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

[e-mail]

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).

or call 949-515-8265 ext 206.

4 Nomenclature used in this manual

The following typographic conventions are used in this manual:

 ALL UPPER CASE TEXT refers to a specific parameter selection control (i.e. SYNC

SOURCE) or a cable connection.

 Text in quotation marks indicates a parameter selection value or menu option (i.e. “EXT”).
 Phrases, such as: Click Setups Menu > Hardware Setup, use the greater than symbol (“>”) to

indicate multiple menu options or mouse selections within a software control context.

5 Warranty Registration

We are committed to providing you with the best service possible. To help us serve you better,
please be sure to register your LT-HD using one of the following methods:

• Fill out and mail the Warranty Registration Card included with your LT-HD.

• Register on the web at:

http://www.lynxstudio.com/support.html

Once you are registered you will automatically receive notifications of new products and
upgrades.

5.1 Locating the Serial Number of Your LT-HD

To register your LT-HD, you must supply its serial number. The serial number is located on a
label attached to the back (solder-side) of the LT-HD board, and also on the shipping carton.

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 4

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 5

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.
