Precautions

AVOID EXCESSIVE HEAT, HUMIDITY, DUST AND VI-

BRATION

When choosing a location for your speakers, avoid the following:

•Direct sunlight, high temperatures (such as near heaters), or excessively low temperatures.

•High humidity.

•Areas subject to excessive dust accumulation and vibration.

•Non-level or unstable surfaces.

HOW TO POWER UP YOUR SOUND SYSTEM

To avoid damage to your speakers and other parts of your system, when you turn on your system, ALWAYS turn the power amp on last! This will avoid loud, damaging pops that will annoy your audience, and blow your speakers. When you power down, the amplifier should ALWAYS be turned off first to avoid the same problems.

To protect your speakers

When choosing a power amplifier to use with your speakers, make sure that its power output matches the speakers’ power capacity (refer to the Specifications on page 6). Even if the amplifier’s power output is lower than the speakers’ PGM (program) power capacity, the speakers may be damaged when clipping of a high input signal occurs.

The following may cause damage to speakers:

•Feedback caused when using a microphone.

•Continuous high sound pressure level produced by electronic instruments.

•Continuous high-power output distorted signals.

•Popping noises caused by turning on equipment, or by connecting or disconnecting system components while the amplifier is turned on.

MAKE SURE THE POWER IS OFF BEFORE MAKING

OR REMOVING CONNECTIONS

Always turn the power switches of system components OFF prior to connecting or disconnecting cables. Failure to do so may result in damage to speakers as well as to connected equipment.

DISCONNECT CABLES BEFORE MOVING THE SYS-

TEM

To prevent short circuits or breakage of cables, always disconnect cables prior to moving system equipment.

MATCH CONNECTOR POLARITY

When using two or more speaker systems, be sure match the polarity (+/–) of the speaker system connectors to those at the amplifier. If the polarities do not match, the sounds produced by the speakers will interfere with each other, making it impossible to achieve a well-balanced sound field.

KEEP THIS OWNER’S MANUAL IN A SAFE PLACE

FOR FUTURE REFERENCE

Poly Switch

All full-range loudspeakers are fitted with a self-reset- ting poly switch that protects the high-frequency driver from damage caused by excessive power.

If a loudspeaker cabinet loses high-frequency output, immediately remove power from the unit and wait for two to three minutes. The should allow the poly switch to reset. Re-apply power and check the performance of the high-frequency driver before continuing with the power reduced to a level that does not cause the poly switch to interrupt the signal.

On the SW118IV sub woofer, the Poly Switch protects the woofer and a similar routine should be followed if its output is lost.

This product, when used in combination with amplification and/or additional loudspeakers, may be capable of producing sound levels that could cause permanent hearing loss.

DO NOT operate at high volume levels or at a level that is uncomfortable. If you experience any discomfort or ringing in the ears, or suspect an hearing loss, you should consult an audiologist.

CAUTION!

The following five models can be mounted on speaker stands: S112IV, S115IV, SM10IV, SM12IV SM15IV. The use of Ultimate Support Systems, Inc. Model TS-30 or TS33 speaker stands is recommended.

•Use only ONE speaker per stand.

•The loudspeakers and stands must always rest upon a solid, level surface.

•Improper installation or usage could result in the loudspeaker falling and causing injury.

•The top tube of the TS-30 and TS-33 speaker stands has a diameter of 1-1/2", but is tapered to 1-3/8" at the top to fit in the mounting holes on the five models named. If you should remove the top tube from a stand, be sure to insert it with the narrow end up when reassembling.

The SW118IV subwoofer has a metal socket to allow mounting of a satellite speaker. Do not use a pole longer than 56".

SPEAKER HANDLES

The handles on your speakers are for transportation. They are not designed for suspension or hanging. Only the “A” versions of these speakers are designed for suspension. Please consult a qualified engineer for proper hanging techniques.

ATM Fly-Ware

Model S115IVA-OAK only

These speakers are supplied with ATM Fly-Ware rigging hardware installed. The following notes explain how to prepare these speakers for suspension.

IMPORTANT! This material does not explain how to

suspend speakers.

To properly suspend any speaker, a knowledge of structural engineering and structural rigging is REQUIRED. Suspending loudspeakers requires special tools and techniques. Do not attempt to suspend any speaker system unless you have received specific training to do so.

The improper installation of flying speakers can result in bodily injury or death.

Always consult a licensed engineer to verify the design of any suspended system. In addition, please follow these safety steps:

•Use only hardware specifically designed for rigging applications.

•Always use an independent safety suspension system as a backup.

•Get professional help.

To prepare these speakers for suspension:

1.Remove the flathead screws from the top of the speaker.

Note: The 3/8" flathead screws use a 7/32" hex wrench. Take care not to remove both screws from each corner, as the internal bracket will fall inside the loudspeaker.

2.Apply a drop of thread locking adhesive to the end of the threads of the eyebolts.

Note: Please use the supplied eyebolts found in the carrying handle of the speaker. If you use any part other than that supplied, be sure it is Load Rated and know that it will be de-rated if not suspended so that the pull direction is in-line.

3.Install the eyebolts into the holes on top of the speaker and finger-tighten.

4.Securely tighten the eyebolts. Hand tighten +1/2 turn.

5.Inspect the other six (6) flathead screws, making sure they are tightened down.
