I had it set up in a rack, but I rarely used it. The unit itself is almost flawless, with only minor scratches on the top and bottom surfaces from when it was in the rack. It was very useful, but I'm selling it because I'm reorganizing my equipment. It's a 16-channel XLR balanced patch bay with power pass-through. - Model: P16 - Number of channels: 16 channels - Connection type: XLR balanced connection - Output function: Power pass-through - Brand: ART Thank you for looking.
