Roland Professional A/V VR-4HD All-In-One HD AV Mixer

VR-4HD from Roland, an all-in-one AV mixer, integrates a digital audio mixer, video switcher, multi-viewer with touch screen and USB video/audio output streaming all into a stand-alone device.

It's a complete portable HD studio in a single unit, allowing single-person production of sound and video using tactile faders, buttons, and touch screen.The VR-4HD features professional quality Broadcast controls and switches ensuring more accurate, faster operation than interfaces based on a computer-style mouse and keyboard.

Its ability to simultaneously switch video with the push of a button and adjust audio with the adjustment of a fader is invaluable, and puts all essential features right at the operator's fingertips.
