PREMIUM CD/SACD PLAYER WITH ADVANCED AL32
PROCESSING PLUS FOR PURE PERFORMANCE

Denon is one of the rare audio brands that continued to actively develop
HieFi components and accumulate, refine, and pass down HieFi audio
technologies The 2500NE series, designed for todays age, has been
developed by both veteran engineers and talented young engineers
who have inherited the Denon technologies and expertise that have
been cultivated over many years and decades. The DCD72500NE
focuses on achieving the essence of a disc player: ultraehigh precision
in reading discs and supplying highequality audio signals to the amp.
To achieve this, the signal paths are as short as possible and the

whole circuitry is minimized. The engineers also redesigned the disc
drive mechanism brackets and the chassis to eliminate vibration, the
great enemy of disc players, and achieve ultraevibrationeresistant
performance. The information on the disc is now read with impece
cable accuracy and a clean, highegrade signal is supplied to the
DOD725OONEs Advanced AL32 Processing Plus circuitry. Besides
CD and Super Audio CD playback, the DOD features playback of
audio recordings up to PCM192/24 or DSD5.6 recorded on a DVD
R/RW for full flexibility and extended access to high resolution audio.

Advanced AL32 Processing Plus and high precision
32-bitl192kHz D/A converters, to dramatically enhance the
music listening experience

The DCDVZEOONE is equipped with Advanced AL32 Processing
Plus, the latest version of Denons analogue waveform repror
duction technology which utilizes unique data interpolation
algorithms and also supports highrresoiution sound sources.
These algorithms interpolate points that should exist before and
alter the points in large quantities of data to achieve a smooth
waveform that is close to that of the original signal. By carefully
restoring data that was lost during digital recording, the resulting
playback sound is highly detailed, free of interference, accurately
localized, richly expressive in the lower range, and beautifully
faithful to the original sound.

Highrprecision 32bit, 1927kHz D/A converters have been used
to bring out the maximum performance of the Advanced AL32
Processor. These D/A converters transmit differential output to
each channel to improve sound quality during playback.

DSD data disc playback support

in addition to CD and Super Audio CD, the DCDVZSOONE can play
DSD (2.8 Mhz / 5.6 MHz) files and highrresoiution files up to
192 kHz / 24 bits recorded on DVDrR/RW and DVD+R/HW discs.
Music files with sampling frequencies of up to 48 kHz recorded
on GDrR/RW discs can also be played.

Independent digital and analogue power transformers

The power units for the digital and analogue circuits, whose sign
nais have different characteristics, have separate transformers to
eliminate mutual interference and noise. An aluminum plate has
also been combined to the underside of the steel transformer
base to strengthen rigidity.

Advanced S.V.H. Mechanism, Denon's original

disc drive design

The DCDVZEOONEs disc drive is the same Advanced S.V.H.
Mechanism that is used in highrend models. The circuitry that
controls the pickup and decodes the signals read from the disc
has been newly developed. Signal paths have been shortened
to an absolute minimum and circuits have been miniaturized to
ensure that excess current or noise will not occur. The various
parts of the mechanism have been made with different materials
such as a combination of stainless and copper plating for the top
panel to strengthen rigidity, diecast aluminum for the disc tray,
and 2mm thick steel for the mechanism brackets. improvements
in highemass, vibrationrresistant properties and the dispersal
of resonation points contribute to a high level of vibration re
sistance. in addition, the mechanisms low center of gravity
suppresses any vibration occurring inside the mechanism due
to disc rotation, and the mechanism structure also effectively
suppresses external vibration. By eliminating unwanted vibration,
servorreiated operations are minimized, and by also minimizing
unnecessary controls and cunent consumption, digital signals
can be read from the disc with optimum accuracy under stable
conditions.

DAC Master Clock Design

To accurately synchronize digital circuits, the DGDVZEOONEs
DAC Master Giock Design treats the DAC as the master when
clock signals are supplied. Positioning the master clock imr
mediateiy adjacent to the D/A converter (DAG) suppresses jitter
and ensures optimum precision in D/A conversion. in addition,
the quality of the clock, which becomes the reference for semir
conductor operation, is extremely important for ensuring that
the digital audio circuitry performs at its maximum potential.
The DGDVZSOONE thus employs a clock oscillator to dramatically
reduce phase noise that is the displacement of frequencies.
The clock power circuit has also been vastly improved to bring
out the full potential of the highrquaiity ciocks performance. A
conductive polymer capacitor with particularly outstanding high
frequency impedance characteristics for Denon's renowned
sound quality has been placed at the base of the clocks power
source, and an ultrarcompactliim capacitorthat is different from
layered ceramic capacitors has been placed close to the clock,
to achieve an improved SIN ratio and a transparent sound with
superior spatial expression. The DGD725ODNE is equipped with
two clock oscillators, one for each sampling frequency (44.1 kHz
and 48 kHz), that can be swrtched between the frequencies to
thoroughty suppress jitter.

Vibration»resistant design with Direct Mechanical Ground
Construction

The chassis has been designed throughout to eliminate the ad
verse effects on sound quality caused by subtle vibrations from
the players interior or by external vibrations from the speakers.
