1. Introduction

The RME MADI Router is designed to be the centerpiece of small and large digital audio

networks based on the widely adopted point-to-point Multichannel Audio Digital Interface

(MADI alias AES10).

It is able to manage all the tasks that are required to set up and to control a MADI

environment, from inspection of signal integrity and sampling frequency, to format

conversion, to full stream and single-channel block routing. It supports a variety of

common physical interface formats of MADI including optical and coaxial, supplemented

by the evolving twisted pair variant, which allows much simpler and more affordable

MADI setups.

2. Package Contents

Please check that your MADI Router package contains each of the following:

● MADI Router

● 2 rack ears with screws

● 2 power cords

● User’s guide

3. Brief Description and Characteristics

The MADI Router is a compact device designed to link MADI devices of any

manufacturer with unprecedented flexibility in signal routing. It provides this flexibility by

serving as a format converter between optical and electrical signals, as a signal repeater,

and as a distributor and merger of several MADI signals, all at the same time. The MADI

Router combines many advantages of point-to-point audio connections, such as low

latency and fast recovery time from signal line interruptions, with the flexibility of

networked audio connections in which any device has access to any channel available

on the network of connected devices.

At the simplest level all input signals are passed on to the desired output unaltered. This

type of connection is beneficial when manufacturers have embedded additional status

or remote control data information in the MADI stream, or if parts of the MADI signals

should be re-routed at the touch of a button, for example if a stage box fails.

It is also possible to create new arrangements of audio channels within a MADI output

stream. For this purpose 4 independent ‘virtual’ matrices are provided, each of which

comprises 768 input and 64 output channels. As such, any of the 768 audio channels

that make up the 12 physical MADI input ports can be used to compose a 64 channel

output from this matrix. This 64 channel 'virtual' matrix output can then be sent to any of

the MADI Router's 12 physical MADI output ports.
