4x1 HDMI 2.0 4K@60Hz Switcher with Audio Extractor ARC Function, 4 In 1 Out HDMI Selector with SPDIF Coaxial 3.5mm Jack Audio Output for PS3 PS4 Apple TV HDTV Projector Home Theater System

This 4-in-1-out HDMI 2.0 switch with professional audio extraction and ARC function is an upgraded multi-functional audio and video control hub ideal for home theater, living room entertainment and small conference room AV system management. It allows you to connect up to four different HDMI signal sources simultaneously, and switch between any input channel freely, effectively eliminating the hassle of repeatedly unplugging and reinserting HDMI cables when switching game consoles, set-top boxes and media players.

Fully compliant with HDMI 2.0 protocol and HDCP 2.2 content encryption standard, the switch supports ultra-high definition 4K resolution at 60Hz refresh rate, HDR high dynamic range imaging, and is fully backward compatible with 1080P Full HD, 720P and 3D stereoscopic video signals. The built-in high-performance signal processing chip optimizes signal equalization and anti-interference processing, greatly reducing signal attenuation, picture flicker, color distortion and audio-video sync delay during long-distance transmission via HDMI cables.

The core highlight lies in its multi-form audio separation module. It can decode digital audio signals from the HDMI video stream and output through three independent ways: optical SPDIF port, coaxial port and 3.5mm analog audio jack. You can directly connect to power amplifiers, sound bars, active speakers and headphones without occupying the audio interface of your television, realizing lossless Hi-Fi audio decoding for movies and games. In addition, the ARC audio return channel function enables the audio from the TVs built-in apps to loop back to your external audio equipment through the HDMI output port, building a complete surround sound home theater system.

The device supports mainstream lossless audio formats including Dolby TrueHD, DTS-HD Master Audio, LPCM and PCM stereo, delivering immersive layered sound effects for blockbuster films and immersive gaming. It features ultra-broad device compatibility, perfectly matching PlayStation 3, PlayStation 4, Apple TV, Blu-ray DVD players, desktop and laptop PCs, TV boxes, HD smart TVs and office projectors.

Adopting plug-and-play design without driver installation, the compact solid plastic casing ensures stable heat dissipation during long-term continuous operation. The internal shielding structure resists external electromagnetic interference to guarantee consistent picture and sound quality. It is a cost-effective and practical AV accessory for home audio-visual enthusiasts, retro game players and families pursuing upgraded television sound effects.
