WMS 4000 46-CHANNEL SETUP

EXAMPLE: 46-CHANNEL SYSTEM FOR AN OPERA HOUSE

As regards planning, technology, and monito- ring, wireless installations in opera houses pose a particular challenge. Unfailingly high sound quality and "invisible" installation of the com- ponents are basic requirements for offering the audience a unique auditory experience.

Structural issues pose much greater difficul- ties: as a rule, opera houses are historic buil- dings subject to strict conditions with regard to constructional alterations. And the numerous backstage rooms, such as dressing rooms, maintenance passages etc. are an environment

that is rather hositle to RF propagation. Above all, however, there is one feature typical of many opera houses: the so-called “iron cur- tain” that separates the stage and auditorium. A massive metal wall, it completely blocks radio signals when lowered.

In our case, we needed a 46-channel system centrally controlled from the control room. The stage was approx. 70 m (230 ft) away from the control room and had to be covered with the minimum possible number of antennas. Besides, the transmitters in the dressing room

had to be operational, so that the correct func- tioning and level settings could be tested prior to showtime.

The system uses two passive directional anten- nas placed close to the control room to cover the stage. Antenna combiners connect two omnidirectional booster antennas in the dres- sing room, which receive the radio signals from behind the stage. This ensures perfect trans- mission and monitoring of all transmitters even during intermissions, when the iron curtain is lowered.

High-tech for pure enjoyment

Every opera or theater audience has a right to enjoy excep- tional artistic performances and excellent sound. Therefore, microphones and wireless components must not only work perfectly but be more or less invisible in order not to disrupt the visual appeal of the stage set and performers. The com- pact WMS 4000 and AKG MicroMics provide the ideal com- bination for this type of application.
