Sat-IF distribution system (4 x sat-IF)
single-cable multi-switch
Features
Cascadable single-cable multi-switch for distribution
of digital Sat-IF signals (4 sat levels; including HDTV)
and terrestrial signal for supplying 4 receivers in single-
family households
No restriction on the variety of channels - the complete
range of channels from one satellite is transmitted
Option to select horizontal/vertical,
low band/high band and transponder independently
from each receiver
Changeovers horizontal/vertical, low band/high band
and transponder selection is carried out in the multi-
switch, controlled by the receiver with a special SCR
single-cable command set to EN 50494
For transponder selection special tuner modules called
SCRs (Satellite Channel Routers) are incorporated
in 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 satisfi es the SCR single-cable standard to
EN 50494, i.e. all components of a single-cable system
that satisfy this standard can be installed in a
satellite system
Terrestrial signals can be received even when the
satellite receiver is switched off

multi-switches such as the EXR 2558 can be mixed
in any combination. Up to 8 multi-switches can be
connected in a cascade
For indoor mounting
