🔹 Product Name

KAMEHA KA198 Pro 4×4 HDMI Matrix 4K60Hz with HDBaseT 150M & Audio – 1U Rackmount System

---

🔹 Product Description

The KAMEHA KA198 4×4 HDMI Matrix with HDBaseT 150M is a professional-grade AV distribution system designed for long-distance 4K signal transmission. Supporting full 18Gbps bandwidth, this matrix routes four HDMI sources to four HDMI outputs, with each HDMI output mirrored to a corresponding HDBaseT CAT output for simultaneous long-range transmission.

Using a single Cat5e/6/7 cable, the HDBaseT outputs can extend signals up to 150 meters (492ft) for 1080p and up to 120 meters (394ft) for 4K60, maintaining ultra-clear 4K@60Hz (4:4:4) resolution.

Each output supports independent 4K → 1080P downscaling, making it ideal for mixed-resolution environments. The system also features audio de-embedding (balanced analog + coaxial), IR matrix control, and multiple control options including Front Panel, IR Remote, RS-232, LAN, and Web GUI.

Built with a 1U rackmount metal chassis and OLED front display, the KA198 is engineered for conference halls, hotels, campuses, command centers, and LED wall projects requiring reliable long-distance transmission.
