CHAPTER 1: Overview
CHAPTER 1: Overview
Introduction
MADI.9648 is a synchronous MADI sample rate converter with four independent
SRC blocks for bidirectional conversion of 128 audio channels. Equipped with eight
MADI ports it features synchronous low latency conversion in a ratio of exactly 1:2
or 2:1 to translate between 2 FS (88.2/96 kHz) and 1 FS (44.1/48 kHz).
Feature Summary
MADI Ports 2 x SC multi-mode connectors
6 x coaxial BNC connectors
MADI Formats 56/64 channel, 48k/96k Frame
Sample Rates 44.1, 48, 88.2, 96 +/-12.5%
Sample Rate Conversion 128 audio channels, bidirectional
Low Latency 8 samples (round-trip 48-96-48)
16 samples (round-trip 96-48-96)
USB Port USB 2.0 port for firmware updates.
Power Supply This device is equipped with two wide range power
supplies (84 V to 264 V AC / 47 Hz to 63 Hz / safety
class 1)
How it works
A 1 FS MADI stream with 64 audio channels is converted into two 2 FS MADI
streams with 32 channels each of. Vice versa two 2 FS streams are converted and
combined into a single 1 FS stream.
MADI.9648 provides:
• 2 x conversion from 1 FS to 2 FS
• 2 x conversion from 2 FS to 1 FS
No settings are required:
• Fixed signal routing
• Automatic signal detection of frame format (48k/96k Frame)
and channel mode (56/64 ch).
• Frame format of 2 FS output is set following the input of the same port
• The output of each SRC block is clocked by it’s corresponding MADI input.

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
The display indicates that a working power supply is connected to the power
supply unit. Note that an unlit display does not guarantee that the device is free of
voltage. To ensure that the device is completely disconnected from mains voltage,
the power chord(s) must be disconnected.
CHAPTER 4: Operation

CHAPTER 4: Operation
* port 1 & 3 are used as clock master and define the channel mode for its
particular block.
** port 7 respective port 8 is selected as clock and input source, if both inputs of
the particular SRC block detect a valid signal.
NOTE
Mixed conversion of 28 ch and 32 ch is not possible. Either 2 x 28 ch or 2 x 32 ch.
The signal routing and the sample rate conversion is fixed for each signal path.
SRC mode UP means from 1 FS to 2 FS, while DOWN means from 2 FS to 1 FS.
• UP : one stream is distributed into two streams
• DOWN : two streams are combined into one stream

CHAPTER 4: Operation
Sample Rate Conversion
There are two SRC Groups featuring each of an 1 FS to 2 FS block and vice versa
a 2 FS to 1 FS block. Each block provides LEDs monitoring for input sync, sample
rate and signal format.
2 FS
SYNC (1, 2, 3, 4)
LED (green) indicates the lock / sync state of
the MADI input signal
ON = signal present, in sync
blinking = signal present, not in sync*
OFF = no signal detected
2 FS
SR (96)
LED (yellow) indicates the sample rate
96kHz of the input signal
ON = 96 kHz detected
blinking = 96 kHz detected, S/MUX
2 FS
SR (88.2)
LED (yellow) indicates the sample rate
88.2kHz of the input signal
ON = 88.2 kHz detected
blinking = 88.2 kHz detected, S/MUX
2 FS
FORMAT (32ch)
LED (green) indicates the use of channel
mode 32 ch in the input signal
ON = 32 ch detected
blinking = 32 ch detected, S/MUX
2 FS
FORMAT (28ch)
LED (green) indicates the use of channel
mode 28 ch in the input signal
ON = 28 ch detected
blinking = 28 ch detected, S/MUX
* port 1 & 3 are used as clock master and define the channel mode for its
particular block.
NOTE
The 2 FS inputs accept both 96k Frame and 48k Frame (S/MUX). The 2 FS outputs
are set to 96k frame or 48k frame (S/MUX) following the input of the same port.
The output of each SRC block is clocked by it’s corresponding MADI input.
Synchronous conversion in a ratio of exactly 1:2 or 2:1 to translate between 2 FS
(88.2/96 kHz) and 1 FS (44.1/48 kHz).
