Network & Tuner Functions
High-Current, Low Impedance Design: The Denon AVR-4520CI is
built to last and delivers audiophile-type sound thanks to its 150-watt per
channel power amplifier with symmetrical monolithic construction, Denon's
custom-made high current power transistors (D.H.C.T) for high current
capability, Denon custom-made massive capacitors and Selected Schottky Barrier
Diodes for high bursts of power, and a vibration resistant chassis that
suppresses the negative influence of vibration on sound quality.
Equal Power Amp Design w/ Discrete Circuitry: The Denon AVR-4520CI
is equipped with a 9 channel power amplifier rated at 150-watts (into 8-ohms, at
20-20kHz, with 0.05% 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-4520CI's five 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-4520CI supports up to 9.2
channels (Front L/R, Center, Surround L/R, Surround Back L/R, Front Wide/Height and Dual SW) for
surround playback defined by the Blu-ray disc format. The nine amplifier
channels built into the receiver are typically used for 9.2 channel surround in
the main room, but there are various amplifier configurations to accommodate
your home theater setup:
- 9.2ch (SB/FH/FW): Assigns all power amplifiers within
the receiver for the Main Zone. Up to 9.2ch playback is possible.
- 7.2ch + Zone 2: Assigns seven amplifier channels of the
receiver to the Main Zone and the other two channels to Zone 2. The Main
Zone will be limited to 7.2ch playback, while 2ch audio can be sent to Zone
- 5.2ch + Zone 2/3:
Assigns five amplifier channels of the receiver to the Main Zone, and two
channels (each) to Zone 2 and Zone 3. The Main Zone is limited to 5.2ch
playback, while 2ch audio can be sent to Zone 2 and Zone 3.
- 7.2ch + Zone 2/3-Mono:
Assigns seven amplifier channels of the
receiver to the Main Zone, and two shared channels to Zone 2 and Zone 3. The
Main Zone is limited to 7.2ch playback, while Zone 2 and Zone 3 produce a
mono audio signal.
- 7.2ch (Bi-Amp):
Assigns all amplifiers of the receiver to the Main Zone with the front
speakers bi-amped. Up to 7.2ch playback is possible.
- 5.2ch (Bi-Amp) + Zone 2:
Assigns seven amplifier channels of the
receiver to the Main Zone with the front speakers bi-amped, for up to 7.2ch
playback. The other two amplifier channels are assigned to Zone 2 for stereo
audio in a second room.
- 9.2ch/2ch Front:
Assigns all amplifiers within the receiver to the Main Zone for 9.2ch
playback. 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.
- 7.2ch/2ch Front (Bi-Amp):
Assigns all amplifiers within the receiver to the Main Zone, with the front
speakers bi-amped, for up to 7.2ch playback. 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.
- 7.2ch + Front B: Assigns seven amplifier channels of
the receiver to the Main Zone for up to 7.2ch playback. The two other
channels are used to power another pair of speakers, often called "Speaker
- Discrete 11.2ch:
Assigns all amplifiers within the receiver to the Main Zone and allows you
to connect Front Height speakers to the receiver's preamp-outputs using an
external amplifier, for up to 11.2ch playback.
- Pre-Amplifier: Allows
you to connect all your speakers using an external power amplifier and uses
this unit as a preamplifier. Amplifier section is turned off.
- Custom: Lets you assign the amplifier channels within
the receiver as you prefer for speaker connection (Front, Center, Surround,
Surround Back, Front Height, Front Wide, Zone 2, Zone 3, None).
Note: In 7.2ch and 9.2ch modes, you can choose which
surround/front speakers are used - Surround Back/Front Height, Surround
Back/Front Wide, or Front Height/Front Wide.
The receiver will then automatically switch between the surround/front speakers
in accordance with the surround mode.
32-bit/196kHz DAC + AL32 Processing:
The AVR-4520CI employs 32-bit/192 kHz Burr Brown DACs and Denon's AL32
Processing Multichannel Technology for highest resolution audio playback. This
receiver is equipped with 32-bit/192-kHz Burr-Brown DACs on all channels to decode and playback
high-resolution recordings with less jitter and clearer sound. The
AVR-4520CI also incorporates AL32 Processing for all its channels. Denon's proprietary AL32 Processing expands the original 16-bit audio data to
32-bits; and can support up to 192kHz sampling frequency. AL32 Processing
thoroughly suppresses quantization noise (the difference between the actual
analog signal and the quantized digital signal) associated with D/A conversion
of LPCM signals in order to reproduce multichannel audio signals with optimum clarity that
will bring out all the delicate nuances of your movie & music soundtracks.
Dynamic Discrete Surround Circuit (D.D.S.C.-HD32):
The AVR-4520's incredible surround sound performance is made possible by Denon's
exclusive Dynamic Discrete Surround Circuit (D.D.S.C.-HD32) technology, which
dispenses with conventional all-in-one chips in favor of a trio of high-quality
32bit DSP processors.
Hybrid PLL Jitter Reducer: The AVR-4520CI 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-4520CI 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 Player (033DBT3313,
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.
Audyssey Technology: The AVR-4520CI 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-4520 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 distortion.
- 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
Multi-Channel Decoding Formats: The Denon AVR4520CI AV
receiver supports the following multi-channel (Dolby Digital, DTS, Dolby Pro
Logic) decoding formats.
- Dolby Digital:

Direct Listening Modes: The Denon AVR-4502CI 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.
Tone Settings: You can independently adjust the system's
overall Bass and Treble settings from -6 to +6 dB.
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
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. You can choose from 4 settings:
- Mode 1 (Restorer 64): Optimized mode for compressed
sources with very weak highs.
- Mode 2 (Restorer 96): Apply suitable bass & treble
boost for all compressed sources.
- Mode 3 (Restored HQ): Optimized mode for compressed
sources with normal highs.
- Off: Does not use Restored function.
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.
Night Mode: The Night Mode optimizes sound for late night listening.
This function can be set to Low, Mid, High, or Off.
Dialogue Enhancer: This feature adjusts and enhances the frequency
band corresponding to the human voice at the center channel speaker to make
voices and dialogue clearer. It can be set to Low, Medium, High, or Off.
Bass Sync: For multichannel content (such as Blu-ray discs), the
recorded low frequency effects (LFE) may be out of synch and delayed. This
function corrects (0-16ms) such a delay of low frequency effects (LFE).
Volume Settings: The AVR-4520CI offers the following volume
- Volume Scale: You can choose to display
an Absolute volume scale (0-98) or Relative volume scale (-79.5

Satellite/Cable box) to your TV. It
also allows you to connect all of your devices to your TV with a single HDMI
cable (via its three 3 HDMI outputs; two parallel and one discrete), reducing cable clutter. The two
parallel HDMI outputs distribute the same video signal simultaneously to two
separate displays. The discrete HDMI output allows you to play a different
audio/video source in another zone. The HDMI
inputs are assignable to different input sources. They support HDCP copyright
protection and are compatible with 3D signals, ARC, Deep Color, xvYCC
technology, Auto LipSync, and HDMI control.
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,
and Blu-ray disc which are copyright protected with HDCP 2.2.
Front-Panel HDMI (MHL) Port: The front-panel HDMI port is
designed for the connection of select mobile phones and other portable
electronic devices using the new MHL standard. Simply plug your MHL compatible
smartphone into the receiver's front-panel HDMI port using the HDMI cable that

video inputs (3 rear/1 front), one composite video record output, one composite video monitor output, and one Zone
2 composite video output. The composite video monitor output can also be
assigned to Zone 3. There are also three component video (60MHz) inputs, one component video
monitor output, and one Zone 2 component video output.
12-Bit I/P Converter & Scaler (4K): The
AVR-4520CI is equipped with a 12-bit i/p converter & scaler that converts
incoming analog video signals to HDMI and scales them to a higher resolution, so
only one video connection is required from the receiver to the TV. HDMI input
video signals can also be scaled to a higher resolution. The receiver's multi-zone HDMI output does not support
analog-to-HDMI conversion. The scaled output resolution
is set in the receiver's menu.
- Composite Video to HDMI: Composite video signals (480i only) can
be scaled to 480p, 720p, 1080i, 1080p, or 4K through the receiver's HDMI
- Component Video to HDMI: Component video signals
(480i/480p/720p/1080i/1080p) can be scaled to 480p, 720p, 1080i, 1080p or 4k
through the receiver's HDMI output.
- HDMI to HDMI: HDMI video signals (480i/480p/720p/1080i/108p/4K)
can be scaled to 480p, 720p, 1080i, 1080p, or 4k through the receiver's HDMI
Note: You can also convert a composite video signal to a
component video and vice-versa (without scaling). HDMI can only be output
NSV (Noise Shaped Video): The NSV precision video feature
works in the digital domain to reduce noise in the video signal frequency band
in order to enhance video signal linearity, provide the most accurate signal
representation, and enhance the picture quality. Noise shaping techniques can be
combined with dynamic element matching techniques in order to reduce the
matching requirements of DAC elements by converting the analog mismatch into out
of band noise. This approach of dynamic element matching and noise shaping has
been shown to allow the use of sigma delta modulation at video data rates. NSV
is the only product on the market that can achieve ultimate precision with
12-bit fidelity in both digital-to-analog and analog-to-digital domains.
3D Pass-Through: With the advent of 3D media, it is important
to own a receiver that recognizes 3D video signals. The AVR-4520CI 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-4520CI, you will have a 3D home theater where you can enjoy high-definition
sound and video on a level you've never experienced before.
