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.
