Key Digital KDX444SP HDMI over 50m CAT6 Extender Set

Key Digital KDX444SP HDMI over 50m CAT6 Extender Set

Looking for a hassle-free way to send 4K video from your source to your display—even if they’re in different rooms? The Key Digital KDX444SP is your go-to HDMI over CAT6 extender set. It’s made to handle 4K/UHD 18Gbps signals with zero fuss, stretching your HDMI connection up to 70 meters (yep, that’s over 230 feet) on standard CAT5e/6 cable. Whether you're setting up a home theater or a commercial AV system, this thing just gets the job done—cleanly and reliably.

Seamless Connections with Full Buffer Tech

Ever plugged in a device and the signal just wouldn’t sync? That’s where Full Buffer Technology on the Key Digital KDX444SP saves the day. This little brain behind the scenes smooths out HDMI handshakes so everything talks to each other properly—your source, your display, and everything in between. It even gives you 16 different EDID options (including an auto setting), which basically means your gear always knows what it’s working with. No more head-scratching when things don’t sync up.

No Signal? Not a Problem—Thanks to Forced Hot Plug Detection

Here’s a neat trick: the forced hot plug detection on the KDX444SP makes sure your devices always know there’s a display waiting for a signal. Normally, if a TV or monitor doesn’t send the right “I’m here” signal, your source just stays silent. But this extender takes control and keeps the communication lines open. It’s like having a friend on the phone yelling, “I’m still here!” so the conversation doesn’t drop.

Crisp, Clear 4K Video at 60Hz (Plus HDR)

If you’re working with high-end content, the Key Digital KDX444SP has your back. It supports full 4K resolution at 60Hz, complete with HDR and 4:4:4 chroma subsampling. Translation: you’re getting smooth motion, rich colors, and stunning clarity. Even if you’re dropping down to 1080p or lower, you’ll still get extra distance—up to 70 meters. It’s like upgrading your HDMI cable to superhero status.

Total Control with IR and RS-232

For the AV techs and control freaks out there (you know who you are), this HDMI extender set also includes IR and RS-232 control ports. That means you can integrate it into pro-level systems and control your gear without running extra cables. Use the 3.5mm IR port or Phoenix connector for RS-232—it’s built for setups that demand flexibility and precision.

Clean Mounting with the KD-SMS16 (Sold Separately)

No one likes a spaghetti mess of cables. Mount the KDX444SP neatly using the KD-SMS16 shelf mount, designed to fit several Key Digital products. It’s the finishing touch to a tidy, professional AV setup—whether you're stacking in a rack or tucking it behind a display.

Let’s be real: when you're dealing with high-res video across long distances, you need gear that won't flake out on you. The Key Digital KDX444SP is built for reliability, control, and clarity, without the headaches. Plug it in, set it up, and let it handle the rest.
