Here you can find the latest firmware version for Anti-Mode 2.0 Dual Core. See below for a list of changes in each revision.

Updating the firmware is easy, but please make sure to follow the instructions carefully. It is especially important to ensure that, once initiated, the update process is not interrupted.

Please do not update unless you absolutely need to!

To update your Dual Core device to the latest version on a Windows PC, please follow the instructions below.

If you have a newly purchased unit, it is recommended to check the version date of the currently installed software before applying the update; you might already have the latest version! To check the currently installed version, navigate to Main Menu > Settings > System Info.

1. Click here to download Updater.exe and save it to any location (e.g. on your desktop)
2. Click here to download the latest firmware package and un-zip it to the same location with the previous file.
3. Connect the provided USB cable between Dual Core and your PC.
4. Please remove any unnecessary USB devices from the PC that are not absolutely required during the update. Connecting Dual Core to an external USB hub during the update is not recommended.
5. Turn on Dual Core and navigate to Main Menu > Settings > PC Link using the remote controller.
6. Ensure that "PC Connected" is shown on the screen before proceeding to the next step.
7. Run the updater program (updater.exe) on your computer by double-clicking the "D" icon. Please note that the updater program will require administrator rights to execute. On an older system, you may need to specify administrator privileges manually: right-click on the program icon and select "Run as administrator".
8. A small dialog window should appear. Click the "Update" button.
9. Open file dialog will appear. Select the firmware package from the step 2 and click Open.
10. The automatic update process should begin. Please wait patiently until the process finishes and Dual Core boots itself. Interrupting this process may cause the device to malfunction so please avoid doing so.

Apr 03 2013

• Fixed: channel delay in digital out mode (S/PDIF) was sometimes set sub-optimally
• Improved compatibility with Linux operating system (USB mode)

Feb 20 2013

• Important notice: If you are using an earlier beta firmware from 2013, please update to the latest release. Performing a factory reset in some of the earlier versions may set the volume level to a very high setting. This behavior should now be fixed.
• Improved USB compatibility with Macintosh computers
• Channel delay dialog improvement; delay values can now be changed permanently without performing full room calibration

Dec 12 2012

• Asynchronous audio transmission in USB mode for improved audio quality
• Improved compatibility in USB mode (Squeezebox Touch via USB etc.)
• Two user-selectable volume control schemes in USB mode: by remote and by computer. "By remote" ensures that volume level stays consistent with other input modes but master volume requests from the computer are ignored. "By computer" setting routes all volume adjustments through the computer. In this mode, a sudden volume change is possible, especially when connecting the unit to a computer for the first time. Please use with caution. Both modes of operation still utilize the high quality analog volume control IC in Dual Core so audio quality is not compromised in either of the modes.
• Added playback controls in USB mode (play/pause and next/previous track)
• Compensation setting of the room correction can now be freely adjusted after calibration (using 0.5dB steps)
• Improved user interface responsiveness (faster switching of sound profiles, faster bypass/Anti-Mode etc)
• New settings menu layout
• New homescreen menu (located in Settings menu) allows re-mapping the remote controller's arrow button actions within the homescreen. Separate functions can be assigned to left/right buttons and up/down buttons. The choices are: bass, treble, (full spectrum) tilt, loudness, next/previous track in USB mode, next/previous input switching and off. The OK button can be assigned to either Play/Pause function (in USB mode) or main menu access. (Playback control commands require compatible software on the computer side.)
• Highpass and lowpass filters can now be assigned on per-channel basis (allows "1.1" operation).
• Added numeric feedback for QuickTone adjustments

Oct 4 2012

• Audio in the USB mode was sometimes muted when toggling the inputs; should be fixed now.
• Added new feature. QuickTone gives four options for quick and easy tone control without leaving the home screen (Tilt/Bass/Treble/Loudness). Navigate into Main Menu > Settings > Audio Settings > QuickTone to enable it. After QuickTone is enabled, use the up/down arrow buttons at the home screen to make a +/-1dB adjustment. (The last option "Input" is not a tone control but allows quick input switching using the same buttons.)
• Added new feature: full screen dim. At the home screen, press and hold the blue (display) button for a short time to turn off the display completely. Press the same button shortly to turn it on again.

Aug 16 2012

• This fix is intended for those who use the dual mono mode. It should correct an issue which could inadvertently disable audio routing to the other channel in certain situations. If you are not using the dual mono mode, you don't need to apply this fix.

Jun 14 2012

• Added new feature: low-midrange measurement which allows to measure and view the response between 16-500Hz (also supports cursor tracking). The old "Bass" measurement was re-named to "200Hz"
• Full-Range measurement is now smoothed (1/6 oct.) for better visual clarity
• Improved advanced calibration above 200Hz
• Corrected problems with such digital s/pdif sources that send non-audio data when paused
• Measurement menu now defaults to the selected output
• Left/right speaker selection in the measurement tool now works for digital output
• Small minor improvements

Jun 07 2012

• Added new feature: frequency tracker to observe measurement data using cursor
• Added a dashed line on the before/after graph to indicate the upper limit of the correction range
• Improved s/pdif synchronization
• Exported measurement files are now more intuitively named (according to profile and measurement type)
• Left/right input switching revoked (based on user feedback)

Jun 01 2012

• Fix: dual mono mode was previously not active after calibration/profile change/factory reset

May 30 2012

• Volume adjustment in USB mode no longer interrupts the audio
• Adjusting volume from computer in USB mode no longer causes glitches in audio
• Input overdrive warning added
• New translations: Swedish, Dutch, German
• Multi-point calibration was not always enabled after the primary calibration; should be better now
• Full factory reset now clears all settings (volume, number of profiles etc)
• Added manual channel balance adjustment
• Added input volume trim: adjust the relative volume of S/PDIF and analog inputs
• Default input sensitivity changed to "low" for better compatibility
• Added user-adjustable input sensitivity: better support for "hot" audio sources (DACs etc)
• Fixed rare audio glitch with certain digital audio sources
• Left/right arrow keys can now be used to switch active input
• More visible indication of bypass mode
• Miscellaneous small fixes

Apr 19 2012 R3

• Analog input sensitivity increased (from 1.6V to 3.25V with RCA; from 1.3V to 2.6V with XLR). Fixes analog incompatibility with certain "hot" audio sources (DACs etc) that output at excessively high voltages.
• Improved digital compatibility with certain devices (in rare occasions there was a possibility of audible glitches)
• Fixed GUI slowdown when entering the menu from USB mode

Apr 19 2012

• The initial release.
