1. Introduction
The MADI Bridge provides you with a versatile and powerful 8 x 8 patchbay for MADI signals.
As a consequent continuation of RME's world-wide successful MADI series, the MADI Bridge
also contains elaborate technology and the latest integrated circuits. In a few words: The MADI
Bridge is a uniquely powerful and high-quality device, which will excite you even after many
years of operation.
2. Package Contents
Please check that your MADI Bridge package contains each of the following:
• MADI Bridge
• Manual
• Power chord
3. Brief Description and Characteristics
Developed as the optimal missing link between MADI devices of any manufacturer, RME's
MADI Bridge serves as patchbay, distributor, signal buffer and input selector - and is thus
mandatory for every MADI user. Up to 16 devices can be freely connected with each other by 6
coaxial (BNC) and 2 optical in- and output pairs. Thanks to an intuitive and easy to navigate
user surface, the device is easy to understand and to operate – even without a manual. Additionally the MADI Bridge can be remote controlled via MIDI.
All input signals are routed unaltered to the desired outputs. Like this, the MADI Bridge supports any format, no matter if it is 56 or 64 channels or includes special invisible control commands, any sample rates and even out-of-spec data rates, or violations of the MADI protocol.
Thanks to a highly sensitive input stage, coaxial cable lengths of 100 m can be used - even
between several devices.
4. Firmware
The MADI Bridge's main part has been realized using programmable logic. By exchanging a
little component called EPROM, 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 1.1. The firmware version is
displayed after power on by the channel LEDs for about one second.

6. First Usage
6.1 Quick Start
The user interface of the MADI Bridge is characterized by a clearly structured architecture and
an unambiguous labelling of the front and rear sides. The device can thus be used easily without a manual, because numerous displays show the state of the device in a strictly logical way.
However, we don't want to hold you back from reading this manual, as it includes a lot of important and useful information.
The follwing information is important to know for a successful usage of the unit:
• The alpha numerical input displays of the eight outputs always show the REAL state. Select-
ing a different input via the Up/Down keys, both display and routing change immediately.
• The 64 dot matrix shows the configuration of the selected preset. So when stepping through
the presets the matrix display serves as preview.
• Directly after loading a preset (Recall) both matrix and alpha numerical displays show the
REAL state. Changing the routing via the Up/Down keys does not cause a change in the
matrix display. The changed channel displays get marked with a dot, to indicate a setting
different from the formerly loaded preset (and with this from the matrix display).
• The preset 0 can not be edited. It interrupts (disconnects) all connections, thus operates
like a MUTE functionality.
• The preset NONE (no number displayed) is no preset, therefore does not react on Save and
Recall. In this setting the matrix shows the current routing instead of the currently selected
preset. Changes via the Up/Down keys can then be monitored in real-time in the matrix display.
• To prevent accidental operating errors, the keys STORE and RECALL react delayed. For
the specific function to be executed, the keys have to be pressed at least for a second.
The MADI Bridge remembers all settings before switching off and sets them automatically
when switching on the next time.

6.2 Operation
The Lock section allows both locking the keys on the device and locking the MIDI remote. This
way the device can be secured against accidental operating errors.
The front panel has eight output
fields. This clarifies the way the
MADI Bridge operates. An output can
be fed by any input, multiple outputs
can be fed even from the same
input. This way the device can be
used as distributor.
But it's not possible to route more than one input to one output. This would equal the functionality of a digital mixing desk, requiring the ability of mixing digital signals.
Eight alphanumerical LED displays seperately show the current
signal source for each output. Using two keys, the Up/Down keys,
the input source can be changed quickly. Besides input 1 to 8, input 0
(no input) can be chosen as well.
Above each configuration field, an empty label area allows to attach
a tape to each output, with the name of the connected device. With
this, the routing stays clear and easy to understand, even when all
I/Os are in use.
The device stores the last settings when being switched off. The
current setting can also be stored as Preset. The section Presets
offers 9 free memories. Memory 0 is pre-configured as panic button,
it cancels all connection points.
A preset is pre-selected first. The matrix field shows the configuration
of the pre-selected preset. The desired preset is then loaded with the
Recall key. As soon as one of the routings is being changed, both the
changed output and the preset number show a dot in the display.
The 64 LED matrix field displays all routings in classical matrix
view, a configuration can be viewed and understood in a glance.
The matrix field is especially valuable for pre-selection of the
presets, because the preset's routing is displayed in the matrix
before recall. The preset NONE (no number displayed) switches the
matrix into real-time display, showing the current routing.
The crosspoints of identical inputs/outputs are marked by red warning LEDs. A routing of an
output to the same input causes a feedback when connecting external devices. Therefore, in
most cases this kind of connection makes no sense. As such a connection might be desired in
specific cases (see chapter 9.1), it is still available in the MADI Bridge.

7. Inputs and Outputs
7.1 MADI Inputs
The rear of the MADI Bridge has six coxial MADI inputs, available as BNC sockets. The sockets are ground-free and seperated from ground by capacitive coupling. This method prevents
ground loops and other distortions by potential differences between the connected units. Note
that the the transmission at the receiver still operates unbalanced.
The BNC input's ground-free design is built according to AES10-1991. The input's impedance is
75 Ohm. It will operate error-free from about 180 mVpp.
The two optical inputs use a FDDI (ISO/IEC 9413-3) compatible optical module each, according
to AES10-1991. More information can be found in chapter 10.1, MADI Basics.
7.2 MADI Outputs
The rear of the MADI Bridge has six coxial MADI outputs, available as BNC sockets.
The BNC outputs are built according to AES10-1991. The output impedance is 75 Ohm. The
output voltage will be 600 mVpp when terminated with 75 Ohm.
The two optical outputs use a FDDI (ISO/IEC 9413-3) compatible optical module each, accord-
ing to AES10-1991. More information can be found in chapter 10.1, MADI Basics.
7.3 MIDI Input and Output
The rear of the MADI Bridge offers one MIDI input and output via two 5-pin DIN jacks. The
MIDI input can be used to remote control the MADI Bridge. The MADI Bridge sends out status
information via the MIDI output. All MIDI data at the MIDI input are passed on to the output, a
method known as MIDI Thru function. This way the MADI Bridge can be easily integrated (inserted) into existing cablings and setups.

8. Software MIDI Remote
8.1 MIDI Control of the MADI Bridge
The MADI Bridge can be completely remote controlled via MIDI. It reacts on commands directed to the specific unit. Furthermore, on request the complete status is send back, which
includes all front panel displays and key states. Each MADI Bridge can be programmed with its
own ID. This allows to remote control multiple units, even via the same MIDI channel. A detailed description of the MIDI commands can be found in chapter 13.
The key LOCK MIDI turns off MIDI remote. This safety function prevents the current setup from
unintended changes by MIDI commands. All input data are still passed through to the MIDI
output.
Especially recommended is the combination of HDSP MADI and ADI-648. They transmit MIDI
directly embedded in MADI, thus allow controlling a MADI Bridge which is located far away
from the computer.
8.2 General Notes on Operation
RME's free Windows software MIDI Remote is an extraordinairy MIDI remote control program.
MIDI Remote allows for configuration and status request of different RME devices by a simple
mouse click. Both ADI-648 and MADI Bridge are fully supported. The communication uses any
free MIDI port available in the system.
Software download: http://www.rme-audio.de/download/midiremote.zip
After connecting the MADI Bridge to a MIDI port
present in the system (input and output), start the
software MIDI Remote. In the menu Function
(or via F4) select the entry MADI Bridge Matrix.
Next select the used MIDI port in the menu
Options, MIDI I/O Setup (or use F3).
In the upper part of the window the current status
of the communication is shown. It starts Offline.
Via the menu Options, Connect MIDI Ports, or
by a click on the Power icon in the Toolbar (third
icon from the left) the MIDI communication is
started. Now the State field changes to Online.
In case the display changes to No Response the
program does not receive any reply from the
MADI Bridge. Most probably this is caused by the
usage of a wrong ID. The MADI Bridge has been
programmed to ID 00 in the factory. When the
device ID 00 or All are selected in the program,
the communication must work. The device ID
can be changed by a double click on the black
field Device ID.

8.3 Brief description of the menu entries, Function MADI Bridge Matrix
File – New MIDI Remote Window
The program MIDI Remote is capable of multi-client operation. There is no limit in opening
windows and thus controlling as many units at the same time as desired.
File – Open and Save Setup
All settings can be stored in and loaded from a file. This is especially useful to quickly load
different routings, or to access different units with different IDs.
File – Load and Save Workspace
The settings and the position of multiple opened windows can be saved and loaded from a
workspace file. In contrary to the settings file, the used MIDI ports are also stored and loaded.
Function
At this time, the MIDI Remote includes three operation windows: a front panel view of the ADI648, a matrix view of the ADI-648, and a matrix view of the MADI Bridge.
Options – Connect MIDI Ports
Start / Stop of the MIDI communication. In the upper part of the window the current state is
shown, like selected ID, Online / No Response / Offline.
Options – Send Single Set of Data
In Offline mode the program can be used to just send a single set of commands. With this, a
change of the configuration can be performed at a specific moment. Additionally the load on
the MIDI line is reduced, as no ongoing communication is taking place.
Options – Select Device (F2)
Opens a dialog box to select a device ID. Choosing 'All', the current device ID of the unit is
ignored. The setting 'All' is not allowed when using more than one MADI Bridge.
Options – MIDI I/O Setup (F3)
Opens a settings dialog to configure the MIDI input and output port. This setting can be different for different windows (views).
Options – Function Select (F4)
Opens a settings dialog to select the current function. At this time, the MIDI Remote includes
three functions: a front panel view of the ADI-648, a matrix view of the ADI-648, and a matrix
view of the MADI Bridge.
Options – Edit Device Namens
Opens a settings dialog to assign a name to each device ID.
Options – Set I/O names to default
Double click on the the name fields in the matrix to type in any desired name. This option sets
all fields back to the factory names.
Options – Ignore Position on Setup Load
With this option active, the window position stored in a setup file is not used when loading the
setup. So the current window position will not change.
Options – Program Device ID
Opens a settings dialog to program a device ID into the MADI Bridge. Note: programming is
fast and not confirmed. Attention: Programming is only possible when not more than one MADI
Bridge is connected via MIDI!

9. Configuration Examples
9.1 Distribution 1 to 8
Use the Up/Down keys to select 'INPUT 1' on all channels. The
matrix displayes a horizontal line in the most upper line.
The input signal from input 1 is now sent to all eight outputs of the
MADI bridge at the same time (in parallel).
9.2 Passing On the signal
Use the Up/Down keys to set all inputs one below the current output
channel. Output 1 is set to input 8, output 2 to 1, output 3 to 2 and
so on. The matrix shows a 45° line from upper left to lower right,
shifted one LED to the right of the red LEDs. In this configuration
the input signal 1 is sent to the output 2, input 2 to output 3 and so
on. With this, all MADI devices are connected in a serial way.
9.3 Conversion Optical to Coaxial and vice versa
Of course, the MADI Bridge can also serve as format converter from coaxial to optical, and at
the same time from optical to coaxial. Thanks to its two optical I/Os, both functions are even
available two times!
Coxial to optical: Configure output 7 and/or 8 to use one of the six
coaxial inputs.
Optical to coaxial: Configure output 1 to 6 to use the optical input 7
and/or 8.

10. Technical Background
10.1 MADI Basics
MADI, the serial Multichannel Audio Digital Interface, has been defined already in 1989 as an
extension of the existing AES3 standard following several manufacturers' wish. The format also
known as AES/EBU, a balanced bi-phase signal, is limited to two channels. Simply put, MADI
contains 28 of those AES/EBU signals in serial, i. e. after one another, and the sample rate can
still even vary by +/-12.5%. The limit which cannot be exceeded is a data rate of 100Mbit/s.
Because an exact sampling frequency is used in most cases, the 64 channel mode was introduced officially in 2001. It allows for a maximum sample rate of 48 kHz + ca. 1%, corresponding to 32 channels at 96 kHz, without exceeding the maximum data rate of 100 Mbit/s. The
effective data rate of the port is 125 Mbit/s due to additional coding.
Older devices understand and generate only the 56 channel format. Newer devices often work
in the 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-648 and the HDSP MADI show that
this can be done in a much better way, with an invisible transmission of 16 MIDI channels and
the MADI signal still being 100% compatible.
For the transmission of the MADI signal, proved methods known from network technology were
applied. Most people know unbalanced (coaxial) cables with 75 Ohms BNC plugs, they are not
expensive and easy to get. The optical interface is much more interesting due to its complete
galvanic separation, but for many users it is a mystery, because very few have ever dealt with
huge cabinets full of professional network technology. Therefore here are some explanations
regarding 'MADI optical'.
• The cables used are standard in computer network technology. They are thus not at all
expensive, but unfortunately not available in every computer store.
• The cables have an internal fibre of only 50 or 62.5 µm diameter and a coating of 125 µm.
They are called network cables 62.5/125 or 50/125, the former mostly being blue and the
latter mostly being orange. Although in many cases not clearly labeled, these are always (!)
glass fibre cables. Plastic fibre cables (POF, plastic optical fibre) can not be manufactured
in such small diameters.
• The plugs used are also an industry standard and called SC. Please don't mix them up with
ST connectors, which look similar to BNC connectors and are being screwed. Plugs used in
the past (MIC/R) were unnecessarily big and are not being used any longer.
• The cables are available as a duplex variant (2 cables being glued together) or as a simplex variant (1 cable). The ADI-648's opto module supports both variants.
• The transmission uses the multimode technique which supports cable lengths of up to almost 2 km. Single mode allows for much longer distances, but it uses a completely different
fibre (8 µm). By the way, due to the wave-length of the light being used (1300 nm), the optical signal is invisible to the human eye.

10.2 MADI Bridge Technology
A MADI patchbay basically can be realized in two ways: using a complete signal regeneration
(including reclocking), or by a buffered distribution of the un-processed input signal.
Complete Signal Regeneration: This method requires a complete MADI receiver per input,
and a complete MADI transmitter per output. The signal must be processed and reclocked. The
costs are extreme, as the special MADI chip (required 8 times!) is already very expensive. Additionally another very powerful FPGA is necessary. Operation gets clumbersome, as the unit
has to provide full clock support and control. The advantage is that the MADI signal at the output is completely independent from the quality of the input signal, as it is fully newly generated.
Buffered Distribution: This method uses a sensitive receiver to amplify the input signal to a
standard level, then puts out this signal with an active driver stage. The signal is not processed
nor reclocked. The different combinations (routings) of the input and output signals as well as
the MIDI control can be performed by a fast FPGA. The component costs are dramatically
lower compared to the Signal Regeneration method. The operation is very easy, as the current
clock situation is completely ignored. The disadvantage is that the quality of the output signal
depends on that of the input signal, as the signal is passed on nearly unchanged. Additionally
the maximum coaxial cable length is reduced, as a signal to/from the MADI Bridge travels double the distance.
RME's MADI Bridge uses adapted termination and a special equalizing, to reach higher cable
lengths despite its simpler design. The MADI Bridge can even serve as cable buffer for the
limited outpus of some manufacturers (90 meter coaxial instead of 30 meter...).
Real world tests with MADI devices of various manufacturers confirmed the outstanding performance of the MADI Bridge. There exists only one exception: The output signal of the Sony
3348 (digital tape machine of the first MADI generation) becomes unreadable when passed
through the MADI Bridge. Fortunately this problem was easy to be fixed. The inputs 5 and 6 of
the MADI Bridge can be made compatible to the 3348 by internal jumpers.
10.3 Setting Inputs 5/6 into Compatibility Mode (Sony 3348)
Before opening the unit, make sure the power cable is disconnected from the mains supply.
Risk of electric shock by high voltage inside the unit!
1. Disconnect the power cord and all other cables from the MADI Brigde.
2. Remove the rack ears using a screwdriver (Phillips 1, 2 screws per ear).
3. Remove the screws of the cover (7 screws).
4. Slide the cover to the back and remove it.
5. Jumper JP1 and JP2 are placed near the BNC jacks of input 5 and 6. The jumper position is
printed to the left on the pcb. The factory default is the setting 'Standard'. Changing the jumpers to the other position activates the Sony 3348 mode.
6. Put the cover back on and slide it into the front panel's frame, so that all 7 screws can be refit and tightened.
7. Mount the rack ears.
8. Connect power and other cables.
