About Lightpipe-Compatible Devices
Lightpipe is an industry standard, eight-channel
optical digital audio connection developed by
Alesis. Lightpipe is found on many devices, in-
cluding ADAT decks, modular digital
multitracks (MDMs), sound cards, standalone
A/D or D/A converters, and digital consoles.
Word Clock
The Word Clock In and Out ports let you con-
nect BNC cables to synchronize 003 and 003
Rack to incoming 1x Word clock, and synchro-
nize other devices to Pro Tools-generated Word
clock.
MIDI Connectors
The MIDI In and MIDI Out 1 and Out 2 ports are
standard 5-pin MIDI ports. The MIDI In port
supports 16 channels of MIDI input. Each MIDI
Out port supports 16 channels of MIDI output,
for a system total of 32 channels of MIDI output.
A MIDI driver for these MIDI ports is installed
when you install Pro Tools LE, and is recognized
automatically by MIDI Studio Setup (Windows)
and Audio MIDI Setup (Mac). These connectors
accept standard 5-pin MIDI cables.
Kensington Lock Port
Use the Kensington Lock port to secure your in-
terface with a Kensington Lock (not supplied).
For more information, visit the Kensington web-
site (www.kensington.com).
Footswitch Jack
This connector allows footswitch control of
QuickPunch audio punch-in and punch-out,
and MIDI punch-in and punch-out recording
features. The footswitch connector is designed
specifically for instantaneous (momentary)
on/off pedals with a 1/4-inch TRS connector.
Continuous on/continuous off pedals can also
be used, but may result in unexpected behavior.
IEEE-1394 (FireWire) Ports
These ports, marked “1394” in reference to their
IEEE specification, are commonly known as
FireWire ports. These provide connections to the
computer and other FireWire devices.
FireWire offers a high rate of data transfer and
reliability that makes it ideal for audio applica-
tions (such as Pro Tools with 003 or 003 Rack).
FireWire devices can be daisy-chained together
without the need for terminators.
If you are using a Windows laptop that has
a 4-pin FireWire port (commonly labeled
“1394”), see “4-Pin FireWire Cable” on
page 13 for FireWire cable information.
