Sub_Woofer causing Receiver trip-out ?

Archived from groups: rec.audio.tech (More info?)

Going into protect mode when switching sources would usually be a bad
source-select IC in the receiver. If the problem doesn't persist with the
sub disconnected, the sub may indeed be feeding a DC voltage back into the
sub-out jack. Pretty unusual, though.
