The Raxxess Etude is perfect as a studio keyboard workstation or as a learning center. The frame is constructed of 1-inch by 2-inch tubular steel side supports of 16-gauge material. The fabricated bottom cross member is 1 1/2 inches by 6 inches. Both the keyboard shelf and the optional printer/CPU shelf (not pictured) that mounts to the lower portion of the frame are adjustable in one0inch increments for up to five inches. They each measure a generous 55" wide and 16" deep. The 55" width will support an 88-note keyboard while the contoured upper shelf can easily accommodate audio and video monitors. A computer keyboard shelf can be mounted to either of the two standard shelves using the hardware provided into pre-drilled holes.
