TRAKTOR KONTROL S4 Mk2 Instruments TRAKTOR PCDJ DJ Controller I purchased this used in 2022, but I only used it a handful of times. When listing it for sale, I connected it to a PC and confirmed that all buttons and knobs are working. USB and power supply are included. There is no original box, so it will be protected with cardboard etc. when shipped. Software is not included, so please prepare it yourself. I am also selling Traktor Pro 3 separately, so please check that out if you're interested. (I checked the serial numbers for both the hardware and software, and both were already registered.) 【Condition】 Working condition confirmed I have wiped the entire unit with alcohol, but there are some minor scratches, stains, and scuffs. Please check the photos, and be aware that there may be minor scratches that are not visible in the photos before purchasing. I sweat a lot, so there are some marks from that, but there are no problems with the operation. I just tested it and it worked without any problems. To prevent swapping, I have photographed and kept the serial number. 【Included Items】 Genuine USB cable, power cable, various instruction manuals, stickers TRAKTOR DJ controller, 4-channel DJ mixer, built-in 24bit / 96 kHz sound card, and intuitive controller. It perfectly meets professional needs.
