HDMI 2CH/5.1CH 4Kx2K compatible. I purchased this on Amazon for around 2000 yen and have been using it. I am selling it because I no longer have a use for it. I will include a power cable (approximately 75cm long). Please note that an AC adapter is not included. Analog output is available via the headphone jack (3.5mm) for stereo 2ch. - Brand: Amazon Basics - Model: HDMI 2CH/5.1CH Audio Extractor - Supported Resolution: 4Kx2K - Input Ports: HDMI in - Output Ports: HDMI out, SPDIF - Power: DC 5V Thank you for looking.
