The DP-800/DC-801 SA-CD/CD player enters the fi eld as the desig-
nated successor to the DP-100/DC-101 model pair. The DP-800 is the
transport, featuring a newly developed, ultra-massive SA-CD/CD drive
designed for high rigidity and utmost precision. The DC-801 processor
boasts a totally new approach to digital signal handling called MDSD,
which enables straight D/A conversion of the DSD signal. Revolu-
DP-800/DC-801 connection
A single HS-Link cable carries
both the SA-CD and CD signal.

m Connection is possible to any com-
ponent with a built-in HS-Link interface or an HS-Link option board,
such as DP-100, DC-101, DC-330,
DP-85, DP-78 etc.

tionary Accuphase technology paired with our famous dedication to
sonic excellence fi nally brings out everything the SA-CD format has
to offer. The two components are connected via HS-Link cable, using
Accuphase’s exclusive high-quality digital interface HS-Link. Connecting a DG-38 for sound fi eld processing in the digital domain is also
possible.

A digital recorder can be connected for recording/playback of
sources other than SA-CD
Coaxial cable
m The SA-CD/CD signal supplied via HS-Link
does not appear at the DIGITAL OUTPUTS
and therefore cannot be recorded digitally.
To record the CD signal from the DP-800
digitally, use a coaxial connection.

MDS++ D/A Converter with eight circuits operating in parallel
The D/A converter that forms part of the MDSD type moving-average fi lter circuit is an MDS++ D/A
converter with an amazing eight circuits operating in parallel, ensuring the utmost in accuracy and sound
quality.
MDS (Multiple Delta Sigma) is an innovative approach that employs several delta sigma type converters
in a parallel confi guration for greatly improved accuracy. Combining the output signal from individual
converters causes mutual cancellation of conversion errors, resulting in a notable improvement in all
relevant aspects of conversion performance: accuracy, S/N ratio, dynamic range, linearity, and THD.

Ultra Jitter-Free + PLL circuit
The output of any D/A converter contains so-called aliasing noise in the very high frequen-
DAI signal input
The operation of the D/A
converter must be synchronized with the digital input
signal. For this purpose, a
phase-locked loop (PLL)
circuit is used to extract the
master clock which is used
as system reference. In the
DC-801, this important task
is handled by a further improved circuit called Ultra
Jitter-Free + PLL.

cy range. An analog fi lter designed to remove that noise is therefore always required. The
fi lter circuitry in the DC-801 uses 5-pole Butterworth analog fi lters with extremely fl at fre-
quency response in the passband. In order to prevent unwanted interaction, the low-pass
fi lter confi guration is completely separate for the balanced and unbalanced signal paths.
