3.9 SWING ARMS
Each LA12 (LA12C) loudspeaker
enclosure is equipped with a flying
hardware located on both sides. Four
swing arms are fitted on the speaker
rigging slots. By sliding out the two
swing arms located on the cabinet
front, one can secure the acoustic enclosure to the upper one or to the flying bar. A safe
fastening is ensured by fitting the supplied quick-release pins in the relevant holes of the
upper speaker system or flying bar. Concerning the two rear swing arms, by sliding them out
the unit can be secured to the upper speaker system or flying bar. The swing arms on the rear
are also used to adjust the orientation,
the vertical angle, between the various
elements. A label stating the specific
holes to be used for achieving a
certain orientation is located next to
each speaker system.
3.10 RIGGING SLOTS
At the front and rear of each loudspeaker system are
rigging slots that have captured inside a swing arm.
At the bottom of the frame, the rear rigging slot has
a series of holes so that the vertical angle between
cabinets can be adjusted by inserting a quick-release
pin in the rigging slot on the frame and the slot of
the swing arm, linking two enclosures together.
