Logitek Audio Engine Reference Manual 25
7 Maintenance
The Audio Engine uses multi-layer boards with surface mount technology. As such, the majority of
the engine and its cards are not user-serviceable. However, there are some basic tasks that can be
performed by suitably qualified technical personnel.
Warranty
Logitek Electronic Systems will honor the warranty of the system when conducting field
maintenance, provided:
 Repairs or updates only relate to recommended and documented procedures
 Care is taken and procedures are followed
 Repairs are conducted by suitably trained or experienced service personnel
If you do not feel comfortable performing maintenance or repairs, please do not proceed. If you
would like advice prior to attempting a repair, please contact Logitek Electronic Systems or your
reseller.
Firmware Updates
Each card (with exceptions of the AE-PS Power Supply module and the Lone SHARC DSP) has a
firmware chip that is field upgradeable. Logitek Electronic Systems or your value-added reseller
may from time-to-time supply firmware updates to add new features or fix bugs.
 See Appendix A for firmware revisions.
Each card type has specific firmware that only runs on that card. When fitting updated firmware
ROMs, take care to use the correct chip for that card. Firmware chips are labeled with the card
code, version and date.
A PLCC extractor tool is recommended for removing ROMs. Take care to not bend the pins of the
chip when removing it.
