Master and Servant – How
to Use Slave Consoles
When going CANTUS, you do not just replace an analog console with
a digital one; you also have the opportunity to reorganize long-standing
procedures and the entire workflow. Combining a main console with
a slave desk opens up a completely new range of flexible options.
What's more: CANTUS supports both parallel and integrated operation.
The Basics
The possibility of using multiple combined mixing consoles is not
an achievement of digital technology. That technique was already
in existence in analog days, especially for sound-reinforcement applications
at major events. However, in those days, one had to cascade the consoles,
i.e. passing the master bus of one console to the next one, because
each desk continued to behave as a separate unit.
Unlike, the CANTUS allows for integrated use of a slave console
connected to the main desk. This is possible because a CANTUS console
operated by the sound engineer is actually a sophisticated remote
control while all audio processing is executed in a separate DSP
rack. This is the reason why a DSP unit can be accessed by both the
main and a slave console. Not only does this open up a variety of
options for the distribution of tasks but it is also easy on the
budget.
Parallel or Split Operation?
How would you like the two consoles to join forces? CANTUS provides
two options for combining a main console with a slave desk: split
and parallel operation. Most CANTUS setups are designed for parallel
operation. In Wakayama, however, split mode proved more practical
for the jobs at hand. In split mode, both consoles remain autonomous
though they share the same DSP unit. In Wakayama, this duo is necessary
for concerts requiring sound reinforcement. The CANTUS slave console
in the hall functions as FOH sound-reinforcement console while the
main surface in the control room serves as recording desk.
On the other hand, parallel operation means that the two consoles
do not work independently but together: while the engineer in the
hall takes care of the FOH mix, his colleague at the control room
starts and stops the required auxiliary signal sources. All settings
are transmitted in realtime via an optical cable and can be monitored
from the other console. This means that if the sound engineer raises
a fader on one console, the corresponding fader on the other console
will move to the respective position, too. For the first time ever,
the assistant can actually assist the sound engineer without getting
in the way while the sound engineer can be confident that the assistant
only does what he is supposed to do.
The only drawback, so to speak, is that you have to make up your
mind about how the consoles will be used before purchasing them because
the desired workflow requires two rather different technical configurations.
We Are Family
The basic concept, though, is the same for both modes: there is
only a single main console directly connected to the DSP unit. Up
to three slave consoles can be connected to the main desk and be
used for any combination of parallel or split operation. The main
console takes care of transmitting the required settings to the DSP
units.
Wiring up the main and slave consoles is easy: as for all Stage
Tec components, the required connections are established via a single
optical cable.
The main console contains the software that controls how the various
desks work together, thus ensuring that no slave console has access
to unauthorized DSP resources. The resulting flexibility is unique
on the market place!
