DP-100 Application Examples
To connect the DP-100 to other equipment for wide
frequency range/wide dynamic range reproduction of a
SACD source, an HS-Link interface is required. Using
HS-Link, the DP-100 can also be connected to othercurrent Accuphase components besides the DC-101,
such as the Digital Preamplifier DC-330 and the DP-85,
DP-77, or DP-75V. By installing other option boards,
combination with components such as the Digital
Voicing Equalizer DG-28/DG-38 and the Channel Divider
DF-35 also becomes possible. This opens up a variety
of ways to enjoy high quality music media.

HS-Link Input Board DI2-HS1
This board serves for input of the digital signal corresponding to the HS-Link interface.
• Installed as standard equipment in the DC-101.
• Serves for connecting the DP-100 to the DC-330, DP-75V, etc.
• Requires a dedicated HS-Link cable, such as the HDL-15 fromAccuphase.
• Uses two slots.

HS-Link Output Board DO2-HS1
This board serves for output of the digital signal corresponding to the HS-Link interface.
• By installing this board in the DC-330, the signal from theDP-100 can be sent on to the DF-35 in digital form.
• Requires a dedicated HS-Link cable.

* The HS-Link cable is supplied with the DP-100.

Combination Example of DP-100 With DG-28✽ For information on combination with the DG-38, see the catalog anddocumentation for that model.

Wide Range Analog Input/Output Board for DG-28

The DG-28 can handle 48-kHz/24-bit signals and perform equalization up toa threshold of 24 kHz. For high sampling frequency signals exceeding 48 kHz
such as from SACD, a "Wide Range Digital Input/Output Board for DG-28
Connection" is required.
Only the signal components in the audible range up to 24 kHz are sent to the
DG-28 for equalization. The signal components above 24 kHz are routed
directly to the output using a high-pass filter. The equalized signal from the
DG-28 is mixed to the bypassed components and then returned in digital form.

Precision Digital Processor

Versatile processor features HS-Link input as standard equipment, for
SACD reproduction without compromise. Compatible with latest
generation of super high quality sources such as SACD and DVD-Audio.
Revolutionary MDS (Multiple Delta Sigma) converter with 24-bit
resolution assures superior precision. Ultra jitter-free PLL circuit topology.

Ultra Jitter-Free PLL Circuit
For the purpose of synchronizing operation of
the D/A converter with the digital audio interface(DAI), a phase-locked loop (PLL) circuit is usedwhich generates a master clock to be used assystem reference.

DAI input signal

The DC-101 is a digital processor incorporating latest digital technology to handle new generation formats such as SACD (2.8224 MHz/1
bit) or DVD-Audio (192 kHz/24 bit). From thedata supplied by these high-quality sources, theDC-101 extracts a music signal of the utmost
purity.
The crucial step of turning the digital information
into analog form is handled by an MDS (Multiple
Delta Sigma) converter. This principle was firstdeveloped for the DC-330 and affords absolutely
outstanding conversion precision. To assure
flexibility and allow future expansion, all inputs
to the DC-101 are handled by option boards.
An HS-Link input board and a regular digital
input/output board are provided as standard
equipment.

The D/A converter boards use a substrate ofglass fluorocarbon resin which has a stable, lowdielectric constant as well as superior heat resistance and high-frequency characteristics.
Using this material for the audio circuitry assures signal transmission with utmost purity,
resulting in a clear improvement in perceived
signal-to-noise ratio. In the DC-101, gold-plated
copper traces further contribute to sonic purity.

Super Audio CD Transport

A new era is about to unfold in the history ofaudio. The Super Audio CD offers a way toexperience music like never before. Accuphaseoffers a no-holds-barred separate type player
solution that lets the new medium develop its
full potential: Transport DP-100 and Digital
Processor DC-101.
Whereas the conventional CD operates with asampling frequency of 44.1 kHz and 16-bit resolution, the Super Audio Compact Disc (SACD)
employs a 2.8224 MHz/1-bit format which enables it to hold four times more information. To
make optimum use of the wide frequency range
and dynamic range capabilities of this exciting
new medium, separate type components areclearly the best approach. Accuphase presents
two components that can take SACD to theheights it is designed for. And to make sure that
nothing is lost in the transfer stage, the twocomponents are linked by a new type of digital

SACD/CD transport with dedicated digital output and HSLink: the ultimate digital audio interface. Stationary opticalassembly with dual pickups assures absolutely pure digital
signal readout. Top loading principle with smooth sliding
door.
interface called HS-Link. This interface standard developed by Accuphase is ideal not only
for new sources like SACD and DVD-Audio, italso can benefit existing digital audio components such as CD players or MD and DAT recorders. Future possibilities are just now beginning to unfold, giving the true audiophile muchto look forward to.
The HS-Link interface uses a dedicated cablewhich can carry both upstream and downstream
data. This makes it possible to use an
unobtrusive signal verification system thatassures full copyright protection for musicalmaterial. Using HS-Link, the DP-100 can be
combined with other current Accuphasecomponents such as the Digital Preamplifier
DC-330 and the DP-85, DP-77, or DP-75V. In
conjunction with the Digital Voicing Equalizer
DG-38 or DG-28 (using wide-range option
boards for DG-28), sound field compensation

for wide-range sources is possible. By
configuring an HS-Link chain consisting of
DP-100 c DC-330 c DF-35, you can createa multi-amped system that takes digital audio
to sonic heights such as never experienced
before.

HS-Link — High Speed Link
HS-Link makes use of extremely sophisticated digital signal transmission technology. Accuphase developed
this standard in order to allow reproduction of digital sources with superb sound quality. A single cable is usedboth to send and receive verification information for copyright purposes and to deliver the audio data stream
without the slightest deterioration.
