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

AH SERIES STADIUM SUBWOOFER
SYSTEMS
Thank you for your purchase of an Atlas Sound AH
Series loudspeaker system. We have designed this
product to be a reliable and versatile solution to your
needs for years to come.
The AHSUB15-BSG subwoofer system features high
output and amazing low frequency response for indoor
and outdoor applications including football stadiums,
sports arenas, baseball elds, and large auditoriums.
Unit features an efcient low frequency woofer loaded
into a durable, weather resistant, rear ring enclosure
FEATURES
• Impressive efciency rating of 103dB 1Watt/1Meter
makes the AH series a perfect choice for low
frequency augmentation of high energy music
playback at sporting events.
• Weather & rodent resistant. Rear ring woofer cavity
and mesh screen over the enclosure front protects
the speaker from weather and/or rodent damage.
• Easy installation. Secure surface mounting or
suspension installation is possible via the integral
forged eyebolts.

GROUND INSTALLATION
General considerations and hardware recommendations
Excellent results may be achieved by mounting the AHSUB15-BSG under bleacher seating. Electronic
delay is suggested to approximate time alignment of full range speakers with subwoofer(s) to the listener
locations.
CAUTION: The AHSUB15-BSG weighs 181 pounds (82.1kg). A fall from almost any height could result in
serious injury or death. Assure that the speaker is rmly mounted to an object that can handle the weight.
For on ground installation a 36" square 2" thick (minimum) concrete pad is suggested. If this pad is to be
poured concrete, rebar anchors are suggested to allow chain or cable securing of the AHSUB15-BSG for
theft resistance.
Overhead Suspension Installation
Remember that wind will add considerable torque to the point of attachment. The mounting surface the
speaker is being attached to should be able to handle ve or more times the weight of the AH speaker (7x
recommended for locations subject to high wind forces).
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. 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.

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 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 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
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.
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.
Allow an adequate service loop for this connection to allow tilt of the loudspeaker. If the speaker is tilted
above parallel to the ground, water may collect in the speaker cabinet causing damage — the product
should not be installed tilted upwards!

AMPLIFIER CONSIDERATIONS
Consult your amplier owner’s manual to conrm power output at the rated impedance.
The AHSUB15-BSG exhibits an 8 Ohm (nominal) impedance.
(x2) AHSUB15-BSG paralleled will present a 4 Ohm load to the amplier.
(x3) AHSUB15-BSG paralleled will present a 2.66 Ohm load to the amplier.
(x4) AHSUB15-BSG paralleled will present a 2 Ohm load to the amplier.
ATLAS SOUND speaker system specications list RMS power handling.
As a reference, peak power = RMS x 1.414.
These ratings should be considered in selecting the best amplier to power the speaker system.
For general use, amplier output should match or exceed the RMS rated power of the speaker system
(250 Watts).
For increased headroom and dynamic reproduction, the amplier’s output should match or exceed the
peak power rating of the speaker system (354 Watts).
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, amplier output may meet,
but should not exceed 2x the RMS power rating of the speaker system (500 Watts).
Utilizing the Atlas Sound model CP700 power amplier will allow you to easily match required power
ratings for most any installation. Visit www.AtlasSound.com for more details on this product.
