OPERATION
You can minimize this effect by carefully setting the MB G
control to "freeze" the gain when the input gets quiet and/or by activat-
ing the single-ended noise reduction.
When the multiband compressor's release time is set to its faster settings, the setting
of the MB D control becomes more critical to sound quality because density in-
RIVE
creases as the control is turned up. Listen carefully as you adjust it. With these fast
release times, there is a point beyond which increasing multiband compressor drive
will no longer yield more loudness and will simply degrade the punch and definition
of the sound.
We recommend no more than 10 dB gain reduction as shown on the meters for
band 3. More than 10 dB, particularly with the F
"wall of sound" effect that many find fatiguing.
To avoid excessive density with the F
ommend using no more than 5 dB gain reduction in band 3 and compen-
sating for any lost loudness by speeding up the MB R
MB Release; Speech MB Release control can be switched to any one of seven set-
tings:
•
The Slow settings produce a very punchy, clean, open sound that is ideal for
Adult Contemporary, Soft Rock, Soft Urban, New Age, and other adult-oriented
formats whose success depends on attracting and holding audiences for very
long periods of time. The S
sound with a nice sense of dynamic range. With these settings, the Five-Band
structure provides gentle automatic equalization to keep the frequency balance
consistent from record to record (especially those recorded in different eras). For
background music formats, these settings ensure that your sound doesn't lose its
highs and lows. Because it creates a more consistent frequency balance between
different pieces of source material than does the Two-Band structure, S
almost always preferable to the Two-Band structure for any popular music for-
mat.
•
The Medium Slow settings (M
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
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
release time, will often create a
