2 EnEnglish• This subwoofer system employs Advanced YamahaActive Servo Technology II, which Yamaha hasdeveloped for the production of higher quality, super-bass sound. This super-bass sound adds a more realistic,theater-in-the-home effect to your stereo system.• This subwoofer can easily be added to your existing audiosystem by connecting to either the speaker terminals or theline output (pin jack) terminals of the amplifier.• For effective use of the subwoofer, the subwoofer’ssuper-bass sound should be matched to the sounds ofyour front speakers. You can create the best soundquality for various listening conditions by using theHIGH CUT control and the PHASE switch.• The Automatic power-switching function saves you thetrouble of pressing the STANDBY/ON button to turn thepower on and off.• The subwoofer can be linked to a Yamaha component forsimultaneous power on/off operation.Use the supplied system control cable to connect thesubwoofer to a Yamaha component that features asystem connector jack. When you turn on or off thepower to the connected component, the subwoofer willalso be turned on or off.• The flared, gently twisting shape diffuses the vortex ofair generated around the edge of the port, creating asmooth flow of air. This reduces extraneous noise notpresent in the original input signal, and provides clear,accurate low frequency reproduction.• The subwoofer can also reproduce a bass sound that isappropriate for the source. (NS-SW300 only)It features a B.A.S.S. switch that enables you to select abass effect that is suitable for the source.After unpacking, checkthat the followingaccessory is contained.FEATURESSUPPLIED ACCESSORYSystem control cable (5 m x 1)Since the low-end frequencies of audio signals feature long wavelengths, they are almost non-directional to human ears.The super-bass range does not create a stereo image. Therefore, a single subwoofer may be enough to produce a high-quality super-bass sound. However, using two subwoofers (similarly to L and R front speakers) can enhance your acousticexperience.Place the subwoofer as shown in fig. , or for the optimum effect. : subwoofer : front speakerUsing one subwooferPlace the subwoofer on the outside of either the left or rightfront speaker.Placing the subwoofer in between the left andright front speakersIf you are placing the subwoofer in between the left andright front speakers, position it slightly at an angle towardthe wall for better effect.Using two subwoofersPlace them on the outside ofeach front speaker.NOTE• This unit features a magnetically shielded design. However, there is still a chance that placing it too close to a CRT-type TV setmight impair picture color. Should this happen, move this unit away from the TV set.• If the speaker volume is very loud, furniture or window glass may resonate and the subwoofer itself may vibrate. In this case,lower the volume level. To limit resonance, use a thick curtain or similar cloth that tends to absorb sound vibrations effectively.Also, changing the subwoofer position may be helpful.PLACEMENTSubwoofer orientationA B CAorBorCNOTEThe placement shown in the figure below is also possible.However, if the subwoofer system is placed directly facing a wall,the bass effect may suffer due to phase cancellation caused bythe interference between the direct and reflected sounds.To prevent this from happening, place thesubwoofer system at an angle.(Figures , , and )A B CThere may be a case that youcannot obtain enough super-basssound from the subwoofer due tostanding waves.
