HDMI ARC to Optical Converter

This converter connects an ARC-compatible television to a sound system using a built-in optical SPDIF cable. It is intended for home theatres, meeting rooms and conference spaces where the TV has an ARC port but the audio equipment only accepts optical input. The unit draws power from a USB port on the TV or a charger.

ARC-only compatibility requirement

The converter works exclusively with televisions that provide an HDMI ARC interface; it does not support eARC or standard HDMI ports. Buyers whose TV lacks an ARC-labelled socket cannot use this adapter and will need a different extraction method.

192 kHz 24-bit audio with 5.1 pass-through

The device handles PCM stereo plus Dolby 5.1 and DTS 5.1 formats at a 192 kHz 24-bit sampling rate, provided the connected sound system also decodes those formats. It cannot process higher-channel-count audio such as 7.1 or object-based codecs, so users requiring those formats must look elsewhere.

Questions about this item

What does the 192 kHz sampling rate mean when I connect this converter to my soundbar?

The converter passes audio up to 24-bit/192 kHz from the TV's ARC port to the optical input on your soundbar, preserving the full resolution of PCM stereo or compressed 5.1 streams.

Which HDMI standard does the ARC connection use and what audio formats can it actually carry?

The HDMI ARC link carries PCM stereo, Dolby 5.1 or DTS 5.1; the TV must be set to one of those formats and the sound system must support the chosen codec.

What physical space and connections do I need to install the 1.05 m cable?

You need an HDMI ARC port on the TV, a SPDIF optical input on the speaker, and a USB power source such as a TV USB port or charger; the cable itself is 1.05 m long.
