Leaving the analog/digital division far behind  this digital preamplifierfeatures ultra high-speed DSP and complete readiness for the newgeneration of super high quality audio sources. The newly developed
MDS (Multiple Delta Sigma) converter with 24-bit ultra high precision
resolution results in dramatically enhanced performance. Witness a new
dimension of audio perfection.
The DC-330 builds on the foundation of the
DC-300, with some significant advantages overits predecessor. Ease of use has been further
enhanced, and latest digital technology andredesigned circuitry assure total compatibility
with the emerging new generation of top-quality
audio sources such as SACD and DVD-Audio.
The digital volume and tone controls function
with previously unattainable precision, yet theirsmooth operation feel is on a par with the bestof analog equipment. Internally, the DC-330
features ultra high-speed digital processing
performed by a latest-generation DSP device.
D/A conversion is handled by an innovative MDS(Multiple Delta Sigma) converter which boasts
superior accuracy. This makes the DC-330
capable of bringing out the full potential of a
new breed of audio sources that is justemerging, such as the Super Audio CD (SACD)
and DVD-Audio. During the development of thisamplifier, countless listening sessions were held
to arrive at the detailed, rich sound that is ahallmark of every Accuphase product.
In a preamplifier, the part that has a decisive
influence on the sonic end result is the section
where adjustments such as volume, tone, andloudness compensation are carried out. In thedigital DC-330, this task is handled by anextremely fast DSP that assures a drastic leapin performance, achieving outstanding
signal-to-noise ratio, amazing channel
separation, and totally negligible distortion. The
overall result is utterly natural and realistic soundwith full control over every vital aspect.
To provide complete flexibility with a view tofuture expansion, all inputs and recording

outputs of the DC-330 are implemented as
option boards. The option board slots support
the ADB2 (Accuphase Digital Bus 2) interface
which accommodates also formats such as
SACD and DVD-Audio. The DC-330 comes witha line input board for analog signals and a digital
input/output board installed as standard
equipment.
As a perfect blend of analog operation feelingand sophisticated digital technology, the DC-330
transcends the mechanistic division of “analog”
or “digital”, fusing them both into a higher
dimension that is devoted solely to theenjoyment of music.
Fully digital preamplifier with ultra
high-speed DSP and support for highsampling rates: 2.8224 MHz/1-bit and 192
kHz/24-bit.
Figure 1 shows the block diagram of the DC-330.
Digital sources are connected via coaxial or
optical inputs located on option boards. All
option board slots of the unit are ready to handle
the bit stream output of a SACD player whichuses 2.8224 MHz/1-bit,
as well as the 192 kHz/
24-bit signal used for
DVD-Audio.
Otherhigh-quality formats that may emerge will alsopose no problem to the DC-330. After the input,

switching. All ofthese adjustments are accomplished entirely inthe digital domain.
An ultra high-speed “isolated digital coupler”
ensures effective electrical separation between
the digital section encompassing the DSP and
the D/A converter and subsequent analog
segments of the amplifier. After digital volume,balance, and attenuation processing, the signal
reaches the newly developed MDS type D/Aconverter which produces an analog signal ofutmost precision. A 3-pole linear phase low-passfilter then removes any remnants of the digitalprocess, before sending the signal to thebalanced and unbalanced outputs.

an impressive sense of clarity and nuance.
Volume control with smooth analog feel
A massive knob on a precision-machined shaft
rotates a disc with star-shaped slits which

generate a series of pulses ina phase detector. These
pulses are utilized by amicroprocessor to govern thevolume control function. For the user,
the volume control of the DC-330 operates
with a silky smooth and natural feel that perfectly
matches the audible change in volume. The
current volume setting is indicated by thenumeric display and also by an array of LEDs
on the circumference of the control. This lets
you check the setting at a glance.
Linear phase analog filters provide superior
characteristics
The analog filter, which serves to remove
aliasing noise in the extreme upper frequency
range, is a 3-pole linear phase type filter withoutstanding phase characteristics. The cutoff
frequency is optimized to minimize phase shift
within the passband. Strict selection of all filter
components assures sonic purity and totalmusical accuracy.
