Forever downmixing has been limited to 5.1 Audio. No downmixer was able to down mix more than 6 channels, and definitly couldn't handle Dolby Atmos or DTS-HD.
That era is over and a new one has started with the AC-AVDM-AUHD downmixer from AVPro Edge. This is the first device in the world that is capable of downmixing beyond 6 channels.
Stop limiting your audio to 5.1, get Dolby Atmos in your theater room and two channel stereo throughout the rest of your home.
