HDMI ARC Audio Extractor

This LUOM adapter extracts audio from a television HDMI ARC port and converts it to optical, coaxial and 3.5mm outputs for soundbars, speakers or home-theatre receivers. It supports 192KHz sampling rates at 24-bit depth and handles PCM 5.1 and LPCM 2.0 channel formats.

Bundled power cable and manual

A Type-C power cable is included so the unit can operate without drawing power from the TV port. The supplied manual explains the simple plug-and-play connection that requires no driver installation on any device.

TV must have ARC port

The extractor only functions when the source television provides an HDMI ARC connection; without that port the adapter cannot receive an audio signal. Note that the 3.5mm jack outputs stereo PCM or LPCM only, not multi-channel formats.

Questions about this item

Does the 3.5mm jack need any special care since it only carries PCM/LPCM audio?

The 3.5mm output is a standard stereo jack; no special maintenance is required beyond keeping the connector clean and seated firmly.

Which output hits its bandwidth ceiling first when running 192KHz 24-bit audio continuously?

The optical and coaxial digital outputs both support the full 192KHz 24-bit stream, so neither hits a limit before the other under sustained use.

How warm does the aluminum alloy shell get and does the fan make noise during all-day playback?

The aluminum shell provides passive heat dissipation and the unit has no fan, so it runs silently with only gentle warmth during extended operation.
