FW Rev C - Increased the fan turn on voltage because some fans wouldnt come on at the initial startup voltage. 4. FW Rev D

9、- Adjusted fan thresholds to accommodate hardware changes and modified limiters based on amplifier updates. Notes: FW Rev D IS NOT compatible with older amplifiers which have FW Rev A-C and vise versa amplifier with FW Rev D cannot be downgrade to earlier FW revisions (A-C). d. K-Series power amplif
