19. COMPRESSOR ATTACK CONTROL
This determines when the compression sets in
once the signal has exceeded threshold.
The setting range is from 0.3 to 300ms.
20. COMPRESSOR AUTOKNEE SWITCH WITH LED
This switch toggles between "hard knee"
and AUTOKNEE characteristic: Input signals
exceeding threshold by up to 10 dB will be
processed with a "soft knee" characteristic.
Above 10 dB the control characteristic changes
from "soft knee" to a more conventional
"hard knee" compression. The AUTOKNEE
characteristic allows for a subtle and musical
compression of the program material, with
inaudible compression.
21. COMPRESSOR AUTOTIME SWITCH WITH LED
This switch disables the ATTACK and RELEASE
controls and derives these time values
automatically from the program material. It
thus allows for a heavy and, at the same time,
musical compression of signals with varying
levels or of complex program material.
22. COMPRESSOR RELEASE CONTROL
This sets the time when the original 1:1 gain is
reached, after the signal has dropped below
threshold again. The setting range is from 0.05
to 5 s.
23. COMPRESSOR ENABLE SWITCH WITH LED
This activates the corresponding compressor
channel. It provides a so-called "hard bypass",
i.e. if it is OUT or the unit is not connected to
the mains, the input jack will be linked directly
to the output jack. Usually, this switch is used for
direct A/B comparison between unprocessed
and compressed/limited signals.
24. DYHANCE SWITCH WITH LED
Activates the dynamic enhancer circuit which
allows you to dynamically enhance the treble
range. Since the bass portions of a music signal
often have the highest energy yield, they usually
are the ones that trigger the compression
process, thus also reducing the gain of middle
to high frequencies. The enhancer controls
the compression process and gradually adds
more highs, the stronger the treble range is
compressed, to make up for the subjective loss
of high-frequency content.
DE-ESSER
25. DE-ESSER LEVEL CONTROL
The controllable de-esser helps to eliminate
hiss noise contained in the audio signal. This
control determines the amount of frequency
suppression.
26. MALE SWITCH WITH LED
This switch adapts the de-esser to the male
(switch pressed) or female registers (not
pressed).
27. DE-ESSER LEVEL DISPLAY
This LED chain shows the attenuation within a
range from +3dB to +12dB.
28. DE-ESSER IN/OUT SWITCH WITH LED
Switches the de-esser on and off. Note: the
de-esser is placed in the side-chain path of
the compressor, so it will operate only if the
compressor is active.
