User manual YAMAHA S112V

[. . . ] These precautions include, but are not limited to, the following: Location · If you use a stand, check the stand's specifications and make sure that it is sturdy enough to support the weight of the speaker. You may need to limit the number of people around the placed stand, in order to avoid toppling the device or causing damage to the internal components. · If you use the TS-80 and TS-90 speaker stands manufactured by Ultimate Systems (sold separately) to support the S112V/S115V/SM10V/SM12V/SM15V speaker models, be sure to keep the following cautions. ­ Use the speaker stands with their legs fully opened. [. . . ] 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 6). 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. 3 ENGLISH Poly Switch Connecting the Speakers I Phone Plug Wiring Phone plugs for connection to the phone jack inputs should be wired as shown to the right. Be sure to use proper speaker cable -- NOT shielded instrument or line cable -- for all speaker connections. I Neutrik NL4FC Plug Wiring If you will be using the Neutrik connectors for speaker input, wire the plugs as shown to the right. Be sure to use proper speaker cable -- NOT shielded instrument or line cable -- for all speaker connections. 2­ (NO USE) 1+ : HOT(+) 1­ :COLD (­) Neutrik NL4FC connector 2+ (NO USE) I Full-range Connection Each speaker features four input/parallel connectors--two 1/4" phone jacks and two Neutrik NL4MP connectors. 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/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 I Subwoofers and the PN90 Crossover Network ENGLISH Adding subwoofers to speaker systems like the one shown in the diagram can provide superior dynamic range and overall sound quality. After dividing the line-level audio from the preamplifier or mixing console into separate frequency bands via the PN90 crossover network, the separate frequency bands are sent to separate power amplifiers.
