Cascadable single-cable multi-
switches for distribution of digital Sat-
IF signals (4 Sat polarities; including 
HDTV) and terrestrial signals via 
one cable to up to four receivers in a 
single-family household 



No limitation of programme variety - 
transmission of the complete 
programme range of one satellite 



Option to select horizontal/vertical, 
low/high band as well as 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) 
 



Conform 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 1541, EXR 2541, EXR 2554, 
EXR 2558, EXR 2542 or EXR 2581 
can be combined as desired. Up to 
8 multi-switches can be cascaded 
 



For indoor installation
 



Single-cable multi-switch with one 
connection for four receivers, NCF 
18 power supply unit for LNB supply



Low power consumption due to 
high-effi 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 input. All other inputs are 
voltage-free 



Single-cable multi-switch loop-
through to extend the system by a 
single-cable connection for up to four 
receivers
