SK 5212-II
The versatile bodypack
transmitter SK 5212-II
is inconspicuous and very comfortable to
wear due to its compact design.
The transmission power can be adjusted
to increase transmission duration and
to adapt to regional regulations. The
new Low Intermodulation Mode (“LoI”)
increases interference immunity, espe-
cially during multi-channel operation. The
switching bandwidth of up to 184 MHz,
more than double that of its predeces-
sors, provides extra flexibility. An input
sensitivity range of -30 to +40 dB makes
the transmitter suitable for use in quiet
interview situations as well as with very
powerful singing voices in musicals. The
SK 5212-II requires only one AA battery
for at least 5½ hours of operation and is
available in L, N, N-US and P frequency
variants.

Architects Specifications
It shall be possible to attach a versatile
bodypack transmitter inconspicuously
to clothing due to a compact design.
With a bandwidth of up to 184 MHz, it
shall be compatible with the EM
3731/3732-II true diversity receiver
and have a sensitivity of -30 dB to
+40 dB. Operation shall be quick and
reliable. The bodypack transmitter shall
also be energy-saving with one AA
battery and shall last for at least 5½
hours of operation.
