INSTALLATION INSTRUCTIONS

SAFETY INSTRUCTIONS

Please Read Carefully Before Installing or Operating

• Read all instructions carefully

• Heed all warnings

• Assure that the speaker is securely mounted

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 "fl ying" speaker systems requires training and expertise. Improper rigging of a fl ying
speaker may result in injury, death, equipment damage, and legal liability. Installation must be carried
out by fully qualifi ed 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 offi ce before installing any
product. We also recommend that you thoroughly check any laws and bylaws prior to installation.

Loudspeakers fl own 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 fl y 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
ATM Group, Inc.,1635 E. Burnett St. Signal Hills, CA 90755.

INSTALLATION INSTRUCTIONS

INSTALLATION VIA MOUNTING BRACKET (INCLUDED)

General considerations and hardware recommendations
CAUTION: AH series models weigh as much as 81 pounds (36.7kg) – model AH5040CD. A fall from

almost any height could result in serious injury or death. Assure that the speaker is fi rmly mounted to an
object that can handle the weight of the AH speaker. Remember that wind will add considerable torque
to the point of attachment. The mounting surface the AH speaker is being attached to should be able to
handle fi ve or more times the weight of the AH speaker (7x recommended for locations subject to high
wind forces).

Whenever the loudspeaker is mounted to a surface using the bracket, the installer must ensure that the
surface is capable of safely and securely supporting the load. The hardware employed must be safely and
securely attached both to the loudspeaker and the surface in question, using only the mounting holes. A
general rule for soft surface installations (wood beams) is to multiply the corresponding working load limit
by 75%: the result will be an approximate working load strength.

Use thread locking compound for all installations.
CAUTION: Mount the speaker such that the shear force is at a right angle to the mounting bolts, and

close to the connection, as shown:

TENSION FORCE

Lock Washer

SHEAR FORCE

Flat Washer

When mounting the AH speaker to a solid surface use the proper bolts, washers, and lock washers
(Grade 5 minimum). Do not substitute mismatched bolts and washers.

The AH speaker may be mounted to a pole or scoreboard. For such mounting, contact the light pole or
scoreboard manufacturer for proper instructions.

If mounting to another surface, such as a beam, see the diagram on page 7 for mounting hole locations.

When in doubt contact a qualifi ed structural/mechanical engineer for approval of the mounting
materials and methods.

INSTALLATION INSTRUCTIONS

Mounting

CAUTION: Mounting the AH loudspeaker requires two people, unless it is possible to safely clamp the

speaker in position for alignment before mounting.

The bracket may be removed from the speaker for installation convenience. When re-attaching speaker to
bracket be sure to tightly secure speaker mounting bolts. Thread locking compound should also be used
in this operation.

1. Choose the bracket mounting holes best suited for the surface you are mounting to. For best
stability the 5⁄8" (16mm) diameter outer keyhole slots are recommended.

2. When using these mounting holes 1⁄2" (grade 5 hardware minimum) hardware should be used
with proper fl at and lock washers. Remember to use thread- locking compound on all parts.

3. Use the dimensions noted on the illustration to mark the points where the starting hole should be
drilled.

4. Choose appropriately sized bit and drill holes.

5. Attach speaker bracket, using bolt, fl at washer, and lock washer as shown and re-attach
loudspeaker to bracket.

6. Secondary (safety) suspension point: Use a load rated cable or steel chain (capable of holding
the speaker should it come loose from the primary mounting point). This cable or chain assembly
should be attached to at least (2) of the drop forge eyebolts provided on the AH speaker and
secured to the mounting surface via approved, load rated hardware.

INSTALLATION INSTRUCTIONS

SUSPENDED INSTALLATION VIA EYEBOLTS (INCLUDED)

Using 1⁄4" Diameter Wire Rope

Note: Use of 1⁄4" load rated wire rope is suggested to provide a static working load limit of 1400lbs (635kg)

and moving load limit of 875lbs (397kg) per point. 1⁄8" cable is not recommended as load limits are reduced
to 400lbs (181kg) static, and 250lbs (113kg) moving.

Considerations for overhead suspension using AH Series eyebolts and wire rope:

1. Always apply the load to the eye in the plane of the eye.

2. Always use shoulder eyebolts for angular lifts.

3. Always tighten eyebolts securely against the load.

4. Apply fi rst load to test the assembly. This load should be of equal or greater weight than the loads
expected in use.

5. Use wire rope compression fi ttings & thimbles whenever possible and prepare terminations only
as instructed by the manufacturer.

6. If wire rope clips are used, check and retighten to the manufacturer's recommended torque.

SPEAKER CABLE RECOMMENDATIONS AND CONNECTION INSTRUCTIONS

Wire Gauges (8 Ohm operation)

For very short distance speaker cable runs (less than 25') #16-gauge, stranded, twisted pair speaker
cable may be used. For speaker cable runs between 25' and 75', #14-gauge, stranded, twisted pair
speaker cable is recommended. For speaker cable runs greater than 75', #12-gauge, stranded, twisted
pair speaker cable is necessary. For runs exceeding 150', please contact tech support for proper wire
gauge or other installation solution using the Atlas Sound AF140 autoformer.

15" models AH5040S, AH9040S, and AH6565S input connections are provided on a convenient recessed
terminal block located on the bottom of the loudspeaker. This terminal block includes a clear weather
resistant cover which should be re-installed after terminating the speaker cabling to prevent corrosion in
outdoor applications.

8" & 12" models include a built-in, high effi ciency 60 Watt 70.7V transformer. 7.5, 15, 30, and 60 Watt
taps are available on a convenient recessed terminal block located on the bottom of the loudspeaker.
A removable jumper and additional pole on the terminal block is included for 8 Ohm direct coupled
operation. This terminal block includes a clear weather resistant cover which should be re-installed after
terminating the speaker cabling to prevent corrosion in outdoor applications.

Allow an adequate service loop for this connection to allow tilt of the loudspeaker. If the speaker is tilted
above parallel to the ground, the speaker should be installed angled slightly down for water drainage — in
other words, the product should not be installed tilted upwards!

AMPLIFIER CONSIDERATIONS

Consult your amplifi er owner’s manual to confi rm power output at the rated impedance.

15" models: AH5040S, AH9040S, and AH6565S and other models used in 8 Ohm confi guration

Each model exhibits an 8 Ohm (nominal) impedance.
(x2) AH models paralleled will present a 4 Ohm load to the amplifi er.
(x3) AH models paralleled will present a 2.66 Ohm load to the amplifi er.
(x4) AH models paralleled will present a 2 Ohm load to the amplifi er.

ATLAS SOUND speaker system specifi cations list RMS power handling.
As a reference peak power = RMS x 1.414.
These ratings should be considered in selecting the best amplifi er to power the speaker system.
For general use, amplifi er output should match or exceed the RMS rated power of the speaker system:
(250 Watts for the 15" AH models, 200 Watts for the 12" models and 100 Watts for 8" models).
For increased headroom and dynamic reproduction, the amplifi er’s output should match or exceed the
peak power rating of the speaker system (354 Watts for the 15" AH models, 283 Watts for 12" models
and 141 Watts for 8" models).

In situations where experienced professionals are operating the speaker system with proper limiting
and frequency control devices inserted into the signal path and adjusted properly, amplifi er output may
meet, but should not exceed 2x the RMS power rating of the speaker system (500 Watts for the 15" AH
models, 400 Watts for 12" AH models, and 200 Watts for 8" AH models).

Utilizing the Atlas Sound model CP700 power amplifi er will allow you to easily match required power
ratings for most any installation. Visit www.AtlasSound.com for more details on this product.
