RME ADI648 24-Bit / 96 Kilohertz 2x64-Channel MADI to ADAT Converter

This multi-channel audio digital interface offers format conversion from MADI to ADAT and vice-versa. The ADI-648 thus combines the world‘s most successful multi-channel interface with the professionals‘ exclusive high-end interface. The MADI channels can be sent to and from 8 ADAT optical inputs and 8 outputs via TOSLINK.

Features:

• Sixty-four channel MADI/ADAT format converter
• MADI redistributor, patchbay and router
• Extensive status displays give information about Lock and Sync states and the physical quality of the incoming signal
• A fully automatic input selection between optical and coaxial input offers a useful redundancy mode for critical applications
• Supplies word clock in Single and Double Speed, distributes Double Wire 96kHz signals into the MADI data stream, is also capable of double MADI rate (96k Frame) or per Sample Split (S/MUX) to the ADAT ports
• SyncAlign and SyncCheck technologies ensure perfect synchronization and clear detection of errors
• Multiple units can be stacked and operated sample-aligned, using word clock.
• All settings are stored when the unit is switched off
• Sixteen MIDI channels can be transferred across MADI even with 64 audio channels
• The device can be fully remote controlled and configured via MIDI and all status displays can be queried through MIDI
• Each unit in a multiple-unit setup can be given a separate ID, allowing separate remote control of the devices utilizing only a single MIDI channel
