The Denon DJ Prime 4 Decksaver is a high-quality polycarbonate cover that has been custom-moulded to match the Prime 4 all-in-one standalone DJ system's profile. It may be used to shield the unit from dust, fluids, or unintentional hits when at home, on the road, or at a club. When used in combination with a protective case, the case is slim enough to provide an additional layer of protection.
