The Pioneer DJ XDJ-RR is a perfect controller for professional DJ performances. - Model Name: XDJ-RR - Brand: Pioneer DJ - Included Accessories: Power adapter Thank you for viewing. This is a used item, but it has not been used in a permanent setup. It has been used a few times at events. There are no operational problems. The box has some scratches, but the main unit has no scratches or stains. (We will clean and disinfect it again before shipping) The XLR terminal on the R side is damaged, so the sound input will be reduced. I personally connected an amplifier to the L side and used it. I was using it without any other problems.
