USER MANUAL PM4FA-B Atlas Sound

Please Read Carefully Before Installing or Operating

• Read all instructions carefully
• Heed all warnings
  • Assure that the speaker is securely mounted

Hearing Damage

CAUTION:

This professional loudspeaker systems is 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.

• Always assure power is off to amplifiers before making any connections
• Assure that all electrical equipment is properly grounded
- Keep instructions for future reference

Installation Via Mounting Cables (Included)

General considerations and hardware recommendations

CAUTION: PM series models weigh as much as 21 pounds (7.9kg) – model PM8CX. 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 PM speaker. The mounting surface the PM speaker is being attached to should be able to handle five or more times the weight of the PM speaker

The hardware employed must be safely and securely attached both to the loudspeaker and the structure 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 approximate working load strength. Use thread locking compound for all installations.

CAUTION: Mounting the PM loudspeaker may require two people.

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

1. Remove the 3 top cover mounting screws, loosen the 2 side top cover screws rotate the top cover counterclockwise, and pull up to remove the top cover. (Fig 1 and 2)
2. Locate suitable support structure in the area the speaker is to be installed.
3. Route the bare end of the main support cable though the included clamp, then around the mounting structure, and back through the clamp. (Fig 3 and 4)
4. Adjust the cable length in the clamp so that the eyelet end of the cable is at the final height above the floor. (Fig 5)
5. (For PM8) Route the eyelet end of the main support cable through the top cover of the PM speaker, attach the included carabiner clip to the eyelet and the large mounting hole on the back of the PM speaker. (Fig 6a) (For PM4) Route the eyelet end of the main support cable through the top cover of the PM speaker, attach the eyelet to the large mounting hole on the back of the PM speaker using included mounting screw. (Fig 6b)
6. Repeat steps 1-4 for the safety cable and attach it the one of the smaller mounting holes on the support plate of the PM speaker with the included mounting screw. (Fig 6)
7. Route the speaker cable through the top cover and connect to the appropriate terminals.
8. Position the top cover over the side cover screws and rotate the cover clockwise to align the top cover mounting screw holes. Reinstall the 3 mounting screws, tighten and tighten the side cover screws.
9. Slide the top hole plug over the main support cable, safety cable, and speaker cable using the opening on the side of the plug. Then slide the plug down the cable and into the top cover hole. (Fig 7 and 8)

Note: If the speaker is being installed outdoors, seal plug with RTV silicone to prevent moisture from entering speaker.

Applications

The Atlas Sound PM4FA features the familiar response and dispersion of Atlas Sound's model FA134 high performance 4" Strategy Series driver. This loudspeaker is the same FA Series device used in Atlas Sound's successful model FAP42T ceiling speaker package. Mounted down-firing in an attractive enclosure, the PM4FA provides natural sounding, wide coverage for low height installations while retaining impressive full range frequency response for both music and paging applications.

Attaching a PM4FA to most over head surfaces is a breeze. For open beam ceilings a 3 meter cable kit is included with a self gripping ferrule system. If down pipe installation from hard ceiling material is required, any 34'' ceiling fan installation kit may be utilized. These kits are readily available under the FANTEC ^™ brand from home improvement stores with various down pipe length options to provide installation ease regardless of ceiling angle (Up to 45°).

Either installation solution is discreetly implemented via the PM series innovative top cover design concealment cap. This "cap" includes a cable access plug that is easily removed for down pipe mounting. The cover also completely conceals the speaker cable terminations and the suspension anchor points.

Several packages are offered to suit various coverage pattern and installation scenarios. For low ceilings, Atlas Sound offers a discrete enclosure system containing an ultra wide coverage 4" FA series driver. For higher ceiling applications, Atlas Sound PM series answers the need for a variety of budget and performance requirements with three different 8" driver options, factory assembled into in a larger yet still attractive pedant style enclosure.
