1. Introduction The MADI Bridge provides you with a versatile and powerful 8 x 8 patchbay for MADI signals. As a useful addition to 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.

. 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.
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.
7. Inputs and Outputs 7.1 MADI Inputs The rear of the MADI Bridge has six coaxial MADI inputs, available as BNC sockets. The sockets are ground-free and separated from ground by capacitive coupling. This method prevents ground loops and other distortions by potential differences between the connected units. Note that 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.
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.
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.
9. Configuration Examples 9.1 Distribution 1 to 8 Use the Up/Down keys to select 'INPUT 1' on all channels. The matrix displays 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.
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.
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.
