In 2008, Accuphase released DP-600 as a standard
model to playback both SA-CD and CD.
The new DP-570 is the 4th generation of this line withimproved SA-CD/CD drive and ultra low THD and noise
performance, compared to the former DP-560 which wasreleased in 2016.
In order to pursue the accurate data reading, the vibration
analysis of the laser pickup is performed, and the careful
design including the housing thoroughly eliminates theadverse effect on the disc reading.
Equipped with a USB input that supports various digitalsources.
Combining the latest technology and reliability, the DP570 will be a way to extract all information contained inyour SA-CD / CD collections and will take you to the next
step in the ideal disc playback experience.

DP-570 can show the sampling frequency and thenumber of effective bits of all input signals on the front
display.

DP-570 is applied the 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 the analog
circuit is on the left side at the rear panel.
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.

Large bridge cover is very effective to reduce the motion
noise coming from the motor drive and the disc rotation.
This cover is three storied parts, molded base, ironinsulator, and aluminum cover. There are uncountable air
gaps between each materials to absorb the vibrations.
Furthermore, laser pickup module is mounted on thevibration absorbers. Those are made of the butyl rubber
which is carefully selected from many kinds of rubbermaterials specially for this mechanism.

4In order to accurately read the signal engraved on thedisc, it is important that no extra vibration is transmitted tothe pickup module.
In addition to the external vibration, the internal vibration
coming from the high-speed disc rotation or the powertransformer should be shielded.
The development team of DP-570 performed thevibration analysis to decrease resonance points so thateven minute vibrations generated from inside the chassis
does not affect the reading accuracy.

Ultra Low Noise is one of the main technical features ofDP-570.
The former model, DP-560 still has the excellent noiseperformance, however, DP-570 achieves 12% loweroutput noise voltage than DP-560.
DP-570 guarantees 120dB Signal to Noise ratio whichmeans 2.5μV of output noise voltage.

DP-570 proudly shows the great THD+Noisecharacteristics which are quite important for music
playback, and this clearly proves that DP-570 obtains the30% lower THD+Noise characteristics than DP-560.

For D/A converter section, Accuphase updates the DAC
chip to ESS Technology’s 32bit Hyper StreamⅡ DAC
ES9028PRO for DP-570. This is the same DAC as in DP750.
ES9028PRO has 8 DACs inside, and DP-570 uses 4DACs connected in parallel per channel with Accuphase’s
unique technology, MDS+ conversion system.
Fully-balanced structure is employed after D/A converter
section in DP-570.
In addition, the independent low pass filter is installed foreach audio output, thanks to this, the sound signals fromall the outputs become high quality.

8DP-570 has 4 digital inputs, Coaxial, Optical, HS-LINKand USB.
USB Input accepts 384kHz/32bit-PCM or 11.2896MHzDSD. DSD data can be received both DoP（DSD overPCM）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 comesto be able to transmit and receive up to 384kHz/32bitPCM, 5.6448MHz-DSD.
DP-570 automatically recognizes either Ver.1 or Ver.2
transmission.

9HS-LINK Version 2 extends the HS-LINK standard.
For backward compatibility, DP-570 is still available HSLINK Ver.1 output.

10

The biggest feature of HS-LINK Ver.2 is sending themusic signal and the master clock separately to D/Aconverter in a receiver.
HS-LINK Ver.1 sends the music signal merging themaster clock together, the PLL circuit to recover themaster clock needs to be located at the receiver side.
Since master clock has been transmitting as it is, in HSLINK Ver.2, not only master clock recovery is
unnecessary at receiver side but it comes to be free fromthe jitter at the PLL circuit.

11DATA Disc playback is available.
You can record music files on blank DVD by using yourPC.
DP-570 can play 192kHz 24 bit data of WAV, FLAC,AIFF format, and 5.6MHz 1bit DSD data also.
You can enjoy many kinds of digital data with DP-570.

DP-570 applied the aluminum “hair-line” finished topplate. It brings an elegant atmosphere with gray metal
finished side panels.
DP-570 also provides a programable playlist feature,It allows you to enjoy listening in the order you prefer.
