Attaching Pullback Bar to PL-LA
The Pullback Bar will be located at the back of the loudspeaker. This method is utilized when the Pullback Bar is used to achieve array
angles that would not be possible by gravity alone.
Pullback Bar Deployment
The Pullback Bar can be used in two use cases:
1. When gravity alone does not allow
reaching the desired down tilt angle, the
Pullback Bar can be used on the rear of the
lowest loudspeaker of the array to provide
another pick-point for further support to
angle the system.
2. A small number of boxes can use the
Pullback Bar PL-LA-PB in lieu of the
Array Frame. See "Suspending PL-LA
Loudspeakers using Two Pull-Back Bars" on
page 27.
WARNING!:
The load angle
with the vertical at the attachment
point should be between 0° and
45° as shown in Figure 23.
WARNING!:
Only use pick-
point number 1 to 6 on the Array
Frame. See page 11.
