What it does and who needs it

This HDMI ARC to optical audio converter extracts sound from a TV ARC port and sends it to a soundbar or home-theatre system through a Toslink cable. It supports 24-bit 192 KHz PCM 2.0 audio and includes a 6.6 FT cable for flexible placement. The unit is powered by USB and requires no drivers or software installation.

Sustained-load behaviour

The adapter continuously extracts the digital audio stream from the ARC connection and converts it to optical without compression or added latency. Because it handles only PCM 2.0 streams, the data rate remains constant during long viewing sessions and the converter maintains the same 192 KHz sampling performance throughout.

Thermals noise and power draw

The device draws its operating power from a standard USB port and has no internal fan, so it runs silently and adds negligible heat to an AV cabinet. With no moving parts and a low-power conversion chip, normal use produces no audible noise and minimal thermal load.

Questions about this item

Does the adapter draw enough power to heat up when left running all day?

The unit is powered through a USB connection and uses digital noise reduction to extract audio cleanly, so it stays cool during continuous use.

What must I already own to make this converter work with my soundbar?

You need a TV with an HDMI ARC port, an optical cable for the soundbar, and a USB power source such as a TV USB port or charger.

Will this work if my TV only has a regular HDMI output and not ARC?

No, the converter only accepts an HDMI ARC input and cannot extract audio from a standard HDMI or eARC port.
