Two Orbis central control units connected to one overall system – the very first installation in the Berlin Regional Court in courtrooms 500 and 700.

With over 900 employees, the Berlin Regional Court is the largest of its kind in Germany. Located on Turmstrasse 91, it houses numerous courtrooms in which criminal matters are tried. The two largest courtrooms (500 + 700), in which Orbis has been installed, are of great architectural interest and have high-security tracts.

The systems in both courtrooms were installed by Linner Elektronik, the design and planning was carried out in close cooperation with the beyerdynamic project management department. In addition to the use of two different types of microphones, another special feature of this installation is the first ever connection of two Orbis systems into one large system within one court room.

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 logically combined into one system. Generally, any number of Orbis central control systems can be connected using these drivers. However, attention must be paid to the requirements of the relevant project.

In the Regional Court, this media control unit was installed in order to monitor the NOM (number of open microphones) and the Clear and Func functions 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 difficult room. The open microphones and volume reductions are controlled using a DSP (Digital Signal Processor).

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. In addition, the two types of microphone – the gooseneck microphone for the judge’s table and Revoluto microphones for other participants – could be installed seamlessly and coordinated perfectly.

The Orbis built-in microphone units are very discreet thanks to their inconspicuous, flush installation. The easily distinguishable, tactile microphone unit buttons and the headphone connection for assisted listening or relaying a foreign language ensure that the court is also in line with the UN convention on equal rights for disabled people.

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 key pad with an LED display button.

The system has been used successfully in trials since November 2015.
