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-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. 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. · In any system using two or more speakers, be sure to match the connection polarities of all speakers to the amplifier(s) ­ e. g. always connect "+" to "+" and "-" to "-". If the polarities are not properly matched the speakers will be driven out of phase and the sound will suffer. · Use only Neutrik NL4FC plugs for connecting Speakon connectors. Yamaha cannot be held responsible for damage caused by improper use or modifications to the device. * Illustrations in this manual are for explanatory purposes only, and may not match the actual appearance of the product during operation. * Company names and product names used in this Owner's Manual are trademarks or registered trademarks of their respective owners. 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 5). 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.
