Kramer VS-44UHDA: 4x4 4K60 HDMI Matrix Switcher with Audio Embedding/De-Embedding

Meet the Kramer VS-44UHDA, a high-performance 4x4 HDMI matrix switcher designed for demanding AV installations. Engineered to handle 4K@60Hz signals with 4:2:0 chroma subsampling, this matrix gives you flexible routing, dependable signal integrity, and seamless audio management in one compact chassis. Whether you’re equipping a conference room, classroom, control room, or home theater, the VS-44UHDA makes it simple to distribute four HDMI sources to four displays while preserving pristine video quality and crystal-clear audio. With embedded and de-embedded analog audio capabilities, you can tailor your audio workflow to meet the exact needs of your space, ensuring every presentation, video conference, or immersive display is delivered with professional-grade sound and video fidelity.

• 4x4 HDMI matrix routing: The VS-44UHDA can route any of four HDMI sources to any or all outputs simultaneously, delivering flexible distribution for multi-display setups and complex AV environments. This enables you to create independent zones or synchronized presentations without swapping cables or resorting to multiple switches.
• 4K60 4:2:0 video support: Handle modern high-resolution content with confidence. The matrix supports 4K resolution at 60 Hz with 4:2:0 chroma subsampling, balancing bandwidth needs with color performance to deliver sharp, vibrant images on compatible displays and projectors.
• Audio embedding and de-embedding: Seamlessly manage audio between HDMI and analog domains. The VS-44UHDA embeds analog audio into HDMI outputs and can de-embed HDMI audio for analog playback, enabling you to route audio to external amplifiers, mixers, or dedicated sound systems without extra adapters.
• Signal integrity with reclock and equalization: The unit reclocks and equalizes signals to combat common issues caused by long cable runs or HDMI handshakes, helping maintain consistent video timing and reducing jitter, dropout, and artifacts across all outputs.
• HDCP-compliant and reliable operation: Designed to work with protected content in modern AV networks, the VS-44UHDA adheres to HDCP requirements to ensure smooth playback of copy-protected sources while delivering dependable performance in education, corporate, and digital-signage environments.

How to install Kramer VS-44UHDA

• Plan your layout: Position the VS-44UHDA in a suitable rack or shelf area with clear access to inputs, outputs, and the control interface. Ensure adequate ventilation and space for cooling.
• Power connections: Connect the unit to a stable AC power source using the supplied power adapter. Verify that power is stable before proceeding with connections.
• Connect video sources: Attach your four HDMI sources (Blu-ray players, media players, PCs, conference room codecs, etc.) to inputs 1 through 4 on the rear panel. Use high-quality HDMI cables to minimize signal loss.
• Connect displays: Run HDMI cables from outputs 1 through 4 to your displays, projectors, or video walls. If you’re distributing a single source to multiple displays, connect multiple outputs accordingly.
• Set up audio routing: If you plan to embed analog audio into HDMI or extract audio from HDMI for external amplification, connect the required analog devices to the intake/output paths designated by the matrix (as per your installation needs). Ensure any required external analog audio gear is powered and ready.
• Control and configuration: Power on the VS-44UHDA and use the front-panel controls to establish initial routing. For integrated control within larger systems, wire the appropriate control interfaces (IR, RS-232, or compatible control systems) according to your system’s architecture. Test each input-to-output path to confirm both video and audio are routed correctly.
• Fine-tuning and testing: Validate video timings, color fidelity, and audio synchronization across all connected displays. Make any necessary EDID-related adjustments or routing customizations to ensure smooth operation in your environment.
• Documentation and backups: Record your final routing matrix and any control macros or presets for future reference. Create a backup of your configuration to expedite recovery in case of changes or maintenance.
