With the Denon AVR-X4500H, you have a 11.2-channel receiver at your disposal. The receiver supports Dolby Atmos. If you have speakers that support this, the sound comes from all sides. This technology lets the sound of your surround set reflect to your listening position via the ceiling. This way, you get to enjoy spatial audio. The receiver plays Hi-Res audio files, which means you can listen to music in high quality. Do you have HEOS multi-room speakers? Integrate the receiver with the speakers to stream music throughout your home.
