4K 60Hz HDMI Audio Extractor Converter - Audio SPDIF + 3.5MM Output

In this review the 4K 60Hz HDMI Audio Extractor Converter is judged as a practical tool for users who need to split HDMI video from audio for older stereo amps or multi-channel receivers. The bottom line: it reliably passes high-resolution video up to 4K 60Hz and extracts digital audio to SPDIF or analog 3.5mm when the source is set to PCM, making it ideal for AV setups that require discrete audio outputs without changing the display chain.

Key Features

• 4K 60Hz video pass through: Supports HDMI 2.0b and HDCP 2.2 to maintain 4K 50/60Hz video to a compatible display for crisp picture quality.
• High refresh 1080p support: Handles 1080P at 120Hz and 144Hz, useful for high refresh monitors or PC output where motion clarity matters.
• Audio extraction options: Converts HDMI audio to 2CH analog stereo via 3.5mm or to multi-channel SPDIF for connection to soundbars or receivers.
• Dolby Digital/DTS passthrough: Passes these digital formats via SPDIF but does not decode them for the analog output, which requires PCM from the source.
• Advanced audio handling: Supports high-bit-rate audio pass through and sample rates up to 192kHz for compatibility with higher quality audio streams.
• HDR and CEC support: Passes HDR10 and supports CEC bypass when used with compatible cables and displays.

Who It's For

This converter is best for home theater hobbyists, gamers, and AV installers who need a compact way to separate HDMI video and audio without replacing existing audio gear. It suits anyone connecting a modern HDMI 2.0 source to a 4K display while routing audio to an SPDIF-capable receiver or a 2CH analog input when the source outputs PCM.

It is not the right choice for users who expect in-unit decoding of Dolby Digital or DTS to analog stereo, or for those using older HDMI 1.2 sources, certain legacy set top boxes, or Apple TV 3rd Generation, where compatibility is explicitly limited.

Pros & Cons

Pros

• Maintains high video quality up to 4K 60Hz with HDCP 2.2 support.
• Flexible audio outputs: 3.5mm analog and SPDIF multi-channel passthrough.
• Supports high sample rates and HDR10 pass through for modern content.
• Easy to set up and generally reliable in everyday use.

Cons

• Does not decode Dolby Digital/DTS to analog, so analog output requires the source be set to PCM.
• Not compatible with some legacy devices such as Apple TV 3rd Generation and certain cable boxes.

Our Verdict

The HDMI Audio Extractor Converter is a sensible value for anyone needing reliable video pass through and discrete audio outputs without surprises. It keeps picture and digital audio integrity for modern 4K setups, but buyers must ensure their source can output PCM for analog use or use SPDIF for pass through of Dolby Digital/DTS. For its price and feature set it is a practical, no-frills solution for many AV needs.

Frequently Asked Questions

Will this decode Dolby Digital or DTS to stereo?
It will pass Dolby Digital and DTS via SPDIF but will not decode those formats to analog; set the HDMI source to PCM for 3.5mm stereo output.

Is it compatible with Apple TV and cable boxes?
It works with many sources like Apple TV and Chromecast, but is not compatible with Apple TV 3rd Generation (Model A2843) or some Comcast Xfinity boxes.

Does it support HDR and high refresh rates?
Yes, it supports HDR10 and high refresh rates including 1080P@120Hz and 1080P@144Hz, and 4K 50/60Hz when used with HDMI 2.0 cables.
