This
unit is the successor model of SACD player, "DCD-1650SE" that released in 2009.
Since
1650 series appearances in 2000, it becomes "the ninth generation"
model.
"Advanced
ALPHA Processing" technology,
realized the high-bit and high sampling by
proprietary data complement algorithm.
Improved significantly the amount of
information on the time axis by the high-speed signal detection and processing
techniques.
By
performing up-convert process 16 fold by this technology,
without losing the
texture of the original data,
high-frequency signal with a frequency of 20kHz
or more that was cut by sampling 44.1kHz, such as CD, also significantly
increases the amount of information,
precisely to a high frequency to realize
the natural interpolation.
Further, switching to optimum filter characteristics
to match the waveform of the signal to reproduce the digital filter,
"adaptive digital filter" is adopted to achieve a more natural signal
reproduction.
In Drive,
adopted "SVH (Suppress Vibration Hibrid) mechanism"
loader of hybrid
structure that combines the Denon original, different materials.
To suppress
vibration when disk is rotated at high speed ,
disposed the drive motor close
to turntable.
To design very short length of the motor shaft
and to adopt a
brushless motor with high life to be unaffected by high-speed rotation.
For
vibration-proof structure of the whole, adopted "Direct Mechanical
Ground" structure.
To mechanical case made of iron to prevent resonance,
the vibration-proof structure 3 layer bottom plate, two layers of top plate, to
ensure high rigidity.
Side panels in two-layer structure,
thereby suppressing
the resonance by the combination of different materials.
Tray, aluminum
die-cast. In drive mechanism,
laid the center of gravity by mounting the center
of the body
to optimize the weight balance of the entire equipment.
