Sidechain inputs
This jack is used as a sidechain input for connecting an external audio signal to control the Kultube (e. g. an equalizer for frequency dependent processing). It is configured as a stereo RCA jack, with the left channel on the tip and the right channel on the ring.
Ideally you should use a normal insert cable that combines a stereo RCA plug (connected to the Kultube) and two mono RCA plugs (connected to the control device). When using an equalizer you can connect its inputs to the unused jack inputs on the Kultube. In this way both the equalizer and the Kultube get the same signal, since the XLR and RCA jacks are wired in parallel.
To use the sidechain input, activate the KEY ON switch on the front panel. To monitor the signal, activate the KEY LISTEN switch. For other notes on using the sidechain function, see the section on page 20.
Multi Channel Link
The MULTI CHANNEL LINK jacks can be used to connect multiple Kultube units for
CAUTION – NOTE WARNING: Always define only one master device! Never connect more than one device through the MASTER jack – otherwise compo- nents may be destroyed!
After you have made the cable connections, the SLAVE switch on the front panel of each slave unit must be activated. From now on all functions of all slave units are controlled by the master.

Hum? Ground Lift!
Hum can be eliminated with the GND/LIFT switch on the rear of the unit (isolates the internal ground from chassis ground). Hum can occur for example when the Kultube is connected to devices having a different ground potential.
Hum problems can also be avoided however by consistently installing balanced wirings. For this reason the GND lift function is by default not activated.
