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:
• phase locked loop (PLL) synthesizer
• function of keys
• 8 digit LED display
• two LED bargraph displays
• true diversity
• monitoring
• squelch threshold
• description fields
• stand-by
• storage of all receiver parameters (e. g. receiver frequencies) in a
permanent memory
During diversity operations, the microprocessor controls every one of the
two receiver chains that are combined on one module.
The receiver parameters and the selectable frequencies can easily be
changed with the help of a conventional computer system as every
receiver module incorporates an additional service interface. Changes
are only possible within the admissible RF bandwidth.
The software can easily be adapted to your individual requirements and
updated at any time by Sennheiser’s Service Department. Our
servicemen simply replace the PROM in the receiver modules.
