數位流母帶音樂播放中心 HDM-03S

HDM-03S 是集數碼母帶播放,網路存儲,控制,D/A轉換,數位錄音為一體的新一代數位音樂播放中心。

數位流母帶網路音樂播放中心HDM-03S採用了目前高性能多媒體嵌入式處理器CPU,以及多媒體DSP晶片方案技術,結合工業級的數位鎖相環(DPLL)的參考時鐘系統,有效地降低數位音頻信號傳輸的時基誤差,因而能夠達到超低的Jitter指標,並且音頻編解碼的軟體經過特別優化,能夠高速處理大碼率的24Bit / 192KHz數字母帶音頻流,可以支援所有的數位音樂格式。由於數字母帶的資料量比傳統CD的資料量大5-8倍,音樂CD光碟 (16Bit / 44.1Khz)通常只能存儲一首數字母帶的檔,因此數字母帶無論是在聲場,密度,動態和解析力等都超越了傳統CD的音質。

數位音頻信號到類比轉換的D/A解碼處理部分採用英國Wolfson公司的旗艦級帶數位濾波器的WM8741解碼晶片,該晶片是目前聽感最好的D/A晶片,可生成比過去傳統的數位類比轉換器更加自然的“類比感覺”聲音。同時參考電路得到了英國Wolfson原廠工程師的優化並校聲處理,以及Wolfson原廠的測試,整機在硬碟播放狀態的信噪比達到了120dB (單聲道),因此為數位音頻的重放提供了非常高品質的保證。


本機不僅僅是一台數字母帶播放器,當在主功能表上選擇DAC時就是一台高性能的D/A轉換器了,最高可以支援到24Bit/192KHz的格式,可以支援同軸和光纖的輸入,通過同軸和光纖的輸入可以把CD的音樂檔直接以WAV的格式保存到內置的硬碟堶情C


本機還可以單獨作為網路音樂伺服中心,由於本機器支援至500GB的大容量外置SATA硬碟,不僅具有強大的網路功能,還可以連接網路硬碟NAS,以及通過WI-FI / LAN來共用 / 播放網路上其他電腦的各種資源。另外,還可以做網路收音機使用,內置的電台列表能夠收聽到全球約1萬多個數位網路電台,可以想像,當身處在國內便可以直接收聽到歐美或者全球各地即時的音樂節目是多麼愜意的一件事情。

當作為網路音樂伺服中心時,WI-FI / LAN的網路系統設置亦十分簡單,對於沒有網路技術經驗的用戶來說系統在默認狀態時,可以自動連接到網路,不需要做任何設置,對於有經驗的用戶,亦可以採用手動的方式來修改設置。


產品特色:

本機無論從電路設計上:數位部分採用三級多組高性能的線性電源結構,分別給CPU電路,時鐘電路,硬碟和USB等供電,類比部分採用高速運算有源伺服的超級甲類並聯電路,這樣電源可以達到超低的內阻給運算電路供電,帶來的好處就是聲音更加溫暖和厚實。


在材料選擇上:採用四層加厚的鍍金PCB電路板,整機的電容採用全固態的Low ESR電容等Hi-END的發燒零件。

A Multifunctional Digital Stream Master with Music Playing, Local Storage, Network Access, D/A Conversion and Digital Music Recording integrated all together.

The HD Music Center HDM-03 adopts the specialized 32-bit high-performance multimedia processor and DSP solution. The reference clock system is the industrial-class digital phase-locked loop (DPLL) system, which effectively reduces clock jitter in transmission of digital audio signals and achieves an ultra-low Jitter. In addition, by proprietary technology the audio coding and decoding software can process 24Bit/192KHz high bit rate digital master tape audio stream at a high speed and support the decoding of all kinds of digital audio formats (WAV//WMA/ APE/FLAC/ALAC/ACC). In the future, through firmware upgrading, the device can support more audio formats.

The audio D/A decoding part adopt the flagship-level decoding chip - WM8741 with digital filter from Wolfson of the UK. Known as a D/A chip with the best hearing impression, this chip can produce “simulated feel” sounds more natural than those produced with traditional digital simulated converters. What is more, the reference circuit has been specially optimized and calibrated by engineers from the plant of Wolfson, as well as passing the factory test made by Wolfson. As a result it can provide SNR of 128dB (monophony) which guarantees a high quality of digital audio rendering. Besides, for the reason that standalone CPU is put to control the D/A decoding chip, this device can also be used as a high-performance independent D/A converter (24Bit/192KHz).

Features:

  • Support decoding of all kinds of main stream digital audio formats, including WAV, WMA, APE and FLAC etc.
  • Support the playing of high bit rate digital audio format (up to 24Bit/192K) and studio master tape format.
  • Support the playing of audio formats, including APE and FLAC, and CUE relevant files.
  • Flagship-level D/A decoding chip - WM8741x2 and digital filter from Wolfson of the UK (passing the factory test made by Wolfson).
  • Support S/PDIF digital audio input and can be used as an independent decoder (Support 24bit/192kHz format).
  • Support digital music recording by S/PDIF signal input. The sound can be recorded as CD tracks or other S/PDIF signals and saved as 24bit/96KHz WAV files in the external hard disk or USB storage.
  • Support RCA analog audio output and digital volume control functions.
  • Industrial level digital phase-locked loop (DPLL) system reference clock system, effectively reducing clock jitter in transmission of digital audio signals with an ultra-low Jitter index about 100PS.
  • High-performance linear power supply system with independent power supplies for digital/analog parts. Precise linear secondary stable-voltage power supply is adopted for the digital part while Class A high-speed active parallel servo power supply is adopted for the analog part, to achieve an ultra-low internal resistance of the power source.
  • Adopting Hi-END Hi-Fi parts such as all-solid-state Low ESR capacitor.
  • S/PDIF digital audio output port (for digital CD output).
