再來打開N10的內部
N10為線性電源,可看到3顆藍色的變壓器,分別供不同線路使用
鋼鐵人下方就是數位處理線路,特別做了單獨的保護隔離處理
將隔離的上蓋打開,就可看到N10的數位處理中心
其採用Field-Programmable Gate Arrays (FPGA)架構及OCXO恆溫控制石英振盪器
FPGA-based All Digital Phase-Locked Loop System
An All Digital Phase-Locked Loop system (ADPLL) incorporating Field-Programmable Gate Arrays (FPGA) with OCXO clocks precisely times digital audio data transmissions and minimizes jitter to below negligible levels
Oven-Controlled Crystal Oscillator (OCXO) for long term jitter reduction
OCXOs are among the most accurate and stable clocks in use today. OCXOs are orders of magnitude more accurate and stable than commonly used ordinary crystal oscillators usually found in computers. Temperature changes cause crystal oscillations to fluctuate, which can lead to jitter in the digital audio signal. Moreover, ordinary crystals are much less stable and lose accuracy over time. In OCXO clocks, a very stable high grade crystal oscillator is enclosed in a compartment and kept at a constant temperature to prevent jitter from temperature fluctuations.
SPARTAN與XMOS晶片
OCXO恆溫控制石英振盪器
2顆2TB 2.5″的硬碟及一顆240GB的SSD固態硬碟,做了很穩固的金屬支架以控制減少運作的震動
在自家的設計的主機版上有著一個非常大的金屬散熱磚,將其取下就可看到主機板與CPU、記憶體等
記憶體,也是筆電用的規格,容量為4GB
專為音樂設計的USB Audio Class 2.0輸出,採用極低噪的電源供應,其還可透過APP將USB的電源部份給關掉,讓訊號的傳輸更為純淨,但這要看USB DAC是否支援這樣的作法,旁邊看起來是一顆電池,在之前的aurender其他器材上也有看到,猜想應該是用來提供 USB純淨的供電之用 (也有可能是主機板所需要的電源)
Dedicated USB Audio Class 2.0 Output with Ultra Low Noise Power Circuitry
The dedicated USB Audio Class 2.0 output is designed to deliver an exceptionally transparent audio signal free of noise, and is shielded from outside electronic interference. When not in use, the power to the USB Audio output can be shut off depending on the USB DAC’s requirement.
