Installation
Section C: Pull Back Bracket Used to Suspend 1-2 Array Modules
The RMPULL pull-back bracket can also be used as a “mini-frame” to suspend 1 or 2 full-range modules.
WARNING:
Never use the RMPULL bracket as the primary support for more than 2 full-range modules.
When using the RMPULL bracket as the primary support frame, the following installation steps are recommended:
1.
Place the RoomMatch array module on the ground near the intended suspension point.
2.
With the tabs of the RMPULL bracket facing
downward
, align the 4 bolt holes of the tabs with the 4 bolt holes of the bottom mod-
ule sides plates. (Note: it may be helpful to use an alignment punch tool in the rear holes and then thread the bolts in the front holes
first.)
3.
Insert 4 bolts (2 per side) and finger tighten each until all bolts are installed.
4.
Tighten all 4 bolts with socket tool using torque of 35 to 40 foot-pounds (47 to 54 Newton-meters).
5.
If only 1 module is to be suspended using the RMPULL bracket, skip to step number 12.
6.
If 2 modules are to be suspended, connect shackles to the 4 mounting holes of the bracket and elevate module and bar assembly
to height slightly above that of 2nd module to be suspended.
7.
Place the 2nd RoomMatch array module on directly under the 1st module assembly.
8.
With 1 person per side, lift the 2nd module and guide the temporary handle pins into the alignment slots of the 1st (top) module
side plates.
9.
Holding the handles of the 1st (top) module stationary, pull forward on the handles of the 2nd (bottom) module to align the bolt
holes of both modules.
10. Insert 4 bolts (2 per side) and finger tighten each until all bolts are installed.
11. Tighten all 4 bolts with socket tool using torque of 35 to 40 foot-pounds (47 to 54 Newton-meters).
12. Remove temporary installation handles from top module.
13. Connect field wiring, test loudspeaker operation, and then elevate array assembly to final operating position.
Note:
An additional RMPULL bracket can be mounted on the bottom of the module to provide pitch adjustment from a third suspension
point.
