Dick, If you use the AUX cable between the K3S and the KPA500, check the ALC THR setting on the KPA500 to be sure its ALC threshold level is not set too low.
Have you tried running the K3S directly into a dummy load to see if the ALC behavior is the same as what you've observed (or run the KPA500 in STBY mode to bypass its PA)? Just wondering if the issue arises in the KPA500 ALC feedback to the K3S rather than directly in the K3S itself?
