Audio Extraction Capability

This YINGHUA unit separates audio from an HDMI source and delivers it through optical, coaxial and 3.5 mm analogue outputs while passing the video signal onward to a display. It handles resolutions up to 4096×2160 at 30 Hz and supports 8, 10 and 12-bit deep colour formats. Compatible audio formats include DTS-HD, Dolby TrueHD, DTS, Dolby AC3 and DSD. The device is powered by an external 5 V adapter supplied with a Micro USB cable.

Who This Suits

Gamers and home-theatre users who need to route sound from a console or PC to a legacy amplifier, soundbar or headphones that lack HDMI inputs will find the three audio outputs convenient. The 30 Hz 4K limit makes it unsuitable for anyone requiring 4K at 60 Hz or higher refresh rates for competitive gaming or high-frame-rate video playback. Buyers who need to switch multiple HDMI sources should look at a dedicated matrix or switch instead.

Deciding Specification

The maximum video bandwidth of 3 Gbps and 30 Hz refresh ceiling at 4K resolution determine whether this extractor fits a given setup. If the source device outputs 4K at 60 Hz or demands HDMI 2.0 bandwidth, the converter will not pass the signal correctly. Verify the source refresh rate and resolution requirements before purchase.

Questions about this item

Does the box include everything I need to connect a PS4 to a projector and optical speakers, or must I buy extra cables?

The package includes the converter, a Micro USB cable and a manual. You must supply your own HDMI cables for the PS4 and projector, plus an optical or 3.5 mm audio cable for the speakers.

My source outputs 4K at 60 Hz — will this unit pass that signal through untouched?

The converter supports video up to 4096×2160 at 30 Hz. A 60 Hz 4K signal exceeds that limit, so you would need a device rated for higher bandwidth.

The spec lists 3 Gbps bandwidth and 300 MHz — what does that mean for the picture on my 4K monitor?

Those figures cap the video path at 4K 30 Hz with 8/10/12-bit deep colour. The monitor will receive the full 4K resolution but only at 30 frames per second.
