The RK-1 is a rack mount kit for the DC-1, SP-1, and PA-1. The RK-1 allows you to mount either a single unit, or two units side by side, in a standard 19” rack. The RK-1 is made from heavy gauge steel, and ships with two interchangeable 8mm thick milled aluminum faceplates. The single plate holds one DC-1, SP-1, or PA-1 in the center position; the dual-plate holds a pair of DC-1s, SP-1s, PA-1s, or one of each, securely side by side.
