🔹 Product Name

KAMEHA KA220 Pro 8×8 HDMI Matrix 4K60Hz with HDBaseT 150M & Audio – 2U Rackmount System

---

🔹 Product Introduction

The KAMEHA KA220 8×8 HDMI Matrix with HDBaseT 150M is a professional long-distance 4K AV distribution system designed for large-scale installations. Supporting full 18Gbps bandwidth, it routes 8 HDMI sources to 8 HDMI outputs, with each HDMI output mirrored to a corresponding HDBaseT CAT output, enabling simultaneous transmission to up to 16 displays.

Using a single Cat5e/6/7 cable, HDBaseT outputs extend video transmission up to:

• 150 meters (492ft) for 1080P

• 120 meters (394ft) for 4K60

Delivering true 4K@60Hz (4:4:4) resolution, the KA220 ensures crystal-clear image quality with HDR support. Each output features independent 4K → 1080P downscaling, ideal for mixed display environments.

With audio de-embedding, IR matrix control, and multiple control interfaces, this 2U rackmount matrix is engineered for hotel ballrooms, university campuses, command centers, and enterprise AV projects.
