Marshall Electronics VMV-402-3GSH 3G-SDI Quad Viewer/Switcher

The Marshall Electronics VMV-402-3GSH is a seamless 4x1 video switcher and quad viewer for presentation, control-room, and remote-production workflows. It accepts four 3G-SDI sources, with HDMI available on inputs 1 and 2, then provides simultaneous SDI and HDMI program outputs plus a dedicated HDMI quad-view preview.

An internal scaler handles mixed input formats and frame rates, converting them to the selected program format for consistent output. HDMI program and preview signals scale up to UHD resolution, while the SDI program output supports up to 1080p60. Full-time quadview, a four-source split display, simplifies source monitoring without requiring four separate displays.

Front-panel controls and an Ethernet browser provide direct system configuration without a dedicated application. Ethernet and RS-232 support source selection and quad-view labeling for integration with professional control systems. A metal 1U rack-mounting enclosure suits flypacks, classrooms, conference rooms, courtrooms, production facilities, and other installed AV environments.
