Mechanical Installation

Cables and chains attached to the eyebolts and
directly to a center lifting point, as shown in the
"Acceptable" example in Figure 9 , can create a
dangerous lateral force on the eyebolts and may
cause the eyebolts to fail. The smaller the angle
between the cable and the top of the cabinet,
the lighter the cabinet must be to safely lift it. If this
method must be used, ensure a minimum angle
between the chain and cabinet of at least 45°.
Do NOT attempt to lift the cabinet if the angle is
less than 45°. Exceeding load angles or weight limits
could cause the bolts in the cabinet to buckle,
resulting in serious damage to the equipment or injury
to personnel. Also, loads should be applied directly in
the plane of the eyebolt as shown in Figure 10 .
Note: Daktronics assumes no liability for damages resulting from incorrect setup or lifting
methods. Eyebolts are intended for lifting only. Do not attempt to permanently
support the cabinet by the eyebolts or eyebolt holes.
If installers remove the eyebolts, use 1/2" bolts to plug the holes.
Mount the Cabinet
Reference Drawings:
Shop Drawing; Sound System; 1500HD ............................................................ DWG-752494
The sound cabinet will be mounted atop a frame that must be certified by a structural
engineer. To mount the cabinet in place, position it on the structure where it is to
be mounted. Weld the cabinet’s bottom members to the structure at the locations
indicated on the shop drawing. Refer to DWG-752494 in Appendix A for mounting
requirements.
Aim the Speakers
Tools Required: 9/16” wrench/socket @2
Reference Drawings:
Mid/High Speaker Adjustment Chart; 1500HD ................................................ DWG-913590
Once the cabinet has been mounted in place, it may be necessary to adjust the
direction of the speakers for the individual facility. DWG-913590 in Appendix A provides
speaker aiming instructions as well as recommended angles to position the speakers,
based on the cabinet’s location in relation to the seating area(s).
