PMA-700AE

■

High Current (HC) Single Push-Pull Circuit to balance details and power

The PMA-700AE's HC Single Push-Pull Circuit, for dramatically bringing out the
amplifier's best ability, inherits the same concept of the UHC Single Push-Pull
Circuit that is used in DENON's high-end integrated amplifiers and has been criti­cally acclaimed for the expressive richness of its sound. The HC transistor has
twice the capacity of conventional transistors to supply electrical current and
handle moments of peak current, ensuring rock-solid stability in musical expression.
HC single push-pull technology masterfully balances high power and the delicate
nuances of music.

■

High-speed, large-capacity power circuit

To bring out the full potential of the HC single push-pull circuit, the same Schottky
barrier diode that is renowned for its high reliability in high-end models is used for
the PMA-700AE's rectifier circuit. The large-current characteristics with minimal
noise during high-speed operation enable powerful, low-noise playback of high­quality sound. The combination of this Schottky barrier diode and a block type
capacitor for smoothing high-quality sound makes a stable power supply possible.

■

Main transformer with separate power supplies for analog and digital circuits

The coiled wire of the power transformer for the audio signal and control circuits
has been separated to eliminate mutual interference and adverse influences on
sound quality. There is also a prepared transformer that is used during remote
power-off standby to minimize power consumption during standby and improve
environmentally friendly performance.

■

Thorough design for high sound quality

The PMA-700AE employs DENON's Signal Level Divided Construction (SLDC) in
which the circuits for small and large signals, the microprocessor and other
circuits are separated in an ideal manner to minimize interference among the
circuits. In addition, a CD/PHONO input relay switch injected with an inert gas is
used to form a straight signal path and maintain signal purity. DENON has also
strictly selected parts for high-quality sound and reliable operation, such as
DENON's original block capacitor for sound smoothing, carbon resistors, capacitors
and others. The PMA-700AE has been designed for high sound quality in
extremely minute detail.

use to achieve a high resolution. These features and others give the PMA-700AE
plenty of latitude to handle the wide dynamic range of high-grade audio sources
such as Super Audio CD and DVD-Audio.

■

Microprocessor Stop Mode, for higher sound quality

The Microprocessor Stop Mode automatically stops all operations of the micro­processor when it is not needed during playback. By stopping the oscillation of
the microprocessor's clock during normal listening, the audio signal is protected
from noise and the quality of sound is improved.

■

Source Direct, for clean pure audio playback

The PMA-700AE 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.

■

PRE OUT jack, for future upgrades

The PMA-700AE is equipped with a PRE OUT jack that allows the connection of a
high-output power amplifier or subwoofer in future system upgrades.

■

REC OUT Selector

The PMA-700AE's REC OUT Selector function lets the system perform recording
operations such as from CD to MD in the background while listening to a record.

■

PHONO Equalizer Amp (MM), for connecting an analog record player

■

Total design inherited from the premium "SA" models

The PMA-700AE sports a refined design that inherits the quality of Denon's high­end models and harmonizes well with system upgrades in this series. Color can
be chosen from Premium Silver and Black.

■

Newly-designed System Remote included

The PMA-700AE's system remote unit controls the main volume, function switching,
muting, and remote power on/off (linked with three AC outlets). The system
remote also controls DENON CD players, tuners, and cassette decks.

■

Wide dynamic range playback, supporting a variety of high-grade audio

sources

The PMA-700AE's tone circuit, power amplifier circuit and other areas have been
fine-adjusted to secure a frequency response of up to 100 kHz during actual use.
Also, improvements in the volume circuit suppress noise in the amplifier during
