Roland VR-50HD MK II Multi-Format AV Mixer with USB 3.0 Streaming provides key updates to the already powerful unit that integrates an audio mixer, video switcher, multiviewer touchscreen and USB video/audio streaming into a stand-alone device. This portable live HD production solution combines the functions of a video switcher and an audio mixer, and it is ideal for use at live events, schools, churches, council meetings, and corporate events. The VR-50HD MK II features four video input channels, either SDI, HDMI, RGB/Component, composite, or a combination. It supports SD, HD, and computer-based signals in either NTSC or PAL standards, with selectable frame rates, and will scale input video to match the selected output resolution.
