Mikroport body-pack transmitters
Information
The SK 50 UHF and SK 250 UHF Mikroport body-pack trans-
mitters are designed for the frequency range from 450 - 960
MHz. Within a switching bandwidth of 24 MHz, up to 16
channels can be selected. In combination with a microphone,
the Transmitter can be used as a cordless Microphone. To
reduce interference and to improve the signal-to-noise ratio, SK
50 UHF and SK 250 UHF transmitters are equipped with the
"HiDyn Plus" noise reduction system. In combination with a
Receiver which is also equipped with this system (e.g. EM
1046), a link can be established which is characterised by
excellent operational reliability and superb transmission
quality.
