Chapter 5 Changing the Overall Tone of the Sound and Acoustics (TSC)
■ Changing the Compressor
Parameters
This changes the parameters of the Sound Shape
compressor.
The Compressor compresses the overall output
signal when the input volume level exceeds a set
value.
The values that can be set for each of the
parameters are shown below.

Description
This parameter turns the
compressor effect on/off.
This sets the frequency (in the
lower range) at which the
source sound is split into
three separate ranges.
This sets the frequency (in the
upper range) at which the
source sound is split into
three separate ranges.
This sets the volume level at
which the lower-range com-
pressor goes into effect.
This sets the ratio of suppres-
sion of the lower-range out-
put when the input level
exceeds the Lo threshold lev-
el (COMP (Low) / Thres).
This sets the time it takes for
the lower-range compressor
to go into effect once the in-
put level exceeds the Lo
threshold level.
This sets the time it takes for
the lower-range compressor
effect to stop once the input
level falls below the Lo
threshold level.
This sets the volume level at
which the midrange com-
pressor goes into effect.
This sets the ratio of suppres-
sion of the midrange output
when the input level exceeds
the Middle threshold level
(COMP(Mid) / Thres).

COMP(Mid) 50 ms–

* With the compressor, the level is automatically adjusted
to the optimum setting according to the threshold
(Thres) and ratio (Ratio) settings. In addition, since
lengthening the attack (Attack) setting may result in
distortion, a buffer (margin) of -6 dB is provided. Adjust
the following parameter levels as needed.
COMP / -60 dB–
Low Lev +6 dB
COMP / -60 dB–
Mid Lev +6 dB
COMP / -60 dB–
High Lev +6 dB
COMP / -60 dB–
OutLevel +6 dB
Description
This sets the time it takes for
the midrange compressor to
go into effect once the input
level exceeds the Middle
threshold level.
This sets the time it takes for
the lower-range compressor
effect to stop once the input
level falls below the Middle
threshold level.
This sets the volume level at
which the upper-range com-
pressor goes into effect.
This sets the ratio of suppres-
sion of the upper-range out-
put when the input level
exceeds the Hi threshold lev-
el (COMP(Hi) / Thres).
This sets the time it takes for
the upper-range compressor
to go into effect once the in-
put level exceeds the Hi
threshold level.
This sets the time it takes for
the upper-range compressor
effect to stop once the input
level falls below the Hi
threshold level.
Sets the volume level of the
lower range after the signal
passes through the expander
and compressor.
Sets the volume level of the
midrange after the signal
passes through the expander
and compressor.
Sets the volume level of the
upper range after the signal
passes through the expander
and compressor.
Sets the overall volume level
after compressor.
