Combine switching, audio mixing, and USB streaming into a single device, and you get the Roland VR-4HD HD AV Mixer. Four channels of HD video and 8 channels of audio can be mixed down with preview and program (main) video outputs with minimal fuss. Advanced digital processing removes many of the hurdles of a professional A/V setup, and consumer-friendly HDMI, VGA, composite, XLR/TRS, and RCA inputs support readily available video and audio equipment. The USB output lets you take advantage of HD video streaming over the web using popular streaming platforms or advanced multi-source videoconferencing and offers the ability to record straight to your hard drive for distribution.

The interface on the VR-4HD features both tactile controls and a touchscreen for an intuitive and comprehensive control surface where all necessary controls are at the operator’s fingertips. Physical faders offer precise audio adjustment, while the built-in multi-view LCD features a touch interface for accessing set-up parameters and adjusting picture-in-picture settings with simple swiping gestures

The XI-DVI DVI-I Expansion Interface from Roland is meant for use with the V-1200HD Multi-Format Video Switcher.
