Page 6: Introduction
The unique Intelligent Clock Control (ICC) allows for a flexible use with internal clock (44.1 up to 192 kHz), external word clock or the digital input signals. These options are intelligently coupled in a way typical for RME, and easy to apply thanks to a clear and easily understandable display of the Lock and Sync states. -

4. First Usage – Quick Start 4.1 Controls and Connectors The front of the ADI-6432 features nine buttons with 31 LEDs, and an extensive Status Display including 97 more LEDs. MADI INPUT determines current input for the MADI signal (optical/coaxial). The state of the... - Page 8 IEC receptacle for power connection. The specially developed, internal hi-performance switch mode power supply makes the ADI-6432 operate in the range of 100V to 240V AC. It is short- circuit-proof, has an integrated line-filter, is fully regulated against voltage fluctuations, and sup- presses mains interference.

MIDI remote control commands, and also the destination for the ADI- 6432's request replies. The standard MIDI ports or the MADI input and output can be chosen. LOCK KEYS allows to switch off all buttons. This way the ADI-6432 can be secured against accidental operating errors. -
Page 10: Accessories
The front panel has 8 female and 8 male XLR sockets. The device supports digital con- nection cables using Tascam and Yamaha pinout. To use all AES-I/Os of the ADI-6432 com- fortably and safely within a rack, four BOB-32 and eight digital connection cables are required. -

The AUDIO LEDs light up as soon as the digital signal carries an information other than digital zero. The channel doesn't matter. So there is only one channel of audio information necessary for the LED to light up. The amount of level is not indicated. User's Guide ADI-6432 © RME... -
Page 15: Clock
ADI-6432's internal clock. The SYNC state is indicated by a flashing (error) or constantly lit (OK) LED. The button STATE is used to configure the ADI-6432, and with this all of its outputs, to the fre- quency ranges Single Speed, Double Speed or Quad Speed. -
Page 16: Inputs
The ADI-6432 supports single wire only, in the range of 32 kHz up to 192 kHz: a total of 64 channels, 2 channels per AES wire. The effective sample frequency equals the clock on the AES wire. -
Page 17: Outputs
10. Outputs 10.1 MADI At the rear side of the ADI-6432 there are two MADI outputs. The BNC output is built according to AES10-1991. The output's impedance is 75 Ohm. The output voltage will be 600 mVpp when terminated with 75 Ohm. -
Page 18: Word Clock
The ADI-6432's transformer isolated word clock input is active when WCK is chosen in the clock section. The signal at the BNC input can be Single, Double or Quad Speed, the ADI-6432 automatically adapts to it. As soon as a valid signal is detected, the WCK LED is constantly lit, otherwise it is flashing. -
Page 19: Technical Description And Background
Thanks to a low impedance, but short circuit proof output, the ADI-6432 delivers 4 Vpp to 75 Ohms. For wrong termination with 2 x 75 Ohms (37.5 Ohms), there are still 3.3 Vpp at the out- put. 11.2 Operation and Technical Background In the analog domain one can connect any device to another device, a synchronization is not necessary. -
Page 20: Cables And Termination
(see chapter 11.1). In case the ADI-6432 resides within a chain of devices receiving word clock, plug a T-adapter into its BNC input jack, and the cable supplying the word clock signal to one end of the adapter. -
Page 21: Midi And Rs232
But what about MIDI? Be it remote control commands or sequencer data, in practice only a single MADI line will not suffice. Therefore the ADI-6432 also has a MIDI I/O port. The data at the MIDI input are being included into the MADI signal invisibly, and can be collected at the MIDI output of another ADI-6432, ADI-648 or a HDSP MADI, at the other end of the MADI line. -
Page 22: Remote Control Software
12.3 Remote Control Software A tiny Windows software can be downloaded for free from the RME website. It can use any existing MIDI port within the system to perform remote control and status requests of all ADI- 6432 via a simple mouse click. Most appealing is the combination with a HDSP MADI (PCI card), offering a direct control of the ADI-6432 via MADI. -

Page 24: Application Examples
13. Application Examples 13.1 Digital AES/EBU Multicore The ADI-6432 is perfectly suited to build up a digital AES/EBU multicore. Up to 64 channels can be realized, transmitted via MADI optical cable lossless and undisturbed to places in a distance of up to 2.000 meters. - Page 25 User's Guide ADI-6432 © RME...

Page 26: Madi To Madi Converter
There exist lots of other but similar examples. The ADI-6432 can serve here as a perfect link, because its MADI input can read any input for- mat. The ADI-6432's MADI output can be set to 56 channel or 64 channel output mode (see chapter 8.2). - Page 27 The number of ADI-6432s necessary is identical to the number of MADI signal sources, so it's two for this example. The first ADI-6432 serves as MADI to AES converter. Its AES outputs are connected to the AES inputs of the second ADI-6432. The second ADI-6432 is used as de- scribed in the above example, sending the MADI input signal directly to the MADI output.

Page 32: Firmware
14.6 Firmware The ADI-6432's main part has been realized using programmable logic. By re-programming of a little component called Flash-PROM, both function and behaviour of the unit can be changed at any time. At the time of writing this manual, the unit is shipped with firmware 1.4. The firmware version is displayed after power on for about one second by the SYNC and AUDIO LEDs of the AES INPUT STATE section. -

Page 34: Technical Background
The Quad Wire method allows to transmit two channels at up to 192 kHz via ADAT. The method is referred to as S/MUX4. Note: All conversions of the described methods are lossless. The existing samples are just spread or re-united between the channels. User's Guide ADI-6432 © RME... -
Page 35: Lock, Synccheck And Syncalign
Unfortunately, LOCK does not necessarily mean that the received signal is correct with respect to the clock which processes the read out of the embedded data. Example [1]: The ADI-6432 is set to 44.1 kHz internal clock, and a CD-Player is connected to input AES1. The corrsponding LED will start flashing immediately, but the CD-Player's sample rate is generated internally, and thus slightly higher or lower than the ADI-6432's internal sample rate. -
Page 36: Aes/Ebu - Spdif
The table shows that a Professional-coded signal would lead to malfunctions for copy prohibi- tion and emphasis, if being read as Consumer-coded data. Nowadays many devices with SPDIF input can handle Professional subcode. Devices with AES3 input almost always accept Consumer SPDIF (passive cable adapter required). User's Guide ADI-6432 © RME... -

64 channel format, but offer still no more than 56 audio channels. The rest is being eaten up by control commands for mixer settings etc.. The ADI-6432 shows that this can be done in a much better way, with an invisible transmission of 16 MIDI channels plus serial RS232 data stream, and the 64-channel MADI signal still being 100% compatible. -
Page 38: Steadyclock
The cleaned and jitter-freed signal can be used as reference clock for any application, without any problem. The signal processed by SteadyClock is of course not only used internally, but also available at the ADI-6432's word clock output. It is also used to clock the digital outputs MADI and AES/EBU. -
