1. Performance at 192khz has been improved
2. You will no longer change sync source in the ProTools hardware setup. Desired Sync Source will be established from the Clock Settings page on the Aurora(n). If using the Aurora(n) on internal clock, then the default settings in ProTools will be fine. If using the Aurora(n) on an external clock source (wordclock or digital in), we suggest setting the clock source for the unit in the ProTools hardware setup page to "wordclock" at the project sample rate.
3. If using an external clock source, and you wish to create or open a project at a different sample rate, we recommend the following steps
   • Close the current session
   • Open the ProTools Hardware Setup
   • Change the sample rate on your external clock source to the rate of the project you intend to open or create
   • Set the sample rate on the hardware setup page for the Aurora hardware to match the external sample rate
   • Close the hardware setup page
   • Open or create a new project at the new sample rate
4. Firmware 15 should remedy AAE errors on launch, as well as noise blasts when ProTools is closed

• Fixed bug in which the word clock output was garbled at 4X rates when syncing to word clock in at BR or 2*BR (EXT/2 or EXT/4) when the analog PLL is active (not with SynchroLock engaged).
• Fixed bug is which the sample rate sent by LT-HD was not getting set properly when the sync source was changed from external to internal. The measured external rate was used but with the sync source correctly changed to internal.
• Fixed bug that caused syncing to EXT with dual-wire enabled to be flagged as a sync error and forced sync to internal with blinking LED.
• Fixed bug that corrupted LSlot I/O and AES I/O if dual-wire in was on at 1X rates. This is an invalid state that was detected in all modules except the port I/O module.
• Fixed LSlot input mux initialization that caused the LSLot Record Sources to startup with the digital inputs selected. This addresses new production units or units that are programmed via JTAG only.
• The operation of dual-wire mode on Aurora?s front panel has changed. In the past, dual-wire could be controlled and monitored by selecting digital as the meter source and then using the TRIM/AES MODE button to toggle between dual-wire settings. In this new version of firmware, selecting digital as the meter source has no affect on the function of the TRIM/AES MODE button. It will always control trim. In order to enable the legacy dual-wire control, hold the TRIM/AES MODE button while AC power is applied. This legacy mode is disabled by either pressing the front panel standby button or removing power from the unit.

  *LT-HD Firmware Version 11 Revision History
  • Made various changes to fix loop sync and clock doubling problems. Loop sync mode is now disabled by default, but can be enabled by setting the S/PDIF format to Tascam in PT HW Setup.
  • Fixed an issue with locking to an external BR clock when the sample rate is 192kHz or 176.4kHz.
  • Added one sample delay for 2X rates to D/A engine to more closely match the HD I/O delay. Difference was 0.8 samples and is now 0.2 samples.
  • Fixed issue in which I/O assignments would change when a project is loaded.
  • Disabled automatic switch to dual-wire for 4X rates and dual-wire control via PT.
  • Added proper sync feedback to PT when syncing to an external clock. If there is a rate mismatch, PT will now pop a clock rate error message that allows the user to correct the rate of the incoming clock to match the current project settings. NOTE: this has been tested successfully for 1X and 2X rates. When launching projects at 4X rates with the clock source set to external, PT will pop a ?number of peripherals has changed? message and force a quit in most cases.
  • Added a switch that enables loop sync mode. This mode should be enabled when Aurora is used in a loop sync chain with Avid products connected via their loop sync I/O. It should be disabled when all devices are syncing to a common word clock generator or are daisy-chained via word clock I/O. Loop sync mode is enabled by setting the S/PDIF format to Tascam in Hardware Setup. Additionally, a clock source or sample change must occur in order for the loop sync mode change to fully engage. All Aurora?s in a system must use the same mode.
  • The external clock output control in Pro Tools Hardware Setup has been disabled. This change was made to facilitate proper operation of the loop sync mode. With loop sync mode is enabled Aurora?s word clock output always runs at the base rate, otherwise it run at the sample rate.
  • Automatic switching of AES I/O to dual-wire mode for 176.4kHz and 192kHz in Pro Tools has been disabled. This change was made to match the HD I/O?s operation at these sample rate.

  • LT-USB now changes the USB PID (product identification) based on the the specific device it is installed in. This means the Aurora 8, Aurora 16 and Hilo now show as independent devices instead of just "LT-USB".
  • LT-USB enabled high-speed UART mode for communicating with the Aurora at faster speeds. Please Note: This requires Build 27 of Aurora firmware to function. You must upgrade the Aurora to Build 27 before upgrading the LT-USB firmware to revision 8.
  • LT-USB now includes serial number as part of the device identification block. This allows multiple LT-USB devices to be connected to a single computer. Please Note: This currently allows OS X to aggregate multiple LT-USB devices together, however the Windows driver does not support aggregating devices for the ASIO driver.

• Added support for LynxTWO/Aurora Interface Kit.
• Added firmware version indication LED's in test mode. Input LED 13 will illuminate solid on the Aurora 16, and input LED 7 will illuminate solid on the Aurora 8. Entering test mode is accomplished by pressing and holding the TRIM switch then quickly pressing the POWER switch. Exiting test mode is accomplished by powering off the Aurora.

• Added initial IrDA support (no IrDA firmware update).

• Fixed spurious noise on multiple channels when trim changed remotely on four channels.
• Added support for LT-ADAT
• Added ability to change power-up mode to either on or stand-by. This mode is toggled by holding the standby switch while power is applied. PLEASE NOTE: After the mode is changed the unit must be put into standby mode to save this setting before power is removed.
• Added the ability to restore factory defaults. This function is selected by holding the sample rate switch while power is applied. PLEASE NOTE: After defaults are restored the unit must be put into standby mode to save this setting before power is removed.

Installation Notes

The firmware update process will take under 1 minute using an AES16; AES16e or LT-USB, and under 10 minutes using IrDA or MIDI. Once the update has been done successfully, your Aurora will need to have the power removed (unplugged) for the new firmware to become active. Please follow the Aurora Firmware Update Instructions for the step-by-step procedure.

If for some reason the firmware update process fails, the current firmware in the Aurora will remain active. You may reboot your computer and re-run the update program to try again.
