To prepare the system before the installation:
1. Prepare the power and audio cables required for the installation.
2. Set the appropriate preset and DSP functions for the M-F3A FS subwoofer/s to deploy.
3. If applicable and depending on the number of boxes in the array, set the same "LINE UNITS" on
each of the M-F3A or M-F3A PRO units to use. Also, set the "LEVEL" control to the same position
on all the boxes.
4. For all the products and units to use, turn the power switch to the ON position.
To deploy a line array composed by subwoofers:
5. Connect the M-F3A FS BF bumper frame to the hoist chain/s using appropriate shackle/s in the
hole/s selected for the desired tilting. See figure 16.
6. Lift the bumper frame to a comfortable height and attach the first M-F3A FS subwoofer.
With the security pins, link the two front points of the first unit, to the front points of the frame.
7. Lock the upper rear part of the subwoofer by fastening the top security pins with the rear
releasable bars of the M-3A FS BF bumper frame. See figure 16.
8. Lift the bumper frame to a comfortable height and release the rear deployable bars of the first
subwoofer. Fix them in the upper hole, leaving most of their length outside.
9. Attach the second subwoofer below the first one. With the security pins, link the two front points
of the new unit, to the front points of the first one.
10. Lock the rear part of the new subwoofer by fastening the top security pins with the rear releasable
bars of the first one. Pick the right holes to set the desired splay angle.
11. Connect properly the power and audio cables for the units added.
12. Repeat steps 7 to 10 until all the subwoofers are suspended.
To add a line array of M-F3A or M-F3A PRO units under a flown M-F3A FS subwoofer:
4. Lift the bumper frame to a comfortable height and release the bars in the rear of the subwoofer.
Fix them in the middle hole, where half of their length is exposed.
5. Attach the M-F3A 34 adapter by inserting the deployable bars of the subwoofer, in the outermost
slots of the adapter. Fasten it locking its two security pins through the bars.
6. Add the first M-F3A or M-F3A PRO unit by attaching the two upper front points, to the lower front
points of the subwoofer.
7. Release the rear deployable bar of the new unit. Secure the box in the back by linking its rear
rigging piece with the moving bar in the M-F3A 34 adapter. Lock the security pin of the box in the
hole for the 0° angle.
8. Connect properly the power and audio cables for the first unit.
9. Add the second M-F3A or M-F3A PRO unit below the first one. Link its top rigging points with the
bottom points of the first one.
10. Unfold the moving part in the rear of the second box.
11. Connect the rear rigging piece of the second box with the deployable bar of the first one. Lock the
security pin of the new box in the correct hole to set the desired splay angle.
12. Connect properly the power and audio cables for the unit added.
13. Repeat steps 9 to 12 until the whole system is suspended and connected.
14. Before hoisting the line array to the final position, inspect thoroughly:
a. Bumper frame: Check the connection of the hoist chain and the first unit.
b. M-F3A 34 adapter: Check the connection of the last M-F3A subwoofer and the first M-F3A or
M-F3A PRO unit.
c. Rigging points and security pins: Be sure they all are correctly locked in place.
d. Splay angles: Verify the values established are correct.
e. Connections: Review the proper power and audio signal flow between boxes.
f. Units configuration: Double-check that all the units are turned ON, the preset selected for the
subwoofers, and that the M-F3A or M-F3A PRO units have all the same "LEVEL" and "LINE
UNITS" values.
To unmount the system, repeat the previous steps in inverse order respecting all the safety instructions
mentioned before.
