Since the first CANTUS was installed in 1995, the Stage Tec console has been shipped to almost every continent in the world, being welcomed enthusiastically everywhere. The most distant installation of a Stage Tec product is 6,000 miles from its origin: in Japan.

Wakayama Municipal

Of Foreign Countries and People *

* From »Scenes of Childhood« by Robert Schumann (German composer, 1810 – 1856)

CANTUS at Wakayama, Japan

The 'Scenes' that romantic composer Robert Schumann once wrote as a series of etudes for young pianists have since become a part of the standard classical piano repertoire. Classical music from Europe is appreciated all over the world – from Paris to New York and even Sydney. In particular, this is true for Japan as the major musical stronghold outside Europe. There in Wakayama, a town some 20 miles from Osaka, you will find a CANTUS desk with a slave console and six NEXUS base devices. A system that has traveled as far as the music that flows through it.

Other Countries, Same Technology

Like similar halls in other countries, the new concert hall (officially known as the Municipal Hall) at Japanese industrial town Wakayama is used for all kinds of events: from traditional Japanese music to classical music, from the latest pop music all the way to conventions When the venue was refurbished, the city council decided it was time to install a sound-reinforcement system capable of coping with live events and with recording of such events in high quality – this is the difference to other concert halls! For that reason, it was decided to look into high-quality audio equipment that was both flexible and suited a wide range of applications.

Equality for All

CANTUS at Wakayama, Japan

For most events, just the main console in the control room is needed. Somewhat reminiscent of a crow's nest, this room is located high above the seats just under the roof. The control-room window provides just enough room for the main CANTUS console and its 36 channel modules (though admittedly only after shortening the console's legs by four inches – this was the only option which ensured the sound engineer retained visual contact with what is going on on stage).

The control room is also used for live recording and productions that require proper acoustic isolation from the hall. In contrast, sound-reinforcement applications are mixed directly in the auditorium using a second portable CANTUS console. This slave console includes 32 fader modules and a separate Central Control Unit – not something you would normally expect from a CANTUS slave console used in split mode. This is, however, a must to provide access to all signal sources for public-address applications and to configure completely separate mixes. The two consoles provide more than 100 channels using only one single DSP rack. Therefore, the DSP channels can be split and thus accessed individually from either console.

Special Requirements

It is not only the consoles that can be used in parallel. Auxiliary signal sources and recording devices can also be operated individually from either console. To this end, Stage Tec designed a special panel for parallel remote control of six tape machines.

Another personal touch is presented by the multicolored faders and pots on both consoles – the response to the client's requirement for a transparent user interface. Apart from this, the specs of the Japanese CANTUS are similar to those installations found elsewhere; citizenship and culture do not affect fundamental concepts such as a straightforward storage function for entire projects, superb audio quality and – especially important for live applications – a high degree of reliability of the Stage Tec components.

On Either Side…

Anyone who has been to Japan will tell you that the people and culture are fairly unlike anything they have previously encountered. Yet, once you start digging, you discover quite a few similarities that apply everywhere: the quest for quality, reliability, and flexibility. This may be the explanation for the success of CANTUS in every corner of the world.
 

 

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!
