Cascadable single-cable multi-switch for distribution of
digital Sat-IF signals (4 Sat polarities; including HDTV)
and terrestrial signals to supply 2 x 4 receivers in
single-family households
No limitation of programme variety - transmission of the
complete programme range of one satellite
Independent selection of horizontal/vertical, low/
high band, Sat position A/position B as well as of
transponder from each receiver
Switching (horizontal/vertical, low/high band) and
transponder selection take place in the multi-switch,
controlled by the receiver with a special SCR single-
cable command set in conformance with EN 50494
For transponder selection, the single-cable multi-
switches are equipped with special tuner modules
called SCRs (Satellite Channel Router) which effect
conversion to subscriber frequencies
A
fi
xed subscriber frequency is assigned to each
receiver (twin receivers require two subscriber
frequencies)
Conforms to SCR single-cable standard EN 50494, i.e.
all components of a single-cable system that conform to
this standard can be integrated in a Sat system
The terrestrial range can also be received when the
satellite receiver is switched off
EXR 2542 single-cable multi-switches and EXR 2558
loop-through multi-switches can be combined as
desired. Up to 8 multi-switches can be cascaded
For indoor installation
suitable for DVB-T

Single-cable multi-switches
Features
EXR 1542
Single-cable multi-switches for two single-
cable connections for 4 receivers each, with an
integrated power supply unit for LNB supply
Low power consumption due to high-ef
fi
ciency,
short-circuit proof switched mode power supply
unit and energy-saving concept (the single-
cable multi-switch is powered by the receiver
connected to it and switched off whenever the
receiver is switched off)
LNB remote feeding via horizontal low inputs.
All other inputs are voltage-free
EXR 2542
Single-cable multi-switch loop-through to
extend the system by two single-cable
connections for 4 receivers each
