KAGO HDMI Audio Extractor Splitter 4-in-1 - 4K 60Hz ARC/eARC

In this review of the KAGO HDMI Audio Extractor Splitter, the bottom line is simple: this device suits anyone who needs to combine multiple HDMI sources and feed clean audio to a home theater or soundbar while keeping full 4K@60Hz video. The unit is designed for living rooms and game setups where an external AV receiver or soundbar is required, and it stands out for extracting audio to both RCA and optical outputs while supporting ARC/eARC. Setup is straightforward and the included remote plus manual switch make it convenient to operate from the couch.

Key Features

• 4 HDMI inputs: Lets you connect up to four source devices and switch between them without re-plugging cables, which is handy for consoles and streaming boxes.
• Audio extraction: De-embeds HDMI audio to analog RCA L/R or digital optical SPDIF so you can feed older amplifiers or a soundbar without losing the HDMI video path.
• 4K@60Hz support: Handles up to 4K at 60Hz with HDR10 compatibility when used with HDMI 2.0 certified cables for sharp, high-frame content.
• eARC/ARC passthrough: Supports ARC/eARC to receive higher-channel audio from a TV and route it to your AV system for better sound formats like Dolby Atmos via compatible setups.
• 18Gbps transmission: Uses a powered design and an industrial-grade IC chip to maintain stable video and audio signals with minimal frame loss during gaming or streaming.
• Remote and manual control: Includes an IR remote for couch switching and front-panel buttons with LEDs so you always know which input is active.

Who It's For

This is a good fit for homeowners and gamers who run multiple HDMI devices to one display and want to extract audio to older receivers, soundbars, or optical-only systems. It is particularly useful for players who use consoles like PS5 or Xbox and for PC users who want to route audio separately while preserving 4K video to the TV.

Shoppers who need lab-grade signal routing or professional AV matrix switching should look elsewhere; this unit is aimed at consumer living-room and bedroom setups. Also, if you require guaranteed HDR10 behavior across every cable, plan to use HDMI 2.0 certified cables to maximize compatibility.
