It says it has 13 amplifiers, but there are 15 speaker terminal pairs.

Hi, I am an owner of the AVC-X8500H coming from Germany.
I have installed an Auro-3D configuration with a 7.1.6 loudspeaker Setup, using Front Heights and Rear Heights on 30° elevation angle, Voice of God (Top surround) and Center Height for the upper level.
For Dolby Atmos a different 7.1.6 setup could be used, also with Front Heights and Rear Heights, which is fully compatible to Auro-3D. But instead of Center Height and Voice of God, which are not known by Dolby Atmos, I’m using Top Middles to have also six loudspeakers in the upper level.
And exactly for this One-for-all setup I have the 15 speaker terminals of the X8500H:
7.1.6 Auro 3D -optimized setup with Front Heights and Rear Heights at 30 degrees elevation,
additional 2 x Top Middle for Dolby Atmos
additional Top Surround (Voice of God) for Auro-3D
additional Center Height für Auro-3D
The Denon AVC-X8500H is using now all available 15 terminals with loudspeakers , and changing the signal output automatically to the right setup, Auro-3D-Layout or Dolby Atmos-Layout. Der Denon switches automatically.
The Denon is not using respectively the pair of the other layout. One pair is not used for each layout, 13 channels are playing all the time.
Auro 3D (extended Auro 3D version of X8500H)
7.1.6 with Front Heights, Rear Heights, Top Surround (VoG) and Center Height
Dolby Atmos:
7.1.6 with Front Heights, Rear Heights and Top Middles
This is possible with the One-for-all-Setup which I described in detail in my Guide (Iink below). So I can use all 15 speakers to cover all Atmos, Auro-3D and DTS:X signals.
