KanexPro Composite/ S-video to 4K HDMI Converter

The KanexPro CON-AV-HD4K is a versatile universal scaler converter engineered to bridge legacy analog video with modern digital displays. Designed for creators, educators, installers, and home theater enthusiasts, this device converts a single Composite (RCA) or S-video input into a pristine HDMI 4Kx2K@60Hz signal. It’s more than a simple adapter—it’s a sophisticated analog-to-digital processor that adds precision to color, detail, and overall image quality. With intuitive front-panel adjustments, you can tailor brightness, contrast, sharpness, and color fidelity to achieve the most natural and engaging picture from older sources such as VCRs, game consoles, cameras, and legacy DVD players. Whether you’re upgrading a classroom AV setup, restoring retro gaming experiences, or integrating vintage equipment into a modern 4K display, the CON-AV-HD4K delivers dependable performance, predictable results, and a cleaner video image from sources that were never designed for today’s ultra-high-definition screens.

• The heart of the KanexPro CON-AV-HD4K is its robust upscaling engine, which takes standard-definition and standard-definition-with-S-video input and intelligently scales to 4Kx2K resolutions at 60Hz. This means your old content can shine on today’s 4K televisions and projectors, with sharper edges, improved detail, and more accurate color than simple line-doubling methods. The result is a significantly more immersive viewing experience for retro gaming, classic movies, or archival footage, while preserving the original character of the source material.
• Flexible input options ensure compatibility with a wide range of devices. The unit accepts a single Composite (RCA) video input or an S-video input, providing a straightforward, single-source path to HDMI. This makes it ideal for setups where multiple older devices need to be integrated into a modern display without multiple adapters or complicated signal routing. The converter maintains signal integrity from common analog formats, delivering stable performance even when the source signal fluctuates between different composite and S-video standards.
• High-quality HDMI output ensures your upgraded signal looks great on 4K displays. The CON-AV-HD4K transcodes the analog video into a digital HDMI stream capable of delivering vibrant color and crisp detail at 4Kx2K @ 60Hz. This HDMI path lets you leverage the full capabilities of modern TVs, monitors, and projectors, while keeping the original input experience intact. In addition to upscaling, the device emphasizes color fidelity and luminance accuracy, reducing common analog issues such as color bleed, blur, and blocky artifacts that can plague older sources when viewed on 4K panels.
• Front-panel controls put precise image tuning at your fingertips without needing external software or a remote. Adjustments for brightness, contrast, color saturation, and sharpness let you fine-tune the image to taste and room lighting conditions. The front panel interface is designed for quick calibration during live presentations or demonstrations, enabling instant optimization when switching between sources or content types. These controls empower users to extract the best possible image from vintage equipment, ensuring the final result looks intentional and professional on today’s displays.
• Compact, robust design that’s well-suited for professional AV installations, classrooms, studios, and home theaters. The KanexPro CON-AV-HD4K is built to handle everyday use with reliable performance and straightforward integration. Its form factor makes it easy to mount or place in equipment racks, media centers, or on a shelf alongside other AV gear. Clear labeling and a thoughtful control layout reduce setup time, so you can quickly configure, test, and deploy without unnecessary technician intervention.
