Spletna stran proizvajalca RMERME's ADI-4 DD is a simplified and highly cost-efficient smaller version of the renowned ADI-8 DD. Built into a space-saving half-rack space enclosure, the ADI-4 DD includes all of the advanced technology of the ADI-8 DD, except for sample rate conversion and TDIF ports. 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 RME's 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 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.
