PMA-510AE

Integrated Amplier

Integrated amplier with enhanced audio dynamics

The PMA-510AE features High-Current Single-Push-Pull circuitry to achieve both strength and detail in music
playback, which is DENON's focus for its pure audio ampliers. DENON's engineers have used their extensive
knowledge of audio technology to create an integrated amplifier that is a step up in class from previous

designs. For improved convenience, the remote control unit that comes with the PMA-510AE includes the
main functions that control DENON CD players.

High quality sound

High Current (HC) Single-Push-Pull Circuit for
musical detail and power

The PMA-510AE incorporates HC transistors with

2 to 3 times the electrical current supply capability
of conventional power transistors for audio.

DENON’s acclaimed HC Single-Push-Pull Circuit
has been inherited from its high-end models which,

together with a fully discrete ampli er design, pro­duces a powerful sound  lled with beautiful musical
details.

High-speed, high-capacity power supply
circuit for HC Single-Push-Pull

The PM A-510 AE’s powe r circuit us es a block

capacitor that DENON engineers have jointly de-

veloped with a parts manufacturer and a Schottky­barrier diode that features low internal resistance
for low loss, short recovery time, and negligible

rectifying noise. This highly stable electrical current
supply further brings out the expressive power of
sound produced by the HC Single-Push-Pull Circuit.

Wide dynamic range, supporting high-grade
audio sources

The PMA-510AE’s tone control and power ampli-

 er circuit have been carefully adjusted to secure a
frequency response of up to 100 kHz during actual
use. Also, improvements in the volume circuit sup­press noise in the ampli er to achieve high sonic
res olu tion. The se feature s and other s give the

PMA-510AE plenty of latitude to handle the wide
dynamic range of high-grade audio sources such

as Super Audio CD and DVD-Audio.

Main transformer with separate power supplies
for analogue

The coiled wire within the power transformer for
the audio sig nal an d control circuits has been
separated to eliminate mutual interference and ad-

verse infl uences on sound quality. The PMA-510AE
also has a separate transformer to minimize power
consumption when in "standby". Ensuring a more
environmentally friendly design.

Micro-processor stop mode, for higher sound
quality

The Mic ro- processor Stop Mode automatically
stops all operations of the micro-processor when

it is not needed during playback. By stopping the

oscillation of the micro-processor’s clock during
normal listening, the audio signal is protected from

noise and the quality of sound is improved.

Vibration-resistant design with
Direct Mechanical Ground Construction

The power transformers, themselves a source of
vibration, have been placed near the base of the
unit and immediately above the insulators to allow
direct dissipation of unwanted vibrations, mini-

mizing propagation through the unit.

Signal Level Divided Construction

The PMA-510AE employs DENON’s Signal Level
Divided Construction (SLDC) in which the circuits

for small and large signals, the micro-processor,
and other circuits are separated in an ideal manner

to minimize mutual interference.

"Source Direct" function – for clean, pure audio
reproduction (simple & straight signal)

The PMA-510AE includes a Source Direct function
that allows the audio signal to bypass the Bass,

Treble, Loudness, and Balance control circuits and

maintain its purity for optimum sound transparency

during playback. This Source Direct function works
for all inputs.

Every detail of the design devoted to
high-quality sound

The relay switch used for CD and Phono input con­tains an inert gas to prevent the occurrence of noise

that can negatively affect the signal. In addition,

durable parts strictly selected for their contribution

to sound quality, such as the large-capacity block
capacitor for the power supply circuit, high-quality
sound carbon resistors, and high-quality sound
capacitors, are also used. Eac h indiv idual part

employed in configuring the circuits reflects this

emphasis on high sound quality.

Useful Features

Newly-designed remote control unit

The PMA-510AE’s remote controls the main vol­ume, fu nc tion sw it ching, mu ti ng, and rem ote

power on/off (linked with an AC outlet). The sys-

tem remote also controls DENON CD players and

tuners.
