User manual YAMAHA Q2031B

[. . . ] · If you use a metal socket of the SW115V/SW118V subwoofer to allow mounting of a satellite speaker, use a pole shorter than 90cm with an outer diameter of 35mm. · When transporting or moving the device, always use two or more people. · Do not expose the device to excessive dust or vibrations, or extreme cold or heat (such as in direct sunlight, near a heater) to prevent the possibility of panel disfiguration or damage to the internal components. · Do not place the device in an unstable position where it might accidentally fall over. Connections · Before connecting the device to other devices, turn off the power for all devices. [. . . ] · Use only speaker cables for connecting speakers to the speaker jacks. · Be sure to observe the amplifier's rated load impedance (see page 4), particularly when connecting speakers in parallel. Connecting an impedance load outside the amplifier's rated range can damage the amplifier. Handling caution · Do not use the device for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician. 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. A pair of parallel-connected 8-ohm speakers have a total impedance of 4 ohms. The S112V/S115V/Q2031B/SM12V/ SM15V/SW115V/SW118V are 8-ohm speakers, and two of these can safely be paralleled on one output. The S215V/SW218V, however, has an impedance of 4 ohms and should not be parallel-connected with another S215V/SW218V or any other model. These models can be connected in parallel, however, if you are using a power amplifier that can safely drive load impedances of 2 ohms or lower. 4 Subwoofers and the P-Series Power Amplifiers ENGLISH Adding subwoofers to speaker systems like the one shown in the diagram can provide superior dynamic range and overall sound quality. After inputting the line-level audio from the preamplifier or mixing console into the Yamaha P-series power amplifiers (P7000S/P5000S/P3500S/P2500S), the separate frequency bands are outputted from the amplifiers.
