HDMI Audio Extractor with ARC

The LUOM OZV8-2 takes a single HDMI source and delivers one HDMI ARC output plus optical Toslink SPDIF, stereo RCA and a 3.5 mm headphone jack. It is built for users who need to separate audio from a 4K video stream for an external sound system or headphones. The compact black unit includes a 5 V power adapter and requires no software setup.

4K 60 Hz YUV 4:4:4 bandwidth

The splitter handles 4K at 60 Hz with YUV 4:4:4 chroma subsampling and a maximum bandwidth of 600 MHz or 18.5 Gbps. It supports HDCP 2.2, HDR10, Dolby Vision and deep colour up to 36 bit, so the video quality remains intact while audio is extracted. Input and output cables up to 10 m AWG26 are supported.

Sustained signal retiming and format support

Signal retiming keeps the HDMI link stable during long playback sessions, preventing dropouts that can appear after the initial handshake. The extractor passes multi-channel formats including LPCM 7.1, DTS-HD, Dolby TrueHD, DTS, Dolby AC3 and DSD without decoding them. It is not for installations that require multiple HDMI outputs or switching between several sources.

What does 4K@60Hz actually deliver when the extractor is connected to my display?

It passes 4K at 60 frames per second with YUV4:4:4 chroma, HDR10, Dolby Vision and deep colour up to 36-bit, so the TV receives the full 18.5 Gbps signal while audio is split off.

How does the HDMI 2.0b interface limit the audio formats I can extract?

The 600 MHz bandwidth and HDCP 2.2 support allow extraction of DTS-HD, Dolby TrueHD, LPCM 7.1, DTS, Dolby AC3 and DSD through the optical, RCA and 3.5 mm ports.

What space and cabling do I need to fit the extractor in my rack?

The unit measures 84.5 x 61.8 x 21 mm and weighs 4.4 ounces; it requires a 5 V/1 A power adapter and works with HDMI cables up to 10 m AWG26 on both input and output.
