RME ADI-648

The MADI channels are transferred from and to 8 ADAT optical inputs and 8 outputs via TOSLINK. Furthermore, the ADI-648 contains an easy-configurable 8-Channel 16x16 Matrix Router. Any of the outputs, which are divided into 8-Channel blocks, can be fed from any 8-Channel input block, both on the ADAT and the MADI side. With this, there is not only free routing within the M-A and the A-M conversion, but also splitting and routing within the same format. An 8-Channel input block can be routed to any number of output blocks in parallel. Using more than one unit, several MADI signals can be combined to one (merging). Here are some application examples:

• Managing long distances with a single cable
• ADAT breakout box for devices with MADI interface
• Connecting MADI-based equipment to RME's Hammerfall series
• ADAT optical patchbay and router
• MADI coaxial / optical or vice-versa converter and splitter
• MADI redistributor, patchbay and router
• MADI Merger

SyncAlign SyncAlign
SyncAlign includes several methods and techniques to guarantee absolute data alignment with regard to time and channels. No RME digital audio card will ever swap channels, not in stereo nor in multi channel mode, regardless what you do with the card and the signals it gets. SyncAlign also controls the timing among the channels, no matter how much are used, they will always start sample-aligned.
When the record while play mode is activated, the corresponding software first starts record and then playback (or playback then record.) SyncAlign can compensate the time difference so that an exact simultaneous start of record and playback in the record while play mode is guaranteed. In asynchronous mode (different programs use different stereo devices of one card) this part of SyncAlign is automatically deactivated.® and SyncCheck SyncCheck
When working with several digital sources it is not only necessary that these are all properly locked, they also have to be totally synchronized. Else drop outs and crackling occurs.
RME's exclusive SyncCheck checks all input signals. In clock mode Master the synchronous operation to the internal clock is checked. This outstanding and unique technology helps to find errors immediately. The actual state of each input is displayed in the settings dialog.®, technologies known from and proven by other RME products, allow for perfect sync between all channels and easy notification of error states. And of course multiple devices can be cascaded and synchronized sample-accurate using word clock. The ADI-648 accepts 56 channels, 64 channels and 96k frame at its input, and can be set to generate those formats at its output. This way the ADI-648 even serves as perfect interface between otherwise incompatible MADI devices!

The compact device with 19" width and 1HU has numerous further outstanding features, like Intelligent Clock Control (ICC) Intelligent Clock Control (ICC)
Our unique SyncCheck and AutoSync technology has evolved into the new Intelligent Clock Control of the Hammerfall DSP system. HDSP is the only digital I/O-system worldwide capable of measuring and displaying the frequency of all clock sources. Even word clock! Based on validity and current sample rate the system then decides which clock source should be used - fully automated and performed in hardware! With this the HDSP system offers the most easiest handling of the present clocks, although having a lot digital inputs, plus the most advanced support when configuring the clock setup.  and storing of the settings. It's even possible to transmit 16 MIDI channels in parallel to all 64 audio channels. A fully automatic input selection between optical and coaxial input offers a useful redundancy mode for critical applications. Extensive status displays give information about Lock a
