Thank you very much for viewing. As I will be entering a busy season starting in April and my environment is about to change significantly, I am regretfully organizing my equipment. The following is a description of the product. This is a DJ controller compatible with Serato DJ Pro. I previously purchased it as a junk product, but its operation has improved after maintenance. The cause was due to firmware and the specifications of the PC/Mac, but the operation has become stable through various firmware updates (including CPU). Windows 11 Home Ryzen 7 3700U ROM 12GB SSD 512GB Serato DJ Pro 4.0.2 There should be no problems with either PC or Mac if they have similar specifications. There are no operational issues with the switches, faders, JOG, PAD, sequencer, etc. It is in relatively good condition, but some stains can be seen on the surface. As accessories, I will include the original power adapter and box. Please understand that this is a used item before considering a purchase.
