Diversity reception
The EK 3241 operates on the “true diversity” principle:
A receiving antenna receives not only the electromagnetic
waves which reach it by a direct path, but also the
reflections of these waves which are created in the room by
walls, windows, ceilings and fittings. When these waves are
superimposed, destructive interference occurs, which can
also be called “field strength gaps”. Repositioning the
receiving antenna can bring a solution, provided the
transmitter remains in its original position. With mobile
transmitters, however, the “field strength gap” will then
occur with a different transmitter position. These “field
strength gaps” can only be eliminated with true diversity
receivers.
In true diversity, instead of one antenna and one receiver
there are now two antennas and two receiver sections. The
antennas are spatially separated. By means of a
comparison circuit, the receiver section with the strongest
RF signal is always switched to the common AF output. The
risk of the occurrence of “field strength gaps” in both
antennas at the same time is virtually nonexistant.
Information on the compander system
This receiver is equipped with HiDyn plus™, the Sennheiser
noise reduction system that reduces RF interference.
HiDyn plus™ offers extreme operational reliability and
ensures highest transmission quality.
