VigilLink VLHA-DWM 4K HDMI Audio Extractor with Downmix

The VLHA-DWM extracts audio from an HDMI source to a digital optical output and an analog stereo pair, passing 4K2K@50/60Hz (YUV 4:4:4) video through untouched. What sets it apart from the plain extractor is downmix: multichannel bitstream audio is folded to two channels for the analog output rather than going silent.

Optical and HDMI outputs keep their original pass-through audio at the same time, including LPCM 2CH, Dolby TrueHD, Dolby Digital Plus, Dolby Atmos, and DTS-HD Master Audio at up to 192kHz. The unit is HDMI 2.0b and HDCP 2.2 compliant at 18Gbps with 10-bit HDR pass-through and CEC bypass.
