The JBL VT4888-AF is a robust and precision-engineered array frame designed specifically for flying and ground-stacking the JBL VTX A8 and VTX A12 line array loudspeaker modules. As a critical component of the larger VTX series touring sound system, this frame provides the secure mechanical structure required to assemble multiple loudspeaker cabinets into a unified, vertically splayed array. Its primary function is to ensure accurate inter-cabinet angles, proper weight distribution, and safe suspension, which are all essential for achieving the intended acoustic performance and coverage of the line array system.

Constructed from high-strength steel, the frame incorporates JBL's proprietary, user-adjustable cam-lock mechanisms. These cams allow audio technicians to quickly and precisely set a range of splay angles between adjacent cabinets, enabling fine-tuning of the array's vertical dispersion to match the specific geometry of the venue. The frame is engineered with integrated, multiple rated rigging points that safely transfer the load of the entire array to the primary suspension hardware, adhering to stringent safety standards for overhead flying.

The VT4888-AF is built for the rigors of touring, featuring a durable black powder-coat finish and a design that facilitates fast assembly and strike. It is an indispensable tool for system technicians, as it directly links the individual acoustic performance of each VTX cabinet to the collective behavior of the array. By providing a reliable and adjustable structural interface, this array frame ensures that the powerful, coherent sound output of the VTX system can be deployed consistently and safely in large-scale live sound applications.
