Multi-channel receiver EM 9046 SU Sennheiser

Flexible, digital transmission with superior audio quality and ease-of-use
The new EM 9046 multichannel receiver is destined to become the reference standard throughout the broadcast and theatre production industries, like the legendary EM 1046 that came before. The EM 9046 incorporates up to 8 digital receiving channels, each with 328 MHz of switching bandwidth covering the UHF spectrum from 470 to 798 MHz. A highly intuitive, icon-based user interface provides a complete system overview via a large TFT display. Designed for maximum spectral efficiency, the EM 9046 can safely accommodate as many as 40 channels within a 24 MHz frequency window. Complex intermodulation calculations are no longer necessary - operating frequencies can now be evenly spaced. A broad variety of connection options allow for easy integration into existing audio and IT infrastructure. Receiver modules can also be exchanged for upgrade and maintenance, making DIGITAL 9000 a future-proof investment.

FEATURES

• Fast setup and easy operation with an excellent system overview
• 8-channel modular receiver system – tuneable between 470 and 798 MHz
