Brief description
With the EM 3031-U and EM 3032-U receivers, Sennheiser offers the professional user high
quality RF receivers with a high level of operational reliability and ease of use. The EM 3031-U
and EM 3032-U receivers together with the suitable hand-held and pocket transmitters permit
wireless transmission with studio quality sound. Due to further optimised PLL and microprocessor
technology and the Sennheiser patented HiDyn plus® noise reduction system, these transmission
systems surpass the signal-to-noise ratio and dynamic range of modern CD productions. The true
diversity technology of the EM 3031-U and EM 3032-U receivers ensures interference-free
transmission and minimises the drop-outs in the RF path.
Especially for small television studios and theatres, the simultaneous use of several EM 3031-U /
EM 3032-U receivers is an economical alternative to technically more sophisticated and therefore
more expensive multi-channel systems.
Variants
EM 3031-U:
Single-32-channel true diversitiy receiver
EM 3032-U:
Two-32-channel true diversitiy receiver
Note
EM 3031-U and EM 3032-U differ in the fact that the EM 3032-U contains two
complete true diversity receivers in a single 1 U rack housing. These two receivers
are powered by a common mains power supply unit and via a common pair of
antennæ (antenna splitter integrated).
This manual is therefore always restricted to the description of just one receiver,
the operation of the second receiver in the EM 3032-U is similar.
