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. Addi-

tionally the MADI Bridge can be remote controlled via MIDI.

All input signals are routed unaltered to the desired outputs. Like this, the MADI Bridge sup-

ports any format, no matter if it is 56 or 64 channels or includes special invisible control com-

mands, 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 with-

out 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 impor-

tant 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 dis-

play.

•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.

6User's Guide MADI Bridge © RME

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 functional-

ity 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 sock-

ets 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 (in-

serted) into existing cablings and setups.

8User's Guide MADI Bridge © RME

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 di-

rected 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 de-

tailed 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.

User's Guide MADI Bridge © RME 9

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 ADI-

648, 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 differ-

ent 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.
