Sat-IF distribution system
Features

Cascadable single-cable multi-
switches for distribution of digital Sat-
IF signals (8 Sat polarities; including 
HDTV) and terrestrial signals via one 
cable to up to eight receivers in a 
single-family household

No limitation of programme variety 
- the complete range of programmes 
of both satellites is transmitted 

Option to select horizontal/vertical, 
low/high band, Sat position A/position 
B and transponder from each 
individual receiver  

Switching (horizontal/vertical), low/
high band, Sat position A/position B 
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  

Reception of terrestrial range is 
also possible when the receiver is 
switched off 
 

Settable gain in the Sat range 
enables optimal signal distribution to 
the subscriber connection 

Single-cable multi-switch EXR 1981 
and multi-switch loop-through EXR 
2998 can be combined as desired. 
Up to 8 multi-switches can be 
cascaded 

For indoor installation 
EXR 1981

Single-cable multi-switch for a single-
cable connection for 8 receivers, with 
an integrated 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 is thus 
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 for system extension by a
