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. The User bits are passed-through unchanged. More details can be found in chap-

ter 10.2.

10.2 AES-3id

The 32 AES-3id outputs are provided on the rear of the ADI-6432R BNC via 32 BNC connec-

tors. Every output is transformer-coupled but not ground-free. The BNC sockets are connected

to the housing (GND). 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

• Audio use, No Copyright, Copy permitted, Format Professional

• Category General, Generation not indicated

• 2-Channel, No Emphasis

• Aux Bits Audio use, 24 Bit

• Origin: 6432

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. The User bits are passed-through unchanged.

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.
