Rigging

HD1221s may be individually flown horizontally or vertically using M10 x 1.5 x 37 mm forged shoulder eyebolts.

WARNING: Installation should only be done by an experienced technician. Improper

installation may result in damage to the equipment, injury or death. Make sure that the loudspeaker is installed in a stable and secure way in order to avoid any conditions that may be dangerous for persons or structures.

WARNING: The cabinet is suitable for rigging via its fly points. NEVER attempt to suspend

the HD1221 by its handles.

Rigging Design Practices

Rigging a loudspeaker requires determining:

1.The rigging methods and hardware that meet static, shock, dynamic, and any other load requirements for supporting the loudspeaker from structure.

2.The design factor for and the required WLL

(Working Load Limit) for this support.

Mackie strongly recommends the following rigging practices:

1.Documentation: Thoroughly document the design with detailed drawings and parts lists.

2.Analysis: Have a qualified professional, such as a licensed Professional Engineer, review and approve the design before its implementation.

3.Installation: Have a qualified professional rigger do the installation and inspection.

4.Safety: Use adequate safety precautions and

back-up systems.

Rigging Hardware and Accessories

Rigging Mackie loudspeakers will invariably require hardware not supplied by Mackie. Various types of load-rated hardware are available from a variety of third-party sources. There are a number of such companies specializing in manufacturing hardware for, designing, and installing rigging systems. Each one of these tasks is a discipline in its own right. Because of the hazardous nature of rigging work and the potential liability, engage companies that specialize in these disciplines to do the work required.

Mackie does offer certain accessory rigging items, primarily for attachment to the hardware integral with the loudspeaker. Some items, such as eyebolts and U-brackets, may be used with a variety of products. While these accessories are intended to facilitate installation, the wide variety of possible installation conditions and array configurations do not permit Mackie to determine their suitability or load rating for any particular application.

Mackie is not in the business of providing complete rigging systems, either as designers, manufacturers, or installers. It is the responsibility of the installer to provide a properly engineered, load-certified rigging system for supporting the loudspeaker from structure.

Rigging Notes

The HD1221’s intergral mounting points are designed to support only the weight of their own loudspeaker with suitable, external hardware. This means that each HD loudspeaker must be supported independently of any other HD loudspeaker and any other loads.

A minimum of two rigging points must be used to hang an HD1221. More may be used for creating the desired hanging angle as shown in the illustrations on the following page. All mounting points are fully load bearing so any two may be used for rigging; no mounting points are restricted to angle control only.
