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.
The receiving antenna not only receives direct electromagnetic waves, but also reflections from walls, windows, ceilings and other installations, which results in the cancellation of these waves,
as most transmitters are used for portable applications, the „field strength gaps“ then occur in other positions. The effects of field strength variations can only be eliminated through the use of true diversity techniques.
Sennheiser’s specially developed diversity system is based on two receivers operating on the same frequency and two separate antennas. A comparator ensures that the receiver with the strongest RF signal is automatically and noiselessly switched to the AF output. Diversity operations can compensate for considerable variations in field strength, thus providing an enormous gain in transmission reliability.
Nota bene: Every single EM 1046 RX receiver module incorporates two receivers for diversity operation.
