The document you want is the HDMI Specifications Guide .. which curiously is missing from the 689 page, but is linked from the 589 page: http://www.usa.denon.com/AVR_3_Digit..._x89_v0708.pdf
The 589 and 689 do not decode any HDMI audio, only repeat it on HDMI-out.
Denon excels at excluding features you'd never think to check to see if missing. Be amazing to see how product marketing managed to convince engineering this was an acceptable feature compromise.
