4-Port HDMI 2.0 Switch with Audio Extraction

The ESTONE OZQ4 connects four HDMI 2.0 sources to a single display at 4K 60 Hz. It extracts audio through an optical Toslink port and a 3.5 mm stereo jack, supporting ARC for TV-to-soundbar setups. Compressed formats such as DTS Digital and Dolby Digital pass through without decoding. The unit is powered via an included USB cable.

Check HDMI 2.0 and HDCP 2.2 Compatibility

Verify that each source and the display support HDMI 2.0 and HDCP 2.2 for 4K 60 Hz protected content. The switch handles 480p, 576p, 720p, 1080p and 1080p 3D signals automatically. Audio extraction works independently of the display, so external speakers can be used without a TV connected. Ensure a 5 V USB power source is available near the install location.

Compact Metal Chassis with IR Remote

The black enclosure measures 5.91 by 2.36 by .79 inches and weighs 11.9 ounces, fitting easily behind equipment racks. Four HDMI inputs and one HDMI output are arranged on the rear panel alongside the optical and 3.5 mm ports. An IR remote selects sources or triggers auto-switching to the most recent active input. No external power adapter is included, only the USB cable.

Questions about this item

What cables and accessories come with the OZQ4 and what must I provide?

The box includes the 4×1 HDMI 2.0 switch, an IR remote control without batteries, and a USB power cable without a power adapter. You must supply four HDMI input cables, one HDMI output cable, and a 5 V USB power source.

Which audio output on the OZQ4 should I use for my soundbar — optical or 3.5 mm?

Use the optical Toslink port for compressed formats such as DTS Digital and Dolby Digital, or the 3.5 mm stereo jack for analogue headphones or amplifiers; both can operate independently of the TV.

What does the 18.5 Gbps bandwidth figure mean when I connect a 4K 60 Hz source?

It confirms the switch passes full 4K@60 Hz 4:4:4 HDR video at the HDMI 2.0 limit of 18 Gbps without compression or frame-rate loss.
