At IBC, Sennheiser has today unveiled Digital 9000, a digital wireless system that can transmit completely uncompressed audio, artefact-free and with superb dynamics. Targeting broadcasting professionals, (musical) theatres and high-profile live audio events, Digital 9000 sets a new benchmark in digital wireless transmission. The system, which includes the EM 9046 receiver, SKM 9000 handheld and SK 9000 bodypack transmitters, and a comprehensive suite of accessories, has been meticulously designed for the highest channel counts in today’s increasingly dense frequency environment.
“This system is a masterpiece, both in the digital and the wireless realm,’ said Kevin Jungk, portfolio manager for wireless microphones at Sennheiser. “It offers unprecedented sound quality and ease of use. For example, users will no longer have to calculate and circumvent intermodulation frequencies but can conveniently place their transmission frequencies in an equidistant grid.’
The ground-breaking digital wireless system is fitted with two transmission modes to suit any need and environment. The High Definition (HD) mode will transmit entirely uncompressed, artefact-free audio, as if a high-quality cabled microphone were used. The Long Range (LR) mode has been designed for difficult transmission environments with many sources of interference. It ensures maximum range with a proprietary Sennheiser digital audio codec. “This refined codec ensures an audio quality that is superior to that of an FM system,’ explained Kevin Jungk. “These two modes make Digital 9000 the most versatile digital wireless system available, and the best adapted to on-site requirements.’
In addition to IR synchronisation between receivers and transmitters and a convenient antenna loop-through for creating larger receiving systems, Digital 9000 offers a number of unique features. First and foremost, the system does not generate any intermodulation products – the high linearity of the entire system, from transmitters to antennas and receivers, and a special transmitter design make laborious intermodulation calculation a thing of the past. Transmission frequencies can simply be set in an equally spaced grid.
The receiver also automatically measures the RF cable loss between the receiver and the booster and adjusts the gain accordingly. “This makes the RF wireless system easier to operate for users with less RF knowledge,’ concluded Kevin Jungk.
