The Denon avr-x4500h is the first of its kind to be IMAX enhanced-ready. It also has high dynamic range video support. That means it will play HDR content from compatible sources, and it will display a higher level of detail in highlights and darker areas than standard dynamic range (SDR) video.
It supports Dolby Atmos which is an immersive audio format that uses up to 128 independent sound objects that are free of channel limitations allowing sound to flow around the audience and move overhead. It is capable of creating a virtual surround environment that combines a base horizontal layer with a height layer and a top overhead channel which can be decoded from standard 5.1 PCM carrier signals.
All channels feature premium 32-bit AKM AK4458 VN digital-to-analog converters with AL32 processing for high resolution audio. It can handle lossless files up to 24 bit/192kHz and can decode up to 5.6MHz DSD.
Enhanced HDMI ARC supports uncompressed audio formats such as Dolby Atmos, DTS:X, DTS HD Master Audio and Dolby TrueHD. It can be connected to a compatible TV via an ARC-enabled HDMI cable to transmit both audio and video, and can be controlled from the receiver. Other features include Audyssey Dynamic EQ, Dynamic Volume, LFC and Sub EQ HT. It can also be used in a multi-room system with up to 3 additional zones. Component video outputs are included for Zone 2 connections and Zone 3 preamp inputs allow for power amplification of dedicated zone speakers.
