1 Introduction
Thank you for purchasing the LT-FW™! We are proud to provide you with a reliable,
professional-quality product for your digital audio requirements.
This manual provides basic information to help you get started. Additional information is
available via our web site and email support. Please refer to Section 10, Support, at the end of
this manual for support contact information.
The LT-FW is an LSlot expansion interface that is designed to allow the Aurora professional
audio AD/DA converters to be used with IEEE-1394a FireWire equipped laptop and desktop
computers. The LT-FW can be used with Windows or Mac based systems, with a convenient
and easy-to-use software interface for setting parameters, managing volume levels, viewing
real-time meters, etc. Up to 32-channels of simultaneous I/O are possible with an Aurora 16,
and up to 16-channels with an Aurora 8.
1.1 Overview
The Aurora/LT-FW turns your computer into a powerful digital audio workstation, giving
you up to 16 channels of professional AES/EBU digital input and output and up to 16
channels of mastering quality analog inputs and outputs at sampling rates up to 192 kHz. The
included remote control application provides zero-latency monitoring, accurate metering,
adapter configuration and flexible routing capabilities. With support for WDM and ASIO on
Windows computers and Core Audio with OS X Macintosh computers, virtually all
professional audio applications can work with the LT-FW.
The LT-FW features two industry-standard IEEE-1394a FireWire ports, allowing up to two
LT-FW equipped Auroras to be daisy-chained off of a single FireWire connection.
Installation of the LT-FW into an Aurora is straightforward, as is the driver installation
routine (Please note that no driver install is required for OS X – native support is provided by
the operating system).
The Aurora Remote Control application includes an LT-FW control panel where important
parameters can be established, such as buffer size and channel mode. The LT-FW channel
modes allow different configurations of the interface, whereby I/O channel number and type
can be defined. This provides access to the physical I/O ports that are required, while
optimizing the amount of processing power that is required by the interface. For instance, an
Aurora 16 will consume less CPU power when used in an 8 or 16-channel configuration, as
opposed to a 32-channel configuration.

2 Before you begin
We recommend that you read through the entire manual to acquire an overview of the
installation procedure and use of the LT-FW. This manual will presume a working
knowledge of the Aurora converter. For additional information, please refer to the Aurora
User Manual.
It is also highly recommended that you have a good working knowledge of Windows and/or
Macintosh operating system basics and an understanding of computer hardware basics. This
information is widely available on the web and from various computer hardware and
software manufacturers.
We also strongly recommend you familiarize yourself with the basics of digital audio and
computer recording, and particularly with the basic functionality of your chosen audio
software. A solid grasp of the operational fundamentals of your Digital Audio Workstation
software and its user interface will go a long way toward enhancing your experience with the
LT-FW.

2.2 Operational requirements
There are three essential elements that must be met for compatibility with the LT-FW:
1. The host computer must have a compatible and functional FireWire interface.
2. The host computer must meet the system requirements necessary for correct functioning
of the LT-FW.
3. The Aurora must have firmware revision 18 or above.
It also is important to note that most professional audio applications place significant
demands on your computer’s resources, and it is therefore recommended that you meet or
exceed the recommended system requirements for your Digital Audio Workstation software,
which will likely be greater than those listed for the LT-FW. Please refer to your audio
software’s documentation for more information.
2.2.1 FireWire Chipsets
The Aurora/LT-FW can be used with most OHCI compliant FireWire adapters and integrated
FireWire ports on laptop and desktop computers. It is a FW400 (IEEE-1394a) device, but
FW800 (IEEE-1394b) interfaces should also work with the appropriate adapter cable, as
backwards compatibility is integral to the IEEE-1394b specification.
2.2.2 Windows
Pentium III class computer or better
64 MB RAM
One OHCI compliant FW400 (IEEE-1394a) or FW800 (IEEE-1394b) port
Video display with 1024 x 768 minimum resolution
Windows 2000, Windows XP (32-bit or 64-bit), Windows 2003 Server or Windows Vista
(32-bit or 64-bit)
NOTE: The LT-FW is not supported under Windows 95, 98 or ME.

2.2.3 Macintosh
Apple Macintosh G4 or later
64 MB RAM
One OHCI compliant FW400 (IEEE-1394a) or FW800 (IEEE-1394b) port
Video display with 1024 x 768 minimum resolution
Macintosh OS X (10.4 or higher)
NOTE: The LT-FW is not supported under OS 9.
2.2.4 Insuring compatible firmware on the Aurora
The LT-FW requires your Aurora converter to have Firmware Version 18 or later. This
should be verified prior to installing and configuring the LT-FW card. To determine what
firmware revision your Aurora has installed, press the TRIM and POWER buttons at the
same time with the power to the Aurora off. If the LED flashes over the numbers 1 on the
input row & 8 on the output row or above (i.e. 1&8, 1&9, etc.) in the Aurora Meter Display,
then your unit is compatible with the LT-FW. If pressing Power and Trim does not cause
any LEDs to flash, causes a sequence lower than 18 to flash, or causes a single number to
flash, then your unit needs to be updated.
Updating the Aurora firmware to version 18 may require a Lynx AES16 PCI audio interface.
If your Aurora has firmware version 13, it can also be updated by an Apple Macintosh
running OS X via MIDI, or by a PC running Windows via MIDI or IrDA. The Aurora
firmware updater program and instructions for use are available for download from the Lynx
website at Support > Latest Driver Download. If your unit requires an AES16 to update
because it has rev 12 or earlier, and you do not have access to one, there are two options for
customers within the USA and Canada:
• Option 1: Send the Aurora and LT-FW to Lynx Studio Technology in California. We will
update the Aurora, install the LT-FW and do a full diagnostic test within one day of
receipt. It will be return shipped via 2-Day Air.
• Option 2: Lynx Studio Technology will loan you an AES16 for updating the firmware in
your Aurora. For more information on the procedure and any questions, contact
If you are outside of the USA or Canada, please contact your local distributor for additional
firmware update options.

5 Installation Procedures
1. Remove the AC power cord and take the top cover off of the Aurora. There are seven
large screws plus one small screw near the center of the front faceplate that holds the top
cover on.
2. Before installing the LT-FW card, you must change a jumper setting on the Aurora that
corrects the current draw for an Aurora with an LT-FW.
If you are updating a Rev A. Aurora, remove jumper W3 from the JP6 header on the
Aurora main board.
If you are updating a Rev B Aurora, slide switch 4 (labeled W4 on PCB) of SW1 to the
OFF position (towards back panel).
3. Remove the LSlot Expansion Port cover above the AES I/O Ports by removing the two
mounting screws. Set these two screws aside, as they will be used to secure the LT-FW
after installation.

4. Remove the screw from the Aurora circuit board that is adjacent to the JP1 connector and
the white serial number/barcode label. Set the screw aside for reuse.
5. Install the standoff post (included with the LT-FW) in this same hole.
6. Grounding yourself to earth ground, remove the LT-FW from its protective static bag.

7. Attach the multi-pin connector on the back edge of the LT-FW to the LSlot connector
(JP1) on the Aurora main board. When the LT-FW connector pins appear to be lined up
correctly with the Aurora LSlot connector, press gently until the connector snaps into
place. In some cases, the board may need to be gently flexed for the LSlot connector pins
to line up correctly with JP1 on the Aurora main board.
Use caution to insure that the pins line up as shown.
Incorrect installation could damage the unit.
8. Secure the LT-FW with three screws; one on the standoff and two from the back panel of
Aurora. Keep screws loose until the LT-FW is properly aligned, then tighten snugly, but
do not over tighten.
