The Roland VR-50HD Multi-Format AV Mixer integrates an audio mixer, video switcher, multi-viewer touch screen 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 features four video input channels, which are fed by 12 inputs, and supports SD, HD, and computer-based signals. The mixer supports either NTSC or PAL standards, with selectable frame rates, and will scale input video to match the selected output resolution.

The VR-50HD features four SDI inputs that support SD/HD/3G-SDI signals, two RGB/Component video inputs, two composite video and four HDMI inputs, as well as 12 analog audio input channels. Built into the front of the mixer is a 7" LCD touch-screen multi-view display that shows the four input sources as well as displays a red border on the active input source. You can set up and control the unit through the touch screen interface. The unit has a designated HDMI output that will send the multi-view display to an available HDMI monitor. The PGM output is available through SDI/HDMI/ and RGB/Component streams. It is also available via the USB output, which you can bring into an available computer or encoder to stream live. The VR-50 features two built-in full-resolution picture-in-picture channels, and you can layer the four inputs to make one composite in addition to the picture-in-picture channels.
