The Technology of Precision

Features and Functions of Transport Section■ Highly rigid and precise construction with newly developed SA-CD/CD
drive and sturdy, heavyweight chassis to absorb external vibrations.
The SA-CD/CD drive employs a high-stiffness construction that not only
minimizes vibrations from internal rotation but also absorbs any
external vibrations, whether large or small. The mechanical base is fully
integrated with the massive and highly rigid chassis.

Large bridge cover■ Floating type traverse mechanism.
Mechanical isolation between the traverse mechanism and theloading mechanism is provided by newly developed silicone typeviscous dampers whose shape and material composition have been
carefully optimized. Four of these are used to realize a floatingdesign.

Viscous dampers■ Dramatically enhanced quietness of operation.
Even though they may appear flat to the unaided eye, media discs often haveslight eccentricities in dimensions and weight, as well as warping. When
spinning at high speed, this leads to various types of vibrations and wind noise.
Based on thorough research into these issues, the DP-560 features astrengthened rotation system and effective vibration frequency control, alongwith further improved vibration insulation. To combat wind noise, a larger bridge
enabling air flow control is used, along with various other technology based
measures that result in a significant improvement in quietness. Disc rotationnoise is reduced to about one third as compared to earlier designs.
■ Large bridge cover.
The shape design of the bridge takes aspects such as air vibrations and air flowcaused by the rotation of the disc into consideration, to effectively curb noiseand vibrations from the media rotating at high speed. In addition, the bridge itself
employs a 5-layer structure that also helps to block noise.
■ Low center of gravity for effective control of vibrations and resonances.
■ High-quality disc tray extruded from an aluminum block, plus super-quiet
and smooth disc loading mechanism.
■ Reinforced disc chucking design reduces wobble.

Features and Functions of Digital Processor Section■ High-performance Hyperstream DAC chip
ES9018S from ESS Technology Inc.
■ MDS+ type D/A converter with four parallel circuits.
MDS+ is a revolutionary approach that employs
multiple delta-sigma type D/A converters connectedin parallel for drastically improved performance. Thesame digital signal is supplied to each converter, andthe output of the converters is summed before being
ES9018S DAC chip
sent to subsequent stages. In the DP-560, fourconverter circuits are used in parallel. Compared to a single converter circuit,this results in an overall performance improvement by a factor of 2 (= √4).
Because the performance improvement afforded by the MDS principle isindependent of signal frequency and signal level, output signal noise at very
low levels is also successfully minimized, a feat that is very difficult to achievewith conventional delta-sigma converters.
■ Direct Balanced Filter configuration for analog filter.
The analog filter designed to remove so-called aliasing noise in the very high frequency
range employs 5-pole Butterworth analog filters with extremely flat frequency responsein the passband. In order to prevent unwanted interaction, completely separate
low-pass filters are provided for the line and balanced signal paths.
■ High-performance audio interface chip AK4118A for drastically reduced jitter.

Advanced Features■ Power supply optimized for performance and sound quality.
The power transformer is a newly designed type withseparate windings for supplying the analog section and thedigital section. The power supply circuitry for the analog
section employs a discrete configuration for low noise andhas been specially tuned for optimum performance andsound quality.
■ Display can show sampling frequency and number ofquantization bits.
Besides indicating track numbers and elapsed playing
time, the display can also show the sampling frequency
and the number of quantization bits when using theexternal input and during transport operation.
■ Digital level control allows adjustment down to –80 dB.
The level control employs the digital principle for optimum
accuracy and minimal degradation of sound quality.
Integration of the level control function in the D/A converter
prevents noise and provides a wide adjustment range
down to –80 dB.
■ Playback of data on discs such as self-recorded DVD
media supported.
CD-R/-RW, DVD-R/-RW/+R/+RW(Supported formats: WAV, FLAC, DSF, DSDIFF)■ Versatile array of digital inputs and outputs
including HS-LINK (Ver. 1 and Ver. 2), COAXIAL,OPTICAL, and USB (input only).
To utilize the high performance of the built-in processing
section, data from other digital equipment can be supplied
to the DP-560 via the digital inputs and played back withhigh sound quality.
■ Triple layer bottom plate and carbon cast ironinsulator feet with superior damping characteristics
absorb vibrations for further enhanced sound quality.
■ Analog outputs provide a choice of line level and balanced
types for shutting out external noise interference.
■ Phase selector for balanced output.
