The MADI channels are transferred fromto 8 ADAT optical inputs
and 8 outputs via TOSLINK. Furthermore, RME 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 ADATthe MADI side. With this, there is
not only free routing within the M-Athe A-M conversion, but also
splittingrouting within the same format. An 8-channel input block
can be routed to any number of output blocks in parallel. 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 patchbayrouter
- MADI coaxial / opticalvice-versa convertersplitter
- MADI redistributor, patchbayrouter

ADI-648 is compatible to all forms of increasing the sample rate
(Double Speed). It supplies word clock in singledouble speed,
distributes 96 kHz signals in Double Wire mode into the MADI data
stream,per Sample Split (S/MUX) to the ADAT ports, but is also
capable of double MADI rate (96k Frame). The ADI-648 thus also
represents an ideal MADI front-end for the HammerfallHammerfall
DSP series.
SyncAlignSyncCheck technologies known fromproven by other
RME products, allow for perfect sync between all channelseasy
notification of error states. And of course multiple devices can be
cascadedsynchronized sample-accurate using word clock. The ADI-648
accepts 56 channels, 64 channels96k frame at its input,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" width1HU has numerous further outstanding
features, like Intelligent Clock Control (ICC)storing of the
settings. It´s even possible to transmit 16 MIDI channels in parallel
to all 64 audio channels. A fully automatic input ion between
opticalcoaxial input offers a useful redundancy mode for critical
applications. Extensive status displays give information about Lock and
Sync states, audio contentthe physical quality of the incoming
signal. A digital PLL, designed especially for the ADI-648, allows for
operation without an additional word clock line. The reference clock is
then extracted from the MADI signal itself.
The rear of the
ADI-648 looks cleartidy. Eight ADAT optical inputsoutputs

I/O (BNC) with switchable termination,two DIN MIDI jacks offer
unbeatable flexibilitycompatibility.
