MADI/AES Converter就在RME

 RME 推出 先進的MADI/AES  轉換器 

May 2, 2005

RME 將MADI系列推升至 ADI-642, an 8-channel MADI to AES的規格轉換器,除了其他應用以外,這台機器也可以成為Hammerfall DSP MADI PCI 卡的擴充介面,可達 192 kHz /24 bit的支援,具備72x72 分配矩陣,可以分派獨立的輸入頻道到每一個輸出軌道,所有的64組MADI channels以及 8組AES channels皆可自由結構組合。 

其他的特性還包括:

  • 內部支援AES Double 以及 Quad Wire
  • 內部支援MADI Double 以及 Quad Wire
  • 以上格式均可直接轉換規格 
  • 使用超過一台以上時具備自動延遲補償
  • 類比立體監聽,音質高達192 kHz
  • 詳細的MADI 以及 AES狀態顯示
  • 完全可透過MIDI遙控
  • 可以透過MADI端子傳輸Midi資料
  • SteadyClock技術提供最短的時基錯誤以及Clock的重生

這台機器可以處理64組24 bit/48kHz 或者是32組96kHz或是16組192kHz的的MADI channels訊號,所有的訊號都可以透過一條BNC或是光纖網路線傳輸,不論是哪種線材都可以傳輸超過百米,AES/EBU channels 則具備4組XLR輸入以及輸出端子。

The ADI-642 is compatible to all forms of increasing the sample rate. It supplies word clock in Single, Double and Quad Speed, distributes Double Wire 96kHz signals into the MADI data stream and to the AES ports, and even supports the double MADI sample rate (96K frame). The same applies to 192 kHz (Quad Wire, 192 kHz frame).

  

With the 72 x 72 Matrix Router, an input signal can be assigned to every output channel, both for AES and MADI. This not only allows free signal routing during format conversion, but also forwarding and routing of signals within the same format. An input signal can also be distributed to any number of outputs. With more than one ADI-642, several MADI signals can be combined (merged) to one MADI stream.

16 MIDI channels can be transferred across MADI (even with 64 audio channels). The device can be fully remote controlled and configured via MIDI, and all status displays can be queried through MIDI. Each ADI-642 can be given a separate ID, allowing separate remote controllability of various devices with only one MIDI channel.

RME's SteadyClock provides jitter reduction, allowing any clock signal to be improved and refreshed, and subsequently be used as reference clock at the word clock output. The last valid sample frequency will be retained in case of a loss of the input signal.

Automatic Delay Compensation eliminates technically inherent delays when signals are transferred from one unit to another. Each device automatically recognizes its position within the chain and ensures sample synchronized operation of all AES inputs and outputs.

The analog monitor output operates in stereo and has a low impedance. It can be used as line and headphone output and supports 192 kHz at 119 dBA SNR. The routing matrix can assign any of the 36 stereo input pairs to the monitor output.
