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.
KEEP THIS OWNER’S MANUAL IN A SAFE PLACE
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. They 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 SW118IVN/SW215IVN 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!
For the five models, S112IVN, S115IVN, SM10IVN,
SM12IVN, and SM15IVN, use the TS-30, TS-40, TS-80,
or TS-90 speaker stand by Ultimate Support System, Inc.
sold separately.
When using speaker stands, observe the following precautions to prevent the speaker stands from falling over or the
speaker system being dropped.
• Use the speaker stands with their legs fully opened.
• Do not place more than one speaker on the same speaker
stand.
• Tighten fastening screws securely.
• Remove the speakers from the stands before moving the
stands or adjusting their height.
• Implement measures to prevent the speaker stands from
falling over.
• Use the TS-30, TS-40 at no higher than 130 cm for the
S112IVN, SM10IVN, SM12IVN and at no higher than
120 cm for the S115IVN and SM15IVN.
• Use the TS-80 and TS-90 at no higher than 140 cm for
all speaker models.
• The top tube of the TS-30 and TS-40 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 SW118IVN, SW215IVN subwoofer has a metal socket
to allow mounting of a satellite speaker. Do not use a pole
longer than 56". Use a pole with an outer diameter of 1-3/
8".
SPEAKER HANDLES
The handles on your speakers are for transportation. They
are not designed for suspension or hanging.

Daisy-Chaining Speakers
Since the speaker systems in this series are equipped with two input terminals that are internally connected in parallel, it is
possible “daisy-chain” speakers by connecting the output from the power amplifier to one Neutrik connector, and a second
speaker system to the other.
We do not recommend connecting more than two 8 speakers in parallel. Two parallel-connected 8 speakers have a total
impedance of 4 , which is the minimum that should be connected to one amplifier output channel. The S112IVN, S115IVN,
SM10IVN, SM12IVN, SM15IVN and SW118IVN are 8 speakers, and two of these can safely be paralleled on one output. The
S215IVN and SW215IVN, however, have an impedance of 4 and should not be parallel-connected with another S215IVN /
SW215IVN or any other model.
Neutrik NL4FC Plug Wiring
If you will be using the Neutrik connectors for speaker input, wire the plugs as shown below. Be sure to use proper speaker
cable—NOT shielded instrument or line cable—for all speaker connections.

Caution: Use only unshielded speaker cable with stranded conductors to connect speakers to the speaker terminals on a power
amplifier. The use of audio cable not rated as sufficient for the amplifier’s maximum output level can create a potential fire
hazard.

• Do not connect the PN90 between the power amplifiers and the SW118IVN, SW215IVN subwoofers, as doing so will damage
the equipment.
• Although the PN90 has a standard load impedance of 15 k , it can be used with loads between 7.5 and 30 k , allowing use
with most power amplifiers.
• Since the LOW signal polarity is inverted at the crossover point between the LOW and HIGH signals, be sure to reverse the
polarity when connecting the SW118IVN, SW215IVN input connectors to the power amplifier output connectors.
This polarity correction must not be made by reversing the polarity of the connections between the PN90 and the power
amplifiers, as doing so will damage the equipment. Please reverse the polarity between the power amplifiers and the
SW118IVNs, SW215IVNs.
• The PN90 uses unbalanced connectors. Use shielded audio cable with high-quality phone plugs to connect the PN90.
The balance between the LOW and HIGH signal levels may be adjusted using the power amplifier volume controls. A good
starting point is generally achieved for typical sound sources by raising the LOW signal level about 8 dB higher than that of the
HIGH signal.
