The Blustream HD12DB has been designed to convert and downmix embedded 5.1ch Dolby Audio or DTS Audio within an HDMI signal into a stereo 2ch signal available on HDMI, optical and analog audio outputs.

The HD12DB features an HDMI loop out to pass the original video and multi-channel embedded audio signal to compatible equipment, with a second HDMI output featuring video scaling of resolutions up to 4K 60Hz 4:4:4 video to various lower video formats. This provides the perfect cost-effective solution for ensuring that 4K UHD video and multi-channel audio can be distributed around a multi-room system where there are a mixture of 2ch and 5.1ch zones with multiple output resolution requirements.
