Introduction

Overview

MADI Bridge is an interface between a routable Audio-over-IP network and MADI (AES10). SSL
Network I/O products use Audinate’s Dante technology to transport audio, plus discover and
configure multiple devices on the network. Using Dante results in seamless and reliable
interoperability with third party Dante products, this is further expandable with AES67 compatibility.

With 64 channels per MADI Bridge (at 48kHz) and up to 512 channels per 1Gb network link, Dante is
fully scalable and capable of providing routing channel counts from tens to thousands and beyond
using standard IT infrastructure. Redundant PSUs, MADI and IP Network ports mean the MADI
Bridge is built for uninterrupted operation, keeping critical devices and audio paths functioning
throughout the system. In addition to the inbuilt clock redundancy options in Dante Controller, the
MADI Bridge also includes a pair of redundant sync inputs for use as a self-redundant Dante Grand
Master clock.

The MADI Bridge features a front panel headphone socket (with rotary level control) and inbuilt
headphone monitor routing, to replace traditional patchbay routing and fault finding functionality
with equivalents in the IP audio domain. Simple front panel controls facilitate routing mono or stereo
paths from MADI In, MADI Out, Dante In or Dante Out directly to the headphones. A front panel
OLED screen provides signal present metering, selectable to show four points in the signal chain:
MADI In, MADI Out, Dante In and Dante Out. GPIO connections allow the transfer of tallys and
switching functions across the same network as the audio.

Key Features

● Interface between MADI and IP Audio Networks using Dante and AES67

● Bi-directional sample rate conversion between any asynchronous sample rates, from 44.1kHz

to 192kHz

● Redundant PSUs, MADI ports, Dante ports, sync inputs

● MADI Split Mode

● GPIO connectivity - embed tallies across the network

● Redundant Network Extension ports - add local IO or control without a switch

● Wordclock out - clock a MADI device to the Dante network

● Virtual Headphone Patch

● Lockout mode - prevent accidental alteration of front panel settings

Virtual Headphone Patch



Monitoring and signal present metering is provided for incoming and outgoing MADI and Dante
ports. It replaces patchbay based routing with a digital network whilst retaining confidence and fault
finding tools.



Audio Channel Names

The name of the signal (as set in Dante Controller) being transmitted or received over the network
can be displayed in the status and monitoring window for the selected channels.

Usage Cases

N.B. The following diagrams omit secondary network connections for clarity.

MADI Connectivity for a System T Network

This provides MADI connectivity available to all networked System T consoles. The MADI Bridge can
also be used as a clock master for the Dante network or to provide external TDM devices with a
clock source.


Dante Network I/O Integration for MADI Consoles

This allows the addition of Dante networked devices to existing MADI infrastructure.



Leveraging Existing Network Infrastructure

Up to 8 MADI streams can be transmitted through 1Gb bandwidth - 512 channels at 48 kHz in each
direction.

Redundant or Split Mode MADI

The secondary MADI input can be used as a redundant backup of the primary input, or as a second
MADI input when in Split Mode. Here the MADI channel allocation is divided between the ports,
dependant on the MADI and Dante sample rates. Full Split Mode channel allocation details are shown
in Appendix C .

Hardware Connections

Mains Power Connections

The MADI Bridge includes redundant PSUs with IEC connectors; either supply can
individually power the unit. Ideally these should be connected to separate power
circuits to provide redundancy of incoming AC power.



Dante Connections

MADI Bridge has two redundant sets of network connections.

Note: Some Dante devices allow Dante ports to be set to Switched mode rather than Redundant
mode. MADI Bridge uses the extension ports to provide this functionality, without loss of
redundancy.

Never connect Primary and Secondary ports to the same single Dante network.

Software Features

The front panel interface is designed to be intuitive to allow access to any function that needs to
change using minimal button presses. Each menu has its own individual radio button that navigates
to the desired page on the OLED. The other front panel control is the SELECT encoder which can be
rotated, pushed or pushed-and-held.


Info Menus


The info menus are accessed by individual buttons to instantly navigate to the desired settings page
on the OLED display. These menus are:

LOCK – Front panel lockout and device information
MON – Metering and headphone monitoring

LOCK

The LOCK button is dual function: it both locks the front panel and displays the info screen on the
OLED Display. MADI Bridge automatically locks-out the front panel after 60 seconds of the SELECT
encoder or button inactivity. After a total of 2 minutes of inactivity the OLED display enters a
screensaver mode. To unlock the front panel, press and hold the LOCK button for 3 seconds. When
already in the LOCK menu, pressing and holding the LOCK button for 3 seconds will lock the front
panel.

Note that the Monitor ( MON ) menu remains accessible even whilst in front panel lockout.

N.B. Holding both the LOCK and Z buttons together for 3 seconds restarts the MADI Bridge.

The default Info page shows the following information:

Page 10 of 30

MADI Bridge User Guide Contents

Turning the SELECT encoder scrolls through the info pages:

MON

Pressing the MON button brings up the Monitor menu or Channel Name page. Press the MON
button again to navigate between these pages. The chosen page will be remembered when
navigating to the MON page in future.

When in the Monitor menu, rotating the SELECT encoder alters the parameter highlighted by the
focus box on the left. Pushing the encoder scrolls down through the 4 options. These options are:

● Headphone volume

● Signal location

● Channel number

● Format



By default when entering the monitoring page the encoder will adjust the headphone volume.
Pressing the SELECT encoder will move the focus to alter Signal Location . The options are:

● M-I MADI Input

● M-O MADI Output

● D-I Dante Input

● D-O Dante Output

When Channel Number is in the focus box rotating the
encoder moves through the channels. This is displayed both
by the channel number and the focus box around the signal
present meters.

Format. When a Stereo channel is selected the left channel
number is displayed and the focus box surrounds 2 signal
present meters.

The Channel Name view displays the ‘Channel Label’ name
as entered in Dante Controller. When looking at D-I or M-O
the name displayed will be the channel label and the device
that is routed to the unit across the network.

Options Menus

The Options menus include parameters to be changed from the front panel and display information
that needs to be known when changing options. These menus are:

The Options menus are accessed by individual buttons to instantly navigate to the desired settings
page on the OLED Display. The front panel must be unlocked for these buttons to function.

Within each Options menu the OLED display is divided into four focus sections:

The lower half of each focus box displays the option to be changed, the upper half displays the
parameter it is currently set to. Turning the SELECT encoder moves the focus window across the 4
sections.

The action taken when pressing the SELECT encoder differs depending on the colour of the box in
the lower half of the focus window: a yellow option toggles through the parameters, a grey option
requires a press and hold (3 seconds) to engage a detect routine or to force a special state, a solid
black option indicates information only ( SELECT has no function).

Error Indication

Errors will cause the appropriate Options menu button LED to flash, indicating which menu needs
attention or where information relating to the error’s cause can be found. If an error occurs the
MADI Bridge front panel will automatically unlock and be prevented from entering the screensaver
mode until the the error is resolved. Causes for error indication are shown in the following REDU ,

CLOCK and SRATE sections.

 

MADI

The MADI menu allows you to set the MADI settings. This is used to match the MADI parameters
with those of another MADI device for valid interoperability.

Pressing the MADI menu button brings up the MADI menu. With
the focus box selected to MADI Mode , pressing the encoder
cycles through the MADI mode options ( Auto , 64ch , 56ch , 32ch ,
28ch , 16ch , 14ch ).

The options available depend on the MADI sample rate.

● MADI sample rates of 192 or 176.4 kHz allow 14 or 16
channel mode

● MADI sample rates of 96 or 88.2 kHz allow 28 or 32
channel mode

● MADI sample rates of 48 or 44.1 kHz allow 56 or 64
channel mode

● Auto mode will detect the format of the incoming MADI
stream and display the channel number

● Auto mode will display ERROR if the channel mode cannot be determined

Legacy (SMUX) format MADI at 192, 96 or 88.2 kHz is not supported.

N.B. It is not advised to use two devices with auto-detect modes
at either end of a MADI link.

Turning the encoder clockwise moves the yellow focus box to the
SRC option. Pressing the encoder toggles the sample rate
converters on and off.

In the MADI SRATE window pressing the encoder has no
function. The MADI sample rate is derived from the primary clock
input – see CLOCK and SRATE menus.

The fourth focus window shows MADI R State as displayed in the

REDU menu.



N.B. The MADI Tx continues to function when a MADI Rx signal is not received. While this is a
perfectly usable state for some scenarios, the units error flagging will treat this as an error as there
is no MADI Rx signal. When in this state:

● The front panel will show an error as there is no valid MADI Rx signal

● The unit will not lock the front panel buttons

● The unit's OLED will not enter screen saver mode

● The Monitoring feature will be unavailable for all signal points: MADI In, MADI Out, Dante In

and Dante out

REDU

The REDU (Redundancy) menu allows you to set up the MADI redundancy options when interfacing
various MADI devices. In addition, it provides fault-finding tools to continuity-check the validity of
MADI signals directly from the front panel, or instigate Forced Override should you need to override
the automatic redundancy mode.

Pressing the REDU menu button brings up the MADI Redund

Mode Options Menu. With the focus box selected on Redund
Mode pressing the encoder toggles through the options:

● SSL – SSL mode is for integration with SSL consoles that
turn off the MADI signal on the dormant port

○ The REDU LED will flash if you are in SSL Mode

(Dark Fibre) and both MADI inputs are valid

● GPI – The Bridge defaults to the primary MADI input but
can be forced to the secondary by triggering GP input 1

For GPIO pinouts refer to Appendix D .

● None – The MADI ports are now in Split Mode

None (Split) mode is not available at 176.4 or 192 kHz
sample rates. For channel allocation details refer to Appendix C .

Turning SELECT clockwise moves the focus box to the MADI R
State option, pressing SELECT has no function. The option reports

the MADI redundancy state and as such the MADI input bridged to
Dante ( Pri , Sec , Pri Error , Split Mode ).

When in GPI mode this reports the GPI state. When in SSL mode
this reports the active MADI port or, if both are active reports Pri
Error , as one MADI connection should be ‘dark’. In SSL mode, if
neither port is active, the unit defaults to the primary port.

Turning SELECT clockwise moves the focus box to Pri MADI Rx ,
this option is primarily for reporting only. However, for fault-finding
and recovery this can be used to force MADI to the primary port.
Pressing and holding SELECT for 3 seconds will put the MADI
Bridge into Force Primary Override mode.

While in this state the display will say Force and the REDU menu
LED will flash to warn that Force mode has been enabled. Pressing
and holding SELECT again for 3 seconds will revert to normal
operation.

There is also a Force Secondary Port Override option when focus is
on Sec MADI Rx . Press and hold SELECT for 3 seconds to engage
and revert to standard.

CLOCK




The CLOCK menu allows you to set the primary and secondary clock sources and enable the Auto
Detect routine for each source.

Pressing the CLOCK menu button brings up the Clock page. With
Pri Clk in the focus window pressing the SELECT encoder cycles
through the clock options ( Ext A , MADI , Dante ).

The clock source selected in Pri Clk is not enabled until the Auto
Detect routine is enabled in Pri Detect .

Turning SELECT clockwise moves the focus box to Primary Detect.
Pressing and holding SELECT for 3 seconds starts the auto detect
routine; this lasts for 20 seconds.

When Ext A is the Pri Clk source the Auto Detect will determine if
the attached clock is video or wordclock. If the source is wordclock
it will determine the sample rate; if the source is video the video
sample rate will need to be set in the SRATE menu.

Turning SELECT again moves the focus to Sec Clk , pressing
SELECT cycles through the options ( Ext B , MADI , Dante , None ).

None should be used to disable the secondary clock input if
nothing is required.

Again the secondary clock Auto Detect routine can be enabled by
pressing and holding the SELECT encoder when Sec Detect is in
focus.



N.B. With SRC on, the clocking options do not include Dante. Dante clocking is determined in Dante
Controller.

The CLOCK LED will flash if the MADI Bridge has swapped over to the secondary clock. A manual
detection of the primary clock is needed to force it to the primary clock.

Page 15 of 30

MADI Bridge User Guide Contents

SRATE




Sample rate reporting and setting if using video sync.

Pressing the SRATE menu button brings up the Sample Rate
menu. If the primary clock is MADI, Dante or wordclock it
automatically detects the sample rate using the primary clock Auto
Detect routine in the CLOCK menu.

If the primary clock source is video this option becomes manual
(signified by being highlighted yellow) – pressing SELECT toggles
through the sample rate options ( 44.1 , 48 , 88.2 , 96 , 176.4 and
192 kHz).

Turning SELECT clockwise moves the focus box to Sec Clk Info .
If the secondary clock is MADI, Dante or wordclock it automatically
detects the sample rate using the secondary clock Auto Detect
routine enabled in the CLOCK menu.

If the secondary clock source is video this option becomes manual
(signified by being highlighted yellow) – pressing SELECT toggles
through the sample rate options ( 44.1 , 48 , 88.2 , 96 , 176.4 and
192 kHz).

With the focus box on MADI Info the encoder has no function, the
MADI Info sample rate follows that of the primary clock sample
rate.

With the focus box on Dante Info the encoder has no function,
Dante Info reports the Dante sample rate set for the MADI Bridge
from Dante Controller.

The SRATE LED will flash if the sample rates do not match and SRC is switched off.

MODE






The MODE menu allows you to set the Control Mode . The Control Mode setting is required when
AES user and control bits are to be transported between devices on the Dante network.

N.B. On older design MADI Bridge devices the MODE button is labelled U .

To enable the pass-through of AES user and control bits the MADI Bridge must be set to PCM 32
encoding within Dante Controller. Changing the encoding setting is detailed in the Dante Controller
section of this guide.

N.B. When set to 32-bit encoding the audio remains 24-bit. The additional 8 bits are used to
transport the user and control bits from the AES10 signal.

Pressing the MODE menu button brings up the Control Mode page. If 32-bit encoding is enabled
then pressing the SELECT encoder cycles through the available options ( SSL , AES10 ).

● SSL mode is for use with SSL devices such as the
Alpha-Link LIVE - control data is transferred in the upper
audio channels

N.B. For SSL Control Mode (and any other manufacturers’
control modes using higher audio channels and user bits for
control) all audio channels must be routed one-to-one
between the two MADI Bridge devices.

● AES10 mode enables transparent pass-through of the user
and control bits from the signal

If the MADI Bridge is set to PCM 24 encoding the Control Mode
will be fixed to None . No user or control bits will be passed
through.

MADI Bridge User Guide Contents

Dante Controller

Refer to Audinate’s Dante Controller user guide for complete information on Dante Controller
software. The information below details the basics required to get started.

Clock sync, device naming and network management are all done within Dante Controller.

Dante utilises the device name for routing. Each device must have a unique name – if a name is
duplicated it will be appended with a number.

Network Config

Each device requires its own unique IP address. This may be automatically configured, provided by a
DHCP server or assigned manually. The primary and secondary ports must not be connected to the
same logical network. Ideally, separate switching hardware should be provided for primary and
secondary networks. Creating VLANs on shared hardware is acceptable but does not provide the
most robust redundancy.

The Default display in the LOCK mode shows the primary IP address; in this way you will always be
able to access the device regardless of what mode the network ports are set to.

Device Info

The Device Info tab shows an overview of all devices on the Dante network including name,
product type, software version, IP address, link speed and status.

Device > Device View provides configuration and diagnostics for each device including Tx and Rx
subscription and signal status, software and firmware version information, network utilisation and
real-time latency measurement, as well as configuration of device name, sample rate, bit depth,
latency, IP address and AES67 parameters. The Network Config tab provides IP address
configuration options.

The device will resolve to a link-local address if it is set to obtain an IP address automatically and no
DHCP server is present. To access via link-local, set your computer to obtain an IP address
automatically, directly connect to the device’s primary port and wait for the link-local addresses to
resolve. Link-local addresses for the Primary Dante interfaces obtain IP addresses in the

169.254.xxx.xxx range, secondary Dante interfaces obtain addresses in the 172.31.xxx.xxx range.

User and Control Bit Pass-Through


To enable the pass-through of AES user and control bits the device must be set to 32-bit encoding
( PCM 32 ). This is set within the Encoding section of the Device Config tab.

Brooklyn Reset

Resetting the Dante Brooklyn card to default settings is performed from Dante Controller. Under the
Device Config tab for a device select Clear Config . This clears the device name, channel labels, IP
address settings, sample rate, latency and existing audio routes.

Clocking Scenarios

Network of Consoles With House Sync

This setup shows a network containing multiple consoles. Two are shown but the principles would
remain the same for a larger network. House synchronisation is provided to multiple MADI Bridge
devices, these are set to ‘Enable sync to external’ within Dante Controller. This provides the network
with redundant master clock sources referenced to the house synchronisation. One device would be
elected as the Grand Master Clock for the Dante network, if that were to fail another MADI Bridge
would take the role of Grand Master.



Clocking from the Network

In this example a MADI Bridge receives a redundant external sync signal. This MADI Bridge is set to
Sync to External within Dante Controller. The remaining MADI Bridges will derive their own clock
from the master device. This can be fed to external TDM devices using the MADI Bridge wordclock
outputs.
