In this project, Sennheiser has worked with Markus Müller (from the Berlin rental company MM Communications), who pre-configured and supplied the wireless systems, specifically the systems 9000 digital 96 channels for the two semifinals and the final of the festival.

These microphones have been used in parallel with the series wireless monitoring systems 2000, with a total of 40 transmitters and some 160 receivers, along with eight other wireless systems for broadcasting from the press center.

As Müller points out, “the quality of the new Digital systems 9000 from Sennheiser is incredible; It is linear in its operation , Transmission quality is as good as a cable system.

Before installing the equipment, This microphone had to pass strict tests, such as working in both transmission modes: High definition with uncompressed audio transmission and long range mode with a codec that increases range under difficult transmission conditions.

“Both modes work perfectly,” says Müller.- and achieve impressive results with their individual ranges. HD mode is certainly superior in terms of audio quality in technical measures, although the differences are barely audible in live situations”.

According to this expert, The main distinction between the two modes is in their scope; "in 'full definition' in HD mode we have achieved a range of up to 250 m. in tests without loss of audio quality, which is impressive, even comparing it directly with analog wireless systems”.
