Introduction The wireless Mikroport multi-channel sound transmission system EM 1046 is a transmitter/receiver system in a modular design. It offers comfortable handling and can be relied on for dependable service.
T echnical overview 1 Computer control 1.1 Diversity 1.2 HiDyn plus ® noise reduction 1.3 Block diagrams 1.4.
Every single EM 1046 RX receiver module has an in-built micro- processor for the RF section, the operating elements and all indicators. It serves to control the following components or parameters: •.
Diversity 1.2 Every EM 1046 RX receiver module operates on true diversity. An antenna splitter, integrated into the chassis, serves to route the antenna signals from both antennas to the three receiver modules.
HiDyn plus ® 1.3 »HIDYN plus ® « NOISE REDUCTION SYSTEM The »HIDYN plus ® « noise reduction system serves to reduce the effects of RF interference fields. It increases the signal-to-noise ratio and gets close to about 110 dB for peak modulation.
