Aurora(n) Firmware Revision History

Version 1.32 - October 12, 2023

• Dolby ATMOS filters are now stored in the startup scene. After an ATMOS Scene is made active, you should be able to power cycle the Aurora(n) and have the ATMOS Scene stay active. The scene is saved to EEPROM immediately upon opening a scene from the SD card or pressing "Apply" from NControl.
• The ATMOS Enable checkbox should now accurately show the state of the Aurora(n).
• When recalling an ATMOS Scene from the SD Card, if the scene did not have an LFE channel, it would not load properly. This has been corrected.
• When recalling an ATMOS Scene from the SD Card, the scene is marked as an active NControl scene so the routing page will warn about losing the scene.

Version 1.31 - March 17, 2023

• Added ATMOS support.
• Changed Trim values to show full scale value: +20 dBu and +6 dBV.
• Moved Restore Defaults from About page to Function Menu.
• Moved SD card Format from SD Card page to SD Menu.
• Added SD Menu to Function Menu. Moved "SD Card", "Sessions", "ATMOS Scenes", "Scenes", "Playlists", "Format" and "Firmware Update" to SD Menu.

Version 1.30 - March 17, 2023

• Fixed issue with SD Record Setup page where the last selected group could have been hidden.
• Fixed issue where selecting only LSlot inputs on SD Record Setup page would not turn on Record button for the LT-DANTE board upon power up.

Version 1.29 - January 18, 2023

• Fixed SD Record Setup page when no SD card is inserted.

Version 1.28 - November 11, 2022

• Fixed issue introduced with Version 1.27 that kept the firmware upgrade process from completing successfully when upgrading with LynxFirmware application. If you have Firmware Version 1.27 currently on your Aurora(n), you must upgrade the firmware using the microSD card. Instructions for this are linked on our website.

Version 1.27 - October 11, 2022

• Fixed issue where the installation of an LM-A24 or LM-A4 into the upper slot in Bay 1 would disable the inputs of an LM-AIO8E board at sample rates above 48kHz.
• Fixed issue where the installation of an LM-A24 would swap the controls of the two output trims for any LM-AIO8E board.
• Fixed issue where selecting only LM-A24 inputs on SD Record Setup page would not turn on Record button.
• Fixed issue where selecting only LSlot inputs on SD Record Setup page would not turn on Record button.

Version 1.26 - March 1, 2022

• Added SD Record Enable to remote registers so NControl can update the SD Record Enable. Only available with NControl 1.0.7.4 and higher with MIDI Control Surface enabled.
• Changed timing on setting LSlot device ID to improve firmware revision detection on LT-DANTE.
• Fixed issue where NControl could not get volume or pan for source channel exactly equal to 32 (setting worked correctly). Requires NControl 1.0.7.4 or higher.

Version 1.25 - August 13, 2021

• Added Play pan and volume controls for the first 12 outputs, Phones and the selected Monitor Out. Only available with NControl 1.0.6 and higher.

Version 1.24 - July 6, 2021

• Fixed issue where NControl may see meter activity stop after a period of time.
• Fixed issue where NControl could not control volume or pan for sources greater than 32. If the Aurora(n) has more than 32 inputs, NControl 1.0.5 or higher is also required for this to work properly.
• Fixed issue where 48V and PAD relays may not engage for Preamp Channel 1 on certain configurations of Aurora(n).
• Fixed issue where some control changes may not be applied when recalling a scene from NControl.
• Fixed issue where LSlot record source would not save or recall properly from Scenes page.
• Changed pan control to a modeled cross fader instead of a linear cross fader to more closely match to a physical hardware pan control.
• Added Pan law to Settings page with values of 0.0dB, 3.0dB, 4.5dB or 6.0dB. This allows the user to set the amount of gain reduction applied when a mono source is panned to the center.
• Added Swap A/B to Settings page: Rotary encoder click. When selected, pressing the rotary encoder when on any meter page will cause the "Group A" and "Group B" mutes to be toggled. This allows for two set of outputs to be swapped for comparison, such as full range monitors vs. control room monitors or a surround mix to a stereo mix. Selecting "Swap A/B" will also set "Group A/B" as the "RE volume" and set "RE wheel" to Volume.
• Added Mute to Settings page: Rotary encoder click. When selected, pressing the rotary encoder when on any meter page will cause the selected "RE volume" output pair to be muted.
• Added "Mute" indication to volume popup.

August 20, 2020 - Version 1.23

• Fixed issue where trim may not be recalled properly upon power up with LT-USB installed.
• Added support for "Group A" and "Group B" master volumes.
• Group A or Group B can be selected as the Rotary Encoder volume so entire sets of channel volumes can be controlled with the rotary encoder.
• Only NControl can assign outputs to Group A or Group B (NControl 1.0.2 and up).
• By default only Group A is enabled, Group A volume is unity and all outputs are assigned to Group A. This allows Group A to be selected as the monitor out volume controller in the Settings page and control all outputs with the rotary encoder.
• Added the ability to format the microSD card with exFAT format through the SD Card page.
• About page channel display changed to only show types of channels currently installed.

March 26, 2020 - Version 1.22

• Added "Playlists" page. Please see the Aurora(n) User Manual for full details on Playlists.
• Scenes are now named *.ncs to match NControl, so scenes can be directly shared between NControl and the Aurora(n).
• Scenes saved on the Aurora(n) now have the source volumes encoded to match NControl.
• After recalling a scene that scene name is now shown with a highlighted background and the user interface stays on the Scenes page (instead of switching to the Meters page).
• Fixed startup issue seen with a very small number of Aurora(n)'s with Firmware Version 1.21.

Feburary 15, 2020 - Version 1.21

• Added support for DB-ADAT connected to LM-DIG. Please note that LM-DIG must have Firmware 2.0 installed to support DB-ADAT. Upgrade order should be:
  1. Install Firmware 1.21 on Aurora(n) then power off Aurora(n).
  2. Install Firmware 2.0 on LM-DIG then power off Aurora(n).
  3. Install DB-ADAT.
• Added "Optical Settings" page which allows selection of Optical Out Mode of either ADAT, SPDIF or following the format of Optical In 1. Default is "Follow Optical In 1".
• When a DB-ADAT is installed, on the Horizontal Meter Page > Meter Select will only show ADAT In and ADAT Out when user presses and holds the Function button for 1/2 second. Function button will have a blue back-light when over AES In, AES Out, ADAT In or ADAT Out as a reminder of the "hidden" function.
• Added "Scenes" page. This new page allows saving and restoring scenes (which include all routing options) to the /Scenes folder on the microSD card. The scene file format is the same as the NControl scene format so scene files can be easily shared between the two. This makes recalling a specific routing setup in the field without a computer connected easy as the routing can be saved from NControl and recalled directly on the Aurora(n) from the microSD card.
• Changed how "To LSlot Out" (where LSlot is replaced with the computer interface name) is selected on the Routing page. Now each source type can be enabled or disabled independently just like the "To Line Out" and "To Digital Out" routing options. If there are too many source channels to route to the LSlot outputs (when the USB is in 8-channel mode, for instance), source buttons are turned off to show which channels are actually being routed. Please note that Preamp In source will never be automatically turned off. This means that the Aurora(n) PRE1608-USB model running in 8-channel USB mode will need to have the Preamp In source turned off manually before Line In source can be selected. Custom LSlot channel routing can be done in NControl by using the Menu > LSlot record source (again, where LSlot is replaced with the computer interface name.)

November 5, 2019 - Version 1.20

• Improved LT-HD2 sample rate changes to prevent ProTools error messages with HD Native card (requires LT-HD2 firmware 6).
• Fixed issue where NControl LSlot record routing was being overwritten on startup.
• Fixed issue where SynchroLock would unlock if clocking externally and microSD card record was started.
• Please note: If the Aurora(n) currently has 1.14, 1.16 or 1.18 you must update the firmware using the microSD card method described above.

August 5, 2019 - Version 1.19

• Fixed issue that prevented NUpdate from completing a firmware update over the bus (Thunderbolt, Dante or USB). If the Aurora(n) currently has 1.14, 1.16 or 1.18 you must update the firmware using the microSD card method described above. If the Aurora(n) has 1.10A or below, NUpdate will function normally.

April 4, 2019 - Version 1.18 BETA

• Fixed issue that ignored FAT32 4GB file size limitation for the SDCard support (32GB or smaller microSD cards). Now when a FAT32 formatted microSD card is used, the time remaining will count down to the 4GB file size limitation instead of the space remaining on the SDCard. Recording will automatically stop when the file reaches 4GB in size. Formatting with exFAT removes the 4GB file size limitation.
• Added Settings page to allow user to select 5 customizable settings:
• Phones Source: Allows the user to set the Basic or Advanced phone source page is shown when the "Phones Source" button is pressed. Please note that when using NControl the Aurora(n) will only show changes in NControl when using the Phones Source Advanced page.
• LSlot Meter: Allows the user to select if the LSlot meter page is shown as Separate or Combined (if possible). Previously if the LSlot meters could fit on a single "All I/O" page, it would combined them. Now the user as the option of forcing the LSlot meters to a separate page. If there are too many meters for a combined page, the Combined button will be disabled.
• RE click: This setting allows the user to select what pressing the rotary encoder button will do when on the meter pages. Valid selections are:
• Function Menu (abbreviated "Function") will show the Function Menu.
• Preamp (if a LM-PRE4 board is installed, will show the Preamp page.
• DIM, will reduce the volume of the Monitor Out by 20dB.
• Nothing, will do nothing when the rotary encoder is clicked. This prevents and inadvertent rotary encoder bump from changing settings on the Aurora(n).
• RE wheel: This setting allows the user to select what rotating the rotary encoder will do when on the meter pages. Valid selections are: SD Shuttle (previously the only action available) and Monitor Out Volume (abbreviated "Volume"). When Volume is selected, the Monitor Out volume is set with the Monitor Out button.
• Monitor Out: Allows the user to select which output pair are designated as the "Monitor Out" for both the "RE click: DIM" function and the "RE wheel: Volume" function.
• When date and time are set from NControl, a date and time popup appears over the meters page for 3 seconds to let the user know the setting was accepted by the Aurora(n).
• Preamp Settings page: Removed "Rotary encoder click" setting as this is now changed on the "Settings" page.
• Allowed remote control of the "Monitor Out" channel selection from NControl. Hold the "Control" key on the keyboard while clicking on the output select button. Visual indication of the Monitor Out select is show as a highlighted box around the name of the output selected.
• Fixed a bug on the Phone Source Advanced page where the Function button was Cyan instead of Blue (pressing Blue Function button moves the Blue group focus; pressing the White Select button moves the White control focus).
• Added front panel control lock function to disable all front panel buttons. Press and hold the "Meter/Exit" button for 1/2 second to engage front panel control lock. All button LEDs will go out except "Meter/Exit" will turn Red. Press and hold the "Meter/Exit" button for 1/2 to turn off front panel control lock.

January 14, 2019 - Version 1.16

• Added support for LT-HD2 LSlot card.

November 28, 2018 - Version 1.14 BETA

March 12, 2018 - Firmware 1.9

• Lynx recommends doing a Restore Defaults after a firmware update. Function Menu > About > Select > OK.
• Fixed issue where LT-HD would not identify the correct number of channels available on some units with 24 or 32 channels.

Feburary 28, 2018 - Firmware 1.8

• Lynx recommends doing a Restore Defaults after a firmware update. Function Menu > About > Select > OK.
• Added support for LM-PRE4 module.
• Changed UI theme with new font and new color scheme.
• All I/O meter page now shows as many channels as possible on a single page. If a second page is needed for the LSlot channels, user should press Meters/Exit button to see metering for the LSlot channels.
• Changed SD Record Setup page to allow for individual channel selection.

November 9, 2017 - Firmware 1.7

• Lynx recommends doing a Restore Defaults after a firmware update. Function Menu > About > Select > OK.
• For Aurora(n)-16 USB only: To Digital Out source for USB Play are channels 1-16 instead of just after the analog channels.
• Added the ability to update LT-HD firmware from the SD card.
• Added support for LM-DIG board in UI. If LM-DIG board is installed in SLOT 4 (under LSlot connector) this will add 16-channels of AES/EBU. Please note the LSlot boards have a maximum of 32-channels, so an Aurora(n) with 24-channels of analog i/o and an LM-DIG will exceed the maximum channels that can be routed to the LSlot board. The Routing Menu allows the user to select having either the Analog channels first, or the Digital channels first to accommodate this.
• Phones Source: Mixing and individual input volume control are now possible for the phones source. Please see Section 6.3 of the Aurora(n) User Manual for more information.
• Phones Source: If SD Card is not installed, SD Play channels are no longer shown.
• Phones Source: If LSlot (Thunderbolt/USB/Dante/HD) is not present or not connected, LSlot Play channels are no longer shown.
• Test Tone: Added the ability to send test tone to the LSlot (Thunderbolt/USB/Dante/HD) outputs, to aid in testing computer routing and connection issues.

July 11, 2017 - Firmware 1.5

• Fixed screen DMA copy issue while recording at high sample rates/channel count.
• Ignore hidden folders (Sessions) and files (Takes).
• Fixed issue where renamed Session would not update the take names because the session folder had changed out from underneath the take.
• Changed horizontal meter scale to go from -80 to -60dB to match All I/O page meters.
• Disallowed LSlot clock update while recording and playing.
• Horizontal meter page: Fixed bottom meter right channel overloads
