Multiswitches

Cascadable multi-switches for distribution of eight Sat polarities and terrestrial signals to many receivers
Only one drop cable is required per receiver (for twin receivers two drop cables are required)
Option to select horizontal/vertical, low band/high band Sat position A/B independently from each receiver due to DiSEqC™ control
If the receiver is not DiSEqC™ controlled, switching bet- ween horizontal/vertical, low/high is on Sat position A; with Tone Burst Sat position A/position B is additionally possible
Integrated amplifier ensures low tap losses in the Sat-IF range
Integrated pre-emphasis to equalise the cable loss

Terrestrial signals can be received even when the satellite receiver is switched off
Terrestrial range: 5-862 MHz, passive
High inter-output isolation
LNB remote feeeding over the inputs horizontal low. All other inputs are voltage-free (thus enabling operation with the UAS 585)

For indoor installation EXR 2908
Multi-switch for eight connections, with integrated power supply unit
Low power consumption due to highly efficient, short- circuit proof switched-mode power supply unit and energy- saving concept (each multi-switch line is powered by the receiver connected to it and is thus switched off whenever the receiver is switched off)


Cascadable with EXR 2998 EXR 2998
Multi-switch, loop-through, for system extension by eight connections each
Highly cascadable (up to 40 connections)
