DENON DN-X1100 In my personal opinion, this unit is in quite good condition for its age. Based on a simple amateur inspection, I have confirmed that sound is output from CH1, 2, 3, and 4 using CDJs and record players. I have also confirmed the operation of each CH EQ, CUE, and GAIN. I have confirmed that sound is output from each CH fader from phono1234, and that each effector is working. As far as I have inspected, I have not found any defects. However, due to its many functions, it is difficult to grasp and master them in a short time. Due to the short inspection time, there may be defects that I have overlooked. I believe I have inspected the key points. I do not understand all the functions, and I have never used a new or near-new unit, so I honestly don't know if I am using the functions correctly. Please understand that I cannot perform a complete inspection, and that this is an old product before purchasing. * To ensure everything is in order, I will re-inspect and clean the unit before shipping. * Since this is a short, simple inspection, there may be overlooked defects. Please keep this in mind when purchasing, as this is an old product. I will accept returns for legitimate reasons. * I will not sell to those who are overly concerned about details or who are looking for a perfect product. Shipping is included. I have noticed that some people are copying my text. I will report them as soon as I find them.
