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

Installation

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.

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.

Operation

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

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 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.

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 R118W/R118WC sub woofer, the Poly Switch protects the woofer and a similar routine should be followed if its output is lost.
