Connect Pull Back Bracket to Full-Range Module

Attach the ShowMatch Pull Back Bracket (SMPULL) to the bottom full-range array module to provide a

third structural attachment point when creating an array with a more extreme downard tilt.

The pull back bracket provides three rigging points along the rear to connect a pullback cable or the

Transition Bracket Accessory (SMSTK). For more information about the Transition Bar Accessory, see pro.

Bose.com.

When connecting a pullback cable, it is recommended to use either the center rigging point, both side

rigging points, or all three rigging points. The primary suspension points of the array frame should be as

close as possible to the center of gravity of the array to minimize the tension load in the pullback cable.

Use Bose Modeler software or the Bose Array Tool to determine if the pull back bracket is required and to

confirm that the pullback angle and working load is within acceptable safe limits. For more information on

Modeler and the Bose Array Tool, see pro.Bose.com.

Note: The Pull Back Bracket is not intended to provide primary structural support for the entire array!

To connect the pull back bracket to a full-range array module:

1. Assemble the array on the Array Frame or T-Bar Array Frame by following the instructions in this

manual and on pro.Bose.com.

2. Position the pull back bracket with the connection tabs facing up (toward the array). See Fig. 5.

3. Align the three connection tabs on the pull back bracket with the three connection points on the

bottom full-range array module (two in front, one in the rear center).

4. Insert two front pins (one on each side), then insert one rear pin to secure pull back bracket to module.

See Fig. 6.

5. Attach pullback cable(s) to the bracket using the included shackles.

6. Connect field wiring, test loudspeaker operation, and then elevate assembly to final operating position.

7. Adjust length of pullback cable attached to the pullback bracket as required for desired array tilt

angle.
