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.

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qualied
professional review and approve the mounting/rigging design
before its implementation.
• Installation:Usepersonnelexperiencedandqualied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.
