The VM3250 Modular Matrix Switch Gen. 2 offers advanced access and real-time control of multiple local and remote A/V input devices and displays from a single chassis. The VM3250 allows users to independently switch and route video and/or audio content directly to various monitors, displays, projectors, and/or speakers from the front panel pushbuttons. A built-in Scaler encodes the video format in order to provide seamless, real-time switching. The front panel LCD shows a quick view of active port connections. The switch also includes an option to select an EDID Mode that yields the best resolution across different monitors.
Boasting a sophisticated and reliable design that delivers the best audio/visual distribution and control, the solution also incorporates an Award-winning GUI that can be accessed from anywhere over a network or the internet. Through the intuitive web interface, video sources can be previewed in real-time via live streaming and video walls can be easily set up. A calendar-based scheduling function allows you to queue and play connection profiles via a calendar view for a set period of time, reducing related operation costs.
The VM3250 is easily expandable and accommodates a lineup of hot-swappable ATEN I/O boards. Equipped with automatic signal conversion, it allows various combinations of digital and analog video interfaces, including Fiber Optic, HDBaseT, DisplayPort, HDMI, DVI, 3G-SDI, and VGA. The flexibility and expandability make it ideal for large-scale A/V applications such as broadcasting stations, traffic and transportation-related control rooms, emergency service centers, and any application that requires customizable, high-speed A/V signal routing.
