OPERATION ORBAN Model 8400
In terms of loudness, midrange texture, and HF texture, these presets are similar to the
LOUD-HOT+BASS presets.
The GREGG presets were introduced with version 3.0 software.
MINIMUM DELAY: This is a general-purpose preset using low latency mode to
achieve a delay of 15 ms (even though it does not have an “LL” in its name). We have
retained this preset for compatibility earlier versions. We have also attempted to retain
some of its open sound—a sort of “8200 on steroids”—while improving its high fre-
quency distortion control and peak control properties by comparison to the
MINIMUM
DELAY
preset in version 1.0 software.
OLDIES: There are four
OLDIES presets.
GOLD is optimized for music recorded from the 1950s through the 1970s by exploiting
8400 DSP features that were unavailable when the original series of “Oldies” presets was
created. (
GOLD was first introduced with version 2.1 software.)
Although the original “Oldies” presets were tuned for a nostalgic, “AM-radio” type of
quality, we expect that most oldies or “solid gold” formatted stations will prefer the new
Gold preset because it is substantially louder and more “hi-fi”-sounding, while still re-
specting the limitations and basic flavor of the recordings from this era.
For example, we do not attempt to exaggerate high frequency energy in the
Gold preset. The highs in recordings of this era are often noisy, distorted, or
have other technical problems that make them unpleasant-sounding when
they are over-equalized in an attempt to emulate the high frequency balance
of recently recorded material.
OLDIES-MODERN
is designed for records from approximately 1965 to the present. It is a
bit more conservative than the
ROCK presets and is designed to effectively re-equalize
recordings from different eras.
OLDIES-CLASSIC is specially tuned to complement “Top-40” records from the early
1950s through the mid-‘60s. Recordings from this era often had extremely present vocals
with audible soft clipping from the vacuum tube consoles and mic preamps used at the
time. Soft clipping (either on the master tape or when the songs were cut to disc) was of-
ten used to make the records cut through when played on jukeboxes and AM radio
(which used very simple audio processing back then).
OLDIES-CLASSIC preserves the
unique sound quality of these classic recordings without significantly changing the tex-
ture.
OLDIES-PROCESSED is tuned for the same records as OLDIES-CLASSIC, but is de-
signed for a louder sound that will significantly change the texture of the source material.
It is purposely tuned for a “retro” spectral balance with a hint of “AM-radio” quality—
highs are smooth, mellow, and rolled-off, while the midrange is prominent.
NEWS-TALK: This preset is quite different from the others above. It is based on the
fast
multiband release time setting, so it can quickly perform automatic equalization of sub-
standard program material, including telephone. It is very useful for creating a uniform,
