I have seen that happen with the KPA thought at one time is was associated with something happening on the AUXBUS - like the KAT not being powered up or something. I think maybe there was a firmware upgrade for the KPA and/or KAT that might have fixed it. Are you using the latest firmware?
Glad the KX3 is working ok to drive the KPA. I just fired up the KXPA amp here and am going to play with it and the KPA also.
