The ADI-6432R from RME is 64-channel format converter, that features conversion from MADI to AES/EBU, and vice versa. MADI handles 64 channels of 24-bit audio at sampling frequencies up to 48kHz, 32 channels up to 96kHz and 16 at 192kHz. Dual redundant power supplies offer fail-safe operation for broadcasters and other professionals.
All channels are transferred across a single cable, using either a coaxial (BNC) or optical network cable. Typical applications could include two units for use as a digital multi-core, or a single unit used as AES/EBU front end for the Hammerfall DSP MADI PCI card.
The unit features RME’s SteadyClock, which provides very low jitter operation. Intelligent Clock Control retains the last valid sample frequency in case of a loss of the input signal. The front panel contains almost 100 LEDs for accurate and exact display of signal status. Errors can be spotted instantly and corrected, and the control keys can be locked to prevent accidental changing of settings.
- 64-channel MADI/AES format converter
- Support for up to 192kHz sample rates with MADI and AES
- SteadyClock allows for use of 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 – can be improved and refreshed, and subsequently be used as reference clock at the unit’s outputs
- Intelligent Clock Control (ICC) retains the last valid sample frequency in case of a loss of the input signal
- Supplies word clock in Single, Double and Quad Speed, distributes Double Wire 96kHz signals into the MADI data stream and to the AES ports and supports the double MADI sample rate (96k frame)
- SyncAlign and SyncCheck technologies ensure perfect synchronization and clear detection of errors
- Extensive status displays give information about Lock and Sync states, audio content and the physical quality of the incoming signal
- Every function has its own keys accompanied by clear function LEDs, allowing errors to be detected at a glance
- A fully automatic input selection between optical and coaxial input offers a useful redundancy mode for critical applications
- Multiple units can be stacked and operated sample-aligned, using Wordclock
- MADI Merge, using two units, allows two MADI streams to be merged from two sources, and sent on via a single MADI cable. Useful in situation where the two sources are not utilizing their full sixty-four channel counts
- The unit can be also used as a MADI to MADI converter. For instance, an AMS Neve Logic DFC only accepts the fifty-six channel input format. The ADI-6432 can read either format at its input or output
- The ADI-6432R can be used as an extender for serial cables, with no effect on the audio functionality, thanks to a RS232 9-pin COM port (9600, 19200, or 115200 Baud)
- 16 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
- All settings are stored when the unit is switched off
- Compatible to MADI interfaces of companies like Sony, Merging, Lawo, Euphonix, Stagetec, Jünger, Audio Service, AMS and others
- Redundant power supply which can be connected to two different electrical circuits – if one of these circuits fails, the unit will continue to operate normally
