4-Port HDMI 2.0 Switch with Audio Extraction

This 4-input 1-output HDMI 2.0 switch connects up to four source devices to a single display while extracting audio to separate optical and 3.5 mm outputs. It handles 4K at 60 Hz with HDR and HDCP 2.2 compliance for protected content. The unit includes an IR remote for convenient switching from a distance.

Check display and source compatibility before

Verify that your TV, projector or monitor accepts 4K 60 Hz signals over HDMI 2.0 and that each source device outputs within the 18 Gbps bandwidth limit. Ensure your soundbar or AV receiver has an optical Toslink input for digital surround or a 3.5 mm analogue input for stereo. The switch requires a free HDMI output port on the display and four HDMI cables for the sources.

Replaces manual cable swapping and basic splitters

This unit upgrades from repeatedly unplugging HDMI cables or using a passive switch without audio separation. The jump is worth it when you need Dolby Atmos 7.1 CH or DTS soundtracks sent to an external audio system while keeping 4K 60 Hz video on the display. It also solves EDID-related black-screen issues with its adjustable EDID mode.

Questions about this item

Does the switch come with the IR remote and HDMI cables, or do I need to buy cables separately?

The package includes the switch unit and an IR remote for wireless input selection; HDMI cables for the four inputs and the single output are not supplied and must be purchased separately.

When should I use the optical SPDIF output versus the 3.5 mm jack for my sound system?

Use the optical Toslink port to send Dolby Atmos and 7.1-channel surround sound to an AV receiver or soundbar; use the 3.5 mm stereo jack for simpler two-channel analogue connections such as powered speakers or headphones.

Will 4K at 60 Hz HDR content pass through without signal loss on a 1080p display?

The switch handles 4K 60 Hz HDR at 18 Gbps bandwidth with HDCP 2.2, and its adjustable EDID mode resolves resolution mismatches so a 1080p display receives a compatible signal without black-screen issues.
