HDMI Audio Extractor for 4K 60Hz Sources

The LUOM OZV8-1 splits one HDMI input into a pass-through HDMI output plus separate digital optical and 3.5 mm analogue audio outputs. It handles video up to 4K at 60 Hz with 18 Gbps bandwidth and supports HDR10 and ARC. The unit requires the included 5 V 1 A power adapter to operate. It suits users who need to send audio to a soundbar or AV receiver while keeping the video path intact.

Passive Aluminium Housing Runs Silent

The extractor has no fan and draws a maximum of 350 mA from the supplied DC adapter, so it adds no audible noise to a living-room or desktop setup. Its aluminium shell dissipates the small amount of heat generated during normal operation without any active cooling. Power consumption stays low because the device only processes signal extraction and format conversion, not video scaling or amplification.

18 Gbps Bandwidth Decides Compatibility

The single specification that determines whether this extractor fits a build is its 18 Gbps maximum throughput. That bandwidth carries 4K 60 Hz 4:4:4, 1080p at 120 Hz or 144 Hz, and deep-colour formats up to 36-bit. Sources or displays that demand higher bandwidth — such as 4K 120 Hz or 8K signals — will not work through this device. Buyers needing those rates must choose a higher-bandwidth solution.

Questions about this item

How do I connect the extractor between my 4K 60 Hz source and display, and which port do I plug the 5 V power adapter into?

Connect the source to the HDMI input, the display to the HDMI output, then insert the included 5 V/1 A power adapter into the DC5V socket before powering on; the unit will not pass signal without external power.

Does the optical SPDIF or 3.5 mm jack wear out and need replacement after extended use?

Both audio outputs are solid-state with no moving parts; they do not degrade under normal use and no scheduled replacement is required.

What is the maximum cable length I can run at 18 Gbps before the 4K 60 Hz HDR signal becomes unstable?

The specifications list a maximum input and output cable distance of 10 m using AWG26 HDMI standard cable at the full 18 Gbps bandwidth.
