OPTIMOD-AM DIGITAL

OPERATION

3-25

Presets with “LBR” in their names are tuned to minimize artifacts with low bitrate
codecs by using the Band 5 compressor to control excessive high frequency energy.

CLASSICAL 5B

: As its name implies, the

CLASSICAL-5B

preset is optimized for clas-

sical music, gracefully handling recordings with very wide dynamic range and sud-
den shifts in dynamics. It 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.

COUNTRY:

The

COUNTRY-MEDIUM

preset uses the

ROCK-SMOOTH

source preset.

has a gentle bass lift and a mellow, easy-to-listen-to high end, along with enough
presence energy to help vocals to stand out. The

COUNTRY-LIGHT

preset uses the

ROCK-LIGHT

source preset. Modern country stations might also find

ROCK-MEDIUM

ROCK-OPEN

useful if they want a brighter, more up-front sound.

CRISP:

CRISP

provides a bright upper midrange sound by emphasizing frequencies

around 6 kHz. It is a loud preset that is appropriate for mass-appeal music formats. It
has the same bass texture as the

IMPACT

presets.

DANCE ENERGY:

This preset is designed to preserve the punch and slam in dance

music percussion (such as the beater click in kick drums). It is loud and has a bright
high frequency texture. As

ESS

-M

ORE

is turned down, this preset get quieter, yet

punchier.

EDGE:

This preset is designed for hit music stations that prefer extremely punchy

bass to fastidious distortion control. It is loud and has a bright high frequency tex-
ture.

FOLK / TRADITIONAL:

FOLK

TRADITIONAL

is an alias for the

ROCK-SOFT

preset.

It assumes that the recordings are of relatively recent vintage and require relatively
subtle processing.

If the recordings you play are inconsistent in texture and equalization, you may pre-
fer the

ROCK-SMOOTH

or ROCK-LIGHT presets.

GOLD:

GOLD

is loud and “hi-fi”-sounding while still respecting the limitations and

basic flavor of the recordings from the era of the 1950s through 1970s.

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, dis-

torted, or have other technical problems that make them unpleasant
sounding when the processor over-equalizes them in an attempt to emu-
late the high frequency balance of recently recorded material.

GREGG:

GREGG

OPEN

, and

GREGG

LBR

all use a 200 Hz band1/band2

crossover frequency to achieve a bass sound similar to the classic five-band Gregg
Labs FM processors designed by Orban’s Vice President of New Product Develop-
ment, Greg Ogonowski. Dynamically, these presets produce a slight increase in bass
energy below 100 Hz and a decrease of bass energy centered at 160 Hz. This bass
sound works particularly well with radios having good bass response, such as many
auto radios today.
