1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with a dry cloth.

7. Do not block any ventilation openings. Install in accordance with the

manufacturer’s instructions.

8. Do not install near any heat sources such as radiators, heat registers,

stoves, or other apparatus (including ampliﬁers) that produce heat.

9. Do not defeat the safety purpose of the polarized or grounding-type

plug. A polarized plug has two blades with one wider than the other.

A grounding-type plug has two blades and a third grounding prong.

The wide blade or the third prong are provided for your safety. If the

provided plug does not ﬁt into your outlet, consult an electrician for

replacement of the obsolete outlet.

10.

Do not overload wall outlets and extension cords as this can result in a

risk of ﬁre or electric shock.

11.

Protect the power cord from being walked on or pinched particularly at

plugs, convenience receptacles, and the point where they exit from the

apparatus.

12.

Only use attachments/accessories speciﬁed by the manufacturer.

13.

Use only with a cart, stand, tripod, bracket, or

table speciﬁed by the manufacturer, or sold with

the apparatus. When a cart is used, use caution

when moving the cart/apparatus combination to

avoid injury from tip-over.

14.

Unplug this apparatus during lightning storms or

when unused for long periods of time.

15.

Refer all servicing to qualiﬁed service personnel. Servicing is required

when the apparatus has been damaged in any way, such as power-

supply cord or plug is damaged, liquid has been spilled or objects have

fallen into the apparatus, the apparatus has been exposed to rain or

moisture, does not operate normally, or has been dropped.

16.

This apparatus shall not be exposed to dripping or splashing, and no

object ﬁlled with liquids, such as vases or beer glasses, shall be placed

on the apparatus.

17.

This apparatus has been designed with Class-I construction and must

be connected to a mains socket outlet with a protective earthing

connection (the third grounding prong).

18.

The MAINS plug or an appliance coupler is used as the disconnect

device, so the disconnect device shall remain readily operable.

19. NOTE: This equipment has been tested and found to comply with the

limits for a Class B digital device, pursuant to part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against

harmful interference in a residential installation. This

equipment generates, uses, and can radiate radio frequency energy

and, if not installed and used in accordance with the instructions, may

cause harmful interference to radio communications. However, there is

no guarantee that interference will not occur in a particular installation.

If this equipment does cause harmful interference to radio or television

reception, which can be determined by turning the equipment off and

on, the user is encouraged to try to correct the interference by one or

more of the following measures:

• Reorientorrelocatethereceivingantenna.

• Increasetheseparationbetweentheequipmentandthe

receiver.

• Connecttheequipmentintoanoutletonacircuitdifferentfrom

that to which the receiver is connected.

• Consultthedealeroranexperiencedradio/TVtechnicianfor

help.

CAUTION: Changes or modiﬁcations to this device not expressly

approved by LOUD Technologies Inc. could void the user's authority to

operate the equipment under FCC rules.

20.

This apparatus does not exceed the Class A/Class B (whichever is

applicable)

limits for radio noise emissions from digital apparatus as

set out in the radio interference regulations of the Canadian Department

of Communications.

ATTENTION — Le présent appareil numérique n’émet pas de bruits

radioélectriques dépassant las limites applicables aux appareils

numériques de class A/de class B (selon le cas) prescrites dans le

réglement sur le brouillage radioélectrique édicté par les ministere des

communications du Canada.

21.

Exposure to extremely high noise levels may cause permanent hearing

loss. Individuals vary considerably in susceptibility to noise-induced

hearing loss, but nearly everyone will lose some hearing if exposed to

sufﬁciently intense noise for a period of time. The U.S. Government’s

Occupational Safety and Health Administration (OSHA) has speciﬁed

the permissible noise level exposures shown in the following chart.

According to OSHA, any exposure in excess of these permissible limits

could result in some hearing loss. To ensure against potentially

dangerous exposure to high sound pressure levels, it is recommended

that all persons exposed to equipment capable of producing high

sound pressure levels use hearing protectors while the equipment

is in operation. Ear plugs or protectors in the ear canals or over the

ears must be worn when operating the equipment in order to prevent

permanent hearing loss if exposure is in excess of the limits set forth

here:

HD1221

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.

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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.
