User Manual Please Note: The LT-HD requires your Aurora converter to have Firmware Version 14 or later. Any Aurora shipped from Lynx Studio Technology prior to August 22, 2006 will have previous firmware installed in it. For information about updating the Aurora’s firmware to a compatible revision, see section 3.3: Operation Requirements. Lynx Studio Technology, Inc. www.lynxstudio.com support@lynxstudio.

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

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 relabel these paths to correspond to Aurora channels (i.e.
10 Aurora Parameter Controls Since the Aurora with an LT-HD installed is intended to be accessed and identified as a Digidesign 192 I/O, all routing and system settings that are applicable for ProTools sessions should be initiated from within ProTools. There is no mechanism for parameter changes initiated from the interface device to be communicated and correctly displayed within the ProTools software.
AES B LSLOT This is not a possible setting when using an Aurora 16 with ProTools. If the Aurora is to slave to an AES signal, the clock source should be connected to AES I/O 1-8 (Port A). Aurora 8 Clock signal from the AES inputs 5-8. Not applicable when used with the LT-HD. If no clock signal is available for the SYNC SOURCE selected, the LED for the selected source will flash, and the Aurora will operate from its internal clock.
10.2 Aurora Remote Control Software The Aurora Remote Control software can operate on an OSX or Windows PC computer via a Lynx AES16 audio interface or MIDI. It can also operate on a Windows PC computer via IR. As is the case with the front panel controls, parameter selection is limited when the Aurora is operating in “ProTools LockOut” mode. In this mode some parameters will be “locked out” and not alterable, and others will function normally. This holds true for all of the controls detailed in Section 10.
