SAMPLE-ACCURATE ADAT SYNC
This page shows an ideal setup for using the
PCI-424 and a 2408mk3 interface with one or more
ADATs, Alesis hard disk recorders or any ADAT
SYNC-compatible devices. Connect the PCI-424
card to the end of the ADAT chain and make the
software settings as shown below in Figure 3-20.
This setup is also ideal if you have both Alesis and
Tascam decks. If so, connect your Tascam
equipment to the Digital Timepiece as directed in
the Digital Timepiece manual.
☛ For ADAT optical digital mixers, see “Syncing
ADAT ‘lightpipe’ devices” on page 46.
