RMEs ADI-6432 offers 64 channels of format conversion from MADI to AES and vice versa. Typical applications include two ADI-6432 used as digital multicore, or one unit used as AES/EBU frontend for the Hammerfall DSP MADI PCI card. Up to 192 kHz at 24-Bit are supported. Built with 2 units height there is enough space for all connectors and control elements. Of course the unit includes lots of typical RME-features:
The compact unit with 19" width and 2 unit height serves as format converter MADI to/from AES (schematic view). MADI handles 64 channels of 24-Bit audio at sampling frequencies up to 48 kHz, 32 channels up to 96 kHz, and 16 channels up to 192 kHz. All channels are transferred across a single cable, either coaxial (BNC) or optical network cable. In both cases, cable lengths of more than 100 meters can be achieved. The AES/EBU channels are provided as 32 AES/EBU inputs and outputs via D-sub connectors. The ADI-6432 accepts 56 channels and 64 channels as well as 96k frame at its input, and can be set to generate those formats at its output.
RMEs
SteadyClock(TM)
lets the ADI-6432 use MADI without an additional word clock connection, and guarantees excellent clock quality in every situation.
Due to the highly efficient jitter reduction, any clock signal - even AES and word clock - can be improved and refreshed,
and subsequently be used as reference clock at the word clock output.
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.
will retain the last valid sample frequency in case of a loss of the input signal.
The ADI-6432 supplies word clock in Single, Double und Quad Speed, distributes Double Wire 96 kHz signals into the MADI data stream,
and even supports the double MADI sample rate (96K frame). The
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.

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 other RME products ensure perfect synchronization and clear detection of errors.
Also multiple units can be stacked and operated sample-aligned, using word clock.
All settings are stored when the unit is switched off.
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 and sync states, audio content and the physical quality of the incoming signal.
The front panel features an exciting and detailed Sync and Audio State display with 97 LEDs. Furthermore there are lots of buttons with clear LED function display. Especially in a professional application, exact display and control of all incoming and outgoing signals, including MIDI and RS232, becomes indispensable. Errors can be detected at a glance. The control keys can be locked to prevent accidental changing of settings.
16 MIDI channels can be transferred invisibly across MADI, at the full count of 64 audio channels. The same applies to RS232: Be it 9600, 19200 or 115200 Baud, thanks to a 9-pin COM port, the ADI-6432 can be used as an extender for serial cables, with no effect on the audio functionality.
Additionally the device can be fully remote controlled and configured via MIDI, and all status displays can be queried through MIDI. Each ADI-642 can be given a separate ID, allowing separate remote controllability of various devices with only one MIDI channel.
The ADI-6432 is compatible to MADI interfaces of companies like Sony, Merging, Lawo, Euphonix, Stagetec, Jünger, Audio Service, AMS and others.
