Equal Power Amp Design w Discrete Circuitry: The Denon
AVR-X4000 is equipped with a 7 channel power amplifier rated at 125-watts (into
8-ohms, at 20-20kHz, with 0.08% THD, driving 2 channels) that reproduces
high-fidelity sound in surround mode with equal quality and power for all
channels, true to the original sound. The power amplifier circuit adopts a
discrete-circuit configuration that achieves high-quality surround sound
reproduction. To faithfully reproduce the original surround sound, each of the
Denon AVR-X4000's seven channels are equipped with its own high-current power amp
of equal power. Since these power amps also use discrete circuits configured
with parts strictly selected for their contribution to high sound quality,
rather than with low-cost integrated circuits (ICs), the surround sound playback
is of impeccably high quality.
Amplifier Assignment: The AVR-X4000's seven discrete
amplifier channels can be configured to accommodate your type of home theater
Assigns all power amplifiers within the
receiver for the Main Zone. In this configuration, up to 11 speakers (Front
L/R, Center, Surround L/R, Surround Back L/R, Front Height L/R, Front Wide
L/R) can be connected to the AV receiver. The receiver will automatically
switch between the Surround Back (Dolby TrueHD/DTS-HD), Front Height (Dolby
Pro Logic IIx), and Front Wide (Audyssey DSX) speakers based on the type of
7.1ch content. You must use separate amplifiers for Zone 2 and Zone 3
5.1Ch + Zone 2:
The AVR-X4000's amplifier channels can be
configured as Front L/R, Center, Surround L/R, and Zone 2 for Dolby Digital,
DTS, and Dolby Pro Logic II 5.1ch playback in the main zone and 2ch PCM
playback in the second zone. Surround Back, Front Height, and Front Wide
speakers are not available. Zone 3 speakers must be powered by a separate
5.1Ch + Zone 3:
The receiver's amplifier channels can be
configured as Front L/R, Center, Surround L/R, and Zone 3 for Dolby Digital,
DTS, and Dolby Pro Logic II 5.1ch playback in the main zone and 2ch PCM
playback in the third zone. Surround Back, Front Height, and Front Wide
speakers are not available. Zone 2 speakers must be powered by a separate
5.1Ch + Zone 2/3-Mono:
The AVR-X4000's amplifier channels
can also be configured as Front L/R, Center, Surround L/R, and Zone
2/3 for Dolby Digital, DTS, and Dolby Pro Logic II 5.1ch playback in the main
zone and mono playback in the 2nd and 3rd zone. Surround Back, Front Height,
and Front Wide speakers are not available.
Assigns all amplifiers of the receiver to the Main
Zone with the front speakers bi-amped. Up to five speakers (Front L/R,
Center, & Surround L/R) can be connected to the AV receiver. The Surround
Back amplifier channels of the AV receiver are reassigned to bi-amp the
front speakers. A bi-amplification connection uses two amplifiers for one
speaker. One amplifier is connected to the woofer section of a loudspeaker
while the other is connected to the combined midrange and tweeter section.
With this arrangement each amplifier operates over a limited frequency
range, making its job easier. Surround Back, Front Height, and Front Wide
speakers are not available. Zone 2 and Zone 3 speakers must be powered
by a separate amp.
Assigns all amplifiers within the receiver to
the Main Zone for 7.1ch playback (w/ Surround Back speakers). You can also
connect a second pair of front speakers that are different from the ones
being used during multi-channel playback for playback of 2ch audio. The
receiver will automatically switch the internal power amplifier between your
multi-channel front speakers and your stereo front speakers when listening
to surround sound or 2ch stereo. Front Height/Wide speakers are not
available. A separate amp must be used for Zone 2 and Zone 3.
5.1Ch + Front B:
Assigns five amplifier channels of the receiver
to the Main Zone for up to 5.1ch playback and two amplifier channels to
power another pair of speakers, often called "Speaker B". Surround
Back, Front Height, and Front Wide speakers are not available. A separate
amplifier must be used to power Zone 2 and Zone 3.
Assigns all seven internal amplifiers to the
receiver's main zone and also requires a 2ch external amplifier for 9.1ch
playback. The Front L/R, Center, Surround L/R, Front Height, and Front Wide
L/R speakers are powered by the internal amps. The receiver will
automatically switch between the Front Height (Pro Logic IIz) and Front Wide
(Audyssey DSX) speakers based on soundfield setting. The Surround Back L/R
speakers will need to be powered by an external 2ch amplifier. Zone 2 and
Zone 3 also require separate amps.
24-bit/192kHz DACs + AL24 Processing Plus Technology:
This receiver is equipped with dual 24-bit/192-kHz DACs on all
channels to decode and playback high-resolution recordings with less jitter and
clearer sound. The AVR-X4000also offers AL24 Processing Plus for all channels
(including Front L/R, Center, Surround L/R, and Sub). Denon's proprietary AL24
Processing, an analog waveform reproduction technology, expands the original
16-bit audio data to 24-bits; and can support up to 192kHz sampling frequency.
AL24 Processing Plus thoroughly suppresses quantization noise (the difference
between the actual analog signal and the quantized digital signal) associated
with D/A conversion of LPCM signals to reproduce the low level signals with
optimum clarity that will bring out all the delicate nuances of your movie &
Dynamic Discrete Surround Circuit (D.D.S.C.-HD): The
AVR-X4000 is equipped Denon's Proprietary Dynamic Discrete Surround Circuit-HD,
featuring a dual high-speed 32-bit floating point DSP processors for
high-quality surround audio performance. All elements of the Surround Processor
are optimized to the highest standards by the use of selected high performance
and discrete components, particularly the A/D and D/A converters and the
sophisticated DSP surround decoder.
Hybrid PLL Jitter Reducer: The AVR-X4000 is equipped with a
"Hybrid PLL Jitter Reducer" that is capable of reducing jitter and phase noise
that negatively affect sound quality. The "Hybrid PLL Jitter Reducer" provided
with this unit improves the sound localization, reproducing a natural sound
field that is closer to the original soundtrack.
Denon Link HD Jitter Free Audio: The AVR-X4000 also
incorporates Denon Link HD, Denon's proprietary jitter-free audio transmission
technology, which is designed to work with Denon's DBT-3313CI Universal Blu-ray
sold separately). This feature separates out the timing data from the HDMI
stream, allowing the receiver to re-clock the data with maximum precision,
eliminating distortion-causing jitter for pristine
sound quality. This technology transmits digital sound by transmitting the Denon
A/V receiver's master clock signal to your DBT-3313UDCI and operating the ICs
(integrated circuits) on both sides based on a shared, uniform clock signal. In
digital signal transmissions over conventional HDMI connections, the ICs are
operated with separate clock signals, resulting in considerable jitter and loss
of resolution in the sound. Denon Link HD works not only with Blu-ray disc, but
with all HDMI digital output signals; including DVD, DVD-Audio, Super Audio CD,
music CD, and music streamed from a network.
Multi-Channel Decoding Formats: The Denon AVR-X4000 AV
receiver supports the following multi-channel (Dolby Digital, DTS, Dolby Pro
Logic) decoding formats.
- Dolby Digital:
Dolby, Digital EX,
Dolby Digital Plus,
DTS-HD Master Audio,
DTS-HD High Resolution,
DTS Neo: 6,

Note: Dolby Digital and DTS listening modes can only be
selected if your audio source is connected to the AV receiver via a digital
audio connection (HDMI, optical, or coaxial). To enjoy true 7.1ch Dolby
Digital TrueHD and DTS-HD surround sound, the receiver must be connected to
your Blu-ray player via HDMI.
Denon Original Listening Modes: Denon's Original Listening
Modes, combined with Dolby Digital/DTS/Dolby Pro Logic 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. You can choose from the
- Rock Arena: For rock and popular music sources, this
mode surrounds you with reflected sound of the kind you would hear at a live
- Jazz Club: This mode recreates the atmosphere of a live
house where the ceiling is low and you are enveloped with rich doses of
- Matrix: With this mode, you can add rich reflected
sound to 2-channel stereo music sources where reflected sound is normally
- Video Game: This mode is suited for achieving surround
sound with video games..
- Mono Movie: This mode is used when you listen to
recorded monaural sound sources such as AM radio broadcasts or news programs
from the center speaker.
- Virtual: Enjoy surround effects using only the front
speakers or set of headphones.
- Multichannel Stereo: Left and right stereo channels are
distributed to all the speakers so that stereo sound can be heard from all
directions at any listening position.
Note: This unit automatically generates a list of all
the playable sound modes based on the input audio format and the current
speaker setup configuration and displays the list on the screen. Therefore,
you can select a correct surround playback mode even if you are not familiar
with sound mode selection.
Direct Listening Modes: The Denon AVR-X4000 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 noised
being added to the audio signal.
Audyssey Technology: The AVR-X4000 features a full package
of Audyssey audio technologies for optimal sound quality. Audyssey Dynamic
Volume offers real-time volume adjustment, while Audyssey DynamicEQ improves
your system's surround effects during low volume levels. Audyssey MultEQ XT32
automatically sets speakers and subs to suit your room's listening environment
and the speakers' characteristics. The AVR-X4--- also features two Audyssey
technologies (Sub EQ HT & LFC) designed to optimize bass performance. The AV
receiver even offers Audyssey DSX which adds front speaker effects.
- Audyssey MultEQ XT32: Audyssey MultEQ XT32 technology
helps create an optimal acoustic profile for your home theater. Using the
included setup microphone, Audyssey MultEQ XT32 measures sound levels and
adjusts speaker configuration accordingly, making setup fast and easy. This
room acoustic measuring and correction system analyzes (via the included
microphone) the audio characteristics of your speaker system and your
listening environment at up to 8 measurement points and automatically
tailors the sound for top audio fidelity. You can set the Audyssey MultEQ XT
to one of the following modes.
- Audyssey: Optimizes the crossover point, output
level, delay time, and equalization of all speakers based on speaker
frequency response, speaker location, and room acoustics.
- Audyssey Bypass L/R: Optimizes all speakers except
front left and right.
- Audyssey Flat: Optimizes frequency response of all
speakers to flat.
- Manual: Adjusts the tonal quality for each speaker
individually using the manual equalizer settings (63 Hz, 125 Hz, 250 Hz,
500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, and 16 kHz); from -20 to +6 dB .
- Off: Turns equalizer off.
- Audyssey Sub EQ HT: Audyssey Sub EQ HT provides
individual tailoring for each subwoofer in a dual subwoofer setup,
delivering the optimum combination of highest deep bass output and lowest
- Audyssey LFC: Audyssey LFC processing analyses and
processes bass content on a continuous basis and custom tailors the sound
via advanced psychoacoustic algorithms to deliver dynamic bass response
within the listening room without annoying family members or neighbors in
- Dynamic EQ: Audio engineers mix music and movie
soundtracks at reference levels much louder than typical home listening
levels. At lower volumes the human ear perceives sound differently; voices
change, bass dissipates, and the surround effect becomes less enveloping.
Dynamic EQ adjusts the frequency response curve based on volume to maintain
consistent bass output, octave-to-octave balance, and surround impact,
resulting in rich sound at any volume. You can set the Dynamic EQ to 0, 5,
10, or 15 dB.
- Audyssey Dynamic Volume: Audyssey Dynamic Volume solves
the problem of large variations in volume level between television programs,
commercials, and between the soft and loud passages of movies. Dynamic
Volume addresses the issue of commercials that are too loud and movie
soundtracks with vast differences between soft and loud passages; the
results are more intelligible dialogue, loud passages maintain impact, and
soft whispers are heard clearly. When the volume level changes, Dynamic EQ
also adjusts the frequency response to maintain sound quality. You can set
the Dynamic Volume to Day (low), Evening (middle), Midnight (high), or off.
- Audyssey Dynamic Surround Expansion (DSX): Audyssey DSX
adds front effect speakers to improve spatial sound reproduction. Starting
with a 5.1 channel system, DSX adds front Wide and/or front Height channels
for better sound staging (although both wide and height speakers can be
added, only one pair is used at a time). DSX also applies Surround
Envelopment Processing to enhance the blend between the front and surround
Surround Parameters: You can adjust the following surround
- Dolby Pro Logic II Music Settings: While listening in
the Dolby Pro Logic II Music format, there are three further enhancements
you can adjust:
- Panorama: Broadens the front stereo image to the

of your desired acoustic environment when using specific Denon Original
Surround Modes; select Small, Medium small, Medium, Medium large, or
- Effect Level: This function adjusts the effect
signal level from 1 to 15 when using specific Denon Original Surround
- Delay Time: This feature adjusts the delay time
(0-300ms) to control the sound stage size.
- Height Gain: Adjust the volume (Low/Mid/High) of the
Front Height channels in Dolby Pro Logic IIz.
- Audyssey DSX Settings: While listening in the Audyssey
DSX audio format, there are two further enhancements you can adjust:
- Stage Height: adjust sound stage height (+/-10) when using
front height speakers
- Stage Width: adjust sound stage width (+/-10) when
using front wide speakers
- Center Gain: During DTS NEO:X, this function distributes the
dialog output from the center channel to the front left and right channels
and widens the sound image in t he front.
Audio Enhancements: The Denon AVR-X4000 receiver provides
various audio enhancements to deliver a high-quality listening experience every
- 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, Dolby Pro Logic (including PL II, PL IIx, PL IIz),
and DTS Neo:6 modes.
- 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.
- Tone Settings: You can independently adjust the
system's overall Bass and Treble settings from -6 to +6 dB.
Volume Settings: The AVR-X4000 offers the following volume
- Volume Scale: You can choose to display an Absolute

important to own a receiver that recognizes 3D video signals. The AVR-X4000
is able to pass through 3D signals from your Blu-ray player, ensuring that
the 3D effect doesn't get lost in translation. It also recognizes signals
from 3D television broadcasts. By connecting a 3D-compliant Blu-ray disc
player and 3D-compliant TV to the AVR-X4000, you will have a 3D home theater
where you can enjoy high-definition sound and video on a level you've never
- Deep/x.v.Color Support: The AVR-X4000 also supports Deep
Color and x.v.Color content, which can display a larger color range than
standard-definition schemes. The result is a more lifelike, vibrant picture.
- LipSync: If needed, the audio signal can be manually
delayed to match the video signal; adjust from 0-200ms.
- ARC (Audio Return Channel): This feature allows audio to be
sent from your compatible HDTV to your 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.
Note: The AV receiver's HDMI 2.0 jacks do not support the
latest HDCP 2.2 copyright protection for 4K ultra-HD content, so it will not
support 4K content from satellite/cable providers, online video services,
