PMA-1510AE

Integrated Ampl er

Rich sound from various music sources thanks to
UHC-MOS single push-pull output circuit

The PMA-1510AE is endowed with a renowned Denon tradition: the simple & straight UHC-MOS single push-pull amplifier
circuit. Amplifier construction, the foundation of expressive sound, has also been redesigned to place greater emphasis on
low speCific gravity and more direct grounding. Rich musical expressiveness in a class of its own is achieved With the same

large, 27-mm motor-driven volume control thats used on the high-class PMA-ZOiOAE.

High quality sound

Ultra-High Current (UHC)-MOS Single Push-
Pull Circuit, for balancing details and power
The PMA71510AE features UHC (Ultra High Cure
rent) aMOS technology that utilises a minimum
number of highacurrent amplifier elements to bale
ance advanced speaker drive capabilities and
improved sound quality. UHCVMOS is an ideal
amplifier whose power supply performance is sue
perior to that of bipolar transistors and incorporates
the sound quality advantages of li/lOSaFEls. The
PMAalSlOAE's UHCali/lOS is provided in a single
pushapull configuration that eliminates deviations
in the amplification stage and balances high power
With delicate musical details. This circuit masterfully
reproduces the full sonic range, from the delicate
musical nuances to the powerful climaxes of rich
musical expression,

High-current, dynamic power supply, to
support high speed and large current flow

A loanoise Schottky barrier diode, well known
for its superior sWitching characteristics, has been
used in the rectifier circuit. The Schottky barrier
diode used in the PMAatStOAE has 1 5 times
more capacity than previous models, which pro
vides ample current capacity to accommodate one
going successions of large bursts in sound while
preserving its power and stability. Lower impede
ance has been achieved by doubling the normal
thickness of copper foil used in the power supply
circuitry, a design that adds stability to the cure
rent supply The use of custom parts for the block
capacitor, thoroughly tested for their contribution
to high sound quality. further underscores Denons
uncompromising approach to audio technology
and impeccable sound.

Direct Mechanical Ground Construction to
minimise unwanted vibration

The PMAalSTOAE features a redesigned construc7
tion that thoroughly suppresses the adverse influa
ences of vibration and electrical noise. Compared
to previous models, the Pli/lAatStOAE has a lower
centre of gravity where the power amplifier board
has been mounted closer to the bottom of the
chassis, a construction that protects the circuitry
from vibration. A tWin monaural configuration With

L/R symmetn/ has been adopted for the power
amplifier block. And since circuits with different
signal levels have been separated, they are thorn
oughly protected from mutual interference or noise.
These design improvements contribute to a highly
transparent, expressive sound.

Minimum signal paths, to protect signal purity
Signal paths have been made thoroughly simple
and straight to ensure a pure playback sound The
minimisation of signal paths prevents signal dega
radation between circuits. In the amplifier stage,
minimum signal paths reduce noise entering the
ground circuit, a fundamental component in sig
nal amplification, and stabilises ground potential
When the operating foundation of the amplifier
circuit is clear, the playback sound is also clear.

Leakage-cancelling-mounted twin transformers
Two transformers have been connected in parallel
to dramatically improve electrical and magnetic
characteristics. The Leakage Cancelling (LC) mounta
in system, a method of cancelling mutual magnetic
influences, has been used to minimise the leaking
of magnetic flux, a source of noise inside the amp.
The transformers were mounted With a plate be
tween them and the chassis, Unlike conventional
models, this plate is dualalayered. A combination
of special resins and vibrationaresistant materials
has also been used to produce a floating effect
that prevents adverse influences from affecting
sound quality.

High-grade volume control for precise quality
management

The PMAatSl OAE's volume control, an element that
significantly influences the quality of sound from an
amplifier, is the same motoradriven volume used
in the highaclass PMA72010AE. Denon engineers
carefully tested several types of volume controls
before deciding that this was the one that best
brought out the expressive power of sound in a
class of its own.

Newly-developed heat sink, to suppress vibra-
tion caused by resonance point

The PMAatSTOAE is equipped with a heat sink of
a new shape made up of 3 fins of different thicka
nesses. Since these fins use the different thicka

nesses to disperse resonance points, they prevent
vibration caused by resonance from adversely
affecting sound quality and ensure that the sound
it produces is beautifully transparent and detailed.

Wide-range playback, supporting

Super Audio CD

The PMAalSOOAE achieves an effective frequency
response of up to 100 kHz. The use of a low7
impedance volume control also suppresses noise
generated inside the amp during actual use to en
sure optimum resolution. This Widearange playback
capability is ideal for highagrade audio format such
as Super Audio CD.

Microprocessor Stop Mode,

for pure enjoyment of music

ln this mode, when no operation has occurred, the
PMA71510AE stops microprocessor operation.
This stops clock oscillation in the digital circuitry
and allows you to enioy a purer musical sound

Useful function

System remote control unit to control not only
the amplifier but also a CD player l

The supplied remote control unit not only opera
ates the PMAatStOAE but also the Denon DCDa
tSlDAE Super Audio CD player. The buttons used
most frequently have been arranged for easy op
eration when the unit is held in one hand.
