Question:
How can my Crown XTi6002 be unlocked?
The front panel is locked and pressing the Prev/Up and Next/Down buttons does not unlock it.
The access control password in Audio Architect has been lost so it cannot be added to a new venue.
Answer:
The Crown XTi amplifier requires a complete factory reset. Note that all settings, Presets and Hi Qnet Name will be lost. Hi Qnet Node Address will not be reset.
These amplifiers require a firmware transfer to be factory reset. When Access Control is enabled and the password is unknown, this can only be done using the CLoader program.
The zip file includes the CLoader v2.25 and the v2.0.4.2 firmware files for XTi6002.
WARNING:
Failure to follow the instructions below will result in your amplifier becoming inoperable. If this occurs, it will be necessary to return the amplifier to a service center for repair.
DO NOT send XTi v2.0.4.2 firmware to any amplifier model other than XTi6002.
