The Roland VR-4HD is a compact, all-in-one audio-video production mixer that combines multiple critical functions into a single, portable unit, making professional live streaming and recording accessible and straightforward. It integrates a 6-input video switcher, a 4-channel audio mixer, a multi-view display, and a hardware streaming encoder, eliminating the need for a separate computer or complex software setup to go live. Designed for ease of use, its interface features dedicated physical faders, knobs, and buttons for controlling video transitions, audio levels, and stream settings, allowing operators to manage a production in real time with tactile precision and immediate visual feedback.

Central to its design is the built-in multi-touch LCD screen, which serves as both a live multi-viewer for monitoring all video sources and a touch interface for adjusting settings, applying picture-in-picture effects, and operating the downstream chroma keyer for graphic overlays. The unit accepts a variety of video inputs including HDMI and composite, and it provides multiple outputs including HDMI program and preview feeds. Its integrated audio mixer can handle both embedded audio from video sources and analog inputs via XLR and 1/4" jacks, complete with phantom power for condenser microphones, ensuring professional-grade sound to match the video quality.

The VR-4HD is engineered as a complete mobile production station for content creators, educators, corporate presenters, and houses of worship. With its direct USB streaming output to a computer and built-in Wi-Fi for control via a tablet, it offers flexible workflow options. By consolidating switching, mixing, monitoring, and encoding into one robust hardware device, it provides a reliable, "just works" solution for creating polished multi-camera live videos and broadcasts without the instability often associated with software-only setups.
