  • 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
