22.Rigging Precautions: When mounting or suspending loudspeaker enclosures, it is essential that load ratings, rigging techniques, and special safety considerations be appropriate for the installation. Use only the mounting/rigging points on the loudspeaker enclosure intended for this purpose. The user must determine the load requirements, dynamic loading, and any other contributing factors affecting the loudspeaker installation. The user must determine the proper design factor for specific applications and the required load rating of the connection to structure. Comply with all applicable federal, state, and local regulations.

We strongly recommend the following rigging system practices:

•Documentation: Thoroughly document the mounting/rigging design with detailed drawings and parts lists.

•Analysis: Have a licensed structural engineer or other qualified professional review and approve the mounting/rigging design before its implementation.

•Installation: Use personnel experienced and qualified for mounting/rigging loudspeakers in accordance with and in compliance with all federal, state and local regulations.

DANGER: Loudspeakers should be mounted or suspended only

by persons with knowledge of the proper hardware and rigging techniques. When stacking or pole-mounting loudspeakers, be

sure that they are stabilized and secured from falling over or being accidentally pushed over. Failure to follow these precautions may result in damage to the equipment, personal injury, or death.

Introduction

The HD1221 Powered Loudspeaker represents a major step into portable high-definition live sound, providing precise, articulate full-range sound at the high-output levels demanded of modern PA systems. Two Class-D Fast Recovery™ amplifiers efficiently drive 1200 Watts of total system power, providing maximum output with minimal distortion. True high-definition sound is possible thanks to an arsenal of technological innovations including patented acoustic correction processing that was previously only available on high- end stadium touring systems. This complex processing, along with a phase-coherent electronic crossover and transducer time-alignment provide unparalleled acoustic accuracy that has to be heard to be believed.

The HD1221 features system tuning, a 12” neodymium woofer and a 1.75” heat-treated titanium compression driver, custom designed by the award winning engineering team at EAW, delivering the ultimate in both quality and performance.

A custom rotatable horn by Martin Audio, three selectable voicing modes and extensive protection circuitry complete this ultra-portable, powerful HD system that may be used as the house PA or as monitors for the band.

All of these high-end components are housed in a rugged, all-wood enclosure that not only protects, but allows for multiple mounting options including flying and pole mounting. The HD1221 brings high-definition sound to the world of portable PA systems.
