User`s guide
1. These jacks provide stereo, 24-bit AES/EBU digital input
and output at any sample rate up to 96kHz. They are
disabled at the 4x rates (176.4 and 192kHz).
2. Connect the Traveler to the computer here using the
standard 1394 FireWire A cable provided with your
Trav el er.
Important note: it is best to turn off the
Traveler when plugging in the FireWire cable, as this
avoids the possibility of static discharge, which can
harm the electrical components in the Traveler or
your computer.
Use the second FireWire port to daisy-
chain up to four MOTU FireWire audio interfaces to a
single FireWire bus. You can also connect other FireWire
devices. For details, see “Connecting multiple MOTU
FireWire interfaces” on page 37.
3. These are standard word clock jacks. Use them for a
variety of applications, such as for digital transfers with
devices that cannot slave to the clock supplied by their
digital I/O connection with the Traveler. When the
Trav el er is operating at a 2x sample rate (88.2 or 96 kHz)
or 4x sample rate (176.4 or 192kHz), the word clock
output can either match the Traveler’s sample rate or be
reduced to the equivalent 1x rate (either 44.1 or 48 kHz).
This setting is made via the FireWire Audio Console. See
“Word Out” on page 44.
4. These optical digital I/O connectors can be connected
either to an ADAT-compatible “lightpipe” device (such as
a digital mixer) or to a S/PDIF optical (“TOSLink”)
compatible device, such as an effects processor or DAT
machine. Be sure to set the format in the MOTU FireWire
Audio Console software. (see “Optical input/output” on
page 43) for details.) ADAT optical supplies eight
channels of 24-bit digital I/O (4 channels at 96kHz).
TOSLink is stereo. Note: you can choose independent
formats for the optical IN and OUT. For example, you
could choose ADAT for the optical IN (for, say, eight
channels of input from your digital mixer) and S/PDIF for
the optical OUT (for, say, your DAT machine).
5. If you are using the Traveler with an ADAT, use this
standard ADAT SYNC INPUT to connect the Traveler to the
end of your ADAT sync chain. For example, if you have
three ADATs, chain the ADATs in the usual fashion (SYNC
OUT to SYNC IN, etc.), and then connect the last ADAT’s
SYNC OUT to this SYNC IN. This connection allows you to
make sample-accurate audio transfers between
AudioDesk (or other sample-accurate software) and the
ADATs. If you have a MOTU MIDI Timepiece AV or Digital
Timepiece, make it the master of the ADAT SYNC chain so
that you can control everything from AudioDesk (or your
other MIDI Machine Control compatible software).
6. These jacks provide stereo, 24-bit S/PDIF digital input
and output at any sample rate up to 96kHz. They are
disabled at the 4x rates (176.4 and 192kHz).
7. The Traveler’s eight analog outputs are gold-plated,
balanced +4dB TRS (tip/ring/sleeve) quarter-inch
connectors that can also accept an unbalanced plug.
They are equipped with 24-bit, 128x oversampling
converters.
8. These two balanced, quarter-inch jacks serve as the
Trav el er’s main outputs. You can connect them to a set of
powered studio monitors and then control the volume
from the front panel volume knob. (Push the knob first to
switch to main out volume control.) To hear disk tracks in
your audio software on these main outs, assign the disk
tracks (and master fader) to these main outs
(Analog 1-2). You can also use CueMix DSP to monitor
live Traveler inputs here as well.
9. These 4 analog inputs are gold-plated, balanced TRS (tip/
ring/sleeve) quarter-inch connectors that can also
accept an unbalanced plug. The front panel LCD and
Cuemix Console software let you adjust them for either
+4dB or -10dB input signals. They have 24-bit, 64x
oversampling converters. These inputs (5 through 8) do
not have microphone preamps, so they are best used for
synthesizers, drum machines, effects processors, and
other instruments with line level signals.
10. These four Neutrik™ combo (XLR/TRS) jacks accept
either a mic cable or a cable with a quarter-inch plug.
Both the low-impedance XLR jack and the high-imped-
ance TRS jack are equipped with a 20dB pad (so you can
even connect a +4 line level input). 48V phantom power
can be supplied via the front-panel switch.
11. Connect a MIDI device here using standard MIDI cables.
Connect the Traveler’s MIDI OUT port to the MIDI IN port
on the other device. Conversely, connect the Traveler’s
MIDI IN port to the MIDI OUT port on the other device.
You can connect different devices to each port, such as a
controller device to the IN port and a sound module to
the OUT port. You can also daisy-chain MIDI devices, but
be sure to manage their MIDI channels (so that they
don’t receive or transmit on the same channel).
12. For bus-powered operation, turn on the Bus Power
Enable switch. For battery operation (i.e. powering the
Trav el er from a battery pack via the 4-in XLR jack), turn
this switch to the OFF position.
13. Connect a 10-24V battery pack or other power supply
here via a 4-in XLR cable. Remember to also turn off the
bus power switch to the left.
14. This jack accepts any standard 10-24V DC power supply
with either tip-positive or tip-negative polarity. Remem-
ber to also turn the BUS POWER switch to the OFF
position.
