Progressive Time Control: ATTACK
This function allows to switch in an adjustable automatization of the time
constants which is set up with the ATTACK control.
Put simply you can now influence the compression intensity for rapid signal
increases, or when the function is turned off determine the time until a certain
compression level is reached.
Progressive Time Control: RELEASE
The release times can also be switched to automatic based on the Release
control: the latter then determines an average value to return the release to.
Use of the Progressive Time Control is especially recommended with complex
summed signals.
KEY ON
KEY ON allows you to use an external signal as the control source for the
compressor.
This signal is brought in to the SIDECHAIN INPUT jack on the rear of the unit.
Now the control activity of the compressor is determined only by the external
signal.
KEY LISTEN
Use the KEY LISTEN switch to monitor the external side-chain signal. This
makes it easy for example to monitor and adjust a connected equalizer.
Whereas the VU meter normally indicates the in- and output level, enabling
KEY LISTEN causes the meter to indicate the side-chain signal. This provides a
quick way to check also whether a signal is present.
SLAVE
This allows you to switch the Kultube to Slave mode so that it can be controlled
from the Master device. All the function except for TUBE HARMONICS are now
controlled by the Master. Both the Master and all the Slave units now get the
same control signal. Also the Slave unit signals are evaluated for analysis.
ACTIVE
The ACTIVE switch turns on the Kultube. If the device is not turned on, the
input signal is fed directly to the output jacks via a relay hard bypass. The
ACTIVE switch thus allows for a quick A/B comparison. When the Kultube
is turned on the LED on the ACTIVE switch flashes to indicate the warm-up
process for the tubes. The unit is ready when the LED no longer flashes.
