Single-cable multi-switch for a single-cable connection
for 6 receivers
Single-cable multi-switch for distribution of digital Sat-IF
signals (four sat levels; including HDTV) and terrestrial
signals via a single cable to up to six receivers in a
single-family household
No restriction on the variety of channels - the complete
range of channels from a satellite is transmitted
Independent horizontal/vertical selection, low/high
selection and transponder selection by each receiver
Changeover between horizontal/vertical and between
low band/high band, together with transponder
selection is carried out in the multi-switch under the
control of the receiver using a special DiSEqC™
command set to EN 50494
For transponder selection special tuner modules called
SCRs (Satellite Channel Routers) are incorporated
within the single-cable multi-switch for conversion to
the subscriber frequencies
Each receiver is assigned a
fi
xed subscriber frequency
(a twin receiver requires two subscriber frequencies)
The unit satis
fi
es EN 50494, i.e. all components of a
single-cable system that satisfy this standard can be
installed in a satellite system
Con
fi
gurable gain in the SAT band with integral pre-
emphasis enables optimum signal distribution to the
subscriber connections
Terrestrial signals can be received in the 5-862 MHz
band even when the satellite receiver is switched off

Installation and safety instructions
The LNB remote feeding is supplied by the receiver via
the “horizontal low” input. All other inputs are voltage-
free. When all receivers are switched off, the system
requires no power
To achieve a continuous power supply to the LNB
(for instance for cascading with loop-through multi-
switches), there exists the option of connecting the
NCF 18 plug-in power supply unit (not included with
this product) to the socket marked “DC”.
For indoor installation
