The Roland VR-400UHD is a sophisticated, all-in-one professional streaming and production AV mixer engineered to handle the demanding requirements of modern 4K Ultra High Definition workflows, from live event production to multi-destination streaming. This unit functions as a centralized hub, combining a powerful video switcher, a professional digital audio mixer, a hardware streaming encoder, and a multi-view monitoring system within a single, rack-mountable chassis. It is equipped with a comprehensive array of inputs, including multiple 12G-SDI and HDMI ports that support native 4K resolution at 60 frames per second, allowing for the seamless integration of high-resolution cameras, computers, and media servers. The mixer features advanced video processing capabilities such as seamless transitions, picture-in-picture effects, multiple downstream keyers for graphics, and real-time color correction, enabling broadcast-quality production from a hardware-based, stable platform.

A defining feature of the VR-400UHD is its integrated, hardware-based streaming engine designed for professional live distribution. It can encode the final program output into high-quality H.264/AVC or H.265/HEVC streams and broadcast them simultaneously to multiple destinations, including popular CDNs and social media platforms like YouTube and Facebook Live, via a wired Ethernet connection. This multi-stream capability ensures content reaches diverse audiences across different services without the need for an external computer or software encoder. Complementing its video prowess is a fully-featured 20-channel digital audio mixer with XLR inputs, phantom power, and comprehensive processing including EQ, dynamics, and effects, allowing audio from microphones, instruments, and embedded sources to be perfectly balanced and synchronized with the video.

Designed for reliability in critical live environments, the VR-400UHD offers intuitive control through a responsive touchscreen interface, physical faders, and dedicated buttons, and can be managed remotely via a web browser or integrated into larger control systems using IP and RS-232 protocols. With its ability to handle native 4K signals, produce polished live mixes, and stream directly to the internet, the Roland VR-400UHD is a comprehensive solution for broadcast facilities, large houses of worship, corporate communications, and major live event production companies seeking a robust, all-in-one system for the highest quality live production and distribution.
