Audio extraction from HDMI sources

The Monoprice 124278 Blackbird extracts audio from an HDMI video stream and outputs it through analog stereo or digital optical S/PDIF connections. It passes video signals up to 4K at 60 Hz with 4:4:4 chroma and 10-bit HDR. The unit complies with HDMI 2.0b and HDCP 2.2 and delivers up to 18 Gbps video bandwidth.

Installers needing audio breakout without video

This extractor suits integrators who must send audio to a legacy amplifier or soundbar while the display handles the video. It does not switch between multiple HDMI inputs, so buyers who need to select from several sources should consider a dedicated switch. It also does not amplify speaker-level signals, so systems requiring powered speaker outputs will need a separate amplifier.

HDCP 2.2 compliance for protected 4K content

The single specification that determines compatibility is HDCP 2.2 support. Without it, protected 4K streams from modern players or streaming devices will not pass video or allow audio extraction. This unit meets that requirement, enabling both 18 Gbps throughput and lawful decoding of copy-protected material.

Questions about this item

Should I choose the 18Gbps model or a lower-bandwidth extractor for 4K HDR?

The 18Gbps bandwidth supports 4K@60Hz 4:4:4 10-bit HDR pass-through, so choose this model to retain full colour depth and HDR metadata.

What does 18Gbps mean when the extractor is connected to my 4K display?

It allows uncompressed 4K@60Hz 4:4:4 10-bit HDR video to pass through while simultaneously extracting audio to analog stereo or optical S/PDIF outputs.

Does the HDMI 2.0b and HDCP 2.2 interface limit audio formats or cable length?

The interface caps video at 18Gbps and enforces HDCP 2.2 for protected content; audio supports up to 192kHz sampling over optical S/PDIF and analog stereo.
