RMEs ADI-4 DD is a highly cost-efficient AES to ADAT and ADAT to AES converter. Support for up to 96 kHz and a built-in jitter suppression are just two of several outstanding features. 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 Professional or Consumer sub code. Channel 1/2 can optionally be received and output optically (TOSLINK).

RME's SteadyClock 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), Yama
