360 Spatial Sound Mapping is a separate feature which is designed to enhance immersive sound formats such as Dolby Atmos, DTS:X and 360 Reality Audio to be even more immersive and enveloping. Theoretically, you can enhance these 360 Reality Audio tracks, as well as content in Dolby Digital, DTS, DTS:X or Dolby Atmos by engaging the receiver’s “360 Spatial Sound Mapping” feature. For most listening, I kept the receiver in its “AFD” (Auto Format Decoding) mode which detected the incoming sound format, be that 2-channel or 360 Reality Audio or Dolby Atmos, and presented that format using the necessary speakers with minimal additional processing.
