Sennheiser A 9000 Antenna
Sennheiser A 9000 Antenna – The remote-controlled antenna booster contains eight highly selective filters that each allow a 24 MHz frequency window to pass. This adds significant safety to the system, as unwanted signals are blocked directly before the first active component. The frequency window can be remotely selected from the receiver. The linear RF amplifier with very high resistance to intermodulation can compensate for cable losses of up to 14 dB.
The booster and receiver together check the cable loss on the RF cable and adjust the gain automatically. The A 9000 omnidirectional antenna incorporates the AB 9000 booster, which is directly mounted on the surface of the antenna.

About the Sennheiser Digital 9000 System
The Digital 9000 system has been developed for all professional users in broadcast studios, theatres and live performances unwilling to comprise on sound. Its unique uncompressed digital audio transmission offers artefacts free sound with great dynamics.
The use of extremely steep filters allows a very narrow set-up of the respective radio frequencies within the available frequency range without risking intermodulation. With its intuitive handling and comprehensive feature list, including e. g. 12 different microphone heads to choose from, the Sennheiser Digital 9000 system not only delivers a unique sound quality but also lets its professional users experience a whole new kind of flexibility.
