The Zomo Pro Stand P-400 is designed for the Pioneer CD player CDJ-400. The P-400 is the best way to position the CD player directly above a mixer or turntable. The shelf fits perfectly on the Pioneer CDJ-400 to prevent slipping. It can also be adjusted in height and horizontal angle. The shelf is interchangeable, giving you flexibility if you want to replace your player with a new one. Installing the Zomo P-400 is incredibly simple. With just four screws, it can be placed on any table. If you have the optional base plate, you can also secure the Pro Stand by placing the base plate under the CD player. This way, you will never have to struggle to secure your equipment again. Simply brilliant and totally cool! That's Zomo!.
