Alesis BRC - B Connecting the AI-1

to the second ADAT’s optical in jack. Its optical out jack then
connects to the third ADAT’s optical in jack, and so on;
4. Finally, connect one end of a fiber optic cable to the last ADAT’s
optical out jack, and the other end to the first ADAT’s optical in
jack. This last step creates a loop, and thus makes the digital bus
accessible to all ADATs that are connected to it.
Note: Always connect the optical cables in the same order as the sync
cables, so that the digital routing will work correctly.
2.2B Connecting the AI-1
To connect an Alesis AI-1 module, simply insert it into the digital bus
loop that was described above in 2.2A, at the end of the ADAT chain.
You must also connect the sync cables so that the AI-1 is inserted
between the BRC and the first ADAT in your system (see figure 2).
1. Connect one end of the fiber optic cable into the optical output of
the last ADAT in the system;
2. Connect the other end of the fiber optic cable to the ADAT optical
input of the first AI-1 in the system;
3. Connect one end of a fiber optic cable to the AI-1’s ADAT optical
out jack, and the other end to the first ADAT’s optical in jack. This
step creates a loop, and thus makes the digital bus accessible to all
ADATs and all AI-1 modules connected to it;
4. Finally, connect one end of a dual male, 9-pin D connector to the
BRC’s sync out jack, and the other end to the AI-1’s sync in jack.
The AI-1’s sync out jack must then be connected to the sync in jack
of the first ADAT in your system;
