming, feel free to use Basic Modify
and make small changes to the Bass, Mid EQ, and HF EQ controls. Unlike some ear-
lier Orban’s processors, the 8300 lets you make changes in EQ (and stereo enhance-
ment) without losing the ability to use

settings.

Of course,

is still available for the unedited preset if you want

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 100 ms 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 off-air cueing of fin-
icky talent, for example).

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

ORE

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 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.
