13 - GROUND STACKING THE VTX A12
The VTX A12 VT GND outrigger system allows A12 enclosures to be ground stacked without removing them from the VTX A12 VT Verti-
cal Transporter cart. The two outriggers extend in front of and behind the stack, and connect to the VT using the included quick release
pins. Screw jacks are used to lift the stack off the ground, and the innovative, spring-based, angle set hinges are used to adjust overall
aiming. The hinge mechanism uses gas springs, which allow adjustment of the overall stack angle without manually lifting the speakers
or moving heavy parts. Depending on the array geometry, the VTX A12 VT GND can support the weight of up to six A12 cabinets and
allows for angles ranging from -15 degrees to +5 degrees. LAC-3 software calculates ground stack parameters and mechanical safety.
