eARC-to-Optical Audio Converter

This AUTOUTLET EFU185CAA unit converts HDMI eARC or ARC signals from a television into an optical audio output. It enables connection of modern TVs to soundbars, home-theatre receivers or wireless headphones that lack an HDMI eARC input. The adapter handles PCM 2.0, Dolby 5.1 and DTS 5.1 formats at up to 24-bit/192 kHz sampling. It is intended for users who need a simple digital-audio bridge without changing their existing speaker system.

Driver-Free Plug-and-Play Setup

Installation requires only connecting the HDMI cable to the TV eARC/ARC port and an optical cable to the audio device. No software, drivers or external power supply are needed, so the link is active immediately. The main issue arises if the TV HDMI port used is not labelled eARC or ARC, or if the TV audio output menu is not set to pass-through mode. CEC control is not supported, so volume must be managed on the audio device itself.

192 kHz 24-Bit Capacity With 5.1 Limits

The converter comfortably handles stereo PCM and compressed 5.1 surround streams such as Dolby Digital and DTS at the full 192 kHz rate. It does not decode or pass through lossless formats like Dolby TrueHD, DTS-HD Master Audio or object-based codecs such as Dolby Atmos. Buyers who want uncompressed multichannel or height-channel audio will need a different solution.

Questions about this item

How can I verify the converter is passing audio correctly after connecting it to my TV's HDMI eARC port?

Connect the optical output to your soundbar or home theatre system, then play content encoded in PCM 2.0, Dolby 5.1 or DTS 5.1; if sound is reproduced at up to 24bit/192KHz without delay, the unit is working as intended.

What is included in the package and what extra cables must I supply?

The box contains the converter only; you must provide an HDMI cable for the TV's eARC/ARC port and a separate optical cable for the audio output.

Which version should I choose if I need to extract Dolby 5.1 or DTS 5.1 from an HDMI eARC source?

This model EFU185CAA supports eARC/ARC to optical conversion with PCM 2.0, Dolby 5.1 and DTS 5.1 at up to 24bit/192KHz, so select it for those formats.
