Introduction
Wireless microphone and instrument systems have rapidly become standard equipment for musicians, Sennheiser’s evolution wireless systems are the standard for musicians, broadcasters, theatre produc- tions, reality television shows, and sound contractors alike. Sennheiser is the leading pioneer of wireless systems and over the years created Emmy Award-winning advances in the field of RF wireless technol- ogy. Sennheiser is proud to apply that same technology to the evolution wireless range of products which fit comfortably into virtually any budget. Traditionally, most wireless systems have offered the user a choice of fixed frequencies within a range of available VHF or UHF frequencies. While this ap- proach makes for easy frequency selection, it offers little or no flexibility in circumventing interference or designing complex systems. Sennheiser evolution wireless G3 systems avoid the problems associ- ated with RF (radio frequency) interference by being capable of tuning to a wide range of available UHF frequencies (up to 1,680 tunable frequencies). In addition, evolution wireless G3 systems offer easy and reliable system setup with the “Easy Setup” function. “Easy Setup” allows a receiver to scan the built-in frequency presets, choose a free one, and then program the transmitter over a wireless infrared link. These presets are specifically calculated not to interfere with each other, an undesirable effect which is known by the technical term “intermodulation.” Because of their frequency agility, Sennheiser wireless systems give the user great flexibility to select available frequencies, even in the most com- plex multi-channel setups. This is ever important now and in the future as we see our RF environment populated by digital television stations as well as the likely possibility of other devices utilizing the UHF RF spectrum.
In addition, Sennheiser wireless systems feature a variety of versatile components and accessories which allow the user to adapt a system to nearly any imaginable need. From small-venue clubs and boardrooms to Broadway stages and stadium-sized concert halls, Sennheiser wireless is used with con- fidence every day by users the world over.
About UHF Wireless Systems
•UHF (Ultra High Frequency) transmission, the most popular format today, op- erates in the 470–698 MHz range. Because of its higher frequency range, UHF is not as susceptible to the interference typical of the VHF range, and is therefore a more stable format. Additionally, UHF systems are more convenient as they have shorter antennas than VHF systems.
