KAMEHA KA083 4×2 HDMI Matrix Switch 4K2K (HDMI 1.4 Audio Extraction 3D Support)

Product Introduction

The KAMEHA KA083 4×2 HDMI Matrix Switch is a compact and versatile HDMI routing solution designed to distribute four HDMI sources to two HDMI displays independently or simultaneously.

This true matrix system allows any of the four input sources to be routed to either output display. It can also function as a splitter, enabling the same source to be displayed on both screens at the same time.

Supporting up to 4K×2K resolution (3840×2160 @30Hz) and full 3D HDMI, the KA083 is ideal for home entertainment, conference rooms, digital signage, and professional AV systems.

Product Description

The KA083 provides flexible signal routing with advanced audio extraction capabilities. It allows analog R/L stereo audio and digital SPDIF audio to be extracted directly from the HDMI signal.

With support for HDMI 1.4, Deep Color 12-bit, and HDCP compliance, the unit ensures stable and high-quality video and audio transmission.

The device supports HDMI/MHL dual-mode input (Input 1), enabling compatibility with smartphones and MHL-enabled devices.

Compact in design and surface-mountable, the KA083 is perfect for installations requiring reliable switching in limited spaces.
