Mounting Panaray® LT Series lll Loudspeakers

Mounting Guidelines

WARNING: The Panaray® LT Series III loudspeakers must be attached to brackets or other mounting surfaces for permanent or seasonal use. Such mountings, typically in overhead locations, involve risk of personal injury if either the mounting system or the loudspeaker attachment fails. Installation of the mounting system must be performed in accordance with all applicable building codes including local codes. Consult the local authority having jurisdiction before installing this product.

The LT loudspeaker installation requires the use of either Bose® or non-Bose mounting products. While Bose Corporation cannot be held responsible for the proper design and use of non-Bose mounting systems, we offer the following informa- tion and guidelines for the permanent installation of your Panaray LT loudspeakers:

•Obtain your mounting system from a reputable manufacturer. Select a system design that works for your loudspeaker of choice and its intended use.

•Before using a custom-designed mounting system, have a licensed professional engineer review the design and fabrication for structural integrity and safety in the intended application.

•The threaded attachment points on the top, bottom, and sides of each loudspeaker have an SAE 3/8-16" thread with at least 18 usable threads.

•Lock washers or a locking compound intended for hand disassembly (such as Loctite 242) should be used for a vibration resistant assembly.

•Use a safety cable, separately attached to the cabinet, at a point not in common with the load bearing attachment points of the mounting system to the loudspeaker. This is recommended even if not required by local regulation. If you are unfamiliar with the proper design, use, and purpose of a safety cable, consult a licensed professional engi- neer or a rigging professional.

•Additional loudspeakers may be suspended below the Panaray LT loudspeaker provided that:

•It employs all 8 threaded-insert hang points on the top and bottom to fly and suspend the loudspeakers.

•The total weight of suspended loudspeakers and the Panaray LT loudspeaker does not exceed the working load limit (WLL) listed below:

3202® III Loudspeaker = 395 lb (179 kg)	6403 Loudspeaker = 454 lb (205 kg)	MB12 Loudspeaker = 350 lb (158 kg)
4402® III Loudspeaker = 299 lb (135 kg)	9403 Loudspeaker = 454 lb (205 kg)	MB 24 III Loudspeaker = 520 lb (236 kg)
9402TM III Loudspeaker = 261 lb (118 kg)	6400 Loudspeaker = 420 lb (190 kg)
9702® III Loudspeaker = 381 lb (173 kg)	9400 Loudspeaker = 420 lb (190 kg)

CAUTION: Use only graded hardware. Fasteners should be SAE Grade 5 or ASTM designation A354, Grade BC minimum. Unmarked machine fasteners should not be used for mounting system assembly, as there is no way to determine their physical properties. Do not use an M10 fastener; although it is very similar to an SAE 3/8-16’’, they are not interchangeable. M10 washers may be used in place of 3/8’’ washers.

CAUTION: The fasteners should be tightened using torque not to exceed 50 pounds/inch (5.6 Newton- meters). Over-tightening the fastener could result in irreparable damage to the cabinet and create an unsafe assembly.

CAUTION: The fastener should be long enough to engage no fewer than 16 threads of the attachment point. Using a fastener that is too short provides inadequate holding power and may strip the mounting threads, resulting in an unsafe assembly. Confirm that at least 16 full threads are engaged in your assembly.

CAUTION: Do not attempt to alter the threaded attachment points. Do not attempt to re-thread the attachment points to accommodate any other thread size or type; doing so will compromise the safety of the installation while permanently damaging the loudspeaker.
