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: These 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 Allen Products, Inc., 1635 E. Burnett St. Signal Hills, CA 90755.

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 firmly 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 five 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:

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 seven for mounting hole locations. When in doubt contact a qualified structural/mechanical engineer for approval of the mounting materials and methods.

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 38 " (16mm) diameter outer keyhole slots are recommended.
2. When using these mounting holes 12 " (grade 5 hardware minimum) hardware should be used with proper flat 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, flat 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 (two) of the drop forge eyebolts provided on the AH speaker and secured to the mounting surface via approved, load rated hardware.

Suspended Installation Via Eyebolts (Included)

Using 14 " Diameter Wire Rope

Technical line drawing of a mechanical component suspended by three hanging weights (no text or symbols)

Note: Use of 14 " load rated wire rope is suggested to provide a static working load limit of 1400 lbs (635kg) / moving load limit of 875 lbs (397kg) per fly point. 18 " cable is not recommended as load limits are reduced to 400 lbs (181kg) static 250 lbs (113kg) moving per flying point.

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 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.

Speaker Cable Recommendations And Connection Instructions

Wire Gauges (8Ω 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 efficiency 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 8Ω 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. The speaker should be installed angled slightly down for proper water drainage — in outdoor installations.

Amplifier Considerations

Consult your amplifier owner's manual to confirm power output at the rated impedance.

15' models: AH5040S, AH9040S, and AH6565S and other models used in 8Ω configuration. Each model exhibits an 8Ω (nominal) impedance.

(x2) AH models paralleled will present a 4Ω load to the amplifier.

(x3) AH models paralleled will present a 2.66Ω load to the amplifier.

(x4) AH models paralleled will present a 2 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 15" AH models, 200 Watts for the 12" models and 100 Watts for 8" models). 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 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, amplifier 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 amplifier will allow you to easily match required power ratings for Imost any installation. Visit www.AtlasSound.com for more details on this product.
