RME ADI-4 DD 8-Channel 24-Bit/96kHz AES/ADAT Format Converter

The RME ADI-4 DD is a digital audio format convertor that converts 8 channels of AES to ADAT and 8 channels of ADAT to AES. The RME ADI-4 DD will operate at 24-bit, and sample rates of up to 96kHz. RME have incorporated their outstanding SteadyClock technology, and the internal jitter suppression make the RME ADI-4 DD a rest easy choice for those needing a high-end digital audio format conversion solution.


      The device basically consists of two converters: four AES-3 inputs to double ADAT outputs, and double ADAT inputs to four AES-3 outputs. The double ADAT ports enable full 8 channel support, from 32 kHz up to 96 kHz (S/MUX). The unit provides one XLR I/O directly. A DB-25 connector allows for a use of industry standard AES-3 I/O breakout cables. Setting an internal connector easily changes the DB-25 connector to meet the pinout of Tascam (Digidesign), Yamaha and Euphonix cables.

      Application examples:
      AES/EBU frontend for RME's digital I/O cards (ADAT optical I/O)
      Serves as 8-Channel AES and ADAT I/O for all digital mixing desks with ADAT or AES ports
      Allows to operate up to 4 SPDIF or AES devices
      Converts between AES-3, SPDIF and SPDIF optical
      Removes jitter from AES-3 and ADAT signals

      Conversion modes (selection):
      8-Channel AES to ADAT optical converter (96 kHz)
      2-Channel AES to 8-Channel ADAT splitter (96 kHz)
      8-Channel ADAT to AES converter (96 kHz)
      2-Channel AES to 8-Channel AES splitter (96 kHz)
      4-Channel AES Double Wire to AES Single Wire converter (96 kHz)
      4-Channel AES Single Wire to AES Double Wire converter (96 kHz)

      All in all the ADI-4 DD shows an unsurpassed flexibility together with a sensational price point. It is a perfect interface solution in all areas, from home user up to broadcast applications.
