SYNC IN/OUT

The two DB 9 connectors marked [SYNC IN] and [SYNC OUT] are used for

synchronizing two or more XTs together, or a combination of XTs and ADATs. This

requires a male-to-male, 9-pin D connector cable for each additional machine in the

chain. In such a system, you are basically treating all connected machines as though

they were a large multitrack unit. The first XT or ADAT in the chain is called the

“master”, and all other connected units are referred to as “slaves”. However, each

slave can also be used independently when the master machine is stopped.

For more information about using multiple XTs and/or ADATs, refer to chapter 5.

To synchronize multiple XTs and/or ADATs:

¿Locate the [SYNC IN] and [SYNC OUT] connectors.

¡Connect one end of a male-to-male, 9 pin connector cable to the master’s [SYNC

OUT] jack.

¬Connect the other end of the cable to the first slave’s [SYNC IN] jack.

÷For additional slaves, connect one end of a male-to-male, 9 pin D connector

cable to the first slave’s [SYNC OUT] jack, and the other end to the second

slave’s [SYNC IN] jack. Its [SYNC OUT] jack then connects to the third slave’s

[SYNC IN] jack, and so on.

The following illustration depicts two XTs synchronized together.
