• Dynamic EQ: Audyssey Dynamic EQ also features advanced DSP processing to deliver full range wide-band response, even at reduced volume levels. Dynamic EQ Reference Level Offset provides three offsets from the film level reference (5 dB, 10 dB, and 15 dB) that can be selected when the mix level of the content is not within the standard.

Listening Modes: The Denon AVR-X4500H features a variety of Listening modes to choose from, so you can enjoy your movie or music soundtrack the way you want to hear it.

• Auto Detection: In Auto Mode, the Listening Mode switches automatically to the corresponding type of audio input signal (Dolby Digital, Dolby TrueHD, Dolby Digital Plus, DTS, DTS-HD, or multichannel PCM) that is detected. If the input signal is analog or PCM (2-channel), stereo playback is used.
• Denon Original Sound: Denon's Original Listening Modes, combined with Dolby Digital/DTS processing, produce more realistic, powerful sound effects for your movie and music sound tracks based on the type of content and your home theater setup. Choose between Rock Arena, Jazz Club, Matrix, Video Game, Mono Movie, Multichannel Stereo, or Virtual (surround from only front speakers or headphones).
• Stereo Playback: Sound is output from the front left and right speakers, as well as the powered subwoofer. If multichannel signals are input, they are mixed down to 2-channel audio. The tone settings can be adjusted.
• Direct Modes: The Denon AVR-X4500H offers two Direct Listening Modes which bypass the receiver's tone & DSP processing for higher sound quality performance. Direct Mode provides playback of 2ch or Multichannel audio in its original form, without any surround or tone processing. Pure Direct Mode goes a step further by turning off the receiver's display and analog video circuitry to minimize the possibility of any noise being added to the audio signal.

Audio Enhancements: The Denon AVR-X4500H receiver provides various audio enhancements to deliver a high-quality listening experience every time.

• CINEMA EQ (Cinema Equalizer): The Cinema EQ function gently decreases the level of the extreme high frequencies, compensating for overly-bright sounding motion picture soundtracks. Select this function if the sound from the front speakers is too bright. This function only works in the Dolby Digital & DTS modes.
• Compressed Audio Restorer: Compressed audio formats such as MP3, WMA (Windows Media Audio), and MPEG-4 AAC reduce the amount of data by eliminating signal components that are hard for the human ear to hear. The Restorer function generates the signals eliminated upon compression, restoring the sound to conditions near those of the original sound before compression. It also corrects the sense of volume of the bass to obtain richer sound with compressed audio signals.
• Dynamic Range Compression (DRC): Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loud sounds). For listening late at night, or whenever the maximum sound level is lower than usual, Compressing the dynamic range allows you to hear all of the sounds in the soundtrack with reduced dynamic range. DRC works when playing program sources recorded in Dolby Digital or DTS.
• Room Size: The receiver's audio output can be set to simulate the acoustics of a Small, Medium Small, Medium (default), Medium Large, or Large room environment. This setting is not an indication of the actual size of your listening area.
• Center Spread & Dialog Control: Center Spread expands the center channel signal to left and right front speakers to create a wider frontal audio image for the listener, when in Dolby Surround mode. Dialog Control adjusts the volume of dialog in movies and vocals in music so they can be heard more easily, when in DTS:X mode.
• LFE + Main: The LFE + Main setting boosts the bass sound by feeding the low-frequency signal to both the loudspeakers and the powered subwoofer, regardless of audio format or listening mode.

ARC + eARC (via available Firmware Update): ARC (Audio Return Channel) allows the receiver's HDMI monitor output allows audio to be sent from your compatible HDTV to the receiver through the same HDMI cable already being used to send audio and video to your HDTV. This eliminates the need for extra cables connected to your television. The receiver will also support eARC (Enhanced Audio Return Channel) via an available firmware update. eARC will support uncomprerssed audio formats like Dolby TrueHD, Dolby Atmos, DTS:X, & DTS HD Master Audio - where standard ARC was limited to Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.

Volume & Level Settings: The AVR-X4500H offers the following volume & level settings.

• Volume Settings: You can choose to display an Absolute volume scale (0-98) or Relative volume scale (-79.5 to 18dB). You can also set a maximum volume level of 0 (80), -10 (70), or -20 (60) dB to limit the receiver's total volume output. In addition, you can define the volume setting that is active when the power is turned on; select "Mute", -79 to +18dB (1-98), or Last. These settings can be set independently for the Main Zone, Zone 2, and Zone 3.
• Mute Level: You can set the amount of attenuation for the audio muting circuit; -40dB or -20dB below current volume, or full mute (sound turned off entirely). The Mute Level can be set independently for the Main Zone, Zone 2, and Zone 2.
• Channel, Center, & Subwoofer Level: The volume level (-12 to +12dB) of each channel can be changed while listening to audio for each input source. You can also adjust the center channel volume level (-12 to +12dB) independently from the channel level to clarify the dialog for all sources. In addition, you can adjust the subwoofer channel volume level (-12 to +12dB) independently from the channel level to emphasize low frequencies for all input sources.
• Source Level: This function adjusts the playback level of the currently selected input source's audio input. Use this feature if there are differences in the input volume levels between different sources. You can correct the playback level of the audio input from -12 to +12dB.

Audio Outputs: The Denon AV receiver features color-coded binding-post speaker terminals, 11.2ch pre-outs, and a front-panel headphone jack.

• Color-Coded Speaker Terminals: The receiver has binding-post terminals for all speaker connections. The binding-post terminals can accept bare wire, pin connectors, and banana plugs (single/dual). The receiver will accept speaker impedances of 4 to 16-ohm. The AV receiver comes with color-coded labels to easily identify which channel a speaker cable should be connected to. Since the speaker cables have labels in the same colors as the connectors on the AVR-X4500H's rear panel, there's no longer any confusion about which terminals they should be connected to.
• 11.2Ch Pre-Outs: The AV receiver features 11.2ch pre-amp outputs (Front L/R, Center, Surround L/R, Surround Back L/R, Height 1 L/R, Height 2 L/R, and Dual Subs) for connection to external power amplifiers. The pre-outs are variable. For compatibility with dual subwoofer home theater systems, the AVR-X4500H features two discrete subwoofer outputs. With dual subwoofers, which can be placed in different parts of the room, you'll benefit from response averaging, which helps provide smoother and more detailed deep bass, compared to a conventional single subwoofer speaker system.
• Headphone Jack: When headphones are plugged into the full-size 1/4" jack on the front panel, all the speakers are automatically muted.

Phono Input: The Denon AVR-X4500H is outfitted with a Phono input (MM), so you can connect your turntable and listen to your vinyl records with high-quality sound.

The AVR-X4500H also features HDCP 2.2 compatibility, a requirement for 4K Ultra HD copy-protected content.

• 4K/60Hz + HDCP 2.2: The AVR-X4500H's HDMI inputs and monitor outputs support up to 4K (3840x2160 pixels) video @ 60 frames per second. All of the HDMI jacks support HDCP 2.2, which fully complies with the latest copyright protection standard for 4K video transmission. The receiver will also pass a 480i, 480p, 720p, 1080i, or 1080p video signals via HDMI.
• 4:4:4 Color Subsampling: The HDMI inputs and monitor outputs support RGB, YCbCr 4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 color subsampling (@ 60Hz or 50Hz). With 4:4:4 color subsampling, luminance (brightness) and chroma (color) are sampled at the same rate; resulting in an RGB color palette as big as the video sampling rate for a video image with more colors, plus greater color accuracy and detail. The front-panel HDMI only supports 4K 60/50Hz using format YCbCr 4:2:0 only.
• Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a much wider color gamut and represents about 75% of the total visual color spectrum, while the current Rec. 709 color standard selected as the color space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the total visual color spectrum.
• 21:9 Aspect Ratio: By supporting 21:9 aspect ratio, this receiver can show films recorded in the Cinema Scope format on your TV for a much more immersive video experience. When these types of films are viewed in the usual 16:9 ratio, you see black bars at the top and bottom of the screen; 21:9 eliminates these bars.

HDR (High Dynamic Range): The Denon AVR-X4500H supports HDR (high dynamic range) Video - including HDR 10, Dolby Vision, and Hybrid Log-Gamma. HDR provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. HDR reproduces a greater dynamic range of luminosity or brightness levels, creating greater contrast. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth.

• HDR 10: HDR 10 is an open standard and currently the most popular HDR format on the market. It uses static metadata at the start of a movie to tell the receiver and your TV that the video content is encoded using HDR.
• Hybrid-Log Gamma: HLG (Hybrid-Log Gamma) is primarily designed for live video feed and over-the-air broadcasts. It uses no pre-encoded metadata and is backwards compatible with SDR. HLG's native compatibility allows much of today's existing SDR infrastructure to be re-used for HDR in the future.
• Dolby Vision: Unlike HDR 10 which contains static metadata and HLG which uses no metadata, Dolby Vision uses dynamic metadata technology which sets individual color and brightness levels for each and every scene. Dolby works directly with filmmakers at major Hollywood studios to create superior HDR video masters of blockbuster movies.

4K Video Upconversion & Upscaling: The Denon AV receiver's sophisticated video processor provides upconversion from standard definition (480i/480p) and high definition (720p/1080i/1080p) sources to 4K Ultra HD (3840x2160 pixels), which lets you connect all your analog (composite/component) or digital (HDMI) video sources to the AVR-X4500H and then connect to your TV with just a single HDMI cable. Only the receiver's main HDMI output supports video upconversion.

Three HDMI Outputs: The two parallel HDMI outputs distribute the same HDMI input signal simultaneously to two separate displays, while the discrete HDMI output allows you to play a different HDMI audio/video source in another zone (Zone 2).

HDMI Standby Pass-Through: When the AV receiver is in "Standby" mode and the HDMI Standby Pass-Through function is enabled, both audio/video streams from the receivers HDMI input will be output to your television, via the AV receiver's HDMI monitor output. Once the receiver is turned "On", only video will pass through the monitor output to your TV and the audio is directed to the receiver's speaker outputs.

• HDMI Input: Selects the HDMI Input for which the HDMI Standby Pass-Through function is enabled.
• Last: The HDMI Standby-Through function is activated on the input source selected at the time of setting the AV receiver to the "Standby" mode.
• Off: The HDMI Standby Pass-Through function is disabled.
