1 Introduction
Thank you for purchasing the LT-HD™! 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 the support section at the end of this
manual for support contact information.
The LT-HD is a 32-channel LSlot interface that is designed to allow the Aurora professional
audio AD/DA converters to be used with Digidesign® ProTools|HD® Recording Systems. The
LT-HD allows direct connection with ProTools|HD Core, Accel and Process cards. An LT-HD
equipped Aurora emulates a Digidesign 192 I/O™ interface, making integration simple and
allowing for accurate delay compensation within ProTools® software. Multiple LT-HD equipped
Auroras can be used to achieve the desired channel count within a ProTools|HD system.
2 Features
One Primary and one Expansion DigiLink port.
Up to 32 channels of AD/DA conversion per ProTools|HD Core or Accel/Process card
possible with two Aurora 16’s.
Aurora 16 can operate in 16-channel mode or 32-channel mode. In 16-channel mode up to 16
channels of analog and digital I/O can be used at one time. In 32-channel mode all 16
channels of analog I/O and all 16 channels of digital I/O can be used simultaneously.
Aurora 8 provides 8 channels of analog I/O and 8 channels of digital I/O simultaneously.
Supports full channel count at sample rates up to 192 kHz.
Offers audio signal latency identical to that of the Digidesign 192 I/O for accurate delay
compensation within ProTools - no manual delay adjustments required.
Allows I/O functions and Aurora parameters to be controlled and monitored within ProTools.
Interfaces with HD system using standard DigiLink cables.
Allows daisy-chaining of multiple Aurora converters and other DigiLink devices via
Expansion port.
Lynx proprietary SynchroLock™ technology can be used to reduce jitter when Aurora is a
clock slave or to provide stable, low jitter clock to downstream devices.
Easily installed into Aurora.

3 Before You Begin
We recommend that you read through the manual to acquire an overview of the installation
procedure and use of the LT-HD. This manual will presume a working knowledge of the Aurora
converter. For additional information, please refer to the Aurora owner’s manual.
3.1 Contents
Verify that you received the following in the LT-HD shipping carton:
• LT-HD card in cushioned antistatic bag
• Warranty Registration Card
• User Manual
• 1/2” Standoff Post
3.2 Optional Equipment
DigiLink cables (available from Digidesign) are required for connection to ProTools HD cards.
3.3 Operation Requirements
The LT-HD requires your Aurora converter to have Firmware Version 14 or later. This should
be verified prior to installing and configuring the LT-HD card. To determine what firmware
revision your Aurora has, 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 & 4 or above (i.e. 1&5, 1&6, etc.),
then your unit is compatible with the LT-HD. If pressing Power and Trim does not cause any
LEDs to flash, or causes a single number to flash, then your unit needs to be updated.
Updating the Aurora firmware to version 14 requires a Lynx AES16 PCI audio interface. If your
Aurora has firmware version 13 it can also be updated by a Windows PC or OSX Macintosh via
MIDI, or by a Windows PC via Infrared. The Aurora firmware updater program is 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-HD to Lynx Studio Technology in California. We will
update the Aurora, install the LT-HD 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.
The Aurora/ LT-HD (an LT-HD equipped Aurora) also requires a correctly installed and
configured ProTools|HD system with Digidesign Core, Accel or Process card(s).

6 Installation Procedure
1. Remove the AC power cord and take the top off of the Aurora 16 or Aurora 8. There are
seven large screws plus one small screw near the center of the front faceplate.
2. Before installing the LT-HD card, there is a jumper setting on the Aurora that corrects the
current draw for an Aurora with an LT-HD.
If you are updating a Rev A. Aurora, remove jumper W3 from the JP6 header on the
Aurora mainboard.
If you are updating a Rev B Aurora, slide switch 4 (labeled W4 on PCB) of
SW1 to the OFF position (towards back panel)
Page 5
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-HD
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.
Page 6
5. Install the standoff post (included with the LT-HD) in this same hole.
6. Grounding yourself to the earth ground, remove the LT-HD from its protective static bag.
7. Attach the multi-pin connector on the back edge of the LT-HD to the LSlot connector
(JP1) on the Aurora mainboard. When the LT-HD 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 mainboard.
Use caution to insure that the pins line up as shown. Incorrect installation could
damage the unit.
Page 7
8. Secure LT-HD with three screws; one on the standoff and two from the back panel of
Aurora. Keep screws loose until LT-HD is properly aligned, then tighten snugly, but do
not overtighten.
9. Reinstall the Aurora lid using the eight screws that had been removed. Do not over
tighten the small screw near the center of the front faceplate as it is easily damaged.
10. Plug in and power up the Aurora using the front panel standby switch. You can see the
LT-HD from the slits in the Aurora lid. If the green LED on the LT-HD lights up, the
installation was successful. If the LED does not light, unplug the Aurora and re-mount
the LT-HD, making sure that it is securely attached. Then plug in and power up again. If
the green LED still does not light, contact Lynx Customer Support (949-515-8265 X206).

7 External Connections
The physical connection between the Aurora/LT-HD and Digidesign Core, Process or Accel
cards is very straightforward. Please note: we suggest only using DigiLink cables of 12’ or
shorter for optimal performance.
The LT-HD card has two connectors labeled as PRIMARY and EXPANSION, similar to the
Digidesign HD Interfaces. The port that an interface is connected to will determine how it will be
accessed within the ProTools environment. See Section 10 for information about software setup
considerations.
Connecting a single LT-HD equipped Aurora to a single ProTools|HD Core Card is simply a
matter of connecting a DigiLink cable from the LT-HD PRIMARY port to the ProTools Core
Card DigiLink port. If two Auroras will be connected to the same Core or Accel/Process card,
the first should be connected as described above, and an additional DigiLink cable should be
used to connect from the EXPANSION port on the first interface to the PRIMARY port on the
second. It is not possible to connect more than two Aurora 16s or two Aurora 8s to a single
ProTools|HD Core or Accel/Process card, as there is a 32-channel limit to each card.
There are three possible states for integrating an Aurora into a ProTools|HD system:
• Aurora 16 in 32-channel mode
• Aurora 16 in 16-channel mode
• Aurora 8
In 32-channel mode, all analog and digital I/O channels of the Aurora 16 are available
simultaneously. Since each DigiLink port is capable of 32-channels maximum, in 32-channel
mode it would not be possible to connect a second interface to the LT-HD expansion port. The
Channel Mode for the Aurora can be toggled from the front panel by pressing the TO ANALOG
OUT button for ½ second. The correct mode should be set prior to launching the ProTools
software. In 32-channel mode, the Aurora 16 will appear as two Digidesign 192 I/O interfaces.
Each “instance” will present 8 channels of Analog I/O and 8 channels of Digital I/O - both of
which can be used simultaneously. Combined, this allows 32-channels of input and output to be
available (16 analog/ 16 digital).
In 16-channel mode, each Aurora 16 will appear as a single 192 I/O interface. In this mode, 16
channels of Analog I/O and 8 channels of Digital I/O will be presented to the ProTools software.
Of these 24 possible I/O channels, only 16 can be used at one time. For instance, one could use 8
Page 9
channels of analog + 8 channels of digital or 16 channels of analog I/O at one time. It is not
possible however, to access 16-channels of digital I/O in this mode.
This is the default state for an Aurora 16. If two Aurora 16s will be connected to a single HD
Core/Accel/Process card, both will need to be in 16-channel mode in order for both units to be
available to the ProTools software. This configuration is recommended for those who need more
than 16-channels of AD/DA conversion. Since ProTools will only display 16 analog inputs and
8 analog outputs (this is a limitation of the 192 I/O that the Aurora mimics), the Aurora has been
programmed so that Analog Outputs 9-16 are mirrored by Digital Outputs 1-8 when in 16-
channel mode. If monitoring equipment is connected to Analog Outputs 9/16 and Digital Outputs
1-8, one device should be muted or disconnected to avoid duplicate playback.
Aurora 8’s will always operate in 16-channel mode, where 8 analog and 8 digital I/O channels
are available simultaneously.
If more than 32-channels of I/O is required then additional Digidesign Accel or Process cards
will be required.
If more than 32-channels of I/O is required then additional Digidesign Accel or Process cards
will be required. Possible combinations that can be connected to a single DigiLink port are two
Aurora 16s, one Aurora 16 and one Aurora 8, or two Aurora 8s. In multiple interface
configurations use the Primary and Expansion ports to connect all the units in series. Keep in
mind that each Aurora used in this fashion needs to be equipped with an LT-HD card.
It is also possible to connect LT-HD equipped Auroras in series with Digidesign or other third
party HD-compatible interfaces. In this case, “daisy-chain” the interfaces in the same fashion as
described for multiple Auroras, keeping in mind the 32-channel per HD card limitation. In this
context, LT-HD/Auroras can be connected to the expansion port of the Digidesign/other
interface, or the Digidesign/other interface can be connected to the LT-HD expansion port.
8 Clock Settings
In any audio system with more than one digital device, it is ideal for one master clock to provide
synchronization to all connected devices. There are several options for configuring the Aurora to
send or receive clock within a ProTools|HD environment.
ProTools|HD Interfaces and other digital devices can slave to the sample clock generated by the
Aurora, or the Aurora can be configured to receive clock from another interface or digital device.
It is also possible to have a dedicated clock source that provides clock to both the Aurora and
every other digitally connected device. In fact, if more than two digital I/O devices will be
integrated into your ProTools|HD system, we strongly recommend using some form of clock
distribution to insure proper clock synchronization.
When used with ProTools|HD, there are some differences as to what clock choices are available
for the Aurora, and how they are labeled. Section 9.1 describes which Aurora Sync Source
settings are possible from within ProTools, and section 10 describes how clock source choices in
ProTools are interpreted by the Aurora.
Please see section 2.4 of the Aurora manual for general information about available clock
settings and clocking considerations with the Aurora.
Page 10
8.1 Loop Sync
ProTools|HD features a synchronization system called Loop Sync, which potentially simplifies
establishing clock relationships between connected interfaces and/or other synchronization
devices. When Loop Sync is utilized within Pro Tools, establishing an interface as a clock master
automatically sets other interfaces in the system to slave without changes to clock cabling.
Currently the Aurora only supports Loop Sync completely when used as a clock master (true for
LT-HD firmware revisions 1-5). We do intend to support Loop Sync slave operation in a future
firmware update. Loop Sync is only applicable to cases where more than one interface is
connected to the ProTools|HD system. How it is used (or not used) will vary depending on the
combination of interfaces in the system.
8.1.1 With Multiple Auroras
When multiple Auroras are connected to an HD system, and one will be a clock master, it is
possible to use Loop Sync in a limited form to simplify establishing the clock relationships
between them. Connect the WORD CLOCK OUT from the Aurora selected to be the clock
master into the WORD CLOCK IN on the slave unit. If there are additional Auroras, continue
daisy-chaining the clock outputs to clock inputs for all devices. It is not necessary to connect the
WORD CLOCK OUT from the last device in the chain back to the WORD CLOCK IN of the
master device. When you select “Internal” as the clock source for the master unit in the ProTools
Hardware Setup page, the other units will automatically switch to “EXT” as their clock source.
In the ProTools Hardware Setup page, it is critical that the “Ext. Clock Output” for the master
Aurora be set to the active sample rate, rather than to the ½ or ¼ the sample rate. After
configuring, verify that the slave Auroras are set to “EXT” from their front panels, and that they
display the current sample rate before proceeding.
8.1.2 With One Aurora combined with other Digidesign HD compatible interfaces
When an Aurora will be used along with other Digidesign HD compatible interfaces, Loop Sync
can be used only if the Aurora will be the clock master. In this scenario, the Aurora’s WORD
CLOCK OUT should be connected to the LOOP SYNC IN of the next HD compatible interface.
If there are more interfaces, continue daisy-chaining LOOP SYNC OUT to the LOOP SYNC IN
on the subsequent interfaces. It is not necessary to connect LOOP SYNC OUT from the last
device back to the Aurora.
In the ProTools Hardware Setup page, select “Internal” as the clock source for the Aurora, and
set the “Ext Clock Output” to the current base sample rate (i.e. for 44.1, 88.2 or 176.4 kHz
choose 44.1 kHz, for 48, 96 or 192 kHz choose 48 kHz). In this state, the non-Aurora interfaces
will receive clock from the Aurora and operate at the correct project sample rate.
8.1.3 With a dedicated clock source distributed to multiple Auroras and other
Digidesign HD compatible interfaces
In theses configurations, Loop Sync should not be used. The WORD CLOCK inputs and outputs
should be used on the Digidesign interfaces, rather than the LOOP SYNC I/O, and clock sources
should be set individually to word clock input for each interface via the ProTools Hardware
Setup page.
Page 11
9 ProTools Setup
When an Aurora/LT-HD is connected to a Digidesign Core or Accel/Process card it will
automatically be integrated as an I/O choice from within ProTools. Settings for attached
interfaces are managed from the Hardware and I/O Setup pages within the ProTools Setup Menu.
9.1 Hardware Setup Page
The Hardware setup page within the ProTools software is where settings for connected interfaces
are defined and displayed. This page reveals what I/O choices are available, allows parameters
such as sync source to be set, and allows the user to establish which analog or digital I/O ports on
connected interfaces will be available for ProTools record and play channels.
The Aurora will appear here as a single Digidesign 192 I/O interface when the Aurora is in 16-
channel mode, or as 2 192 I/Os when in 32-channel mode. An Aurora 8 will always appear as a
single 16-channel device. There are important ramifications to this orientation, since the Aurora
offers I/O choices that are not possible with a 192 I/O. The following chart will be a critical tool
to determine how to access the analog and digital I/O ports from within ProTools, since the I/O
types available on the Aurora will not always intuitively match the defined I/O ports in ProTools.
Please note that parameter switches can have different results depending on whether you are
using an Aurora 16 in 16-channel mode, an Aurora 16 in 32-channel mode or an Aurora 8.

After selecting which I/O devices will occupy each of the 16 input and output channels available
on the hardware setup page, these devices can then be assigned to ProTools record and play
channels and labeled from the I/O Setup page

9.2 I/O Setup Page
This page within the ProTools software is where active input and output devices that are defined
in the hardware setup page are assigned to record and play channels for use by tracks and busses
within ProTools.
Click on the INPUT, OUTPUT, and INSERT Tabs and click “default” to create signal paths
based on the I/O defined in the Hardware Setup page. Afterwards, it is generally helpful to re-
label these paths to correspond to Aurora channels (i.e. Aurora Analog In 2, Aurora Digital Out
3, etc.) or to the name of front-end devices which are plugged into the Aurora (i.e. Mic Preamps,
Mixer outputs, etc.).
In cases where the ProTools labels do not define the Aurora I/O type used (i.e. Analog Out 9-16
accessed as AES/EBU Out 1-8 in 16-channel mode), labels can be created here for clarification.
