BMS51-24-32
Cascadable active SAT-IF multiswitch, 5 inputs to 24/32 outputs
Distribute four satellite polarisations plus terrestrial signals to up to 24 or 32 subscribers from a single unit with integrated power supply. The latest RF-chipset technology and built-in amplification keep insertion loss low and signal quality consistently high.
Overview
The VIZOBOX BMS51-24-32 is a cascadable active SAT-IF multiswitch that routes 4 satellite polarisations (950–2150 MHz) and one terrestrial input (5–862 MHz) to 24 or 32 user outputs. An integrated amplifier ensures low insertion loss, while high isolation between polarisations (30 dB) and integrated pre-emphasis compensate for cable loss in larger distribution networks. Standard 13/18 V and 0/22 kHz control makes it compatible with Quad and Quattro LNBs, and an optional power-saving LNB standby mode reduces operating costs.
