Frequently Asked Questions - PM8GD-W Atlas Sound

What is the maximum weight capacity for the mounting hardware?

The mounting surface should support at least 5 times the weight of the speaker. The PM8 model weighs approximately 21 lbs, so the structure must handle over 105 lbs. For soft surfaces, reduce working load by 25%.

How do I install the PM8GD-W using the included cables?

Remove top cover, route main support cable through clamp and around support structure, adjust height, attach eyelet to carabiner and large mounting hole. Repeat for safety cable to smaller hole. Connect speaker cable, replace cover, and slide plug.

Can I install the speaker outdoors?

Yes, but you must seal the top hole plug with RTV silicone to prevent moisture entry. Ensure all connections are weatherproofed.

What should I do if there is no sound from the speaker?

Check that power is on to all equipment, verify routing and volume controls, and inspect for loose connections from source to speaker terminals.

How do I troubleshoot distortion at high volumes?

Distortion may indicate the amplifier or speaker is overdriven. Ensure power to the speaker is within limits and reduce amplifier gain to avoid clipping.

Is a secondary safety cable necessary?

Yes, always use an independent safety cable rated for the load. It must prevent the speaker from falling more than 6 inches if the primary suspension fails.

What tools are needed for installation?

You will need screwdrivers (for top cover screws), wrench for clamp, and possibly thread locking compound. For down pipe installation, standard ceiling fan hardware tools.

How do I mount the speaker using a down pipe?

Use 3/4 inch diameter ceiling fan hardware (not included). Attach top cover to down pipe, install safety screw through side, route safety cable through pipe, and connect as with cables.

What does the model number PM8GD-W signify?

PM stands for Pendant Mount, 8 is driver size (8 inches), GD may indicate a specific variant (possibly grille/design), and W stands for white color.

Can I hang the speaker from a wooden beam?

Yes, use appropriate hardware with a 5:1 safety factor. For soft wood, multiply the working load limit by 75% and use thread locking compound.

USER MANUAL PM8GD-W 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

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.
