The Roland XS-42H is a versatile multi-format matrix switcher engineered to serve as the central routing hub for complex audiovisual systems in corporate, educational, and broadcast environments. Its core function is to provide flexible 4x2 matrix switching, allowing any of its four diverse inputs to be independently routed to either or both of its two outputs. It accepts a wide array of signal types including HDMI, VGA (RGB/YPbPr), and composite video, alongside associated analog stereo audio, making it capable of integrating legacy and modern source equipment into a unified system. This format-agnostic design is crucial for installations where different generations of technology must coexist and interoperate seamlessly.

Beyond simple routing, the XS-42H incorporates a high-quality scaling engine, ensuring that all input signals, regardless of their native resolution or refresh rate, are converted to match the optimal output resolution of the connected displays. This scaling capability guarantees a stable, flicker-free image on screens, eliminating compatibility issues. The switcher also handles audio de-embedding from HDMI sources, extracting the audio to its analog stereo outputs, and can embed analog audio back onto the HDMI output stream, providing comprehensive audio management within the video signal path.

Designed for permanent integration, the unit features a half-rack metal chassis with rack-mount ears included, making it ideal for installation in equipment closets or control racks. Control is facilitated through intuitive front-panel buttons, an included IR remote, and comprehensive RS-232 and IP control for integration into larger control systems like Crestron or AMX. The Roland XS-42H is a reliable, professional-grade solution that simplifies system design, reduces the need for multiple standalone converters and switches, and ensures reliable, high-quality signal distribution in demanding multi-source, multi-display applications.
