Dynamic Discrete Surround Circuit

D.D.S.C.-HD DIGITAL

Denon’s AV amp design concept is to

“reproduce the sound exactly as intended

by the movie producers” and to achieve

that we have taken the signal processing

circuits required to accomplish this and put

them in individually independent blocks

to make them discrete using specialized

circuits. These circuits are conﬁgured and

carefully tuned to provide the same power,

response, and quality for all channels

to reproduce high-fidelity sound that is

comparable to pure audio.

The latest 32-bit floating point DSP is used

on the decorder — the heart of the digital

circuit.

A master clock design that generates a

high accuracy clock is placed close to

the D/A converter that converts the digital

signal into a music signal. This suppresses

residual jitter generation and clearly

reproduces the audio image proﬁle.

Denon Link HD Reproduces All

Signals with High-Fidelity

Using the HDMI standard where signals

are transmitted using a packet method

it is easy for jitter to occur frequently in

the clock, the standard for digital/analog

conversion, which induces offset in the

regenerated waveform and thus inhibits

accurate music reproduction.

Denon addressed this problem early on by

developing and incorporating Denon Link

as a proprietary transmission standard.

In 2012, Denon Link was upgraded

to the more powerful Denon Link HD.

This successfully eliminates jitter during

transmission by connecting an HDMI cable

and a special clock synchronous cable to

supported Blu-ray players to completely

synchronize the clock between the AV amp

and the player. In addition to Blu-ray, this is

also effective during DVD, CD, and Super

Audio CD audio transmissions allowing you

to enjoy your favorite contents at maximum

quality regardless of the media.

Power Stage Uses a Discrete

Conﬁguration to Reﬁne the Sound

This power stage is equipped with a power

amp uniquely configured of carefully

selected components to produce rich sound

not possible using ICs or power packs.

To bring out the maximum potential of the

connected speakers by getting the full

performance from the power amp we have

equipped it with a power supply that utilizes

high speed rectiﬁer diodes and high capacity

block capacitors.

All Models

This new-generation AV Surround Receiver puts high-definition

4K display age high image quality and high sound quality

technology into a solid, well-designed body.

Suppresses Jitter Occurrence

for All Devices

Hybrid PLL Jitter Reducer

Jitter in the clock used as the standard for

digital/analog conversions will cause offset

in the regenerated waveform, preventing

accurate regeneration.

Denon’s unique clock jitter reducer

decreases jitter occurrence by comparing

the input signal and output signal phases.

Further, many general jitter suppression

functions only support digital signals

whereas Denon’s Clock Jitter Reducer

works effectively for all input signals to

be digitally processed (including analog

signals), so you can enjoy high-fidelity

sound from all sources.

Alpha Processor

Denon’s proprietary technology, the Alpha

Processor, was originally developed as

technology for extending 16-bit CD audio

to 20-bit accuracy and has been well

received by many pure audio users. The

AVR-3313 extends PCM digital signals on

all channels to 24-bit accuracy. The AVR-

4520 is also capable of extending PCM

and bit stream signals such as Dolby and

DTS to 32-bit. The original sound of the

recording location is reproduced as faithfully

as possible by interpolating the signal lost

during digitalization.

Direct Mechanical Ground

Construction & Minimum Signal Path

Thorough anti-vibration construction is used

to suppress the effect of vibration on image

and sound quality. The signal circuit has also

been simplified and shortened to prevent

signal degradation from the way circuitry

is routed.

All Models

Good Sound from Compressed Audio

Compressed Audio Restorer

Compression processing, such as WMA,

MP3, and AAC, omits the sounds that

are difficult for humans to hear. The

compressed audio restorer regenerates

the omitted signal to restore and play the

pre-compression sound as close to the

original sound as possible. Richer music

playing is made possible by generating the

high frequency signal that tends to be lost

during compression while correcting the

low range depth.

Surround Sound Settings

Audyssey MultEQ XT/XT32

Unlike a movie theater, there is a wide

variation in the viewing environments in

homes. The included microphone is used

to measure the room environment and

then automatically check the speaker

settings and make basic settings as

needed. The Audyssey sound field

correction technology focuses on the

room’s acoustic echo characteristics. This

suppresses unnecessary reflected sound

that causes sound turbidity, such as the

difference in the echo characteristics

between the right and left and other

walls or the flutter echo between the

ceiling and floor, which are problems

that tend to occur easily during playback

at home because making corrections

is difficult using a general equalizer.

A maximum of 8 locations can be

measured to provide the optimum surround

sound experience at any viewing point even

when many people are viewing such as

during movies.
