4K HDMI Switch with Audio Extraction

The ESTONE OZQ9 is a four-input, one-output HDMI switch that adds audio extraction through optical, coaxial and 3.5 mm analogue outputs. It suits anyone connecting several 4K sources to a single display while sending sound to a separate amplifier or soundbar. The ARC-enabled HDMI output also returns audio from a compatible TV back to the extractor ports.

Thermals and Power in Normal Use

The unit ships with a 5 V 1 A DC adapter, so power draw stays low and no active cooling is required. In typical operation the aluminium enclosure remains cool to the touch and the device runs silently. No fan noise or thermal throttling occurs during extended 4K 60 Hz sessions.

Bundled Accessories and Software Impact

A credit-card-style IR remote lets you switch inputs from the sofa without touching the box. The included 5 V power supply is mandatory for reliable 18.5 Gbps bandwidth at 4K 60 Hz; without it the switch may fall back to lower resolutions. No software or drivers are needed — the device is purely hardware-based.

Questions about this item

How do I connect the 5 V 1 A power adapter and the four HDMI sources so the switcher passes 4K 60 Hz without signal drop?

Plug the included 5 V 1 A DC adapter into the unit first, then connect up to four HDMI 2.0b sources to the input ports and the display to the HDMI output; use certified HDMI 2.0b cables no longer than 3 metres for 4K 60 Hz or 5 metres for 4K 30 Hz to stay within the 18.5 Gbps bandwidth limit.

Which audio output will need attention first — the optical Toslink, the coaxial or the 3.5 mm jack — and what should I check?

The optical Toslink and coaxial ports handle ARC return audio while the 3.5 mm jack and L/R outputs only extract audio; inspect the Toslink cable for dust or bent tips if surround formats such as Dolby TrueHD or DTS-HD stop passing through.

At what cable length does 4K 60 Hz 36-bit colour start to fail on the HDMI output?

With HDMI 2.0b cables the 18.5 Gbps link supports 4K 60 Hz up to 3 metres; beyond that distance the 600 MHz per-channel bandwidth drops out and you must lower the resolution to 4K 30 Hz to reach 5 metres.
