Cascadable multi-switch for distribution of four satel-
lite levels and terrestrial signals across multiple
TV/Receiver
Only one downlink per TV/Receiver needed
(two for twin TV/Receiver)
Independent selection of horizontal/vertical, low/high,
for each TV/Receiver
Switchable via the coaxial cable with 14/18 V and
0/22 kHz signal frequency
Integral amplifi er for low attenuation in satellite signal
band
Integral pre-emphasis to equalise cable attenuation
Terrestrial signals also receivable even when sat
TV/Receiver switched o
Terrestrial band: 5-862 MHz, passive
High degree of insulation between outputs
Multi-switches EXR 2558 and EXR 2554, together with
single-cable multi-switches of the EXD and EXE series
can be combined
Up to eight multi-switches can be cascaded
For indoor installation
EXR 2508
Multi-switches for eight ports with power supply unit
for LNB power feed
NCF 18
Low power consumption based on high-e ciency
short-circuit-proof switch-mode power supply unit
Kathrein Power-Saving:
The LNB power feed is switched o as soon as there
are no longer any TV/Receiver active on the EXR 2508
or in the cascade. This function can be deactivated,
for instance if loop-through multi-switches without

„vertikal low“. All other inputs are voltage-free
Sat-IF distribution system (4 x sat-IF)
Multi-switch
Features
EXR 2554 and EXR 2558
Loop-through multi-switch for system extension with
four or eight connections each
Kathrein Power-Saving:
As soon as there are no longer any TV/Receiver active,
a signal is generated at the last multi-switch via the
„vertical low“ trunk. This signal then switches the LNB
power supply o .

Kathrein Power Saving
If an EXR 2508 is operated as a stand-alone device or is operated in conjunction with other multi-switches which bear
the Kathrein Power-Saving logo, Kathrein Power-Saving can be activated when the stand-by switch is set to „ON“. If a TV/
Receiver is included in the cascade, the LNB is supplied from the last multi-switch.
Multi-switches without Kathrein Power-Saving do not generate any signal to the last multi-switch. In order to
ensure an uninterrupted power supply to the LNB, the stand-by switch must be set to „OFF“.
