Concert XR 4/6/8 receivers and Maestro X7/X9 processors: firmware update instructions
If your Concert XR4/6/8 or Maestro X7/X9 is on firmware version 1.33 or earlier please contact AudioControl technical support for assistance with updating the firmware. Our technical support team is available Monday – Friday 8am to 5pm PST. 425-775-8461.
Front panel display menu navigation:
Use the “Input + [up arrow]”, “Input – [down arrow]”, “Info [left arrow]”, and “Mode [right arrow]” buttons to navigate to the various menu options. To select a menu setting press the front panel SELECT button. Press the Menu button anytime to exit the menu screens and any setting changes will be saved automatically.
To check the current firmware version of your receiver or processor:
Press and hold the front panel INFO and DIRECT buttons together for approximately 5 seconds. The firmware version will be displayed as a HOST/IAP number, for example 1.47/09. The first number is the firmware version.
Dirac calibration files are now saved as part of the Store Secure Backup function. However, make sure you have access to the Dirac calibration file you created when you were logged into your Dirac account in case you need to export it back to the receiver/processor once the firmware update has completed.
Store Secure Backup of the receiver or processor settings:
Press and hold the MENU button on the front panel for approximately 5 seconds, the Engineering menu will be displayed. Navigate to and select Store Secure Backup > select Enter Pin, the default pin is 0000, press Select. The front panel display should show a “backup successful” message. Press Menu to exit the Engineering menu.
USB DRIVE FORMAT: Format the USB drive to Windows FAT32. Avoid using very large USB drives like 64 or 128GB as these larger drives cannot be formatted to FAT32 (they can only be formatted to exFAT).
Step 1: Power on the processor or receiver.
Step 2: Download the firmware Zip file from the respective Concert XR 4/6/8 receiver or Maestro X7/X9 product pages on the AudioControl website (Downloads section) and save it to the Downloads folder on the computer or you can also find the firmware update files here.
Step 3: Open the Zip folder and copy the AVRx0_System 1vxx (AudioControl).fw file and the image.swu file onto the USB drive. Be sure there are no other files or previous versions of the firmware on the USB drive! Once the copy is complete, properly eject the USB drive from your computer.
Step 4: Plug the USB drive into the rear panel USB port.
Step 5: Press the front panel INFO and DISPLAY buttons together for approximately 5 seconds. The update process will start automatically and will take about 30 minutes. On the front panel display you will see several updates happening: NET, OSD, DSP1/2, DAB, LCD, and MCU. When all of these updates are done the front panel will display a message saying “Update Complete, settings need to be reset, press OK (Select) to continue”. Press Select, the unit will power off. Give the volume knob a turn to restart the unit, the front panel will display “System starting” and “Net starting” for several seconds. Once the front panel returns to an input display the unit is rebooted and you are ready to move on to the next step.
Step 6: After rebooting press and hold the front panel Menu button to enter the Engineering menu to verify that the unit has been updated to the latest firmware. Once in the Engineering menu scroll down until you see the HOST/IAP number and verify it indicates the version you are updating to (for example v1.47/09). Then also check the other firmware segments listed below the HOST number – OSD, DSP, etc. and verify that all of these segments have a version number listed, you don’t want to see any blanks or all zeros, etc.
Step 7: Once the firmware version is confirmed, you can scroll back up to the top of the Engineering menu or, if you exited the Engineering menu then press and hold the Menu button again for approximately 5 seconds. The Engineering menu will be displayed, select Reset to Factory Defaults and follow the prompts to complete the reset. After resetting the unit will power off again. Turn the volume knob to reboot again.
Step 8: You can remove the USB drive or leave it plugged in so you have it for next time there is a firmware update.
To restore saved settings press and hold the front panel Menu button until the Engineering menu is displayed, navigate to and select Restore Secure Backup, you will be prompted with a warning message, select the Direct button to continue and complete the process of restoring your settings.
Also, if you previously loaded a Dirac Live calibration file, press the front panel Menu button > select Input Config > and make sure the Room EQ (Dirac) setting is populated with the Dirac file name you previously loaded. Do this for each input you using.
