SMATV & Multiswitches
BMS-0512C
19" rack-mount SAT-IF multiswitch, 5 in / 12 out, cascadable up to 7 units
Distribute satellite and terrestrial signals to up to 12 receivers with low trunk loss and dual redundant power supplies — and scale simply by cascading up to 7 units in one 19" rack chain.
Overview
The VIZOBOX BMS-0512C is a professional 19" rack-mount (1 RU) SAT multiswitch for high-performance signal distribution in demanding SMATV head-ends. It combines one SAT position with 4 inputs and an active terrestrial path, feeding 12 receiver outputs plus trunk outputs for cascading up to 7 devices. Lossless sharp filtering across 950–2150 MHz (SAT-IF) and 47–870 MHz (terrestrial), average trunk loss below 2 dB, gain adjustment via potentiometers and selectable LNB powering (13/18 V, 22 kHz, up to 2.5 A) make it a reliable backbone for digital head-end installations.
Highlights
- 12 receiver outputs from one SAT position (4 inputs) plus active terrestrial path
- Cascadable up to 7 devices via 4 trunk outputs + terrestrial trunk
- Dual redundant industrial power supplies with automatic diode-based failover
- Selectable LNB powering (13 V / 18 V / 22 kHz, up to 2.5 A total), QUAD LNB compatible
- Low average trunk loss (< 2 dB), high output isolation and gain adjustment via potentiometers
- Compact 19" / 1 RU design with output port protection up to 100 V and per-output LED indicators
