User manual YAMAHA S115IIIA

[. . . ] ­ Place only one speaker on each speaker stand. ­ Tighten fastening screws securely. ­ Remove the speakers from the stands before moving the stands or adjusting their height. ­ Add weight such as sand bags around the stand legs to prevent them from falling over. [. . . ] If you experience any hearing loss or ringing in the ears, consult a physician. · Do not operate the device if the sound is distorting. Prolonged use in this condition could cause overheating and result in fire. · Always turn AC power to the power amplifier on last in any audio system to avoid speaker damage. When turning power off, the power amplifier should be turned off first for the same reason. 2 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. 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. They should allow the poly switch to reset. Reapply 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 SW115V/SW118V/SW218V sub woofer, the Poly Switch protects the woofer and a similar routine should be followed if its output is lost. The high voltage levels produced can damage the PN90. · Use the PN90 with a load impedance of between 7. 5 and 30k. (Rated load impedance is 15k) · The polarity of the LOW signal is inverted at the crossover point between the LOW and HIGH signals. Compensate for this by reversing the polarity when connecting the power amplifier output jacks to a subwoofer. Note that you must reverse the polarity between the power amplifier and subwoofers rather than between the PN90 and power amplifier to prevent damage to the connected device. · The PN90's connectors are unbalanced phone jacks. Use shielded audio cable with phone plugs to connect to the PN90. · Adjust the level of the LOW and HIGH signals using the power amplifier volume controls. 5 Specifications Model Enclosure Speaker Unit LF HF SM10V 10" cone 1" V.
