Sample-Accurate Adat Sync - MOTU Traveler User Manual

SAMPLE-ACCURATE ADAT SYNC

The Traveler can achieve sample-accurate sync
with ADATs, Alesis hard disk recorders or any
ADAT Sync-compatible devices. Sample-accurate
software is required, such as AudioDesk, Digital
Performer or compatible software that also
supports sample-accurate sync. Connect the
Traveler to the end of the ADAT Sync chain and
make the software settings shown below in
Figure 3-14. If you will be using the stand-alone
recorder for its analog inputs and outputs only
(you won't be doing any recording with it), treat it
as an 'optical' device. See "Syncing optical devices"
on page 32.
