ended noise reduction.
When the release time of the multiband compressor is set to its faster settings, the
setting of the
M
ULTIBAND
D
RIVE
control becomes much more critical to sound quality
because density increases 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
AST
release time, will often create a
“wall of sound” effect that many find fatiguing.
To avoid excessive density with the
F
AST
multiband release time, we recommend us-
ing no more than 5 dB gain reduction in band 3, and compensating for any lost
loudness by speeding up the
M
ULTIBAND
R
ELEASE
instead. This is what we did in the
factory

MB REL (“Multiband Release”) control can be switched to any one of seven settings:
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. The
SLOW
and
SLOW2
settings produce
an unprocessed sound with a nice sense of dynamic range. With these
settings, the Five-Band structure provides gentle automatic equalization
