Powerful yet Sensitive, the Newly-developed Large-capacity Block Capacitor
Provides Greater Support for the Outstanding Expressive Power of
UHC-MOS. The PMA-2000 IV R is loaded with an UHC-MOS single push-pull
circuit, leakage canceling (LC) mounted twin transformers, and
highly rigid chassis divided into 6 separate blocks, and features
a newly-developed large-capacity block capacitor in the power section.
This new feature provides greater support for the outstanding expressive
power of UHC-MOS and produces a more spacious, dynamic sound from
high-quality digital sources such as DVD-Audio and SACD. The PMA-2000
IV R is also equipped with a power amp direct input terminal that
lets you use the PMA-2000 IV R as a stereo power amp. You can also harness
the superior performance of the PMA-2000 IV R for use as a power
amp for multi-channel output.
Delicate details on a powerful foundation ::
The hallmark of UHC-MOS single push-pull technology. The ultra-high-current
(UHC) MOS was developed and subsequently praised for its ability
to drive speakers while preserving the delicate details of high-quality
music recordings. This amplification device is capable of delivering
peak current as much as 3 to 10 times greater than that of conventional
MOS-FET devices, resulting in a successful balance between power
to drive the speakers and ability to maintain the integrity of
delicate musical nuances. From the timbre created by a violin soloist
who gently lifts the bow from the strings in a quiet final moment
to the grandiose strength of a full orchestra playing in fortissimo,
the UHC-MOS single push-pull circuit ensures you will hear all
the breadth and details of this sound.
Leakage Canceling (LC) Mounted Twin Transformers for Wide Dynamic
Range and Low Noise By employing a large magnetic circuit with low
magnetic flux density, the power transformer achieves superior response
characteristics capable of accommodating musical signals with a broad
dynamic range even in areas of magnetic saturation. The LC mount,
which serves to eliminate mutual interference caused by magnetic
fields and other factors, significantly reduces leakage flux which
is a source of noise inside the amp. The result is a powerful speaker
drive that ensures both remarkably transparent speaker output and
low noise. The voltage amplification stage and the coiled wiring of the
phono equalizer power supply have also been separated, and the transformer
for the control circuit that controls signal relays and other functions
have been separated as well, to thoroughly eliminate mutual interference
between the circuits.
Powerful high-current
dynamic power circuit with newly-developed large-capacity block capacitor
for audio ::
High-current Schottky barrier diodes in the rectifier
circuit have been selected for their low-noise characteristics and
high-speed response to provide high-power support for the expressive
power of the UHC-MOS circuit. The combination of Denon's newly-developed
large-capacity block-type electrolytic capacitor for audio in the
power section and the UHC single push-pull circuit supplies plenty
of clean current required by the speakers for the entire audible
frequency range.
Chassis
divided into 6 blocks ::
The power amp block in the PMA-2000 IV R has been designed in a
twin monaural configuration separating the left and right channels
to ensure high sound quality free of external noise and mutual
interference among circuits. To provide thorough shielding at the
signal level, steel plates of 1.6 mm thickness coated in black
have been used to divide the chassis into 6 blocks, a design that
preserves sound quality by preventing interference among the blocks
and faithfully reproduces the sonic ambience of the original recording.
Wide-Range Play Capability for
DVD-Audio or SACD ::
The power amp circuits of the PMA-2000 IV R have been meticulously
designed to reproduce the exceptionally high sound quality with
wide frequency response from 10 Hz to 100 kHz in advanced, high-quality
digital sources such as DVD-Audio and SACD.
Power Amp Direct Input ::
The PMA-2000 IV R provides a power amp direct input that lets you
use its superior amplifier performance as a power amp for multi-channel
output. The power amp direct input can be used when you set the
switch on the rear panel to ON, and multi-channel output is possible
when you switch the Input Selector on the front panel to AUX-2/Amp
Direct. Since the PMA-2000 IV R operates as an integrated amp in
the other positions, you can easily decide whether you want to
use the PMA-2000 IV R as a multi-channel power amp or an integrated
amp. Denon engineers have also devoted considerable attention to
preserving sound quality in these instances by selecting the best
quality relays and other parts.
PRE OUT terminal ::
The PMA-2000 IV R's PRE OUT terminal lets you connect a subwoofer
to your system. Thorough attention to sound quality is again
in evidence here in that PRE OUT output occurs through a discrete-configured
MOS-FET flat amp inherited from Denon's high-end PRA-S1 pre-amp.
Precision
Mechanical Ground Construction, to Thoroughly Suppress Vibration ::
Radiator stabilizers and radiators dampened with elastic rubber
have been mounted directly near feet endowed with high vibration
absorption characteristics, in order to minimize the effects of
vibration from the power transformer and other sources. The top
cover is also impervious to vibration, as is the volume knob which can easily
transmit vibration to the signal as well. The PMA-2000 IV R ensures that
vibration is thoroughly absorbed in all possible areas so that it can deliver
consistently high sound quality.
Precision Signal Ground Circuit, to Preserve
Signal Purity ::
In the PMA-2000 IV R, the adverse effects of noise from the constant
current circuit and other sources onto the signal as it passes
through the power amp stage are minimized by the careful placement
of ground points for each circuit. The signal is thus amplified under ideal
conditions to produce an eminently clean, transparent sound.
Large, Gold-Plated Speaker Terminals ::
Supporting Bi-Wiring The speaker terminals on the PMA-2000 IV R
feature gold plating on precut brass to minimize signal transfer
loss. The hole diameter of the clamp section is a generous 6 mm, allowing
sufficient room to connect even super-thick speaker cables. Two sets of
terminals have been provided, and bi-wiring is also supported.
High-Performance
Phono Equalizer ::
The PMA-2000 IV R includes a high-performance Phono equalizer that
employs a first-stage circuit in a discrete configuration with
low-noise FETs. This equalizer allows lovers of analog music sources to
enjoy high-quality playback via a dedicated stable power supply. A simple
switch selection permits use of a MM or MC cartridge.
