    works great until u turn up the volume more than half way than i get a
    protect error. Have checked for bad caps all seem to be fine unless i am
    missing one. Has anyone else had this problem and if so how did u resolve.
  2. Maybe a problem with your speaker load - too low an impedance or too many
    speakers hooked up. Excess current flow triggers the protect circuit to
    (hopefully) prevent the amp from frying. Try playing a bit lower, and / or
    lowering your bass / treble / loudness - bass boost settings.
    Possibly a stray speaker wire shorting out. Check the wires.
    Could be a defective (damaged) speaker.

    I don't think the problem is actually in the receiver at this point.

    Most receivers are already clipping by the time the volume control is
    at the one o'clock position. The extra range is there in case you have
    a really low source. If you are hearing distortion at the point where
    it is going into protection, then you are asking too much from the
    receiver. Also, most surround receivers have only one set of speaker
    outputs for a reason, which is that they can't really drive 2 pairs of
    speakers at a time.
