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

Kathrein Power-Saving as used in the cascade

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“.
