CHAPTER 1: Overview
Introduction
Welcome to the MADI.SRC, DirectOut’s purpose designed solution
for real-time sample rate conversion of a MADI signal:
The MADI.SRC enables real time sample rate conversion of a complete MADI stream (64 audio channels). The device includes 32
high quality stereo sample rate converters (SRCs), and supports all
source and destination sample rates from 44.1 kHz to 192 kHz, for
all MADI formats (48k/96k Frame, 56/64 channels, S/MUX).
Two pairs of MADI inputs and outputs are provided on optical connectors (SC multi-mode) and coaxial connectors (BNC). In normal
mode, one of the inputs is active, with both outputs carrying the
converted input signal.
By activating the innovative Split Mode, inputs and outputs can
be used in combination to convert more than 32 (@ 96 kHz) or
16 (@ 192 kHz) channels, depending on the SRC setting.
Synchronisation may be achieved via word clock or AES3id (AES11),
Video Reference (PAL/NTSC), the MADI input signal, or using the
internal clock.
The device includes two phase-redundant power supplies; power
inlets and switches are located on the rear panel. The unit also features a USB port, which can be used for remote control via Windows
software.
Note that the MADI input and output can be converted from optical to coaxial, or vice versa, using the SPLIT.CONVERTER. Please
visit the DirectOut website at www.directout.eu for further details on
this product.

CHAPTER 1: Overview
© 2014 DirectOut GmbH
Applications
The MADI.SRC may be used wherever high quality sample rate
conversion is required. The data stream is processed in real time
and all output channels are phase and sample accurate with reference to each other.
Because of its comprehensive features, the device can also be used
beyond ‘simple’ sample rate conversion. For example, if two digital
systems cannot use the same word clock source, the MADI.SRC
can be used as a decoupling device to connect both asynchronous
systems without any loss of audio quality.
With the SRC switched off, the device works as a simple format
converter, and provides different MADI formats at the output ports
(48k/96k Frame, 56/64 channel).
Typical applications include:
• Broadcast environments using different clock masters.
• Dubbing of multichannel signals for archiving
• Combination of two high sample rate streams to a single lower
sample rate stream (For example: 2 x 32 channels @ 96 kHz
=> 1 x 64 channels @ 48 kHz).
• Format conversion of signals (e.g. 48k Frame S/MUX <=>
96k Frame).
How it Works
The MADI.SRC provides sample rate conversion and conversion of
MADI signals as follows:
The MADI input signal is buffered and routed via the sample rate
converters (32 stereo SRCs) to the output. The output signal is
reclocked by the selected reference (internal, MADI, Video, word
clock or AES3id). The format (56 channel or 64 channel, 48k Frame
or 96k Frame) of the MADI input signal can be also modified with
the SRCs switched off.
In Split Mode, the MADI inputs and outputs are combined in order to
optimise the SRCs available. According to the settings of the SRC it
is possible to convert more than 32 (@ 96 kHz) or 16 (@ 192 kHz)
channels.

Introduction
This chapter describes the basic operation of the device.
Note that throughout this manual, the abbreviation FS refers to sam-
ple rate or sample frequency. So, when dealing with scaling factors,
the following sample rates can be written as:
• 44.1 kHz or 48 kHz = 1 FS
• 88.2 kHz or 96 kHz = 2 FS
• 176.4 kHz or 192 kHz = 4 FS
The green LEDs (PSU 1 & PSU 2) indicate that a working power
supply is connected to the power supply unit. Note that an unlit LED
does not guarantee that the device is free of voltage. To ensure
that the device is completely disconnected from mains voltage, the
power chords must be disconnected.
MADI IN
These controls select the operating mode and MADI input, and indicate the sample rate and format of the MADI input signal. Two MADI
inputs and two operating modes are provided:
• In Normal Mode either MADI input may be selected.
• In Split Mode both MADI inputs can be used depending on the
combination of the input and output SRC selections.
SPLIT I/O LED (yellow): indicates
the operating mode:
LED OFF = Normal mode active
LED ON = Split Mode active
Press and hold the MADI IN button
(for more than 2 seconds) to
change the operating mode.
1 or 2
(Input Select)
2 LEDs (green): indicate the
selected MADI input.
In Normal Mode, press the MADI IN
button quickly to select an input (1 or 2).
LED OFF = input is not selected
LED ON = input is selected
LED blinking fast = no signal detected
Note that in Split Mode, both LEDs may
be lit (see „Split Mode“ on page 28).
See „Appendix A: Clocking to
MADI“ on page 36.
44.1 k or 48 k 2 LEDs (green): Indicate the sample
rate (base rate) of the MADI input.
The sample rate of the MADI input is
detected automatically and indicated
by either LED. Higher sample rates are
represented as a multiple of the base rate.
For example, if the input sample rate is
96 kHz (2 FS), then the 48 k LED is lit.
DirectOut Technologies

56CH or 64CH 2 LEDs (green): Indicate the channel
format (at base rate) of the MADI input.
The channel format of the MADI input is
detected automatically and indicated by
either LED. At higher sample rates, the
number of available channels is reduced:
28 or 32 at 2 FS; 14 or 16 at 4 FS.
48kFr or 96kFr 2 LEDs (green/yellow): Indicate the
frame format of the MADI input.
The frame format of the MADI input is
detected automatically and indicated
by the 48k Frame LED (green)
or 96k Frame LED (yellow).
SYNC
LED (green): indicates the sync state of
selected input (SRC OFF) or indicates
Sync to unselected MADI input:
LED OFF = no lock
LED ON = selected input signal is in
sync with chosen clock reference.
LED blinking fast = selected input signal
is not in sync with chosen clock reference
(SRC OFF). (In Split Mode, a ashing
led indicates that MADI inputs 1 and
2 are not in sync with each other.)
See „Appendix A: Clocking to
MADI“ on page 36.

SRC
Sample rate conversion is needed when:
• A signal shall be translated to a different sample rate.
• Two devices require their own independent clock source
(clock isolation).
The SRC controls define the scaling factor of input and output sample rate, and switch the SRCs in or out of circuit.
1 FS, 2 FS or 4 FS
(Input Scaling
Factor)
Button: Selects the scaling factor
for the input sample rate.
The sub code of a MADI signal does not
transmit the scaling factor of the sample
rate reliably, and therefore it must be
selected manually.
Press the button to select the correct
scaling factor for the input signal; the
LED lights accordingly: 1 FS (green),
2 FS (yellow) or 4 FS (white).
Note that the 96k Frame format denes
a 2 FS signal; if the scaling factor does
not match, then the 2 FS LED ashes.
OFF
(SRC ON / OFF)
Button: Turns sample rate conversion
on or off, or toggles bypass mode.
Press short to toggle the SRCs on or off.
Press longer than 2 seconds
to toggle bypass mode.
OFF
(SRC ON / OFF)
LED (red): indicates the activation state
of the SRCs and the bypass mode:
LED OFF = sample rate conversion active
LED ON = sample rate conversion
inactive, normal bypass active
LED blinking = sample rate conversion
inactive, true MADI bypass active
1 FS, 2 FS or 4 FS
(Output Scaling
Factor)
Button: Selects the scaling factor
for the output sample rate.
Press the button to cycle through the output
options; the LED lights accordingly: 1 FS
(green), 2 FS (yellow) or 4 FS (white).
Also note that if the Auto Clock Range
Select option is active, the scaling
factor will follow the word clock or
AES3id signal (see page 29).
DirectOut Technologies

page 19 of 40MADI.SRC Manual - Version 1.4
Chapter 3: Operation
© 2014 DirectOut GmbH
When the SRCs are switched off (SRC OFF), the input signal is
processed transparently (the input signal is buffered and refreshed).
Two bypass modes:
a) Normal - no sample rate conversion is applied, the signal
is refreshed/reclocked, but sync settings are relevant.
b) True - no sample rate conversion is applied, only the
MADI carrier is refreshed, the data format remains unchanged. Sync settings are irrelevant.
Bypass mode ‘Normal’ still allows for format conversion:
48k Frame <=> 96k Frame, or 56 ch <=> 64 ch.
Pushing the SRC OFF button for more than 2 s toggles between
‘True MADI Bypass’ and ‘Normal Bypass’ or SRC operation.
Check the sync status of the MADI input and clock reference using
the SYNC LED as described in chapter „MADI IN“ on page 17.
The SRC processing delay amounts to about 2.5 ms. The delay
is equal for every channel; there is no change in phase between
channels.

Chapter 4: Operating Modes
Introduction
The MADI.SRC provides two operating modes:
• In Normal Mode one input is used and both outputs operate

• In Split Mode both inputs and outputs are combined in order to
take optimal advantage of the SRCs available.
This chapter describes each mode in detail.

Normal Mode
In Normal Mode only one MADI input can be used at a time and both
outputs transmit identical signals in parallel.
The MADI.SRC automatically detects the sample rate (base rate)
and frame format of the MADI input signal.
The detected base rate may then be multiplied by a scaling factor of
1, 2 or 4 resulting in the following sample rates:
• 44.1 kHz (1 FS), 88.2 kHz (2 FS), 176.4 kHz (4 FS)
or
• 48 kHz (1 FS), 96 kHz (2 FS), 192 kHz (4 FS)
As a MADI signal is limited in bandwidth to a maximum of 64 channels at 48 kHz, the number of available channels is governed by the
chosen scaling factor:
• 64 channels at 1 FS
• 32 channels at 2 FS
• 16 channels at 4 FS

Split Mode
The number of available channels in a MADI frame is 64 channels
at 1 FS; 32 channels at 2 FS or 16 channels at 4 FS. The MADI.
SRC provides 64 SRC channels independent of the selected FS,
optimising the device for higher sample rates.
In Split Mode both MADI inputs may be used to feed the SRC channels. Depending on the combination of input and output FS scaling
factors, the MADI outputs may transmit different signals in order to
output all available SRC channels.
All the possible combinations are listed below:

* Combines channels 01-32 of both inputs into one stream. To combine without SRC processing, deactivate SRCs (SRC OFF).
Once there are more input channels than output channels, one of
the MADI inputs must be selected (e.g. 1 FS to 2 FS, 1 FS to 4 FS,
2 FS to 4 FS).
If both inputs are available and input 2 is fed, then the mapping of
the output 2 channels is unaffected (e.g. 2 FS to 1 FS: at output
2, channels 01-32 are empty (Input 1) and channels 33-64 active
(Input 2).

Auto Clock Range Select (ACRS)
Normally, the scaling factor of the base sample rate (1 FS, 2 FS or
4 FS) is defined manually for input and output from the SRC controls. However, the MADI.SRC offers an option to switch the output
scaling factor automatically – Auto Clock Range Select (ACRS).
The input frequency of the word clock (or AES3id) signal is detected
automatically. When the option is active, the scaling factor for the
output (1 FS, 2 FS or 4 FS) follows a change in this frequency.
The following example illustrates ACRS when the selected clock
reference is WCLK:
• word clock input = 48 kHz, MADI output is set to 1 FS
• word clock input = 96 kHz, MADI output changes to 2 FS
To activate the ACRS option:
1. Switch on the MADI.SRC device.
Initially all the LEDs on the front panel illuminate. After about
2 seconds, only a few LEDs are lit (indicating the rmware
revision of the device).
2. At this point, press the SRC output select button shown be-
low.
This turns the ACRS mode on or off.
The status is indicated by the SRC output LEDs as follows:
• All three LEDs lit = ACRS on
• No LEDs lit = ACRS off

Chapter 5: Application Examples
Introduction
This chapter describes how the MADI.SRC device can be used.
Example 1: Independent Clock Sources
At a music festival, the OB Van (recording) and FOH (Front of
House) require independent clock references such that the FOH
can use a “closed” system, while the OB Van locks to its word clock
reference.
The OB Van receives a MADI signal from the FOH after the signal has been re-clocked to its own word clock reference using the
MADI.SRC:
signal from stage
word clock
reclocked signal
to OB van

Example 2: Archiving / Remixing
In this studio example, we are playing back 48 channels recorded
at 48 kHz from a DASH machine and remixing on a digital console
running at 96 kHz.
The coaxial output of the DASH machine feeds into input 2 of the
MADI.SRC.
The MADI.SRC is set to operate in Split Mode, with MADI input 2
selected. This allows two MADI signals to be processed, expanding
the bandwidth by a factor of two.
Output 2 of the MADI.SRC feeds into SPLIT.CONVERTER in order
to convert from coaxial to an optical signal. (Note that no latency is
introduced in this process).
48 (64) channels at 1 FS are up-sampled to 96 kHz (2 FS) and are
then transmitted via both outputs of the MADI.SRC.
Two optical MADI signals at 96 kHz are provided to the mixing console:
48 (64) channels
MADI @ 96 kHz
Mixing Desk
1x 48 (64) channels

Appendix A: Clocking to MADI
The following overview helps exploring the meaning of the blinking
codes of the leds <SYNC>, <MADI IN> and <MADI OUT> when
clocking to MADI.
To toggle the clock source between selected and unselected MADI
input press the button <44.1k / 48k> in the MADI OUT section.
Don’t worry about the tables - they are quite similar and differ only
in the MADI OUT section.
