1. Introduction
With the ADI-6432 you have an incredibly versatile digital interface to your supply. From small
project studios to broadcast and television, this Advanced Digital Interface is the perfect solution for many tasks.
As a consequent continuation of RME's world-wide successful ADI series, the 6432 also contains elaborate technology and the latest integrated circuits. In a few words: The ADI-6432 is a
uniquely powerful and high-quality device, which will excite you even after many years of operation.
2. Package Contents
Please check that your ADI-6432 package contains each of the following:
• ADI-6432
• Manual
• Power cord
3. Brief Description and Characteristics
The ADI-6432 consists of two digital format converters in reference quality, in a standard 19"
box with 2 unit height. The compact device has numerous extraordinary features like Intelligent
Clock Control (ICC), SyncCheck
MADI, and remote control via MADI and MIDI.
All of the ADI-6432 I/Os support 192 kHz/24 bit. The format conversion between MADI and
AES/EBU operates in both directions at the same time. LEDs of different colours show the present state of incoming and outgoing signals and of the internal processing in a clear way.
The unique Intelligent Clock Control (ICC) allows for a flexible use with internal clock (44.1 up to
192 kHz), external word clock or the digital input signals. These options are intelligently coupled
in a way typical for RME, and easy to apply thanks to a clear and easily understandable display
of the Lock and Sync states.
The ADI-6432 transmits both MIDI and RS232 invisibly within the MADI data stream, maintaining full compatibility. The unit can also be remote controlled via MIDI.

4. First Usage – Quick Start
4.1 Controls and Connectors
The front of the ADI-6432 features nine buttons with 31 LEDs, and an extensive Status Display
including 97 more LEDs.
MADI INPUT determines the
current input for the MADI signal
(optical/coaxial). The state of the
input signal is shown in the STATE
section (ERROR, 64-channel
mode and 96k frame format) and
also in the big LED display in
detail.
AES INPUT displays the basic state of the AES input signal: ERROR, Double Speed and Quad
Speed. The big LED display, AES INPUT STATE, shows the presence of a valid input signal
separately for each AES input. RME's exclusive SyncCheck indicates via flashing LEDs if one
of these inputs is locked, but not synchronous to the chosen clock reference.
WORD INPUT displays the basic state of the word clock input signal: ERROR, Double Speed
and Quad Speed. Note that these LEDs are only active when word has been chosen as clock
reference.
In the CLOCK SECTION the current clock reference and frequency multiplier is chosen.
MADI OUTPUT is used to configure the MADI output as 56/64 channel or 48k/96k frame for-
mat.
REMOTE defines the source for MIDI remote control operation (MADI or DIN jack).
MIDI INPUT indicates received MIDI data from the 5-pin DIN input or the MADI input.
COM indicates serial data being received or transmitted via the COM connector.
LOCK KEYS allows to switch off all buttons. This way the ADI-6432 can be secured against
accidental operating errors.

The rear of the ADI-6432 provides the following connections: eight D-sub connectors (AES/EBU
I/O), two MADI optical, two MADI coaxial (BNC), two word clock (BNC), two MIDI (5-pin DIN),
one RS232 (D-Sub), and mains power.
MADI I/O optical: Standard MADI ports.
MADI I/O koaxial (BNC): Standard MADI ports.
AES I/O (25 pin D-sub): Each of the eight D-sub connectors provides four AES/EBU inputs and
outputs. The 25 pin D-sub connector is wired according to the widely spread Tascam standard
(pinout see chapter 14.7). The AES I/Os are transformer-coupled, high sensitivity type, therefore accept all common digital sources, even SPDIF.
WORD IN (BNC): A push switch allows to activate internal termination (75 Ohms).
WORD OUT (BNC): Standard word clock output.
MIDI I/O (5 pin DIN): MIDI input and output via 5-pin DIN jacks. Used for transmission of MIDI
data via MADI, and for remote control of the ADI-6432.
COM (9 pin D-sub): Serial interface for data transmission via MADI.
IEC receptacle for power connection. The specially developed, internal hi-performance switch
mode power supply makes the ADI-6432 operate in the range of 100V to 240V AC. It is shortcircuit-proof, has an integrated line-filter, is fully regulated against voltage fluctuations, and suppresses mains interference.

4.2 Quick Start
Configuration starts with choosing the MADI input, BNC or optical.
The state of the input signal is
displayed by a total of 38 LEDs.
Shown are active input, automatic
input selection, receiver state, Sync,
56 or 64 channel format, 48k frame
or 96k frame, and audio data on a
stereo basis. The Sync LED shows
the synchronicity between input
signal and external/internal clock, or
between the active inputs.
In the AES INPUT STATE section, each of the 32 inputs has its own SYNC LED. One LED per
(stereo) input indicates audio information within the data stream. An input signal in the range of
60 kHz to 100 kHz will turn the DS LED on. An input signal in the range of 162 kHz to 200 kHz
will turn the QS LED on.
The source and frequency of the unit's clock is configured in the CLOCK SECTION. The buttons CLOCK let you step through the options external clock (AES, MADI, word) and internal
clock (44.1 or 48 kHz). The button STATE sets the range for the internal, but also the external
sample rate. Selecting DS will result in 88.2 and 96 kHz, selecting QS sets 176.4 and 192 kHz.
The MADI output signal can include 56 or 64 channels (FORMAT). The FRAME button switches
the MADI output into native Double Speed mode (96K), in case internal or external clock allow
this mode to be activated.
The ADI-6432 can be remote controlled by MIDI commands. The button REMOTE is used to
select the source of the MIDI remote control commands, and also the destination for the ADI6432's request replies. The standard MIDI ports or the MADI input and output can be chosen.
LOCK KEYS allows to switch off all buttons. This way the ADI-6432 can be secured against
accidental operating errors.
The ADI-6432 remembers all settings before switching off, and sets them automatically when
switching on the next time.
