Dual beyerdynamic control units chosen for Berlin court install26 February 2016
Linner Elektronik has installed beyerdynamic Orbis control units in the two largest courtrooms of the Berlin Regional Court.
The systems were installed in close cooperation with the beyerdynamic project management department and is the first time two Orbis systems have been connected into one large system within one courtroom. In addition, two different types of microphone were specified, the gooseneck microphone for the judge’s table and Revoluto mics for other participants.
Using a newly developed driver for the Extron media control unit, which was programmed in cooperation with the beyerdynamic conference project management and development departments, two Orbis CU central control units have been combined into one system.
This media control unit was installed in order to monitor the NOM (number of open microphones) and compare them with the other Orbis central control units. In addition, the parameters (e.g. NOM, type of operation, president, etc.) can be determined in the actual media control unit configuration.
Thanks to the media control unit, it is possible for six open microphones to be spoken into simultaneously from some distance in an acoustically challenging room. The open microphones and volume reductions are controlled using a DSP.
As Orbis is based on standard Cat5 wiring, parts of an existing CAT cable network could be used. However, this required four cable lines, which necessitated the use of two central control systems, but this meant the two different microphone types could be installed seamlessly and coordinated.
The Revoluto Classis RM 31 Q microphones were chosen for aesthetic and practical reasons. They are discreetly integrated into the room and, thanks to their distance from the speaker, optimally demonstrate their advantages: volume and freedom of movement while making the best possible use of the available space.
One requirement was that judges have exclusive access to the witness microphone unit. Although this is also integrated into the Orbis conference system and has its own button, its function is limited by the media control unit. Only the judge can switch the witness microphone unit on and off using a keypad with an LED display button.
