Kramer VS-48UHD 4x8 Matrix Switcher — 4K60 4:2:0 with Embedded Audio

The Kramer VS-48UHD is a high-performance 4x8 matrix switcher designed to deliver flexible, reliable distribution of 4K@60Hz HDMI signals with embedded audio across multi-display environments. Built for professional AV setups such as control rooms, corporate conference centers, educational facilities, broadcast studios, and high-end home theaters, this matrix switcher combines robust signal processing with practical routing versatility. It enables you to select any one of four HDMI sources and route it to any or all of eight outputs, making it a scalable solution for complex installations where configurations may need to adapt to varying room layouts and presentation needs. The VS-48UHD is engineered to protect signal integrity over longer runs, thanks to integrated reclocking and equalization, ensuring pristine video quality and synchronized audio across all connected displays. Its HDCP-compliant design helps ensure compatibility with protected content devices, from Blu-ray players to streaming media players, while the embedded audio features support flexible sound routing to match your AV workflow. This combination of performance, adaptability, and reliable audio-video handling makes the VS-48UHD an essential component for any professional AV rig aiming for consistent, picture-perfect distribution in real-world environments.

• Flexible 4x8 matrix routing: Route any one of four HDMI sources to any or all eight outputs at the same time. This enables seamless distribution to multiple displays, with the ability to tailor signal paths to room layouts, presentation needs, or event flow without repeatedly re-wiring or swapping cables.
• 4K60/4:2:0 support for modern displays: The VS-48UHD is designed to handle ultra-high-definition HDMI signals at 4K@60Hz with 4:2:0 chroma subsampling, delivering sharp detail, smooth motion, and broad compatibility with contemporary 4K displays and projectors while maintaining efficient bandwidth usage.
• Signal integrity via reclocking and equalization: Built-in reclocking and equalization help compensate for cable length, impedance variations, and other transmission challenges. This ensures consistent image quality and stable color fidelity even when routing signals across moderate to long cable runs.
• HDCP-compliant for protected content: The matrix switcher is designed to work with HDCP-protected sources and displays, supporting a wide array of devices from streaming players to Blu-ray players, while maintaining a smooth, interference-free viewing experience.
• Flexible embedded audio routing: The VS-48UHD includes an adaptable audio scheme that accommodates embedded HDMI audio and supports routing choices that fit your audio workflow, simplifying integration with external audio systems and loudspeakers where needed.

How to Install Kramer VS-48UHD

Installing the VS-48UHD is straightforward and tailored for professional environments where reliable performance is critical. Begin by planning your layout so that the four HDMI sources (such as media players, set-top boxes, or computers) are connected to the VS-48UHD inputs. Next, connect the eight HDMI displays or projectors to the eight outputs on the matrix, mapping each display to the appropriate output based on your room configuration and presentation needs. Ensure that power is connected to the unit and that all sources and displays are powered on. Once connected, use the control interface to configure routing: select the desired source for each output, or create preset routing configurations to switch between common presentation scenarios quickly. If your installation includes audio requirements beyond embedded HDMI audio, configure the embedded audio routing to align with your sound system, speakers, or external processors. Finally, test each route by initiating playback from each source to verify video and audio alignment, ensuring that each display receives the correct content and that audio remains synchronized across outputs. For maintenance, keep the unit in a clean, well-ventilated cabinet or rack, away from sources of heat or humidity, and periodically check connections to ensure longevity and consistent performance.
