RME
ADI-6432 / 6432R

BIDIRECTIONAL 64-CHANNEL 192 KHZ
MADI <> AES/EBU FORMAT CONVERTER

CONNECTIVITY

32 x AES/EBU I/O
1 x MADI optical I/O
1 x WordClock I/O
1 x Com-Port I/O
1 x MIDI I/O

The ADI-6432 converts all 64 channels of a single MADI stream to 32 AES/EBU ports and vice versa. Thus it supports all 64 channels of the MADI format at up to 48 kHz, 32 channels at up to 96 kHz and 16 channels at up to 192 kHz. Connected to the HDSP(e) MADI interface, the ADI-6432 turns into a powerful external 32-port AES/EBU interface. Two units will build a perfect digital multicore solution without any computer needed.

The RME ADI-6432 R is identical to the ADI-6432, but can be connected to two different electrical circuits. If one of these circuits fails, the ADI-6432R will continue to operate without interruption.

The unit includes lots of typical RME-features::

Support for up to 192 kHz with MADI and AES
Unique status displays for MADI and AES
SteadyClock for maximum jitter reduction and clock regeneration
Completely remote controlable via MIDI
Transfer of MIDI data via MADI
Transfer of RS232 data via MADI

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.

FEATURES

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) 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 ® and SyncCheck ® 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 every function has its own keys accompanied by clear function LEDs. Especially in a professional application, exact, quick and direct control and display 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.

SERIAL / MIDI EXTENDER

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-6432 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.
