Important Notes Before You Buy

• This extractor uses HDMI 1.4b and supports a maximum video resolution of 4K@30Hz.
• Devices such as PS5, PS4 Pro, and Xbox Series X/S output 4K only when connected to an HDMI 2.0-compliant display — the 4K option will not be available via this extractor for those consoles.
• To receive 5.1CH surround audio, your video source must output a 5.1CH signal.
• This extractor does NOT support HDMI ARC or eARC. Do not connect the HDMI output to an AV receiver for HDMI audio passthrough.

Frequently Asked Questions

Q: Can I use this HDMI audio extractor with a PS5 or Xbox Series X for 4K output?

A: This extractor supports HDMI 1.4b with a maximum resolution of 4K@30Hz. Consoles like PS5 and Xbox Series X require HDMI 2.0 for 4K output, so the 4K pass-through option will not be available for those devices. It will still work for audio extraction at supported resolutions.

Q: What audio outputs does this HDMI audio extractor support?

A: It provides two audio outputs simultaneously: an Optical S/PDIF port for digital multichannel audio (up to 5.1CH when the source supports it) and a 3.5mm AUX stereo port for analog audio. When using the AUX port, be sure to set your source device's audio to PCM 2CH for best results.

Q: Does this extractor support HDMI ARC or eARC?

A: No, this device does not support HDMI ARC or eARC. It is designed specifically to extract audio from an HDMI source signal — you cannot connect its HDMI output to an AV receiver for HDMI audio passthrough.

Q: How is this HDMI audio extractor powered?

A: It is powered via USB (a USB power cable is included in the box). No separate power adapter is needed, making it easy to power from a TV USB port, laptop, or any standard USB charger you already own.
