HDMI 2.0b Audio Extractor

This converter takes one HDMI input and provides one HDMI output plus optical Toslink SPDIF and 3.5 mm stereo outputs. It separates audio from the video stream while passing the picture through unchanged. The built-in analog volume knob adjusts the extracted audio level only. It is suited for users who need to send sound to a separate amplifier or headphones.

Bandwidth and Format Limits

The unit handles 18 Gbps bandwidth with YUV 4:4:4 sampling and supports HDR. HDCP 1.4 and 2.2 are both supported for protected content. Video modes include 4K at 60 Hz and 30 Hz as well as 1080P at 60 Hz and 30 Hz. The HDMI 2.0b interface is backward compatible with earlier HDMI versions.

Audio Output Mode Selection

A PASS CH or 5.1 CH mode switch decides whether the optical output carries stereo or multichannel sound. This single setting determines if the extractor matches your audio system. Buyers who need simultaneous multichannel HDMI and optical outputs should look elsewhere.

Questions about this item

Should I choose the optical Toslink or the 3.5 mm jack for my speaker system?

Use the optical Toslink for digital surround up to 5.1 channels or the 3.5 mm jack for stereo analogue headphones or powered speakers; both outputs are active simultaneously.

Will 4K at 60 Hz actually reach my display through this extractor?

The unit passes 4K at 60 Hz with YUV 4:4:4, HDR and 18 Gbps bandwidth, so the video signal reaches the display unchanged while audio is tapped off.

Does the HDMI 2.0b connection limit the audio formats I can send to the optical port?

HDMI 2.0b carries up to 5.1-channel PCM and compressed bitstreams; the extractor forwards those formats to the optical output in PASS CH or 5.1 CH mode.
