THE FEDERAL Administrative Court (BVerwG) is the supreme authority for non- constitutional public law matters in Germany. The court is located on the outskirts of Leipzig city centre in the former Imperial Court of Justice building. Alongside the Federal Labour Court, the Federal Court of Justice, the Federal Fiscal Court and the Federal Social Court, the BVerwG is one of the five federal supreme courts of Germany. At the end of 2013, two courtrooms of the BVerwG were equipped with a digital Audio Distribution Network (ADN) conference system from Sennheiser. Studio-Elektroakustik was
given the job of installing the system, as the Federal Administrative Court is a long-standing customer of the Leipzig-based company.

With audio quality of the upmost importance during judicial proceedings, a new conference system proved a welcome investment, writes Tom Bradbury The existing conference
system, which had been in use for many years in the court building, was no longer able to meet today's high demands with regard to audio quality. “The court contacted us
and expressed an interest in a new conference system,” says project manager Andre Scholze. “As a result, we set up a demonstration with the ADN systems. Even after the initial listening tests, the Sennheiser discussion system was able to prove itself beyond doubt. As far as audio quality and speech intelligibility are concerned, the old components and the new solution were worlds apart!”
GRAND SETTING Sennheiser ADN conference systems were installed in two courtrooms. Courtroom IV and the magnificently ornate Grand Historic Courtroom are each equipped with 10 digital discussion units (one ADN C1 and nine ADN D1) permanently installed in the judges’ desks. In addition, there are 15 more discussion units that can be flexibly used when required and which are connected by
the court’s own technical staff. The gooseneck microphones are fitted with a super-cardioid capsule developed by Sennheiser to effectively suppress ambient noise interference. The discussion units are connected by Cat5 cables, with plugs that go into concealed connection sockets. As the cables of the built-in units are laid inside the desks, the optionally available strain relief system (ADN TR1) was not required. A cabled solution was provided in accordance with the explicit wishes of the customer – a wireless system, which would be susceptible to tapping, was ruled out for security reasons. “Wireless communication of any kind, including wireless LAN, is not permitted in the courtrooms,” explains Scholze. As the Sennheiser ADN
discussion units were to be built into the desks, Studio- Elektroakustik commissioned its own team of fitters to carry out the work. “Providing custom-made solutions is a key part of our service,” says Scholze. “For aesthetic reasons alone, the Federal Administrative Court would
not have been happy with discussion units placed on top of the desks.” The discussion units communicate in a network with the digital ADN CU1 central unit, which is connected to an ADN PS power supply unit. The external power supply increases the system’s reliability against failure, as the two double conference ports provide the opportunity
electronically recorded in Leipzig due to unresolved legal issues. For the time being, two court reporters record the spoken word in a written form in the conventional manner. However, Sennheiser ADN Conference Manager software offers the possibility of convenient digital minute- taking at any time. A free app called Sennheiser Easy Control is available for the ADN system, which makes it possible to control and monitor up to 15 discussion units via an iPhone or iPad. The new Sennheiser ADN
conference system was officially put into operation on 5 December 2013, and, in spite of the acoustically challenging environment, has since being guaranteeing optimum speech intelligibility whenever judgements and decisions are delivered.
