7.
If necessary, rotate the [CURSOR÷VALUE]
dial to select “On”, then press the dial.
The compressor is now active and will affect SMF
song playback.
8.
Rotate the [CURSOR÷VALUE] dial to select
the “Preset” parameter, then press the dial.
9.
Rotate the [CURSOR÷VALUE] dial to select
one of the available presets, then press the
dial.
The available presets are:
10.
If none of the preset memories contains the
settings you need, use the [CURSOR÷VALUE]
dial to select and set the following parame-
ters:
Parameter Setting range 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” set-
tings of the three bands.
If you set this parameter
to “0”, the compressor
has no effect on the out-
put signal.
Gain –12~0~12dB Use this parameter to
correct the level at the
compressor’s outputs. If
the settings of the
remaining parameters
lead to a significantly
lower level, select a posi-
tive value. If your set-
tings lead to a
significantly higher level,
select a negative value.
“0” means that the level
is neither boosted nor
attenuated.
High/Mid/Low: Because the remaining parameters are
the same for each band, we will only discuss them once.
As you see, each of the three frequency ranges has its
own set of parameters that allow you to specify their
behavior.

2. Soft Comp
3. Low Boost
4. Mid Boost
5. High Boost

Attack 0~100ms Use this parameter to
specify how fast the
compressor of the band
in question should start
processing the signal
once the level of that
band exceeds the
“Threshold” level. Choose
a smaller value if you
prefer a compression
similar to that of FM
radio stations. Higher
values may yield a
“snappier” or “funkier”
sound.
Release 50~5000ms This parameter allows
you to specify how fast
the compressor of the
corresponding band
should stop working
when the signal level
drops below the “Thresh-
old” value.
Threshold –36~0dB This parameter allows
you to set the level the
frequency band (“High”,
“Mid” or “Low”) must
reach to trigger its com-
pressor. The lower the
value, the more notice-
able the compression
will be.
Ratio 1:1.0~1:INF Use this parameter to
specify how strongly the
level should be reduced
when the band’s level
exceeds the “Threshold”
level. “1:2.0”, for exam-
ple, means that level val-
ues 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 speakers 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.
