One thing that I've noticed is that, for whatever reason, installing the KPA
makes the K2 more sensitive to magnetic fields.  A bit of hum on your signal
might be described as 'raspy'.  The manual now says that you should keep
equipment with transformers or motors in it at least 18" away from your K2.
