Moscow's Bolshoi Theatre
Russia - Moscow's Bolshoi Theatre has undergone a major refurbishment. As well as renovation and construction work, the theatre management decided to invest heavily in state-of-the-art communications equipment.

The nerve centre is the largest RTS professional intercom system for stage management worldwide with six interconnected individual stage-manager systems, and here they were prepared to accept no compromises. For this reason, the Hamburg-based specialist Amptown System Company was charged with the installation.

"The new intercom system had, above all, to guarantee one thing," explains Stefan Thomsen, Amptown System Company's specialist in communications and stage-management systems, "that all those involved in a production would be able to exchange information with each other at any time without any problem."

Furthermore, the system - however complex in its implementation - had to be simplicity itself to use; and not only to use, but also to configure. Two further teams of specialists - the Russian company TDM and ProVideo of Berlin - were called in to participate with Amptown's and the theatre's own technicians in the final decision. The result? The RTS intercom matrix combined with an RTS two-wire party-line intercom system that now forms the core of all communications within the Bolshoi Theatre.

The RTS intercom system consists of two Advanced Digital Audio Matrix (ADAM) frames with a total of 448 ports, the frames being linked by four redundant DBX cards. 200 keypanels from the KP-32, KP-12 and MKP-4 series as well as 120 party-line belt-packs and headsets provide for reliable communication between the stage managers and theatre staff behind, beneath and above the stage. Numerous DSI-2008 two-wire/four-wire interfaces are used to link the four-wire ADAM and two-wire party-line systems to one another. The installation is rounded off by 20 TIF-4000 multi-line telephone interfaces that connect the intercom system to the theatre's telephone switchboard to integrate standard telephone lines into the overall matrix.

"The new stage-management system can be operated from any of six stage-manager's desks in different parts of the theatre," adds Thomsen. "The SNMP protocol provides supervision of the system components. Naturally the RTS intercom system is also integrated via SNMP into the supervision concept. Should the situation arise, this system is capable of analysing any error reports and passing the information along in the form of voice-mail, SMS or e-mail messages."
