Question about Pioneer Audio & Video Receivers
It sounds to me like an audio enhancement filter is malfunctioning. The pure direct on / off is a sound filter to alter the sound performance of the receiver. There is a rare possibility that there is something wrong with one of your speakers- causing certain circuits in the receiver to malfunction. A way to check for this is to connect only one speaker and an audio source. test each channel first(without pure direct) by connecting the speaker to a channel and then disconnecting it, and connecting it to a different channel repetedly, until you have gone through all of the channels. If you really wanted to pinpoint such an anomaly, then you would need to do it with every speaker through all of the channels to make cetain that this is not the case. But then again this is not very likely. I would personally just use the mode that seems to work, because something is obviously malfunctioning, or possibly burned out. And repairing it is most likely costly! I hope that you can get something out of my answer! sorry! Good Luck!
