The two rear panel DB-9 connectors marked SYNC IN and SYNC OUT synchronize
two or more ADAT-family devices, such as the LX20, XT20, M20, original ADAT,
ADAT-XT, and/or a computer hard disk audio recording/editing system using the
ADAT-PCR sound card or similar device.
Synchronization requires a male-to-male, 9-pin D connector cable for each
additional machine in the chain. These cables are available in various lengths
from Alesis or your dealer and should be Alesis-approved; improper cables (such as
those used for computers) may not function correctly.
In such a system, you are basically treating all connected machines as though they
were a large multitrack unit. The first LX20 or ADAT in the chain is the "master,"
and all other connected units are called "slaves." However, each slave can also be
used independently when the master machine is stopped.
For details about using multiple LX20s and/or ADATs, refer to Chapter 10.
To synchronize multiple LX20s 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 shows two LX20s synchronized together.
