4 In 1 Out HDMI 2.0 Switch with Audio Extractor, 4K@60Hz HDR ARC HDCP 2.2 EDID Dolby Atmos 7.1CH Surround Sound, Optical SPDIF + 3.5mm Audio Output with IR Remote for Home Theater Game Consoles

This 4-port HDMI 2.0 switcher with independent audio extraction function is an all-in-one multimedia control hub optimized for complex home entertainment and audio-visual systems. It features 4 HDMI input ports and 1 HDMI output port, allowing you to connect up to four different devices such as PS5, Xbox Series X/S, set-top boxes, Blu-ray players, laptops and streaming sticks to a single TV or projector, eliminating frequent plugging and unplugging of HDMI cables caused by limited display interface quantity.

Equipped with an infrared wireless remote controller, you can switch between input channels effortlessly from your sofa or recliner, and physical buttons on the main body are also reserved for manual operation when the remote control is unavailable. The core highlight lies in its powerful audio separation module: it breaks the limitation that audio can only be output along with HDMI video signals. It provides two independent audio interfaces, one digital optical SPDIF Toslink port and one analog 3.5mm stereo jack. The optical port transmits high-fidelity Dolby Atmos, DTS and 7.1-channel surround sound to AV receivers, amplifiers and professional soundbars, while the 3.5mm port directly connects headphones and desktop speakers for private listening without disturbing others.

Compliant with HDMI 2.0 standard and 18Gbps high bandwidth transmission, it fully supports 4K@60Hz ultra-high definition resolution, HDR high dynamic range imaging, 3D stereoscopic video, 1080P high frame rate playback and HDCP 2.2 content encryption protocol. The built-in ARC audio return channel realizes reverse audio transmission: when your smart TV plays built-in streaming content, the audio signal can be sent back to your external audio equipment through this switch, avoiding additional audio cables and making the whole home theater wiring neat and orderly.

Multiple EDID adjustable modes are integrated inside the chipset. You can toggle EDID parameters manually to lock fixed resolution and refresh rate, effectively solving common compatibility problems including screen flickering, no signal output, abnormal color display and automatic resolution jumping when switching different devices. The internal signal processing chip ensures seamless channel switching with only a short blank screen transition, zero frame drop, no image lag and no audio-video synchronization deviation, perfectly meeting the high real-time requirements of competitive gaming and ultra HD movie appreciation.

The compact and sturdy casing adopts good heat dissipation design to maintain stable performance during long-term continuous operation. It is a plug-and-play device that requires no driver download, firmware upgrade or complicated system configuration. Widely applied in living room home theater integration, game room multi-device management, hotel guest room multimedia distribution and office conference room signal switching scenarios.
