  • Extract 5.1-channel surround via optical to soundbar

  • Pass 4K@60 Hz HDR video with HDCP 2.2 compliance

What It Is

The Tendak HDMI Audio Extractor is a 2-in-1 accessory that takes an HDMI 2.0 signal, passes the video through to a 4K display, and splits the audio to optical S/PDIF, 3.5 mm stereo and RCA L/R outputs. A built-in volume knob controls the analog output level.

Who It Suits

Ideal for users with a source device that lacks an optical audio port or cannot send audio over HDMI, and who need to feed a soundbar, surround receiver, headphones or powered speakers. Buyers who require HDMI 2.1 bandwidth for higher refresh rates, or who need to extract audio from eARC sources, should look at a different solution.

Key Specification

Supports HDMI 2.0 video up to 4K at 60 Hz with RGB 4:4:4 and YUV 4:4:4 chroma, HDCP 2.2 and 1.4, HDR10, and 5.1-channel audio on optical plus 2.0-channel analog on 3.5 mm and RCA.

Highlights

  • Extract 5.1-channel surround via optical to soundbar
  • Connect headphones or speakers through 3.5 mm stereo jack
  • Output analogue stereo to amplifier via RCA L/R
  • Adjust analogue volume directly with built-in knob
  • Pass 4K@60 Hz HDR video with HDCP 2.2 compliance

Questions about this item

What HDMI source and display do I need to use the Tendak extractor at 4K@60Hz?

Connect any HDMI 2.0 source such as a console or media player to the input, then run an HDMI 2.0 cable from the extractor output to a 4K@60Hz-capable display.

Will the extractor pass 1080p@60Hz and 720p signals from older devices without downscaling?

Yes, the unit is backward compatible with 1080p 3D@60Hz, 1080i and 720p, so legacy sources pass through at their native resolution.

How can I confirm the extractor is outputting 5.1-channel audio over optical after setup?

Play a test file encoded in AC-3, DTS or LPCM 7.1; your soundbar or AV receiver should indicate a 5.1-channel bitstream on its display.
