BS131-8
Cascadable stand-alone 13-in-8 SAT-IF multiswitch with power supply
Distribute twelve SAT-IF signals plus terrestrial to eight subscribers with low insertion loss and reliably clean reception. The integrated power supply and compact housing make installation straightforward in any distribution network.
Overview
The VIZOBOX BS131-8 is a cascadable stand-alone SAT-IF multiswitch that routes 12 satellite inputs and one terrestrial input (passive or active) to 8 user outputs. Built on the latest RF-chipset and stripline technology, it combines an integrated amplifier for low insertion loss with high isolation between polarisations. Subscriber control follows the established standards: 12–14.5 V / 16–19 V for vertical/horizontal, 0/22 kHz for low/high band and DiSEqC 1.0 for Sat A/B selection. An integrated power supply (90–265 VAC) completes the compact unit.
