!!! Important - This update is only for XTi 1002, XTi 2002 and XTi 4002 amplifiers
with firmware v2.4.0.0 and higher!!!
The XTi2020 version of XTi1002, XTi2002 and XTi4002 amplifiers started shipping in mid-2023. Production firmware was updated to v2.4.0.0 in February 2024 starting with SN 8502018714.
PLEASE NOTE:
You MUST ensure you are using a PC and USB cable that is in good order and working properly. Poor quality USB cables and/or faulty USB ports on your PC can cause the firmware process to fail, which will render your XTi unit inoperable and unrecoverable!
Tools you will need:
- Good quality USB A to USB B cable. Must be USB 2.0 or better!
- Windows PC with Windows 10/11 Operating System
- Audio Architect v2.55.2 or higher
Run CLoader, confirm firmware version:
WARNING: Failure to properly confirm the initial firmware version will result in your amplifier becoming inoperable. If this occurs, it will be necessary to return the amplifier to a service center for re-programming.
Run the CLoader_ver2_225 application, confirm Micro Ver and Flash Ver show as 2.4.0.0 or higher.
Load the firmware into the amplifier:
Click Load File and select the XTI-2400.s (or higher version) file. The firmware update should begin:
When the update is finished, the amp will reboot. The front panel then should revert to the state DSP OFF preset and it will be unlocked:
If it does not reboot or the display does not revert to DSP OFF you should manually reboot the amp by turning it off from the front power button, wait 30 seconds, then turn it back on.
The new firmware version numbers should then be reflected in CLoader:
The firmware update process is now complete. Be sure to use Audio Architect Version 2.55.2 or later when trying to connect your XTi series amplifier for configuring. It will not work with previous versions.
