6-block chassis configuration & direct Mechanical Ground Construction

6区间底盘结构和直接机械接地构造

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 supporting the heavy weight of the power transformer, heat sinks, and chassis are made of ABS resin with rigid rib construction.

PMA-1600NE的底盘配置为六个独立的区间，包含唱头均衡器和输入电路、音量控制电路、USB-DAC电路、放大电路、电源部分和控制部分。底盘结构为1.0mm厚的钢板，保护信号电路免受外部振动，并能消除电路之间相互干扰的负面影响。电源部分位于PMA-1600NE的中心。两侧都有散热器，这一具有良好质量平衡的结构处于理想的位置，能避免意外振动影响音质。此外，支撑电源变压器、散热器和底盘的支脚由ABS树脂制成，且带有刚性肋条结构。

Advanced AL32 Processing Plus Supporting 384-kHz/32-bit PCM input

Advanced AL32 Processing Plus支持384-kHz/32位PCM输入

For digital input, the PMA-1600NE employs Advanced AL32 Processing 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.

对于数字输入，PMA-1600NE采用Advanced AL32 Processing Plus，这是最新版本的Denon模拟波形再现技术，它使用独特的数据内插算法，并且还支持高解析度384-kHz/32位PCM信号输入。

这些算法能插补应存在于大量数据中各点前后的点，以实现最接近于原始信号的平滑波形。通过精心恢复数码录制期间丢失的数据，致使播放的声音高度精细、没有干扰、定位精准、在更低范围表现丰富，尽善尽美地忠实于原始声音。

Digital isolator and Analog Mode

数字隔离器和模拟模式

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 magnetically 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 analogue 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).

PMA-1600NE配备高速数字隔离器，能消除来自通过USB连接的计算机或来自PMA-1600NE的数字输入的高频噪音对音质造成的负面影响。由于数据是通过IC芯片中内嵌的线圈进行磁性传送的，所以输入和输出侧均为电子隔离。通过隔离数字音频电路和D/A转换器之间的信号线路，可消除高频噪音对D/A转换器之后模拟音频电路的负面影响。PMA-1600NE还为数字电路在电源变压器中采用专用二次绕组，以剔除来自电源的噪音。模拟音频播放期间，可以使用模拟模式关闭专用数字电源的电源并完全停止数字输入电路的操作，以避免模拟部分受到任何高频影响。模拟模式还会关闭荧光显示屏，允许PMA-1600NE作为纯粹的模拟放大器工作（模拟模式期间，禁用USB-B、同轴数字和光纤数字输入）。

USB-DAC supporting 11.2-MHz DSD and 384-kHz/32-bit PCM

支持11.2-MHz DSD和384-kHz/32 位PCM的USB-DAC

The PMA-1600NE provides USB-DAC functions that support high-resolution 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 transfer 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.

PMA-1600NE提供USB-DAC功能，支持高解析度11.2-MHz DSD和384-kHz/32位PCM输入信号。DSD传输方法支持ASIO原生播放和通过PCM框架传输DSD音频(DoP)。由于异步传送由PMA-1600NE的主时钟而非计算机的时钟控制，所以传送没有抖动。PMA-1600NE所使用的D/A转换器与DCD-1600NE所使用的相同，即384-kHz/32位且具备DSD能力的顶级DAC，以提供清晰的、高品味声音。

MM/MC phono equalizer

MM/MC唱头均衡器

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.

PMA-1600NE附带唱头均衡器，支持来自MM和MC唱头的输入。本唱头均衡器均有高增益，因为电路板结构的回路会对音质造成负面影响，所以“简单而直接”的设计表现了重大的改进。在PMA-1600NE上，MM/MC切换开关从手推式改为继电器式，缩短了电路板上的结构并使信号回路更小，能以对精妙的模拟信号进行更纯净的放大。

System remote controller and clear view front display

系统遥控器和清晰的前显示屏

The PMA-1600NE comes with a system remote control unit that can also operate the DCD-1600NE and other Denon CD players. The low noise FL display on the product front panel gives source and sample rate indication.

PMA-1600NE附带系统遥控器，还可以操作DCD-1600NE和其他Denon CD播放机。产品前面板上的低噪音FL显示屏提供音源和采样率指示。

【評測】Denon DCD-1600NE + PMA-1600NE：抵玩中價 CD、擴音連 USB 解碼組合

2017年03月22日

Denon DCD-1600NE CD 機和 PMA-1600NE 兩聲道擴音機，是早前推出的高階「套裝」DCD-2500NE 和 PMA-2500NE 的低一級兄弟機。比起後者一半多少少的價錢，但就擁有大部分的功能，對於入門或者中階用家來說更加抵玩，今次就試下這套組合的表現，亦會睇下同大哥爭幾遠。

•  Chris

配備 32bit/192kHz DAC、支援 SACD 播放

DCD-1600NE 同樣也是 SACD 機，支援 CD 及 SACD 播放，另外亦可以播放燒錄在 DVD 上的 DSD（2.8MHz/5.6 MHz）以及 24bit/192kHz 的 FLAC、WAV 檔案。自家的 S.V.H（Suppress Vibration Hybrid）讀碟機設計，配合全新的拾音、解碼電路，令音樂播放更加精準、雜訊更少。新機當然都配備了 Denon 有名的 Advanced AL32 Processing Plus 技術，令音樂波形重現更順滑準確，加上 32bit/192kHz Ultra Precision DAC、DAC Master Clock 電路，可減少 jitter 的出現。而數碼、模擬電路分離的設計，就有助進一步避免音訊干擾

機身設有實體按鈕控制播歌，銀色金屬面質感一流，同 DCD-2500NE 如出一轍。

支援 Pure Direct 模式，關閉非必要電路，令音訊輸出更純淨。

DCD-1600NE 機背。

除了 RCA 輸出，光纖、同軸都有齊，另有紅外線遙控的輸入及輸出。

支援 32bit/384kHz USB 解碼、每聲道 140W 輸出

PMA-1600NE 同大哥 PMA-2500NE 一樣可作為 USB DAC，而且規格同樣強功，支援 32bit/384kHz 以及 11.2MHz DSD 解碼，應該兼容到現時絕大部分的數碼音樂檔案播放。不過輸出方面比起後者就低少少，每聲道為 140W。配備了 Advanced Ultra High Current（UHC）MOS 技術，可以兼顧到大功率輸出以及音樂細節，同時亦支援 Advanced AL32 Processing Plus 技術。機身採用特別設計，輸入、音量調節、USB DAC 電路等 6 個部分完全獨立，加上數碼、模擬電路獨立供電設計，將干擾大大降低。

前面板設有獨立的高、低音、左右聲道調節旋鈕，亦支援 Analog mode 及 Source Direct 模式。

設有小型屏幕顯示訊源、設定等資訊，支援作為 USB DAC。

PMA-1600NE 機背。

設有 A、B 喇叭輸出，支援 Bi-wiring 接駁，每聲道輸出為 140W。

USB Type-B、光纖、同軸、RCA 輸入有齊，另外亦支援 Phono MM/MC 放大。

CD 機同擴音機都採用同一款遙控器，只需要選擇好遙控模式就可以分別控制兩部機。

音質表現：細節豐富、控制力只比高階組合稍弱

今次除了播 SACD 之外，由於 PMA-1600NE 都支援 USB DAC 功能，所以亦會試下駁電腦、聽下播放 Hi-Res 音樂的表現。既播到 CD、SACD，駁電腦亦可以播埋數碼檔案，所以擴音輸出，加對喇叭就已經是一套完整系統。

測試器材：

• CD 機：DCD-1600NE
• 擴音機 / USB DAC：PMA-1600NE
• 喇叭：B&W CM6 S2

雖然輸出比起大哥 PMA-2500NE 細些少，不過實際開聲唔太覺，試音室大約 200 呎空間只需一半音量左右就完全足夠。分析力表現有少少喜出望外，聽藤田惠美《Best Audio》SACD 人聲細節豐富，呼吸、唇齒聲到弦樂的尾音、鋼琴質感都呈現得相當細緻。

藤田惠美《Best Audio》SACD

《你的名字》原聲@24bit/48kHz FLAC

單就分析力來說，同高一級的 2500 組合相差不遠，不過動態同控制力就可以感受到有分別。聽《你的名字》原聲入面〈夢燈籠〉、〈前前前世〉等幾首 Pop Rock 歌曲時，雖然節奏有力、低頻夠豐富，不過聲音動態同控制力就稍有不及，未能將鼓聲、人聲的厚度、弦樂的那種綿密質感完全呈現。聲底偏厚暖，結像幾清晰，音樂感算強，聽一些小品音樂、純人聲歌曲固然不錯，播放交響樂、管弦樂等「大場面」作品亦幾有睇頭。

總結：兩萬有找高質 CD、解碼連擴音套裝

Denon DCD-1600NE + PMA-1600NE 的分析力相當不錯，聲底厚暖、低頻豐富而且音樂感幾強。特別當聆聽空間不太大的時候，同更高階的 2500 系列相比差別無想像中大，但售價就平接近一半，對入門或者中階用家來說就更加抵玩。
