Marshall VMV-402-3GSH 4-Input Auto-Scaling, Multi-Viewer Switch

Streamline multi-camera monitoring and live production with the Marshall Electronics VMV-402-3GSH multi-viewer switch. This Pro HDMI switcher consolidates four inputs (four 3G‑SDI sources with HDMI on inputs 1 and 2) and auto‑scales them into a single, consistent output — ideal for broadcast, security and AV monitoring applications. Fast, seamless switching and configurable layouts let operators watch multiple feeds in real time without distracting glitches, while dual program outputs (SDI and HDMI) plus a full-time HDMI quad view support simultaneous distribution to recorders, displays and control rooms. The VMV-402-3GSH is a 1RU rackmount solution built for reliability in remote news vehicles, control rooms, lecture halls and surveillance installations. Easy integration with Crestron, Ethernet or RS‑232 control systems and a web GUI for configuration reduce installation time and simplify automation.
