INSTALLING THE 896HD HARDWARE
22
SAMPLE-ACCURATE ADAT SYNC
The 896HD 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 Mac OS 9 ASIO 2.0-compatible
software that also supports sample-accurate sync.
Connect the 896HD to the end of the ADAT Sync
chain and make the software settings shown below
in Figure 3-10. 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 25.
Digital Timepiece, MIDI Timepiece AV,
Alesis BRC or any other MMC-compatible
ADAT synchronizer
Macintosh computer running AudioDesk, Digital
Performer or other sample-accurate software.
USB or serial cable (bi-directional MIDI
connection) bearing MMC transport
commands from AudioDesk or
Digital Performer to the
MIDI Timepiece AV (or other synchronizer)

To set the 896HD hardware clock source for sample-accurate sync:
1. In AudioDesk or Digital Performer, choose MOTU Audio
System>Configure Hardware Driver from the Setup menu (or
the Basics menu under OS 9), or run the MOTU FireWire Audio
Console.
2. Choose ADAT 9-pin from the Clock Source menu as shown to
above.
3. Make sure the Sample Rate setting matches the recorder and
synchronizer.
In AudioDesk or Digital
Performer, turn on MIDI
Machine Control by pressing
this button. This brings on line
all the recorders connected to
the DTP or MTP AV.
AudioDesk automatically scans
the DTP or MTP AV for
connected recorders, and they
appear here.
If you have a MOTU
synchronizer, set its
sync mode to Internal.
For sample-accurate sync settings in Cubase, see “Sample-
accurate sync to ADAT or Tascam” on page 83.

Use this setup if you have:
✓
ADATs, Alesis hard disk recorders or any ADAT SYNC
compatible device(s).
✓A MOTU Digital Timepiece, MIDI Timepiece AV or other
ADAT synchronizer.
✓Host software that supports sample-accurate sync.
This setup provides:
✓
Sample-accurate locating between all ADAT SYNC-compati-
ble devices, the 896HD and your software (AudioDesk,
Digital Performer or other sample-accurate software).
✓With a Digital Timepiece, this setup provides sample-accurate
locating across all devices: ADAT, Tascam and the 896HD.
✓Transport control of everything from the computer, OR
continuous sync to SMPTE time code and other sync sources
