[. . . ] ­ 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. [. . . ] · Before moving the device, remove all connected cables. · 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. Before turning the power on or off for all devices, set all volume levels to minimum. · Use only speaker cables for connecting speakers to the speaker jacks. Use of other types of cables may result in fire. · 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. · Do not operate the device if the sound is distorting. Prolonged use in this condition could cause overheating and result in fire. Use either a phone jack or a Neutrik connector to receive input from your sound system/power amplifier. One of the spare connectors can be used to parallel-connect an additional speaker (keeping in mind the impedance considerations mentioned below). MIXING CONSOLE L GRAPHIC EQUALIZER L POWER AMPLIFIER L SPEAKER SYSTEMS R R R SPEAKER SYSTEMS Impedance Considerations When connecting speakers in parallel be sure to check the rated load impedance of the power amplifier. Most power amplifiers are capable of safely driving speakers with minimum impedance of 8 ohms or 4 ohms. A pair of parallel-connected 8-ohm speakers have a total impedance of 4 ohms. The S112V/S115V/SM10V/Q2031A/ 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.
