4 in 1 Out HDMI 2.0 Switch with Audio Extractor, 4K@60Hz HDR 4-Port HDMI Switcher Support ARC, IR Remote Control and HDCP 2.2, HDMI Signal Selector for PS3 PS4 Laptop PC HDTV Projector

This 4×1 HDMI 2.0 switcher is a practical multi-device audio-video switching solution, which integrates HDMI signal switching, independent audio extraction and ARC audio return functions in one compact device. It can connect up to four HDMI signal sources simultaneously, including PS3, PS4 game consoles, desktop & laptop computers, DVD players, set-top boxes and media players, and freely switch the signal output to one HDTV, monitor or projector, effectively reducing repeated plugging and unplugging of HDMI cables and organizing messy home entertainment wiring.

Compliant with HDMI 2.0 specification and HDCP 2.2 copyright protection protocol, it delivers 18Gbps ultra-high transmission bandwidth, stably outputs 4K@60Hz ultra-high definition resolution, and fully enables HDR10 high dynamic range image optimization and 3D stereoscopic video playback, restoring rich color details and layered visual effects for movies and games.

The highlight is the independent audio extraction module and ARC return channel function. It can separate embedded digital audio from HDMI video signals and output to external sound bars, power amplifiers and speakers; the ARC channel realizes two-way audio transmission with ARC-compatible TVs, directly transmitting TV audio back to your audio equipment without extra audio wires, building a complete home surround sound system.

Two control methods are available for flexible operation: you can press the physical button on the device panel for manual switching, or use the matched infrared remote controller to toggle input channels remotely from your sofa. It also supports intelligent auto-switching mode, which automatically locks the signal of the newly powered-on device for more convenient daily use.

Adopting plug-and-play design without driver installation, the internal circuit adds anti-interference shielding to avoid signal attenuation, picture flicker and audio lag during long-time continuous operation. It is widely applied in home living room entertainment systems, small meeting room presentation switching, game room multi-host display control and family home theater audio-visual integrated setup.
