L’ADI-4 DD de RME est un convertisseur AES vers ADAT et ADAT vers AES, d’un très bon rapport qualité/prix.
L’appareil se compose de deux convertisseurs : quatre entrées AES/EBU pour doubler les sorties ADAT, et deux entrées ADAT pour 4 sorties AES/EBU. Le double port ADAT permet de supporter les 8 canaux, de 32 kHz jusqu’à 96 kHz (SMUX). L’appareil possède une entrée/ sortie directement en XLR. Un connecteur D-Sub à 25 broches permet d’utiliser les câbles standards épanouis d’entrées/sorties en AES/EBU.
Il est possible et facile de changer un connecteur D-Sub 25 broches pour correspondre au brochage des câbles Tascam (Digidesign), Yamaha et Euphonix. Le signal de sortie AES est commutable en mode professionnel ou grand public. Le canal 1/2 dispose également d’une entrée/sortie optique (TOSLINK).

Points forts

  • Entrées AES/EBU : 1 x XLR, 4 x via connecteur DB-25, compatibles SPDIF
  • Sorties AES/EBU : 1 x XLR, 4 x via connecteur DB-25, symétriques
  • Optique SPDIF: le 2ème ADAT se commute en mode entrée/sortie SPDIF
  • Entrées ADAT optiques : 2 x TOSLINK, 24-Bit, Bitclock PLL
  • Sorties ADAT optique : 2 x TOSLINK, 24-Bit
  • Entrée/Sortie Word Clock sur connecteur BNC
  • Sources de synchronisation : ADAT optique, AES/EBU et Word Clock

The actual states of incoming and outgoing signals and ongoing operations within the unit are displayed by LEDs in an easily overseeable way. SyncCheck ® , already found in other RME products, not only shows if an input signal is locked, but also if multiple inputs are in synchronicity. Furthermore RMEs SyncAlign ® technology prevents accidental errors of ± 1 sample misalignment between the AES/EBU inputs. The AES output signal can be set to Professsional or Consumer subcode. Channel 1/2 can optionally be received and output optically (TOSLINK).

RME's SteadyClock(TM) technology guarantees an excellent performance in all clock modes. Its highly efficient jitter suppression enables the ADI-4 DD to refresh and clean up any clock signal, and to provide the clock signal as reference clock at the word clock output. Additionally, Intelligent Clock Control (ICC) will maintain the last sample rate detected as valid in case of fault and loss of input signal. The device can be stacked without limit, all devices will be sample synchronous by using word clock. All settings are stored at power-off.


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.
