JBL VTX A12 SB Suspension Bar
The VTX A12 SB accessory 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 extra down-tilt, otherwise not possible using the VTX A12 AF alone. The VTX A12 SB can also attach to the top cabinet of an array and used as a compact array frame. In this mode, the suspension bar connects to the top cabinet’s rear rigging points and the down-tilt 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: one at the top and one at the bottom of the array, for dual-point applications and added aiming flexibility. The VTX A12 SB can support the weight of up to 18 x VTX A12 enclosures and a 5/8” shackle (included) can be attached directly to the bar.
