Please Read Carefully Before Installing or Operating
• Read all instructions carefully
• Heed all warnings
• Assure that 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 "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 theatres, 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 ATM Group, Inc., 21000 S. Wilmington Avenue, Carson, CA 90810.

General considerations and hardware recommendations
CAUTION: The AH5040CD weights 81 pounds (36.7kg). A fall from almost any height could result in
serious injury or death. Assure that the speaker is firmly mounted to an object that can handle the weight
of the AH5040CD. Remember that wind will add considerable torque to the point of attachment. The
mounting surface the AH5040CD is being attached to should be able to handle five or more times the
weight of the AH5040CD (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 approximation of 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 AH5040CD to a solid surface use the proper bolts, washers and lock washers
(Grade 5 minimum). Do not substitute mismatched bolts and washers.
The AH5040CD 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 qualified structural/mechanical engineer for approval of the mounting
materials and methods.

Assure that the AH5040CD can be mounted in a manner that the sound pattern will be directed in the
desired direction without any physical interference. Note that the AH5040CD mounting bracket allows the
speaker to be tilted 50 degrees in either direction (100 degrees total). See illustration below.

Weep-holes (for drainage) are located on the same side as the input connectors. If the speaker is
tilted above parallel to the ground, the speaker should be installed with the weep holes down for water
drainage.

MOUNTING
CAUTION: Mounting the AH5040CD 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 AH5040CD 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 @ 12-1/8" OC spacing are recommended.
When using these mounting holes 1/2" (grade 5 hardware minimum) hardware should be used
with proper flat and lock washers. Remember to use thread- locking compound on all parts.
2. Use the dimensions noted on the above illustration to mark the points where the starting hole
should be drilled.
3. Choose appropriately sized bit and drill holes.
4. Attach speaker bracket, using bolt, flat washer, and lock washer as shown and re-attach
loudspeaker to bracket.
5. 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 AH5040CD and
secured to the mouning surface via approved, load rated hardware.

SUSPENDED INSTALLATION VIA EYEBOLTS (INCLUDED)
AND 1/4" DIAMETER WIRE ROPE
Note: Use of 1/4" load rated wire rope is suggested to provide a static working load limit of 1400
lbs(635kg) / moving load limit of 875lbs (397kg) per fly 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 AH5040CD 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 first 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 fittings & 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.
Eyebolt Working Load Limits

SPEAKER CABLE RECOMMENDATIONS AND CONNECTION INSTRUCTIONS
Wire Gauges (8-ohm operation)
For very short distance speaker cable runs (less than 25') #16-Guage, stranded, twisted pair speaker
cable may be used. For speaker cable runs between 25' and 75', #14-Guage, stranded, twisted pair
speaker cable is recommended. For speaker cable runs greater than 75' #12-Guage, stranded, twisted
pair speaker cable is necessary.
The AH5040CD uses (2) Speakon TM NL-4 connectors. Both connectors are paralleled with pins 1+ and
1- as the speaker input. Pins 2+ and 2- are paralleled to allow "daisy chaining" to other AH5040CD’s.
Check the labeling on the Speakon cable connectors for the Speakon wiring diagram.
The figure below shows the location of the access holes for the Speakon connectors.
ACCESS HOLES FOR
SPEAK-ON CONNECTORS
HOLE FOR
STRAIN RELIEF
The connection wiring should be routed through the access holes (as shown above) and attached to the
Speakon connectors. Allow an adequate service loop for this connection to allow tilt of the loudspeaker.
Weep-holes (for drainage) are located on the same side as the input connectors. If the speaker is
tilted above parallel to the ground, the speaker should be installed with the weep holes down for water
drainage.

Consult your amplifier owner’s manual to confirm power output at the rated impedance. Each AH5040CD
exhibits an 8 ohm (nominal) impedance.
(2) AH5040CD’s paralleled will present a 4 ohm load to the amplifier.
(3) AH5040CD’s paralleled will present a 2.66 ohm load to the amplifier.
(4) AH5040CD’s paralleled will present a 2 ohm load to the amplifier.
ATLAS SOUND speaker system specifications list RMS power handling. As a reference peak power =
RMS x 1.414.
These ratings should be considered in selecting the best amplifier to power the speaker system.
For general use, amplifier output should match or exceed the RMS rated power of the speaker system
(250 watts for the AH5040CD).
For increased headroom and dynamic reproduction, the amplifier’s output should match or exceed the
peak power rating of the speaker system (354 watts for the AH5040CD).
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, amplifier output may meet,
but should not exceed 2x the RMS power rating of the speaker system (500 Watts for the AH5040CD).
