What this extractor does

The UTEK 4K HDMI 2.0 Audio Extractor pulls the audio signal from an HDMI video source and sends it to analog stereo or digital optical outputs. It supports resolutions up to 3840 x 2160 at 60 Hz and works with gaming consoles, Blu-ray players and streaming devices. No HDMI display connection is required for the audio outputs to function.

ARC and multi-channel details

The unit includes an ARC mode that routes TV audio back through the extractor when the television has an ARC or eARC port; the TV remote cannot adjust volume while ARC is active. For 5.1-channel sound over the Toslink port, both the source and the connected display must support 5.1CH, otherwise the output falls back to 2CH PCM.

The spec that decides fit

HDMI 2.0 and HDCP 2.2 compliance means the extractor passes 4K 60 Hz protected content, so it suits setups that need to split audio from a modern console or 4K player without downgrading the video signal.

Questions about this item

Will the optical Toslink port on this extractor need replacement after extended use?

The optical Toslink port is a passive connector with no moving parts; it does not wear out and requires no scheduled replacement.

What video bandwidth limit appears first when running 4K at 60 Hz continuously?

The HDMI 2.0 interface caps sustained throughput at 3840×2160/60 Hz, so that resolution ceiling is the first limit reached.

Does the unit generate noticeable heat or fan noise during all-day operation?

The extractor has no fan and draws minimal power, so it runs silently and stays cool even with continuous use.
