Yamaha R118W [3/9] English

ENGLISH

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.

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.

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.

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 fol-

lowed if its output is lost.
