Advanced Ultra High Current MOS Single Push-Pull Circuit
The amplifier features Advanced UHC (Ultra High Current)-MOS
technology that utilizes a minimum number of high-current ampli-
fier elements to balance advanced speaker drive capabilities and
improved sound quality. Advanced UHC-MOS is an ideal amplifier
whose power supply performance is superior to that of bipolar
transistors and incorporates the sound quality advantages of MOS-
FETs. The Advanced UHC-MOS is provided in a single push-pull
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 mu-
sical nuances to the powerful climaxes of rich musical expression.
Advanced AL32 Processing Plus supporting 384-kHz/32-bit
PCM input
For digital input, the PMA-1600NE employs Advanced AL32 Pro-
cessing Plus, the latest version of Denon's analogue waveform
reproduction technology which utilizes unique data interpolation
algorithms and also supports high-resolution 384-kHz/32-bit PCM
signal input. These algorithms interpolate points that should exist
before and after the points in large quantities of data to achieve
a smooth waveform that is close to that of the original signal. By
carefully restoring data that was lost during digital recording, the
resulting playback sound is highly detailed, free of interference,
accurately localized, richly expressive in the lower range, and
beautifully faithful to the original sound.

USB-DAC supporting 11.2-MHz DSD and 384-kHz/32-bit PCM
The PMA-1600NE provides USB-DAC functions that support high-
resolution up to 11.2-MHz DSD and 384-kHz/32-bit PCM input
signals. DSD transmission methods support ASIO native playback
and DSD Audio over PCM Frames (DoP). Since asynchronous trans-
fer is controlled by the PMA-1600NE's master clock rather than the
clock of a computer the transfer is free of jitter. The D/A converter
used in the PMA-1600NE is the same 384-kHz/32-bit and DSD
capable top class DAC used in the DCD-1600NE to deliver a clean,
high-grade sound.
6-block chassis configuration & Direct Mechanical Ground
Construction
The PMA-1600NE's chassis is configured of six independent blocks
that house the phono equalizer and input circuitry, volume control
circuitry, USB-DAC circuitry, amplification circuitry, power section,
and the control section. The chassis constructed with 1.0mm thick
steel plates protects the signal circuits from external vibration and
eliminates the adverse effects of mutual interference among the
circuits. The power section has been positioned in the center of
the PMA-1600NE. With heat sinks on both sides, this construction
of well-balanced mass is in an ideal location to prevent unwanted
vibration from affecting sound quality. In addition, the feet sup-
porting the heavy weight of the power transformer, heat sinks, and
chassis are made of ABS resin with rigid rib construction.
System remote controller and clear view front display
The PMA-1600NE comes with a system remote control unit that
can also operate the DCD-1600NE and other Denon CD players
and network audio players. The low noise FL display on the product
front panel gives source and sample rate indication.

Digital isolator and Analog Mode
The PMA-1600NE is equipped with a high-speed digital isolator
to eliminate adverse influences on sound quality caused by high-
frequency noise from a USB-connected computer or from the
PMA-1600NE's digital inputs. Since data is transferred magneti-
cally via coils embedded in an IC chip, the input and output sides
are electrically isolated. By isolating the signal line between
digital audio circuitry and the D/A converter, adverse influences
of high-frequency noise on analogue audio circuitry after the
D/A converter are eliminated. The PMA-1600NE also adopted a
dedicated secondary winding in power transformer for the digital
circuitry to shut out noise from the power source. During ana-
logue audio playback, the Analog Mode can be used to turn off
power to the dedicated digital power source and completely stop
operation of the digital input circuitry to avoid any high frequency
influence to the analogue section. Analog Mode also turns off the
fluorescent display, allowing the PMA-1600NE to operate as a
purely analogue amp (during Analog Mode, USB-B, coaxial digital,
and optical digital inputs are disabled).
MM/MC phono equalizer
The PMA-1600NE includes a phono equalizer that supports input
from both MM and MC cartridges. This phono equalizer has high
gain, and as loops in the circuit board pattern can cause adverse
effects on sound quality, the "simple & straight" design represents
a significant improvement. On the PMA-1600NE, the MM/MC
toggle switch was changed from a push type to a relay type, which
shortens the pattern on the circuit board and makes signal loops
smaller, allowing delicate analogue signals to be amplified with
greater purity.
