This LogiLink HDMI extractor allows you to split audio and video signals up to 4K/60 Hz. So you are no longer bound to the speakers of your TV, but can easily integrate your surround system. Projectors without speakers can also still be used and you save unnecessary costs for retrofitting. The HDMI signal is passed on in parallel to a display (e.g. monitors, TVs or beamers) with support for HDCP 2.2, HDR, CEC as well as 3D. The audio transmission in DTS, Dolby Digital, DTS-HD Master Audio and Dolby TrueHD as well as the connection of an external AV receiver (ARC), also leaves nothing to be desired.
