more automatic re-equalization than the
CLASSICAL 2-BAND
preset provides, use
the
CLASSICAL 5-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.
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
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
or
ROCK-OPEN
useful if they want a brighter, more up-front sound.
While there are no specifically named Country MX presets, we suggest that modern
country stations experiment with
ROCK-MEDIUM MX, ROCK-SMOOTH MX, ROCK-
SOFT MX,
and
GREGG MX
presets. Classic country stations should try the
GOLD
OPEN MX
preset.
CRISP, CRISP MX:
CRISP
is an 8500-style preset that provides a bright upper mid-
range sound by emphasizing frequencies around 6 kHz. It is a loud preset that is ap-
propriate for mass-appeal music formats.
There are two MX CRISP presets:
•
CRISP+MIDBASS MX
has the same basic bass texture as the
IMPACT MX
preset
and is targeted more toward smaller table radios with substantial bass response
to 100 Hz but little below that.
•
CRISP+LOWBASS MX
has the same basic bass texture as the GREGG MX preset.
It puts more energy in the frequency range below 120 Hz and is targeted more
towards premium auto radios and other radios with substantial bass response be-
low 100 Hz.
Measured in third-octaves, the two presets typically produce less than 3 dB of differ-
ence with program material, so either preset will work OK (although not ideally)
with all radios.
DANCE ENERGY: This 8500 preset is designed to preserve the punch and slam in
dance music percussion (such as the beater click in kick drums). It uses
H
ARD
bass
clipping, is loud, and has a bright high frequency texture. It was designed for 50 µs
pre-emphasis and many user will find it to be too distorted when used at 75 µs. As
L
ESS
-M
ORE
is turned down, this preset get quieter, yet punchier.
EDGE MX
is also appropriate for dance-oriented stations and will outperform
DANCE ENERGY
by producing more transient impact, more HF energy, and lower
