Purpose and Compatibility

This LUOM audio extractor pulls sound from a television HDMI ARC port and converts it to optical, coaxial or 3.5 mm analogue outputs. It is intended for owners of ARC-equipped displays who need to feed a soundbar, amplifier or powered speakers that lack an HDMI input.

Sustained Operation

The aluminium chassis dissipates heat during continuous playback and the built‑in digital noise reduction maintains a clean signal over long sessions. Multi‑channel audio exits all outputs simultaneously with no perceptible delay, and the device operates driver‑free once powered via the supplied USB‑C cable.

Decisive Specification

The extractor accepts sampling rates of 32, 44.1, 48, 96 and 192 kHz at 24‑bit depth and handles PCM 5.1 and LPCM 2.0 channel formats. The 3.5 mm jack is limited to PCM and LPCM stereo, so systems requiring multichannel analogue output cannot use this connection.

Questions about this item

Does the aluminium casing keep the LUOM HDMI ARC Audio Extractor cool during all-day use?

The aluminium alloy shell provides good heat dissipation so the converter stays cool during continuous operation.

Which cables and source equipment must I already have to use this extractor?

You need a TV with an HDMI ARC port, an HDMI 2.0 cable to link it to the converter, and either an optical, coaxial or 3.5 mm cable to reach your soundbar or amplifier.

Will my older 2.0-channel amplifier work with the 5.1-channel PCM signal this device can output?

The extractor supports both PCM 5.1 and LPCM 2.0, so a legacy 2.0-channel amp will receive a compatible stereo signal.
