The Roland VR-4HD is a compact, integrated audio-visual production mixer designed to simplify the creation of professional live video streams, recordings, and presentations. It combines video switching, audio mixing, and digital streaming into a single, portable unit with an intuitive hardware interface, making it accessible for content creators, educators, corporate communicators, and houses of worship. The mixer supports four independent HDMI video inputs, allowing the connection of cameras, computers, media players, and gaming consoles. Its core video functionality includes seamless transitions, picture-in-picture effects, and downstream keying for overlaying titles or graphics, enabling dynamic multi-source video production without the complexity of software-based solutions or large broadcast consoles.

On the audio side, the VR-4HD features a dedicated four-channel mixer with XLR and 1/4-inch inputs, each equipped with phantom power, gain control, and a three-band EQ. This allows for the integration of microphones, musical instruments, and line-level audio sources, which can be mixed independently of the video signals. A critical feature is its built-in USB audio interface and video streamer, which outputs a finalized program mix—combining the selected video source and mixed audio—as a single USB video class (UVC) and audio class (UAC) stream. This enables a computer to recognize the mixer as a standard webcam and microphone input, allowing for direct integration with popular streaming software, video conferencing platforms, or recording applications without requiring additional capture cards or drivers.

The device is built around user-friendliness, featuring a bright multi-view display that shows all input sources and the program output simultaneously, tactile faders and knobs for immediate control, and assignable shortcut buttons for storing and recalling frequent setups. Its all-in-one design eliminates the need for external scalers, audio mixers, and capture devices, providing a streamlined workflow for producing polished live events. Whether used for live streaming to platforms, recording to an external storage device via its USB port, or sending a feed to a projector or display, the Roland VR-4HD serves as a complete production studio in a box, empowering users to produce high-quality AV content with reliability and ease.
