MV-821-HDBNC Multiviewer
Space-saving 2 RU Standalone Multiviewer
The MV-821-HDBNC is a high-density 12G-capable multiviewer that’s perfect for applications requiring space-saving solutions yet still the highest quality image display.
The MV-821-HDBNC multiviewer is part of the MV-8 series multiviewer range. It is small and compact but with a high-density I/O and the only multiviewer to offer 48 inputs and 12 outputs in a 2 RU chassis. This makes the MV-821-HDBNC ideal for on-the-road productions, flyaway packs, houses of worship and conference and events.
