The Roland VR-50HD is an all-in-one AV Mixer with output for web streaming and recording. It integrates an audio mixer, video switcher, multi-viewer touch screen and USB video/audio streaming into a stand-alone device. The video side of the VR-50HD includes a 12-input, 4-channel multi-format video switcher that includes a still store channel for graphics, logo or frame capture. Inputs can be 3G/HD/SD SDI, HDMI, RGB/component and composite. The audio section is equally impressive with a 12-channel digital audio mixer with inputs from analog sources or embedded in the 4 SDI or 4 HDMI inputs. The USB 2.0/3.0 output enables web streaming and recording by simply connecting to the USB port of a computer. This portable live HD production solution is ideal for schools, churches, council meetings, corporate events, sports, trainings, or any production live to web.
