MADI Terminal 1-1
Chapter
CHAPTER 1 MADI Terminal
General
The MADI Terminal is a 2RU chassis that has two primary functions, it converts AES or analog
audio into a Multichannel Audio Digital Interface (MADI/AES10) and it converts Multichannel
Audio Digital Interface into AES or analog audio. The MADI supports 32 pairs of 48 kHz digital
audio. This unit is capable of reporting signal information and errors via an Ethernet port or
serial port.
The chassis is made up of up to two power supplies, a controller board and two MADI bays.
The system usually arrives with a single power supply unless a redundant one has been
ordered. The controller board carries a CPU board and Timebase module that enable external
communication and distribute clocks for DARS timing of audio signals. Each MADI bays
consist of 3 audio I/O boards and a single MADI I/O board. The bays will be configured as
MADI inputs or outputs and will mate up with their corresponding AES or analog audio boards.
Figure 1-1. Chassis overview
Note: The above illustration contains the AES Unbalanced view. AES Balanced and
analog configurations will contain different rear panel layouts.

1-2 MADI Terminal
The audio signals that make up the MADI streams will come from or be delivered to the
input and output connectors as AES or analog signals. The MADI Output board receives
32 AES pairs that are individually analyzed and synchronized to the digital audio reference
(DARS) and are processed into a MADI Stream that is available at the BNC and Fiber
outputs. The MADI Input board receives a MADI signal from either the BNC or Fiber input
and extracts the 32 AES3 digital audio signals and distributes them to the audio outputs.
In a MADI output configuration there will be three audio input boards and a MADI output
board. In a MADI input configuration there will be a MADI input board and three audio
output boards. These input and output boards each have the capability interfacing to 11
audio signals but because of connector sizes and only needing a total of 32 signals
(3x11=33), some configurations will only use 10 of the 11 signal paths. Below you will find
a detailed explanation of the rear panels and their requirements.

MADI Terminal 1-3

System Setup Information
Unbalanced AES
Unbalanced AES Inputs and Outputs will have 10 signals per input or output board making up
30 of the 32 pairs used in a MADI stream. The last two signals come from or are delivered to
two BNCs located on the MADI board rear panel. In this configuration (unbalanced inputs) the
SW1 switch #4 should be toward the CFG B silkscreen (“ON” position) to indicate the onboard
AES input/output ports will be used for the last two signals.
Note: Cabling should always be completed from top to bottom, and right to left.
Figure 1-2. Unbalanced AES Inputs and Outputs

1-4 MADI Terminal
Balanced AES
Balanced AES Inputs and Outputs will have 10 signals at the first board and 11 signals on
the next two boards (10+11+11=32) making up 32 of the 32 pairs used in a MADI stream.
The last two signals come from the last two I/O boards. In the balanced inputs
configuration, the SW1 switch #4 should be toward the CFG A silkscreen (“OFF” position)
to indicate the AES signals come from the I/O boards and not the onboard ports. In the
D-SUB 37 drawing below, pins IOA10, IOB10 and IOC10 will be where signals 30 and 31
are on located in this balanced configuration.
Note:. Signal 30 will be the last signal on the second connector shown in the
illustration (I/O 2). Signal 31 will be the last signal on the third connector
displayed below (I/O 3).

Analog Audio
Analog audio Inputs and Outputs will have 10 signals at the first board and 11 signals on the
next two boards (10+11+11=32) making up 32 of the 32 pairs used in a MADI stream. The last
two signals come from the last two I/O boards. In the balanced inputs configuration, the SW1
switch #4 should be toward the CFG A silkscreen (“OFF” position) to indicate the AES signals
come from the I/O boards and not the onboard ports. The D-SUB 37 pin connector pinout is
the same as the AES pinout above. Below is the orientation of the left and right channels of
the analog audio connectors.
Note: Signal 30 will be the last signal on the second pair of connectors shown
in the illustration below (I/O 2). Signal 31 will be the last signal on the third pair
of connectors shown below labeled I/O 3.
