Important Safety Instructions

The lightning flash with arrowhead symbol within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated “dangerous voltage “ within the
product’s enclosure that may be of sufficient magnitude
to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the product.

power-supply cord or plug is damaged, liquid has been spilled, or objects have fallen into the device, the device has been exposed

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

15. WARNING: To reduce the risk of fire or electric shock, this device should not be exposed to rain or moisture and objects filled with

liquids, such as a vase, should not be placed on this device.

16. The PowerCON™ power output should not be used to daisy chain cabinets. To ensure correct operation, only run 1 cabinet off of a

15 to 20 amp circuit.

shock may result.

• Never operate this product or touch the power supply cord during an electrical storm, electric shock may result.

• Never exceed the power rating on the product when connecting equipment. Fire and/or property damage may result.

• Operate the product only with the voltage specified on the unit. Fire and/or electric shock may result if a higher voltage is used.

• Do not modify, kink, or cut the power cord. Do not place the power cord in close proximity to heaters and do not place heavy objects

on the power cord, including the product itself, doing so may result in fire or electrical shock.

• Ensure that the safety ground terminal is connected to a proper ground. Never connect the ground to a gas pipe as a catastrophic

disaster may result.

When The Product Is In Use

• Never place heavy objects on the product, causing it to fall and/or break, resulting in personal injury and property damage. In

addition, the product itself may fall and cause injury and property damage.

• Contact Atlas Sound for instructions on cleaning the inside of the unit. Large accumulations of dust inside the unit may result in heat

buildup and fire.

• Ensure that the power supply plug is securely plugged into the wall outlet. Never allow dust to accumulate on the power plug or

inside the wall outlet.

• When cleaning the unit or the unit is not to be operated for an extended period, unplug the power cord from the wall.

• Hearing Damage - CAUTION: All professional loudspeaker systems are capable of generating very high sound pressure levels. Use

care with placement and operation to avoid exposure to excessive levels that can cause permanent hearing damage.

• Suspension & Mounting - Suspension or “flying” speaker systems requires training and expertise. Improper rigging of a flying

speaker may result in injury, death, equipment damage, and legal liability. Installation must be carried out by fully qualified installers,

in accordance with all required safety codes and standards at the place of installation. A 5:1 design factor is a generally accepted

minimum standard. However, legal requirements for overhead suspension vary by municipality, please consult your local safety

standards office before installing any product. We also recommend that you thoroughly check any laws and bylaws prior to

installation. Loudspeakers flown in theaters, nightclubs, conference centers, or other places of work and entertainment must be

provided with an independent, correctly rated and securely attached secondary safety, in addition to the principle suspension
point(s). This secondary safety must prevent the loudspeaker from dropping more than (6") should the principle suspension

device fail. If you lack the skills, training, and proper ancillary equipment to fly a speaker system, do not attempt to do
so. For additional information regarding the suspension of loudspeakers or to purchase rigging materials, please contact our friends

at Adaptive Technologies Group,1635 E. Burnett St. Signal Hills, CA 90755. www.adapttechgroup.com Telephone [phone] and

AL123A-B

Owner’s Manual

Line Array System with EZAL Rigging

Applications

The AL123A-B large format line array system is designed for both fixed and touring professional audio installation applications where

clarity of speech and music are most important. The patented EZAL rigging included with the system enables quick and easy setup and

tear down from truck to stage in touring applications as the angle of the array can be adjusted on the fly.

• Corporate Speaking Events

• Live Music

• Sporting Arenas

• Large Indoor or Outdoor Facilities

• Ballrooms, Auditoriums, House of Worship

Overview

The AL123A-B is a single line array 3-way speaker enclosure that is designed to be either flown or ground stacked using four or more

units in a vertical array. The system includes dual 12" woofers, four 6" midrange drivers, and dual 1.4" high frequency compression

drivers powered by an integrated 3600-watt amplifier. A nominal horizontal coverage pattern of 120 degree is maintained, while the

vertical coverage will vary depending on the number of enclosures used and the splay angles that are chosen by using Atlas A-Line

patented EZAL rigging system. The pattern control will also depend on the length of the array. The integrated amplifier includes on-board

DSP that can be adjusted in real time via a network connection. The AL123A-B DSP is factory preset for flat response. Additional

adjustments can be made based on the number of units being used and the nature of the venue where they are used.

EZAL Rigging System - US Patent #7,261,180

The patented EZAL Rigging System is a precision engineered rigging system that is capable of precisely adjusting angles between

adjacent cabinets by up to 5 degrees while under load. The system can be ground stacked up to six cabinets or flown up to twelve

cabinets. Extreme caution and care by trained technicians is a requirement for successfully using this system. Only supplied

accessories and pins should be used with this rigging system. All pins should be fully inserted through the rigging and locked into place.

Check for proper seating of the pins by tugging and turning each pin after seating to ensure that the ball locking mechanism is fully

expanded on the backside of the rigging. The pins and rigging should be double checked by another member of the crew before the

system is raised. In all instances where this system is flown from a structure, the technician responsible for the hanging points should

be ETCP certified. For more information regarding ETCP certification visit http://etcp.plasa.org/cert_technicians/riggers.html.
