Sony STR-DN1080 Manual page 84

Depending on the audio format, if you select [Direct] and play a 5.1ch source when surround
speakers and two surround back speakers are connected, the same audio as that from surround
speakers will be output from surround back speakers, similar to that of a 7.1ch surround system. The
sound level of surround and surround back speakers are adjusted automatically for optimum
balance.
Dolby Atmos is decoded as Dolby TrueHD or Dolby Digital Plus when a sound field other than [Multi
Ch Stereo], [A.F.D.] or [Dolby Surround] is selected.
If an input other than [USB], [Bluetooth], [Home Network], or [Music Service List] (when music is
being played back using Spotify Connect) has been selected, [Audio Enhancer] cannot be selected
when you press MUSIC.
