I have just sold my 568/562.V2 in favor of an 861. Mine is a V4 upgrade. While switching between sources this evening, the 861 seemed to lock up (no audio from any source). I cycled the on/off switch on the back and that seemed to clear the system and reset so to speak.

I had grown used to cycling the on/off switch of the 568 for the purposes of connecting to my computer, but I do not ever remember using the on/off switch to sort of reset the system. Is this something that is particular to the 861? Might I have done something that caused it to lock?
