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.
7.
THRESH knob
This adjusts the threshold level in a range of -40.0 dB–0.0 dB.
8.
RATIO knob
This adjusts the RATIO in a range of 1.00:1–INF:1(14 steps).
9.
KNEE knob
This adjusts the KNEE in a range of HARD to SOFT1–SOFT9
(ten steps). The way in which the compressor applies to the
region near the threshold level can be adjusted between steep
(HARD) and gradual (SOFT9).
10.
ATTACK knob
This adjusts the ATTACK time in a range of 0.0 ms–800.0 ms.
This is the time from when the input signal exceeds the
threshold level until the compressor reaches its maximum
effect.
11.
RELEASE knob
This adjusts the RELEASE time in a range of 0 ms–8000 ms. This
is the time from when the signal falls below the threshold level
until the compressor is no longer applied.
12.
GAIN knob
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.
In the COMPRESSOR popup window, the function buttons perform
the following operations.
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.
1.
In the fader module section, press a [SEL] button to select
the desired channel.
2.
In the COMP area of the CHANNEL EDIT section, press
[DISP].

hold or over indication.
[F8 (CLOSE)]

Accessing the COMPRESSOR popup
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.
