ATTACHING LOUDSPEAKERS TO TRANSITION
FRAME
This procedure can be completed with two stagehands, but
is most efcient with three.
1. Position loudspeakers at their approximate desired
horizontal splay angle.
2. Prop up all rings and stud rigging rings to their upright
position and parallel with the corresponding frame
holes.
3. Place the rear arm across the top of the loudspeakers
— on the inside of the rigging points — anges up.
Note the appropriate slots in the rear arm for the
loudspeakers and the desired splay angle:
— Rectangles denote MSL-4s
— Circles denote CQs.
The number inside of the shapes denotes the horizontal
splay angle.
4. Position the rear arm over the rigging rings so that the
rings slide up through the slots. Some repositioning
may be necessary to align the rigging rings and slots.
5. Slide the oval handle hitch pins from the rear, across
the top of the rear arm and through the rigging rings
(and vertical rib or the arm itself) until the hitch pin collar
stops against the side of the rear arm.
6. Insert a lynch pin into the hole in the oval handle hitch
pin. This will lock the pin into place so that it cannot be
removed.
7. Follow the same steps (steps 1 through 6 above) to
attach the front arm.
