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!
