see “Making sync connections” on page 27. The
following sections briefly discuss each clock source
setting.
Internal
Use the Internal setting when you want the Traveler
to operate under its own digital audio clock. For
example, you may be in a situation where all you
are doing is playing tracks off hard disk in your
digital audio software on the computer. In a
situation like this, you most often don’t need to
reference an external clock of any kind.
Another example is transferring a mix to DAT. You
can operate the Traveler system on its internal
clock, and then slave the DAT deck to the Traveler
via the S/PDIF connection (usually DAT decks
slave to their S/DIF input when you choose the
S/PDIF input as their record source) or via the
Traveler’s word clo ck out put (if your DAT deck has
a word clock input).
If you would like help determining if this is the
proper clock setting for your situation, see “Do you
need a synchronizer?” on page 28.
With ADAT devices, however, you usually want an
external digital audio synchronizer, such as the
MIDI Timepiece AV or Digital Timepiece, to be the
digital clock master. In this case, you would set the
Traveler clo ck s ource setting to ADAT 9-pin, as
described below.
AES/EBU
The AES/EBU clock source setting refers to the
AES/EBU XLR input jack on the Traveler. This
setting allows the Traveler to slave to another
AES/EBU device.
Use this setting whenever you are recording input
from a DAT deck or other AES/EBU device into the
Traveler. It is not necessary in the opposite
direction (when you are transferring from the
Traveler to t he DAT machine).
For further details about this setting, see “Syncing
S/PDIF and AES/EBU devices” on page 35.
S/PDIF
The S/PDIF clock source setting refers to the
S/PDIF RCA input jack on the Traveler. This
setting allows the Traveler to slave to another
S/PDIF device.
Use this setting whenever you are recording input
from a DAT deck or other S/PDIF device into the
Traveler. It is not necessary in the opposite
direction (when you are transferring from the
Traveler to t he DAT machine).
For further details about this setting, see “Syncing
S/PDIF and AES/EBU devices” on page 35.
Wor d C l o c k I n
The Word C l o ck In setting refers to the Word Clock
In BNC connector on the Traveler rear panel.
Choosing this setting allows the Traveler to slave to
an external word clock source, such as the word
clock output from a digital mixer.
ADAT 9-pin
The ADAT 9-pin clock source setting refers to the
ADAT digital audio synchronization format. It
allows the Traveler to slave to an ADAT — or ADAT
sync chain — via its ADAT sync 9-pin connector.
ADAT sync also carries precise, sample location
information, which allows Cubase or other sample-
accurate ASIO 2.0-compatible audio software to
transfer audio to and from ADAT-sync compatible
recorders without drifting by as much as one
sample.
Use this setting when you are using the Traveler
with one or more ADAT-sy nc compatible
recorders. Make sure the Traveler i s connected to
the end of the ADAT sync chain.
