Add an extra stereo power amp and the Denon lets you configure four ceiling or Atmos-enabled speakers as well as full 7-channel surround sound. Alternatively, use two Atmos speakers and enjoy a broad soundstage with 'front wide speakers' forming a 9.2.2 system. If you don't fancy a Dolby Atmos specific system but want the most immersive sound possible, go for an 11.2 configuration. This offers 7.2 sound with the addition of front width and front height speakers.
With no fewer than nine powered channels, the Denon AVC-X3800H gives you a wide choice of speaker configurations. Choose between 7.4.2 or 5.4.4 Dolby Atmos speaker configurations with two or four ceiling speakers. Alternatively, stick with 5.4.2 and power a second pair of speakers in another room or bi-amp your main pair of speakers. As your system grows, so the capability of this Denon AVC grows with it.
