- 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
