最強的多軌數位192kHz,DD轉換器

The ADI-192 DD 源自於RME的成功機種ADI-8 DD. 重新設計過的這台旗鑑具備強大的格式以及取樣頻率轉換. 具備以下新的功能:

  • 支援在ADAT, TDIF 以及 AES下192 kHz的傳輸
  • 8-詭的取樣頻率轉換,可達192 kHz
  • 取樣頻率轉換可以在AES, TDIF 或是 ADAT之間傳輸
  • 8鬼取樣頻率轉換無相位錯誤(sub-sample synchronous)
  • SteadyClock提供最小的時基錯誤以及同步Clock的重新產生
  • 完整的三重格式轉換AES/TDIF/ADAT,並且增加 SPDIF TOSLINK I/O的轉換
  • 直接支援Double 以及 Quad Wire, S/MUX 以及 S/MUX4
  • Also when using SRC
  • 特別具備TDIF word clock輸出
  • 簡單容易使用的介面

TOUR DE ADI

這台機器包含3組 8-channel 24bit格式轉換,三種輸出規格ADATTDIF and AES 可以獨立的傳送至三塚不同的輸入格式 ADAT,TDIF and AES。 輸入的訊號可以烤貝並分配至所有的輸出,四組XLR AES/EBU ,兩組ADAT 以及 TDIF 的輸入/輸出端子都容許 96 kHz / 24 bit的格式傳輸. 在192 kHz模式下, 8軌AES可以傳輸至4軌的ADAT/TDIF, 可切換的 24/192 kHz 取樣頻率轉換 容許8軌取樣頻率轉換以及 同步clock最高品質的去偶合。

由於其無輸入限制的選擇,他並不是只能做相同格式的輸出,舉例來說他可以當成四組AES/EBU取樣頻率轉換來使用。

應用方面:

  • AES/EBU frontend for RME's digital I/O-cards (with ADAT optical I/O)
  • TDIF frontend for RME's digital I/O-cards (with ADAT optical I/O)
  • AES and ADAT frontend for DTRS machines
  • 8-channel AES, TDIF and ADAT input and output for digital mixers with ADAT/TDIF port
  • Operation of four SPDIF or AES devices with different sample rates in any digital audio network
  • Converts Double and Quad Wire to Single Wire and vice versa, even with simultaneous sample rate conversion

48 LEDs clearly display the current status of the incoming and outgoing signals and the processing performed within the unit. The SyncCheck technology known from other RME devices indicates whether the input signal is locked and whether all inputs are sychronized. The AES output signal can be given a consumer or professional status. The first AES output (channels 1/2) is also available as optical TOSLINK.

Professionals will love the fact that the ADI-192 DD supports Double WireQuad WireS/MUX and S/MUX4, making it compatible to all methods of increasing sample rates by sample multiplexing on all platforms. The unit can also convert between these formats, even along with SRC. If more than 8 channels are required, several units can be cascaded and synchronized sample-accurately by word clock.

The ADI-192 DD also features an automatic distribution mode. If only one of the four AES inputs is used, the device will copy these two channels to the other three AES outputs.

RME's SteadyClock™ guarantees excellent clock quality in every situation. Due to the highly efficient jitter reduction, any clock signal can be improved and refreshed, and subsequently be used as reference clock at the word clock output. Intelligent Clock Control (ICC) will retain the last valid sample frequency in case of a loss of the input signal. All settings are retained when the device is switched off.

CONCLUSION
The ADI-192 DD is the all-in-one solution for every application of format and sample rate conversion, from 2 to 8 channels. Its flexibility is unsurpassed and the price/performance ratio is simply sensational.
