INSTALLING THE PCI-424 HARDWARE
41
SAMPLE-ACCURATE ADAT SYNC WITH NO
SYNCHRONIZER
Even if you don’t have an ADAT synchronizer, you
can achieve sample-accurate sync between ADAT
SYNC-compatible devices, a 2408mk3, and
sample-accurate software. Just connect the
PCI-424 card to the end of the ADAT sync chain as
shown below. But without the synchronizer, you
don’t get transport control from your computer,
nor can you slave the system to external SMPTE
time code. Instead, you have to play, stop, rewind
and cue the system from the transports on your
ADAT-compatible recorder.
Figure 4-21: Sample-accurate sync between Cubase (or other sample-accurate ASIO 2-compatible
host) and one or more ADAT SYNC-compatible devices—without an ADAT synchronizer.

1. In the MOTU PCI Audio Console, choose PCI-424: ADAT from the Clock
Source menu as shown to above.
2. Make sure the Sample Rate setting matches the other recorders.
Put Cubase into external sync mode.
See “Sample-accurate sync with Cubase or
Nuendo” on page 80 for more information.
In Cubase VST, go to the Synchronization window and
choose ASIO 2.0 as the Timecode Base. In Cubase SX, go to
the Synchronization Setup window and choose the ASIO

ADATs, Alesis hard disk recorders or any ADAT SYNC
compatible device(s).
✗ No ADAT synchronizer.
✓ Host software that supports sample-accurate sync.
This setup provides:
✓
Sample-accurate locating between all ADAT SYNC-compati-
ble devices, the 2408mk3 and your software (Cubase or other
sample-accurate software).
✗ No sync with Tascam recorders.
✗ No transport control of everything from the computer.
✗ No sync to SMPTE time code or other sync sources.
