7 INPUT FILTER
These filters modify the signal that is processed by
the compressor. Use the buttons located at the right
to select the type of filter (HPF/LPF) and the on/off
setting. Use the knob located at the left to set the cut-
off frequency (common to LPF/HPF).
If LPF is on, the compressor will be applied to the
signal that has passed through the LPF, and will then
be mixed with the signal that has passed through the
HPF. If HPF is on, the compressor will be applied to
the signal that has passed through the HPF, and will
then be mixed with the signal that has passed
through the LPF.
In this case, the cutoff frequency of the LPF and HPF
will be linked.

4 Type
This indicates the type of the currently selected com-
pressor.
Hint
Normally, you will switch the compressor type by
recalling a different type of compressor in the
INPUT COMP LIBRARY window. It is not possible
to change the type in this screen.
5 COMP ON/OFF (compressor on/off)
This button switches the compressor on/off.
6 Graph
This graph shows the various parameter settings of
the compressor.

Hint
If you want this to function as a de-esser, use the
SELECT (key-in select) setting (F) described on the
following page to select SELF POST EQ.
8 THRESHOLD (threshold level)
This sets the nominal level at which the compressor
will begin to operate. When the key-in signal exceeds
this level, the input signal will start to be compressed.
When the key-in signal falls below this level, com-
pression will be defeated.
9 RATIO
This sets the ratio at which the input signal will be
compressed when the key-in signal exceeds the
threshold level.
0 ATTACK (attack time)
This sets the time from when the key-in signal
exceeds the threshold level until compression begins.
A RELEASE (release time)
This sets the time from when the key-in signal falls
below the threshold level until compression is
defeated.
B GAIN
This sets the gain of the output level.
