The Roland V-4EX is a compact, professional 4-channel digital video mixer designed for live production, streaming, and presentation applications. It builds upon the foundation of the V-4 series by adding enhanced features and connectivity, making it a versatile hub for creating dynamic multi-camera productions. The mixer supports four HDMI inputs, allowing users to connect cameras, computers, media players, and other HD sources, and switch between them seamlessly with a variety of transitions, including cuts, fades, and picture-in-picture (PiP) effects. A key upgrade is the inclusion of a dedicated HDMI output for a multi-view display, which shows all connected sources simultaneously on a single screen, greatly simplifying camera monitoring and source selection for the operator.

Beyond video, the V-4EX integrates a capable 4-channel audio mixer. This allows for blending of audio embedded in the HDMI sources with two dedicated external microphone/line inputs (featuring XLR/TRS combo jacks). This enables the addition of live commentary or external music to the program mix. The audio section includes individual level controls, basic EQ for the mic inputs, and a master output control, ensuring balanced and clear sound synchronized with the video. The mixer also features a prominent, bright Tally light system on the front panel to indicate the live source, and it provides remote Tally outputs to drive lights on connected cameras, a critical feature for multi-camera productions.

Designed for ease of use and portability, the V-4EX features a straightforward layout with dedicated buttons and knobs, minimizing the learning curve. Its rugged metal chassis is built for reliability in mobile setups. The unit outputs a clean, switched HDMI program feed for recording or display. While it does not have a built-in streaming encoder like some larger Roland models, its high-quality HDMI output can be easily connected to an external USB capture device or hardware encoder for streaming. The Roland V-4EX is an ideal all-in-one solution for educators, corporate presenters, worship teams, and content creators who need a reliable, user-friendly tool to produce professional-looking multi-camera video with synchronized audio.
