TG 1000 on the Tagus River: Digital Wireless Technology from beyerdynamic in Lisbon’s Electricity Museum

Lissabon/Heilbronn, July 2013: Not far from the Hieronymites Monastery, a stately brick building rises from the shores of the Tagus river, defining the face of the Belém district: The Electricity Museum (“Museu da Electricidade”) is considered a prime example of Portugal’s industrial culture in the early 20th century. Following on extensive renovations, it has spent the past few years as a popular cultural center and science museum. Reminiscent of a cathedral, the historic, landmarked building is located on the grounds of the former Central Tejo power plant, which supplied electricity to light the Portuguese capital for centuries. The museum is now operated by a foundation owned by the “EDP - Energias de Portugal” energy corporation.

A wide variety of temporary exhibits are held on a regular basis in addition to the main exhibition, which uses original machinery to show visitors the working processes used in the power plant. Theater performances, concerts and conferences are as much a part of the Electricity Museum’s program as lectures on energy – television crews often film specials in the telegenic former power plant.

In spring of 2013, the Electricity Museum was equipped with new sound components. The equipment was supplied by beyerdynamic’s Portuguese partner Garrett Audiovisuais, which also managed the installation of all the components. Special attention was paid to excellent speech intelligibility, because the performance area’s challenging acoustics leave no room for compromise: Acoustically hard walls, ceiling-high windows, bulky metal girders and all kinds of loading cranes, pipes and boilers make up a visually appealing, but acoustically demanding layout.

Based on its positive past experiences, EDP decided once again to use wireless technology from beyerdynamic. EDP chose the new digital TG 1000 system, which is equipped to handle all the Electricity Museum’s special requirements.
Four TG 1000 2-channel receivers are installed in a mobile rack, while two passive WA-ATD wideband directional antennas ensure perfect coverage of the entire area. The system also includes eight TG 1000 beltpack transmitters that are operated using the museum’s previously purchased MCE 10.18 condenser lavaliere microphones, as well as four TG 1000 handheld transmitters, which are equipped with high-quality TG V96w true condenser capsules (cardioid-shaped directional polar pattern).

As a digital 24-bit wireless system, the TG 1000 covers a 319 MHz range of the UHF spectrum, ensuring stable operation, now and in the future. Thanks to the OneButton Navigation and Chameleon software, operating this system is incredibly intuitive. In terms of sound, it features excellent dynamics and impressive sound clarity, and the innovative TriplePlay Codec ensures high error resistance and minimal latency. Even in complex spaces like Lisbon’s Electricity Museum, the TG 1000 offers a wide operating range and optimal sound results.

Duarte Aires, responsible for operating the museum’s event technology, is firmly convinced of the advantages of wireless digital signal transmission: “We’ve been using the TG 1000 since early May 2013, the system has so far exceeded our high expectations during practical applications. The sound quality is flawless, and operation is very simple. We were already familiar with the quality of beyerdynamic products: For many years, we successfully used a beyerdynamic analog wireless system – the new TG 1000 has actually managed to take the many advantages we were already enjoying to an even higher level! Since its installation in the Electricity Museum, the new beyerdynamic wireless system has delivered an ideal performance for a very broad spectrum of events.”
