Salzbrenner Media refurbishes Tbilisi opera house
WORLD: German systems integrator, Salzbrenner Media, was called in for the comprehensive upgrade of the Zakaria Paliashvili Tbilisi State Academic Theatre of Opera and Ballet. The company planned, documented, supervised, and installed the systems. It then followed this up with commissioning and training, including a week of intensive training modules for the state-of-the-art technology.
The refurbishment of the building was a six year project with the technical side running from March 2013 until January 2016. The opera house was completely gutted and equipped with state-of-the-art technology to support future productions in a project financed by Cartu, a fund owned by Georgian tycoon and former Prime Minster Bidzina Ivanishvili, the man who formed the Georgian Dream coalition.
Salzbrenner Media took responsibility for the planning, outfitting and installation of the audio, video and stage management equipment. The Tbilisi opera house now has an extensive stage management system from the Salzbrenner PerformanCeTRL product line. This comprises components from the Delec Oratis intercom series including a Talk 16 subscriber unit and provides all the audio functions and logic programming. Salzbrenner MediaControl handles the control and also deals with the signals for the many cue lights labelled in Georgian characters. Wireless radio and partyline intercom is based on a combination of Riedel, Motorola and Telex components, all controlled by the Delec and MediaControl systems. A video infrastructure with two Panasonic cameras, interfaced with SDI, routing processing and monitor screens complements the stage management system.
Audio mixing in the main auditorium is taken care of by a 42 fader StageTec Auratus mixing console in the sound control room connected via a Nexus audio network with four base devices and a total of 77 I/O cards. A 5.1 audio monitoring solution has been installed alongside TFT displays from LG, a custom-made control desk and 30U rack cabinet by Salzbrenner Media’s mechanical engineering department and multimedia equipment including recording and playout units.
Apart from the main stage a number of rehearsal stages and rooms have been equipped with mobile and self-powered KS Audio full range speaker systems, three TASCAM 16-channel analogue audio mixers and dynamic microphones from beyerdynamic.
Reinforcement in the opera house needed to be as unobtrusive as possible. For this reason subwoofers are located in the orchestra pit and 16 KS line array loudspeakers along with two Seeburg column loudspeakers.
Alongside the audio and video cabling, an extensive data network for general purpose signal distribution as well as control of all relevant system components, such as the PA and wireless mics, was also installed. For external productions additional video distribution has been added, based on a Triax cable network.
