There is a safety cut off in the head phone circuit. There was a recall for the first batch of 900 released. But two head phones at once could be a cause.
900 shutting off
my 900 is shutting off in middle of set last night going into sleep mode. it did it 3 times and the sleep function is turned off. but had 2 head phones plugged in would that matter.

When did you purchase your unit? Did you return it during the recall? Are you using headphones other than Pioneer branded headphones?
I believe its one of the recalled ones it was manufacture date of febuary and there is no white dot on side. So i assume it needs to go back
@brandon > No, that would indicate that it was updated; the problem was most certainly that you had two sets of headphones plugged-in. That would cause a change in the impedance great enough to trip the protection circuit. The fix is to either use a headphone amplifier (which has multiple outputs and is designed for just such a task) or don't plug in more than one set of cans!
