two or more HD24s together, or a combination of
HD24s and other ADATs, or a computer
workstation using the ADAT/EDIT card or similar
device. Up to five HD24s can be linked, making a
120-track system. This requires a male-to-male, 9-
pin D connector cable for each additional machine
in the chain.
Use only Alesis-approved Sync cables, available in
various lengths from your dealer. Improper

computers)
correctly.
In such a system, you are basically treating all
connected machines as though they were a large
multitrack unit. The first 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.
The Sync In and Out connections can also be used
for synchronizing to SMPTE Time Code.

drives, or ejecting tapes).
