5.1ch HDMI 1.4 Audio Extractor

The YINGHUA bw-4kha01 separates audio from an HDMI 1.4 signal and delivers 5.1 channel sound through optical, coaxial and 3.5 mm outputs. It supports 4K resolution at 30 Hz and passes video through to the display. An aluminium alloy shell houses nickel-plated connectors for durability.

Suited for ARC setups, not multi-channel PCM

This extractor suits installations that need ARC support and compressed surround formats such as DTS-HD or Dolby TrueHD. It does not suit users who require uncompressed multi-channel PCM output beyond the listed formats. Builders needing HDMI 2.0 bandwidth or higher refresh rates should consider other options.

HDMI 1.4 limits video to 4K 30 Hz

The single specification that decides compatibility is the HDMI 1.4 interface, which caps video throughput at 4096 x 2160 at 30 Hz. If the source or display requires 4K at 60 Hz or higher bandwidth, this unit will not pass the signal correctly.

Questions about this item

Will the 5.1ch extractor pass 4K 30Hz video to my older 1080p display without downscaling the source?

The HDMI 1.4 link supports 4096×2160 at 30 Hz and will negotiate the highest common resolution, so a 1080p screen receives 1080p while the source still sees a 4K-capable sink.

How can I confirm the ARC return path is active after connecting the optical cable?

Play multichannel content and check the AV receiver or soundbar display — it should indicate DTS, Dolby TrueHD or DTS-HD decoding when ARC is working.

Does the package include an HDMI cable and an optical cable, or only the extractor and power lead?

The box contains the extractor and a 5 V power cable; HDMI and optical cables must be purchased separately.
