With four 300MHz DSP cores that are capable of processing over one billion computations per second, the AVR-X1800H supports the latest surround sound decoding and processing needs. The AV receiver supports the following stereo & multichannel digital audio formats through its HDMI jacks and optical/coax digital inputs.
Immersive Surround Sound: The Denon AVR-X1800H AV receiver goes beyond regular surround with the latest immersive surround sound formats from Dolby Atmos and DTS:X. The AVR-X1800H offers 7-channels of amplification with support for up to a 7.1 or 5.1.2 channel processing.
- Dolby Atmos: surround sound technology dispenses with channel-based coding in favor of more advanced object-based coding, giving the soundtrack designer the ability to precisely place sounds anywhere in the 3-dimensional space. Now you can enjoy this same award-winning technology at home with the AVR-X1800H that lets you configure a Dolby Atmos speaker system for the ultimate home theater experience.
- Dolby Surround: offers an enhanced cinema experience to your 2ch or multichannel movie soundtracks using your existing 5.1ch, 7.1ch, or Dolby Atmos speaker setup. Dolby Surround enhances audio definition by improving the spatial dimension and overall audio definition of movie soundtracks. It does this by using four distinct surround zones that provide greater control over the exact placement of each detail in a movie sound track, so audio can be matched more accurately to the video on screen; this means more depth and greater realism for your movies. As a result, individual sounds are clearer and more distinct. It also improves the surround sound experience across the entire theater by widening the listening "sweet spot".
- Dolby Atmos Height Virtualization: Dolby Atmos Height Virtualization provides immersive audio without height-channel or overhead speakers, creating virtual height effects in a 5.1ch, 7.1ch or 2.1ch speaker arrangement. Dolby Atmos Height Virtualization applies carefully designed "height-cue" filters to the overhead audio components of your content's soundtrack before they are mixed into your loudspeakers to create the sensation of sound above you.
- DTS:X: The latest immersive surround sound system, features object-based audio coding that lets the soundtrack designer place sonic elements anywhere in the 3D acoustic soundspace, and provides for overhead speakers to deliver a stunning surround sound experience. Along with DTS:X decoding, the AVR-X1800H features DTS-HD Master Audio decoding and other DTS audio technologies.
- DTS Neural:X: DTS Neural:X is an advanced spatial remapping technology from DTS, which provides a fully immersive output for all types of source content; this includes DTS bitstreams and non-encoded (PCM) data. DTS Neural:X delivers a thrilling sense of immersive sound to your speaker layout regardless of the original source format.
- DTS Virtual:X: bridges the gap between DTS:X and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. DTS Virtual:X can be used with any content (from 2ch to 7.1.4ch soundtracks), while delivering virtual height & virtual surround processing based on psychoacoustics (not reflective surfaces).
Audyssey Suite: The AVR-X1800H features the Audyssey suite of powerful DSP features - including MultEQ XT speaker/room calibration, Dynamic Volume, and Dynamic EQ.
- MultEQ XT: Via the supplied measuring microphone, Audyssey MultEQ measures all the speakers in your home theater during setup, including the subwoofer, and then generates multiple high precision DSP room acoustic correction filters, which together provide smoothest and most natural tonal balance, regardless of the brand or model of the various speakers. Up to eight listening positions can be measured, configured, and recorded. MultEQ XT compensates for both time and frequency characteristics of the listening area based on "Audyssey Setup" measurement results. Selection is done from three types of compensation curves - Reference (default and recommended, L/R Bypass, Flat, and Off). You can also choose to manually configure the receiver's speaker setup.
- Dynamic Volume: Audyssey Dynamic Volume features advanced psycho-acoustic processing to deliver clear dialog and wide range sound at reduced volume levels so that you can enjoy theater-level clarity at whatever listening level you choose.
- 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-X1800H 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-X1800H 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-X1800H 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.
Volume & Level Settings: The AVR-X1800H 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. Volume settings can be adjusted independently for the Main Zone and Zone 2.
- 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).
- 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.
eARC (Enhanced Audio Return Channel): This feature of the AV receiver's main HDMI monitor output allows audio to be sent from your compatible TV to the receiver through the same HDMI cable already being used to send audio and video to your TV. This eliminates the need for extra cables connected to your television. eARC (Enhanced Audio Return Channel) will support uncompressed audio formats like Dolby TrueHD, Dolby Atmos, DTS:X, & DTS HD Master Audio - where as the previous ARC (Audio Return Channel) was limited to only Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.
Note: Supported content will be dependent on whether your TV features a HDMI eARC or ARC jack.
Audio Outputs: The Denon AVR-X1800H AV receiver features binding-post speaker terminals, dual sub outputs, and a front-panel headphone jack.

4K/8K HDMI Video Upscaling: The Denon AV receiver offers HDMI video upscaling (up to 4K or 8K Ultra HD) thanks to its NatureVue video processor by Analog Devices. This sophisticated video processor provides upscaling of 1080p high definition HDMI connected sources to 4K or 8K Ultra HD; as well as 4K Video sources to 8K picture quality.
Note: It does not upscale 480i, 480p, 720p, or 1080i video.
Dynamic HDR: 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. Dynamic HDR enables a noticeable progression in overall video image quality from SDR to static HDR, and now static HDR to dynamic HDR. Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast, and wider color gamuts on a scene-by-scene or even a frame-by-frame basis. Dynamic HDR enhanced content is available for movies, videos, TV shows, video and PC games and VR.
- HDR10: HDR10 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.
- HDR10+: is a new open standard that leverages dynamic metadata to produce enhanced contrast and colors on an expanded range of televisions. HDR10+ incorporates dynamic metadata that allows the adjustment of brightness levels on a scene-by-scene or even frame-by-frame basis. By applying individualized tone mapping to each scene, HDR10+ delivers an incredible viewing experience. The picture quality offers an enhanced visual experience with more detailed expressions, brighter shadow areas and more accurate color renderings that stay true to the creator's original intent.
- 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.
Optimized Gaming: Showcased in the AVR-X1800H are new HDMI features like Variable Refresh Rate (VRR), Quick Frame Transport (QFT), and Auto Low Latency Mode (ALLM) - which reduce or eliminate lag and frame tearing to offer a smoother, lag-free gaming experience.
- Variable Refresh Rate (VRR): Support for Variable Refresh Rate (VRR) allows the TV to adapt to certain Game console's frame rate. This helps to reduce or eliminate lag, stutter and frame tearing for more fluid and better detailed gameplay.
- Auto Low Latency Mode (ALLM): The receiver will enter ALLM (Auto Low Latency Mode) when it detects a gaming signal from a compatible device (such as a Xbox One) and allows for a smooth, lag-free gaming experience. During ALLM, the receiver disables the i/p scaler and Auto Lip Sync function.
- Quick Frame Transport (QFT): Quick Frame Transport (QFT) transmits each frame at a higher rate to decrease "display latency", which is the amount of time between a frame being ready for transmission in the GPU and that frame being completely displayed.
