Thanks to a highly sensitive input stage, SPDIF
signals can also be processed by using a sim-
ple cable adapter phono/XLR. To achieve this,
pins 2 and 3 of a male XLR plug are connected
individually to the two pins of a phono plug.
The cable shielding is only connected to pin 1
of the XLR - not to the phono plug.
10. Outputs
10.1 MADI
At the rear side of the ADI-6432 there are two MADI outputs. The BNC output is built according
to AES10-1991. The output's impedance is 75 Ohm. The output voltage will be 600 mVpp when
terminated with 75 Ohm.
The optical output uses a FDDI (ISO/IEC 9413-3) compatible optical module, according to
AES10-1991. More information can be found in chapter 15.4, MADI Basics.
Basically the MADI signal includes up to 64 channels in AES format, and therefore also the
according number of Channel Status data. For the ADI-6432’s output these are predefined.
Instead of the predefined data it is also possible to output the ones of the AES input channels.
The
AES Transparent Mode uses the Channel Status data of the uneven AES input channels
for the corresponding left and right MADI output channel. The data of the right input channels
are ignored. More details can be found in chapter 10.2.
10.2 AES/EBU
The 32 AES/EBU outputs are provided on the rear of the ADI-6432 via eight 25 pin D-sub con-
nectors with Tascam pinout (also used by Digidesign). A digital breakout cable will provide 4
male (and 4 female) XLR connectors per D-sub connector. Every output is transformer-
balanced, ground-free and compatible to all devices with AES/EBU ports. The output’s channel
status coding has been implemented according to AES3-1992 Amendment 4:
•
32 kHz, 44.1 kHz, 48 kHz, 64 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz according to the
current sample rate

Instead of this predefined coding it is also possible to output the data of the MADI input chan-
nels. The
AES Transparent Mode uses the Channel Status Data of the uneven MADI input
channels for the corresponding AES stereo output. The data of the right input channels are
ignored.
Note: In this mode the function
MIDI/Serial/Remote via MADI is deactivated. The device can still
be remote controlled via the DIN jacks.
Activation of the AES Transparent mode: during power-on press and hold the button CLOCK
AES – the CLOCK AES LED lights up. Deactivation: during power-on press and hold the button
REMOTE – the REMOTE DIN LED lights up.
The currently active mode is shown during display of the firmware version (after switching on
the unit) by the LEDs mentioned above.
