different pieces of source material than does the Two-Band structure,

almost always preferable to the Two-Band structure for any popular music for-

The Medium Slow settings (
M
ED and
M
ED
2
) are appropriate for more adult-
oriented formats that need a glossy show-business sound, yet whose ratings de-
pend on maintaining a longer time spent listening than do conventional Con-
temporary Hit Radio (CHR) formats. With the single-ended noise reduction acti-
vated, it is also appropriate for Talk and News formats. This is the sound texture
for the station that values a clean, easy-to-listen-to sound with a tasteful amount
of punch, presence, and brightness added when appropriate. It is an unprocessed
sound that sounds just right on music and voice when listened to on small table
radios, car radios, portables, or home hi-fi systems.

The Medium Fast settings (
MF
AST
and
MF
AST
2
) are ideal for a highly competi-
tive Contemporary Hit Radio (CHR) format whose ratings depend on attracting a
large number of listeners (high “cume”) but which does not assume that a lis-
tener will listen to the station for hours at a time. This is the major market com-
petitive sound, emphasizing loudness as well as clean audio. The sound from cut
to cut and announcer to announcer is remarkably consistent as the texture of
music is noticeably altered to a standard. Bass has an ever-present punch, there is
always a sense of presence, and highs are in perfect balance to the mids, no mat-
ter what was on the original recording.

The Fast setting is used only for the

formats. Processing for this sound keeps the levels of announcers and guests con-
sistent, pulls low-grade telephone calls out of the mud, and keeps a proper bal-
ance between voice and commercials. Voice is the most difficult audio to process,
but these settings result in a favorable trade-off between consistency, presence,
and distortion.
The Factory Presets for this sound are quite different from the other three re-
lease time settings. The amount of gain reduction in the multiband compressor is
substantially lower (so that it operates more like a limiter than like a compressor)
and the release time of the gain-riding AGC is speeded up (so that it provides
compression and some increase of density). We made these trade-offs to prevent
excessive build-up of density.
It is possible to experiment with this sound for music-oriented programming as
well. However, even with these settings, your sound is getting farther away from
the balance and texture of the input. We think that this is as far as processing
can go without causing unacceptable listener fatigue. However, this sound may
be useful for stations that are ordinarily heard very softly in the background be-
cause it improves intelligibility under these quiet listening conditions. Stations
that are usually played louder will probably prefer one of the slower release
times, where the multiband compressor takes more gain reduction and where
the AGC is operated slowly for gentle gain riding only. These slower sounds are
less consistent than those produced by the
F
AST setting. Using
