Refer to the free VLA-C Calculator software for the array size cabinet suspension limits for your
particular configuration.
7 - BRACKET PLATES
(ie, Angle Brackets)
Each loudspeaker model ships with a corresponding pair of bracket plates which can be seen here:
VLA-C125S
VLA-C265
VLA-C2100
Orientation: Note that the FRONT arrow must always point toward the front of the loudspeaker
cabinets. This places one dot-outlined section on the top, which connects via two bolt points to
the top loudspeaker cabinet, and it places the other dot-outlined section on the bottom, which
connects via two bolt points to the lower loudspeaker cabinet.
Attach the Appropriate Plate -- See charts below for which plate and which holes to use, based on
the cabinet models and the desired inter-cabinet splay angle.
Bolt Installation – Select the bolt holes in the bracket plate that correspond to the two cabinet models
that are being connected by that plate and the desired inter-box angle setting. Use the supplied
stainless steel M10 x 35 mm bolts and lock washers to secure the angle plates to the cabinet. Remove
the neoprene washer from the locations used to attach rigging components. Insert two of the M10
bolts (with lock washers) through the holes in the top section of the bracket and thread them into the
two bottom threaded insert points in the top cabinet. Insert two of the M10 bolts (with lock washers)
through the corresponding holes in the bottom section of the bracket plate and thread them into the
two top threaded insert points in the bottom cabinet. (See diagrams)
INSTRUCTIONS

Loctite brand Blue 242 on the threads of all fasteners. Torque bolts to 29.5 ft•lbf (±3
ft•lbf); 40 N•m (±4 N•m)
NOTE
: The composite enclosure will make noises as bolts are tightened – this is normal.

Philips screws. Torque screws to 2.0 ft·lbf (±0.2 ft·lbf); 2.6 N·m (±0.3 N·m).
