EXR 2508

Cascadable multiswitches for distribution of four satellite levels and terrestrial signals to many receivers
Only one down conductor is required per receiver (two down conductors for twin receivers)
Independent horizontal/vertical, low/high selection from any receiver
Switching takes place via the coaxial cable with 14/18 V and 0/22 kHz signal frequency
Integrated amplifier for low connection losses in the satellite range
Preemphasis for equalization of cable attenuation integrated
Reception of the terrestrial range possible even when the satellite receiver is switched off
Terrestrial range: 5-862 MHz passive
High decoupling between outputs
Remote power supply possibility via the input horizontal low. All other inputs are voltage-free (thus operation with UAS 585 possible)
For indoor installation
Multiswitch for eight connections, with integrated power supply unit
Low power consumption due to highly efficient, short-circuit-proof switched-mode power supply and power-saving concept (each individual multiswitch branch is supplied by the connected receiver and switched off when the receiver is switched off)
Cascadable with EXR 2554/2558
Kathrein Power Saving: The LNB supply is switched off as soon as no receiver is active on the EXR 2508 or in the cascade.
This function can be deactivated, e.g. if pass-through multi-switches without Kathrein Power Saving are used in the cascade
