Parameter Setting Explanation
Level 0~127 Use this parameter to set
the compressor’s input level.
The higher the value, the
stronger the three frequency
bands are compressed.
The value you set here is
added to the “Level” settings
of the three bands. Do not
set this parameter to “0” if
the compressor is switched
on, because doing so means
that the keyboard parts, the
SMF song or Rhythm parts
are no longer audible.
Gain –12~0~
12dB
Use this parameter to cor-
rect the level at the com-
pressor’s outputs. If the
settings of the remaining
parameters lead to a signifi-
cantly lower level, select a
positive value. If your set-
tings lead to a significantly
higher level, select a nega-
tive value. “0” means that
the level is neither boosted
nor attenuated.
High/Mid/Low: Because “Attack”, “Release”, “Threshold”,
“Ratio” and “Level” are the same for each band, we will
only discuss them once. As you see, each of the three fre-
quency ranges has its own set of parameters that allow
you to specify their behavior.
Attack 0~100ms Use this parameter to spec-
ify how fast the compressor
of the band in question
should start processing the
signal once the level of that
band exceeds the “Thresh-
old” level. Choose a smaller
value if you prefer a com-
pression similar to that of
FM radio stations. Higher
values may yield a “snap-
pier” or “funkier” sound.
Release 50~
5000ms
This parameter allows you to
specify how fast the com-
pressor of the corresponding
band should stop working
when the signal level drops
below the “Threshold” value.
Threshold –36~0dB This parameter allows you to
set the level the frequency
band (“High”, “Mid” or
“Low”) must reach to trigger
its compressor. The lower
the value, the more notice-
able the compression will be.
Ratio 1:1.0~
1:INF
Use this parameter to spec-
ify how strongly the level
should be reduced when the
band’s level exceeds the
“Threshold” level. “1:2.0”, for
example, means that level
values above the “Threshold”
level are halved. “1:INF” is
useful if you set “Threshold”
to “0dB” or thereabout. This
produces a limiter effect,
which means that no signal
level will ever exceed the
“Threshold” value. This may
help you protect the speak-
ers of the PA system etc.
Level –24~
+24dB
This parameter allows you to
establish the desired mix
among the three compressor
bands. Choose a negative
value to decrease the level,
or a positive one to increase
it. Choose “0” for a band
whose level is OK as is.
Split High 2000~
12000Hz
These two parameters spec-
ify the frequency where two
bands are separated. The
compressor has three bands,
and so there are two cross-
over frequencies you can
set: “High” between the
“Mid” and “High” ranges;
and “Low” between the
“Mid” and “Low” ranges.
Split Low 80~800Hz
