The VTX A12 SB is a lightweight suspension bar that can be used as an array frame or to implement pull-back of a VTX A12 array. When used for pull-back, the VTX A12 SB can be attached to the bottom cabinet of an array and connected to a rear suspension point to allow for greater downtilt than is possible using the VTX A12 AF alone. The VTX A12 SB can also attach to the top cabinet of an array and be used as a compact array frame. In this mode, the Suspension Bar connects to the top cabinet’s rear rigging points and the downtilt angle is controlled by the number of cabinets and array geometry. JBL’s Line Array Calculator software application is used to calculate the down-tilt angle. Two VTX A12 SB Suspension Bars can be used for dual-point applications and added aiming flexibility, one at the top of the array and one at the bottom.
