My first suspicion is that the ALC is continually building as you
speak. You should be able to confirm that by switching the LED bargraph
display to indicate ALC - if the ALC meter does decrease between voice
peaks, but slowly builds up, you should see it on the bargraph.

That caveat is not required. The K2 will detect the KPA100 when it is

A ground fault is either an open ground wire in the AC wiring system, or
it is more commonly a short of the hot wire to ground (could be just
leakage, like leakage from a capacitor from the hot wire to the chassis).
