This extractor allows you to split audio and video from an HDMI cable into separate signals so that you can get the sound directly to speakers or headphones while the image signal continues in a second HDMI cable from the extractor to the TV or monitor. The extractor is easy to use and supports 3D, 1080p and 4K completely without loss of quality making it a flexible multimedia accessory. With a button on the extractor, you can switch between the audio channels 2.1, 5.1 or Pass which allows the sound to go through without modification. The extractor also supports the Audio Return Channel (ARC) which allows audio signals in the HDMI cable to travel both ways.- Shatter audio and video signals from HDMI without loss of quality- 3D, 1080p, and 4K- Get audio signals to SPDIF, 3.5mm Aux (L or R) or via ARC- Choose from audio channels 2.1, 5.1 or Unchanged Sound Pass- Audio Sync >>lt br>Output : 1x HDMI - 1x SPDIF - 1x 3.5mm AuxAudio format: DTS-HD or Dolby true HD or LPCM7.1 or DTS or Dolby-AC371s or DSDBlu-ray support: 24 or 50 or 60fs or HD dvd or XVYCCHDMI Resolution: 4k or 2k or 3D or 1080p or 1080 or 720p or 576p or 576 or 480p or 480iMax Bandwidth: 520 MHzMax Band Speed: 18 GbpsPower Supply: DC 5V or 1AInput or Output TMDS Signal: 0.5 - 1.5 Volt p-p (TTL)Input or Output DDC Signal: 5 Volt p-p (TTL)Width: 6.8 cmHeight : 2.3 cmDepth: 5.7 cmWeight: 74 gMaterial: AluminiumColor: BlackPackaging Contains:1x HDMI Audio Extractorandlt br> 1x 3.5mm Aux to L or R Adapter Cable (32 cm)1x Power Cable with DC 5V or 1A Adapter (80 cm)1x ManualOBSThis device may be having problems with Chromecast.
