Precautions
WARNING
In case an abnormality occurs during operation
• If you notice any abnormality, such as smoke, odor, or noise, turn the power amp off immediately. Remove the power cord from the AC outlet. Consult your dealer for repair. Using the unit in this condition is a fire and electrical shock hazard.
CAUTION
ENGLISH
Installation Operation
• 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 vibra-
tion.
- Non-level or unstable surfaces.
• To prevent short circuits or breakage of cables, always dis­connect cables prior to moving system equipment.
• 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.
• This unit is heavy. Use two or more people to carry it.
• 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.
• 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.
• Do not output distorted sounds for long periods of time, as this will cause the speaker to heat up, leading to a fire hazard.

To protect your speakers
Poly Switch
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 7). 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.
This product, when used in combination
with amplification and/or additional
loudspeakers, may be capable of produc-
ing sound levels that could cause perma-
nent hearing loss.
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 R118W/R118WC sub woofer, the Poly Switch
protects the woofer and a similar routine should be fol-
lowed if its output is lost.
ENGLISH
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.

Connection Examples
■ Full-range Connection
Each speaker features three input/parallel connectors – two 1/4" phone jacks and one Neutrik NL4MP connector. Use either a phone jack or the Neutrik connector to receive input from your sound system/power amplifier. One of the spare connectors can be used to parallel-connect an additional speaker (keeping in mind the impedance considerations mentioned below).

Impedance Considerations
We do not recommend connecting more than two 8-ohm speakers in parallel. Two parallel-connected 8-ohm speakers have a total impedance of 4 ohms, which is the minimum that should be connected to one amplifier output channel. The R112/R112C, R115/R115C, R12M/R12MC, R15M/R15MC and R118W/R118WC are 8-ohm speakers, and two of these can safely be paralleled on one output. The R215/R215C, however, has an impedance of 4 ohms and should not be parallel-connected with another R215/ R215C or any other model.

■ Using a Channel Divider and Subwoofers
Using a channel divider in a multi-way system like the one shown in the diagram can provide superior dynamic range and overall sound quality. The channel divider divides the line-level audio from the preamplifier or mixing console into separate frequency bands that are then sent to separate power amplifiers. The power amplifiers drive speaker systems selected for optimum performance in the corresponding frequency ranges.

■ Phone Plug Wiring
Phone plugs for connection to the phone jack inputs should be wired as shown to the right. Be sure to use proper speaker cable – NOT shielded instrument or line cable – for all speaker connections.
