Müllermusic Is "DD Ready" – As One of the First Event Technology Service Providers in Germany

Sennheiser supported müllermusic to prepare their wireless equipment for the so called "Digitale Dividende" (DD). Therewith the Cologne-based company for rental sound sytems is – as one of the first event technology service providers in Germany – "DD ready" and already uses the new frequency ranges.


In the near future the yet used frequency ranges to operate wireless microphone systems (790-814 MHz + 832-862 MHz) will be replaced step by step by "LTE", the new mobile phone technology standard. Any company that wants to make sure to broadcast free of disturbances caused by LTE will have to switch their equipment by 2011 to the newly assigned frequency ranges. Theoretically the old ranges stay open to wireless microphone systems untill the end of the year 2015, but in fact first disturbances caused by powerfull LTE-transmitters will occur starting end of 2010.


To be able to use the new frequency range, it is necessary to register at German Federal Network Agency. Most companies additionaly have to adapt their equipment to the new standard. Sennheiser supports its customers during the conversion by providing guidance and service as well as products, that are optimized for the use within the new frequenzy ranges. One of the first customers to be supported by Sennheiser during configuration of the new system and registration of the new frequencies was müllermusic Veranstaltungstechnik GmbH, from Cologne. General manager Franz Josef Khalifeh states: "In agreement with our responsible project-team we have decided to use Sennheiser-technology, because of their expertise in conversions of frequency-ranges, as for example from VHF to UHF. The consulting of Sennheisers customer engeneering, as well as their back office, was very proficient and conclusive."


Usage of the full new frequency range possible


Additionally the technology and products of Sennheiser convinced Mr. Khalifeh. and his team. The hardware of the 2000-product-range is perfectly adapted to the new environment of frequencies. To the technical-project-managers it was mainly important to be able to use the full 75 MHz range of the system. Müllermusic uses 50 transmission-systems of the 2000-product range (including hand- and pocket transmitters), as well as eight InEar-Monitoringsystems of the same product range. "Identical menu-guidance, the comfortable maintenance of all system-components through Sennheisers WSM-software and, last but not least, the high acceptance of Sennheisers HF-technology throughout our customers were decisive in order to make our decision," Khalifeh says.


"We are happy to have truly convinced müllermusic with our 2000-series. Now the company is ready – as one of the first in Germany – to use the new frequencies very secure and free of stress and müllermusic is able to offer its customers a perfect technology, free of any interference caused by LTE-transmitters", adds Sebastian Schull, Sales Director Music Industry & Live Sound bei Sennheiser.
