Ted,

I am not sure what you mean about a "complete power down". If that involves turning off the power supply, then I cannot comment because my power supply is turned on 24/7. I have never seen that situation. My KX3 turns on the KXPA100, no intervention required.

Based on my experience, I would think that turning on the power supply first, then powering the KXPA100 and lastly the KX3 might prevent the problem. In other words, if the KXPA100 is not powered on first, the KX3 will not recognize it when powered on, and may turn the PA Mode parameter to OFF.

As I said, I never touch the KXPA100, it turns on/off with the power to the KX3.

I have no answer on your PX3 question.

I have had similar experiences.  After a complete power down and later
power up, the KX3 does not know the KXPA100 amp is ready even after both
are powered on, which then requires entering the menu and returning the
right PA setting.  Reminiscent of the pre-fix days when turning on a K3
before applying power to the KAT500 would freeze the K3.

Does anyone know if there is a preferred power-up or power-down sequence
for the KX3 / KPA100 / that would avoid having to do that reset?  I think
this came up on the reflector once before but I don¹t recall . . .

On the other question, about the KX3 and the PX3, there is an option in
the PX3 that would bypass its power switch and have it come on as soon as
power is supplied, and a second option that does the same but leaves the
power switch operable so long as the power isn¹t removed.  Requires moving
a jumper -  p.22 of the Manual.
