Precautions
AVOID EXCESSIVE HEAT, HUMIDITY, DUST AND VIBRATION
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.
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 SYSTEM
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.
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.

FOR FUTURE REFERENCE
Poly Switch
All full-range loudspeakers are fitted with a self-resetting 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.
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.
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.
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 car-
rying 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.
