CHAPTER 1: Overview
CHAPTER 1: Overview
Introduction
The MADI.SRC enables real time sample rate conversion of a complete MADI
stream. It includes 32 high quality stereo sample rate converters, and supports all
source and destination sample rates from30 kHz to 50 kHzand their multiples, for
all MADI formats (48k/96k Frame, 56/64 channels, S/MUX).
With one RU height, two redundant power supplies and excellent sounding sample
rate converters the device offers best and reliable audio quality at a minimal need
of rackspace.
Feature Summary

1 x coaxial BNC connector, 75 Ω (BNC/SC)
or
2 x SC-Socket multi/single-mode (SC/SC)
MADI Formats 56/64 channel, 48k/96k Frame, S/MUX 2/4
Sample Rates 32 kHz to 50 kHz and their multiples

coaxial BNC, 75 Ω termination switchable
This input also accepts an AES3 frame (AES11).
1 x Video
coaxial BNC, 75 Ω termination switchable,
black burst (PAL, NTSC)
Operating Modes Normal Mode: one input active, outputs parallel
Split Mode: inputs and outputs combined
USB Port USB 2.0 port for firmware updates

supplies (84 V to 264 V AC / 47 Hz to 63 Hz / safety
class 1)

MADI.SRC Manual - Version 2.0
CHAPTER 1: Overview
How it works
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 output format
(56/64ch, 48k/96kFrame of the MADI input signal can be also modified with the
SRCs switched off.
By activating theSplit Mode, the inputs and outputs can be used in combination to
make use of all 32 stereo SRCs at higher sample rates. Depending on the SRC's
setting this allows for conversion of more than 32 (@96 kHz) or 16 (@192 kHz)
channels.
Applications
The MADI.SRC is designed for use in environments where the highest possible
quality sample rate conversion is at a premium. The stream is processed in real
time and all output channels are phase and sample accurate to each other.
Further the MADI.SRC can be used as a decoupling device to connect two
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 (e.g. 2 x 32 channels @ 96 kHz into 1 x 64 channels @ 48 kHz).
• Format conversion of signals (e.g. 48k Frame S/MUX into 96kFrame).
• ...

CHAPTER 2: Legal issues & facts
First Aid (in case of electric shock)
WARNING!
• Do not touch the person or his/her clothing before power is turned off,
otherwise you risk sustaining an electric shock yourself.
• Separate the person as quickly as possible from the electric power source
as follows:
- Switch off the equipment.
- Unplug or disconnect the mains cable.
• Move the person away from the power source by using dry insulating
material (such as wood or plastic).
• If the person is unconscious:
- Check their pulse and reanimate if their respiration is poor.
- Lay the body down and turn it to one side. Call for a doctor immediately.
• Having sustained an electric shock, always consult a doctor.

Chapter 4: Operation
Introduction
This chapter describes the basic operation of the device.
Note that throughout this manual, the abbreviation FS refers to sample 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
