The Roland VR-3EX is a compact, all-in-one audio-video mixer designed for live streaming, webcasting, and multimedia presentations, integrating video switching, audio mixing, and live effects into a single portable unit. It enables users to create professional-looking live video productions by combining multiple video sources—such as cameras, computers, and media players—with synchronized audio. The mixer is particularly well-suited for applications in education, corporate communications, houses of worship, and online content creation, where ease of use and a streamlined production workflow are essential.

The system provides several key video inputs, including HDMI and composite, allowing the connection of various video devices. Its built-in digital video effects, picture-in-picture capabilities, and transitions allow operators to enhance productions dynamically without requiring external processing hardware. The integrated audio mixer features multiple XLR and line-level inputs with phantom power, basic EQ, and level controls, enabling the combination of microphones, instruments, and playback audio directly within the unit. A notable feature is the inclusion of a USB video interface, which allows the mixed output to be sent directly to a computer as a webcam signal for seamless integration with streaming software.

Housed in a durable, portable chassis with an integrated carrying handle, the VR-3EX is designed for setup and operation by a single user. The control surface is laid out intuitively, with dedicated buttons and faders for video selection, audio mixing, and effects triggering. By consolidating video switching, audio mixing, and streaming output into one device, the Roland VR-3EX simplifies the technical challenges of live production, making professional multimedia broadcasting accessible to a broad range of users.
