Accuphase Opens Up Another Dimension in Pure Audio
Separate Type SACD Player
for a Superb New Medium: Super Audio CD.
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 other
current 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.
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 and
✽✽
documentation for that model.
The DG-28 can handle 48-kHz/24-bit signals and perform equalization up to
a 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.

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 the
data supplied by these high-quality sources, the
DC-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 first
developed 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.

Versatile processor features HS-Link input as standard equipment, for

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.
MDS (Multiple Delta Sigma) converter reduces distortion to theoretical limits and
assures outstanding S/N ratio
MDS (Multiple Delta Sigma) is a revolutionary
design which employs several delta sigma type
converters in a parallel configuration, resulting
in drastically improved accuracy. The
delta sigma principle
combines
oversampling with
noise-shaping (a kind
of digital feedback)
which projects the
amplitude information of the digital signal onto
a time axis for precise conversion.
Figure 1 shows several delta
sigma converters which are
fed with the same signal
and whose outputs are
combined to arrive at
the overall wave-
form. In the DC-101, six delta sigma convert-
ers are operated in parallel, resulting in
a performance improvement by a
factor of 2.45 (=√6 ).
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 used
which generates a master clock to be used as
system reference.
As shown in the diagram, the Ultra Jitter-Free
PLL Circuit of the DC-101 consists of a
preamble detector
and a voltage-controlled oscillator (VCO)
using a quartz crystal
element. The master
clock produced by
this PLL circuit is totally free from the effects of pulse distortion and
jitter.
D/A converter with printed circuit boards
made from Teflon (glass fluorocarbon resin)
with low dielectric constant and low loss
The D/A converter boards use a substrate of
glass fluorocarbon resin which has a stable, low
dielectric 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
HS-Link block diagram
SACD/CD transport with dedicated digital output and HSLink: the ultimate digital audio interface. Stationary optical
assembly with dual pickups assures absolutely pure digital
signal readout. Top loading principle with smooth sliding
door.
A new era is about to unfold in the history of
audio. The Super Audio CD offers a way to
experience music like never before. Accuphase
offers 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 a
sampling 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 are
clearly the best approach. Accuphase presents
two components that can take SACD to the
heights it is designed for. And to make sure that
nothing is lost in the transfer stage, the two
components are linked by a new type of digital
DP-100 Features

interface called HS-Link. This interface standard developed by Accuphase is ideal not only
for new sources like SACD and DVD-Audio, it
also 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 much
to look forward to.
The HS-Link interface uses a dedicated cable
which can carry both upstream and downstream
data. This makes it possible to use an
unobtrusive signal verification system that
assures full copyright protection for musical
material. Using HS-Link, the DP-100 can be
combined with other current Accuphase
components 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 create
a multi-amped system that takes digital audio
to sonic heights such as never experienced
before.
