HDMI audio extractor for 4K sources

The Boxwave HDMI audio extractor separates the audio stream from an HDMI signal and sends it to an AV receiver through optical or 3.5 mm connections. It is designed for source devices that lack a dedicated audio output such as Blu-ray, DVD or HD players. The adapter does not support ARC or eARC and a TV cannot be used as the input source. Power is drawn from any 5 V USB port.

Sustained 4K signal handling with HDCP 1.4

The unit maintains a stable link at up to 10.2 G bandwidth with HDCP 1.4 compliance. It passes 4K resolution at 30 Hz in RGB or YUV 4:4:4 colour. Fire TV, PS4 and PS5 sources are limited to 1080p signals and will not output 4K through this extractor. Low energy consumption allows continuous operation from a standard USB power source without thermal throttling.

Three audio modes select the output format

A hardware switch chooses between 2.0 CH for 3.5 mm PCM stereo, 5.1 CH for optical DTS 5.1 surround and PASS mode when the first two modes produce no audio or video. The optical output supports DTS 5.1 while the 3.5 mm jack supports PCM 2.0. The extractor does not support 7.1 channel audio.

Questions about this item

Does the extractor add noticeable heat or fan noise when it runs continuously from a USB power source?

The adapter draws power from a 5 V USB port and is described as low energy consumption with no fan, so it stays cool and silent during all-day use.

Which cables and power source must I already have to connect a source, a display and an audio system?

You need an HDMI cable for the source, another HDMI cable for the display, either a TOSLINK optical cable or a 3.5 mm stereo cable for audio, plus a 5 V USB port or USB power adapter to run the unit.

Will a 1080p-only console still send video through the extractor to a 4K display when the audio mode is set to 2.0CH?

Yes, the extractor passes 1080p signals through its HDMI 1.4 path at up to 10.2 Gbps while the 2.0CH mode delivers stereo PCM over the 3.5 mm jack.
