The Base Plate attaches to supported VTX subwoofers using their M20 pole mount adapter/plates. Before attaching the Base Plate,
assemble and position the subwoofers at the desired location. For instructions on assembling and attaching the B28 GND or other sub-
woofer-specific accessories, refer to the subwoofer rigging manuals. Follow the instructions below to assemble an A12 array.
STEPS:
• Place the base plates onto the top subwoofer.
• Attach the plates to the outer two M20 attachment points, using the included M20 knobs to secure them onto the subwoofer.

CAUTION: Ground-stacked arrays should always be checked in LAC-3 for mechanical safety . Always secure a
stacked system to the stacking platform or stacking surface to ensure stability and prevent tipping .
CAUTION: Safe limits for ground-stacked arrays always assume that the stacking surface (floor or stage) is flat . To
avoid tipping hazards, do not deploy ground-stacked arrays on non-flat surfaces .
