Accuphase DP-560 User manual

DP-560 is a succession model of DP-550.
Technical high lights of DP-560 are newly developed
SA-CD drive and ultra low THD and noise performance.
They are inherited from our flagship SA-CD transport
DP-950 and digital processor DC-950.
1

DP-560 can show the sampling frequency and the
number of effective bits of all input signals on the front
display.
2

The dimension of DP-560 is as same as those of DP-550.
The weight becomes slightly heavier than DP-550. This
is due to the reinforcement of power supply circuit and
new SA-CD drive mechanism.
3

The Bridge cover of SA-CD drive mechanism is bigger
and longer than that of DP-550. This is very effective for
reducing noise caused of motor drive and air flow by disc
rotation. This cover is three storied parts, molded base,
iron insulator, and aluminum cover. There are
uncountable air gaps between each materials to absorb
vibration.
Furthermore, laser pickup module is mounted with
vibration absorbers. Those are made of the silicon which
is selected from many kinds of silicon materials for this
mechanism.
By these complete techniques, total noise level you hear
has been reduced dramatically. It become less than one
third of DP-550. In fact, you can hear nothing.
4

DP-560 is applied systematical layout. Each circuit block
is logically placed to make the signal path short as
possible.
The digital circuit is on the right side and analog circuit is
on the left side at the back panel side.
Logic control board is on the right side of SA-CD drive
mechanism, and on the left side, reinforced power supply
is installed with the power transformer.
5

Ultra Low Noise is one of the main technical features of
DP-560.
The former model, DP-550 has the excellent noise
performance, however, DP-560 achieves 20% output
noise voltage lower than DP-550.
DP-560 guarantees 119dB Signal to Noise ratio which
means 2.8μV of output noise voltage.
6

DP-560 proudly shows the great THD+Noise
characteristics which are quite important for music
playbacks, and this clearly proves that DP-560 can stand
comparison with our flagship digital processor DC-950.

For D/A converter section, Accuphase updates the DAC
chip to ESS Technology’s 32bit Hyperstream DAC
ES9018S for DP-560.
ES9018S has 8 DACs inside, and DP-560 uses 4 DACs
connected in parallel per channel with Accuphase’s
unique technology, MDS+ conversion system.
Full-balanced structure is employed after D/A converter
section in DP-560.
In addition, the independent low pass filter is installed for
each audio output.
Due to this, the sound signals from all the outputs
become high quality.
8

DP-560 has 4 digital inputs, Coaxial, Optical, HS-LINK
and USB.
USB Input accepts 384kHz/32bit-PCM or 11.2896MHz-
DSD. DSD data can be received both DoP（DSD over
PCM）and ASIO2.1.
HS-LINK has been evolved into Version2.
Original HS-LINK(Ver.1) transmits and receives only
192kHz/24bit-PCM or 2.8224MHz-DSD, but Ver.2 comes
to be able to transmit and receive 384kHz/32bit-PCM,
5.6648MHz-DSD.
DP-560 automatically recognizes either Ver.1 or Ver.2
transmissions.
9

HS-LINK Version 2 extends the HS-LINK standard.
For backward compatibility, DP-560 is still available HS-
LINK Ver.1 output.
10

The biggest feature of HS-LINK Ver.2 is sending the
music signal and the master clock separately to D/A
converter in a receiver.
HS-LINK Ver.1 sends the music signal merging the
master clock together, PLL circuit for master clock
recovery is needed at receiver side.
Since master clock is been transmitting as it is, in HS-
LINK Ver.2, not only master clock recovery is
unnecessary at receiver side but it comes to be free
from the jitter at PLL circuit.
11

DATA Disc playback is available.
You can record music files on blank DVD by using your
PC.
DP-560 can play 192kHz 24 bit data of WAV, FLAC,
AIFF format, and 5.6MHz 1bit DSD data also.
You can enjoy all kinds of digital data with DP-560.
