Switches
Control Elements
Please note also the information on various controls under „Understanding
and enjoying the Kultube“ starting page 12.
RED/VU
This switch changes the VU meter over to Gain Reduction mode. The indicator
needle then jumps to the 0 dB value and moves to the left with increasing
compression. The scaled values now refer to gain reduction.
If the RED/VU switch is not pressed, the VU meter indicates the output
level.
If neither the RED/VU nor the ACTIVE switch is pressed, the VU meter indi-
cates the input level. In Slave mode gain reduction is controlled by the master
device.
DIGITAL INPUT
With the optionally available digital converter module you can use the DIGITAL
INPUT switch to select the converted digital signals as an input source for
the Kultube. The converter module thus adds digital in- and outputs to the
Kultube, allowing it to be easily integrated into a digital production chain.
SOFTKNEE
SOFTKNEE alters the slope of the compressor. Normally the unit operates in
hardknee mode, but pressing the SOFTKNEE switch places the unit in soft-
knee mode.
Softknee provides generally less conspicuous and softer compression
results; the greatest possible loudness however can only be achieved in hard-
knee mode. The slope of the curves is shown on page 13.
DE-COMP:
This switch activates Decompression mode. This mode causes the compressor
to work in reverse: All signals above the preset threshold become louder, and
the Ratio controller determines the intensity of the volume increase. Please
note that the Make-Up controller now works exactly in reverse: the signal
becomes softer when the controller is turned to the right and louder when
turned to the left.
