GAIN knob
6
This adjusts the GAIN in a range of -40.0 dB–+40.0 dB. This
adjusts the output level of the compressor.
If AUTO GAIN is on, the GAIN will have an effective range of -40.0
dB–+6.0 dB. If the GAIN value is outside the effective range, the
value will be shown in red.
When the COMPRESSOR popup is displayed, the compressor
can be adjusted using the EQUALIZER area controls for the
CHANNEL EDIT section.
Press [HI MID ] / [HI ] to select PARAM1 or PARAM2, and
use Q/FREQ/GAIN knobs to control the corresponding
parameters.

7 KEY-IN SELECT popup button
This accesses the KEY-IN SELECT popup window where you
can select the key-in signal. For stereo-linked channels, there
are two buttons (L and R). The channel currently selected as
the key-in signal is shown on the button.

FREQ knob

This adjusts the frequency in a range of 20 Hz–20.0 kHz.
The function buttons have the following operations:
[F1 (OVERVIEW) Accesses the COMPRESSOR OVERVIEW popup
(p. 77).
[F2 (COMP ON)] Turns the compressor on/off.
[F3 (AUTO GAIN)] Turn AUTO GAIN on/off.
[F4 (LIBRARY) Accesses the COMP LIBRARY popup window
(p. 77).
[F5 (PEAK CLEAR)] Clears the level meter's peak hold or over
indication.
[F7 (KEY-IN SOLO)] If you turn this on, you can hear the output
signal of the key-in filter (p. 76).
[F8 (CLOSE)] Closes the popup.
If you turn AUTO GAIN on, the output response of the
compressor will be boosted as high as possible while
maintaining 6 dB of headroom.
The compressor will narrow the dynamic range, since it
reduces the output of incoming signals that exceed the
threshold level. If AUTO GAIN is on, the upper limit of the
output level when ATTACK time is 0 ms will be boosted while
maintaining 6 dB of headroom from clip level (0 dB), thus
maximizing the dynamic range.
The 6 dB of headroom is maintained in order to prevent the
compressor's output from clipping during the attack portion
of the input signal when the ATTACK time is set to a longer
value.
