Disclaimer:

LOUD Technologies Inc. continually engages in research related to product improvement. New material,

production methods, and design renements are introduced into existing products without notice as a routine

expression of that philosophy. For this reason, any current LOUD Technologies Inc. product may differ in

some respect from its published description, but will always equal or exceed the original design specications

unless otherwise stated.

WARNING: Installation should only be done by experienced licensed professionals. Improper installation may result in damage

to the equipment, injury or death. Make sure the loudspeakers are installed in a stable and secure way in order to avoid any conditions

that may be dangerous for persons or structures.

Before suspending the loudspeaker(s), make all of the necessary calculations to ensure that all of the components are used within their

nominal work load range. Remember that the weakest component determines the safety level of the entire installation. Additionally,

EAW Resolution software should be downloaded, installed and utilized to help make these decisions:

Introduction

HDA and HD1801 loudspeakers may be suspended below a hoisted FB221 Flybar. The ybar is also used as a base for HDA

loudspeakers when arrayed on the oor. The HD1801 is placed directly on the oor with no need for the FB221 Flybar.

These instructions will rst explain how to suspend loudspeakers from the FB221 Flybar, then explain how to use the ybar as a base

on which to stack an HDA array. Note that a foot assembly must be attached to the ybar before using the FB221 Flybar as a ground

stack base. Installation is explained in the second half of these instructions.

Before installing and using this product, please read these instructions carefully and keep them on hand for future reference.

Additionally, refer to the product manual(s) for detailed product-specic information. Failure to follow the precautions in these

documents may result in injury or damage to the loudspeaker, the FB221 Flybar, or even you!

8. Ground stacking HDA loudspeakers on the

FB221 Flybar:

A maximum of three (3) HDA loudspeakers may be stacked

and locked on an FB221 Flybar. Only one (1) person is required

to stack the rst two (2) HDA loudspeakers on the ybar.

a. Position an HDA

loudspeaker on the ybar

so its two (2) side rigging

tubes are aligned above the

xed latches in the ybar.

b. Remove the two (2)

side quick release pins

from the ybar. They may

be inserted in the latch

through holes for storage.

c. Remove the two (2)

side quick release pins

from the sides of the HDA

loudspeaker; the latches

will drop and rest atop the

ybar's xed latches.

d. Align the holes in the HDA's latches and the holes

immediately above the ybar's latches. Lock the loudspeaker in

position by fully inserting the quick release pins removed in the

proceeding step.

e. Stack additional HDA loudspeakers as required. Note that

the HDA only has two (2) rigging tubes and latches. This

procedure is similar to those outlined in sections 3b through 3d.

9. Ground stacking an HDA / HD1801

loudspeaker array:

The FB221 Flybar is

not required for this

application, as the HD1801

(with the ACC-R180S

Rigging Kit) is used as the

ground stack base.

A limit of three (3)

HDA loudspeakers may

be stacked on up to

two (2) HD1801

subwoofers. Two (2)

people are required to lift

and stack the

loudspeakers in a mixed

array. Loudspeaker

stacking and locking

procedures outlined in

sections 3a through 3d in

these instructions should

be followed.

6. The FB221 Ground Stack Foot Kit:

The FB221 Flybar requires the use of a supplied Ground Stack

Foot Kit to ground stack HDA loudspeakers. This kit is made up

of the following parts:

Flybar:

The Ground Stack Foot is mounted to the underside of the

FB221 Flybar. The ybar is correctly oriented when the hole

numbers are right side up and the ybar's xed latches point

down. The latches serve as additional feet in a ground stack

application.

a. With the edge of the foot facing front, t the two (2) arms of

the foot on each side of the ybar.

b. Align the two (2) holes in the foot to the holes in the ybar.

c. Insert both screws with their lock washers through the holes

in the foot and ybar. Then thread the screws into the internal
