Again, while Kultube‘s housing is EMV-proof and protects against
HF-interference, placement of the unit is very important since it amplifies
microphone signals as well as other unwanted signals. Before connecting the
Kultube or any other equipment turn off all power. Adjust the voltage setting
on the back so that it corresponds with the power conditions.
The following graph shows the correct wiring for connecting unbalanced
signals to the balanced XLR connectors:
Alternatively unbalanced signals can be connected with mono Jack connec-
tors to the balanced Jack sockets.
Analog XLR and RCA jacks
Symmetrical XLR and RCA jacks are used for analog in- and outputs. An analog
mixing console is generally connected here (Insert Send/Return). Since the
RCA and XLR jacks are wired in parallel, unbalanced operation of the RCA
jack will have the same effect on the XLR jack and vice-versa. The Kultube is
configured for a nominal level of +4dBu and can handle an input level of max.
25 dBu, with max. +23 dBu available on the output. It is recommended to drive
the Kultube with a signal level of between 0 dBu and 12 dBu – this being the
optimum drive range for signal processing in which also the signal-to-noise
ratio is the best.
