 DAC主時鐘設計
    採用DAC主時鐘設計, 使用DAC作為主時鐘
    並精確地同步數字電路, 通過將主時鐘置於
    D/A轉換器的緊鄰區域, 抑制了額外抖動的發生,
    並實現了高精度的D / A轉換
 為了最大化數字音頻電路的性能, 作為半導體操作
    標準的時鐘質量非常重要, 因此, 安裝了大大降低
    作為頻率位移的相位噪聲的時鍾振盪器,
    此外, 根據頻率(44.1kHz / 48kHz)安裝兩個時鍾振盪器,
    並通過根據聲源的採樣頻率進行切換來最小化抖動
 先進的UHC-MOS單推挽電路
    單個UHC-MOS (超高電流MOS)FET,
    從非常小的區域到大電流區域具有出色的線性度,
    並且能夠流過大電流以實現高靈敏度和高強度,
    採用了一種用於推挽的簡單電路, 為了解決由於
    器件性能變化引起的聲音混濁, 這是通過並行
    驅動大量器件獲得大電流的方法中的問題,

 強大的電源電路, 增加了變壓器磁芯的
   尺寸和容量, 並提高了穩定性
   通過增加變壓器的尺寸並顯著增加磁芯尺寸和
   容量, 提高了電源的穩定性。即使使用USB-DAC,
   它也可以提供餘量的電源
   另外, 當停止向數字輸入電路供電時,
   該餘量極大地有助於"模擬模式"中的音質改善

 Denon PMA-1700NE Integrated Amplifier
    with 140W Power per Channel
 Stereo Ultra High Current Mos Amplifier
 With ultra-high current single push-pull
    circuit power and Advanced AL32 Processing
    Plus, the Denon PMA-1700NE retains the detail 
    of the original recording. Listen to your favourite
    music digital via the three digital inputs or a
    rear USB-B input—or go analogue with MM
    or MC phono equalizer and the dedicated
    Analog Mode.
 High-power 140W integrated amplifier:
    Drive your loudspeakers with 140 watts of
    power-per-channel into 4Ω ohms. This integrated
    amplifier offers compatibility with the widest
    range of speaker types and impedances for
    operational stability.
 Advanced AL32 Processing Plus:
    Advanced AL32 Processing Plus supports
    digital audio sources up to highresolution
    of 384-kHz/32-bit. The algorithms restore
    information that was lost during the digital
    recording to ensure detailed playback.
 USB-DAC:
   PMA-1700NE provides USB-DAC function that
   supports high resolution audio signals up to
   11.2-MHz DSD and 384-kHz/32-bit PCM.
   These digital signals with suppressed jitter
    will get passed on to the high quality DAC
    for an optimal D/A conversion with
    highest precision
 High-precision electrical controls:
    The PMA-1700NE embraces electrical volume,
    balance, and tone controls while preserving the 
    analogue feeling of operation. The unique
    mechanism offers smooth, linear control.
    A Source Direct function passes by all tone
    control for purest audio.
 MM and MC phono equalizer:
    The PMA-1700NE includes a phono equalizer
    that supports input from both MM and
    MC cartridges. 
 The simple, straightforward design significantly
    improves sound qualit Optical and coaxial
    digital inputs:
 The PMA-1700NE features two optical inputs
    and one coaxial input and supports PCM
    signals up to 192kHz/24 bit.
 External pre-amp input terminals:
   "EXT/PRE" input terminals are fixed gain inputs
    that can be used for connecting an external
    pre-amp using the PMA-1700NE as a power amp.
 TV auto standby (digital input):
    The PMA-1700NE includes autosensing to
    automatically switch the unit on when it senses
    a digital audio signal from an external source
    like your TV.
 Six-block chassis configuration and direct
    mechanical ground construction:
    Constructed with 1mm-thick steel plates and
    damping feet made of ABS resin with rigid rib 
    construction, the chassis protects the signal
    circuits from external vibration and eliminates
    adverse effects of mutual interference among
    the circuits.
 Digital isolator:
    Equipped with a high-speed digital isolator,
    the PMA-1700NE eliminates adverse effects on
    sound quality caused by high-frequency noise
    from a USB-connected computer or digital inputs
 Analog mode:
    Analog Mode can be used to turn off power and
    completely stop operation of the digital input 
    circuitry, avoiding any highfrequency influence
    on the analogue section
