Install the speakers in a cool, dry, clean place – away from windows, sources of heat, sources of excessive vibration, dust, moisture or cold. Avoid sources of electrical humming (e.g., transformers and motors). To prevent fire or electric shock, do not expose the speakers to rain or water. 3 To prevent the enclosure from warping or discoloring, do not expose the speakers to direct sunlight or excessive humidity. 4 Avoid installing the speakers where foreign objects may fall onto them and/or where they may be exposed to liquid dripping or splashing. 5 Do not place the following objects on top of the speakers: – Other components, as they might damage or discolor the surface of the speakers. – Burning objects (e.g., candles), as they might cause fire, damage to the speakers or personal injury. – Containers of liquid, as they might spill and cause electric shock to the user or damage to the speakers. 6 Do not place the speakers where they are liable to be knocked over or struck by falling objects. Stable placement will also ensure better sound. 7 Placing the speakers on the same shelf or rack as the turntable can result in feedback. 8 Secure placement or installation is the owner’s responsibility. YAMAHA is not liable for accidents caused by improper placement or installation of speakers. 9 If you note distortion, reduce the volume control on your amplifier. Do not drive your amplifier to the point of “clipping”. Otherwise, the speakers may be damaged. 10 When using an amplifier with a rated output power higher than the nominal input power of the speakers, care should be taken not to exceed the maximum input of the speakers. with the rear panel facing down on the floor or other surfaces. 4 When using a humidifier, be sure to avoid condensation inside this unit by allowing enough space around the unit and avoiding excess humidification. Condensation might cause fire, damage to the unit, and/or electric shock. 5 Do not cover the rear panel of this unit with a newspaper, tablecloth, curtain, etc. to avoid obstructing heat radiation. If the temperature inside the unit rises, it may cause fire, damage to the unit, or personal injury. 6 Do not plug this unit into a wall outlet until all connections are complete. 7 The voltage to be used must match that specified on the rear panel. Using this unit with a voltage higher than specified is dangerous and may cause fire, damage to the unit, and/or personal injury. YAMAHA is not responsible for damage resulting from use of this unit with a voltage other than specified. 8 Super-bass sound reproduced by this unit may cause a turntable to generate audio feedback. In this case, move the unit away from the turntable. 9 This unit may be damaged if certain sounds are continuously output at high volume level. For example, if 20Hz–50Hz sine waves from a test disc or bass sounds from an electronic instrument, etc. are continuously output, or if a turntable stylus touches the surface of a disc, reduce the volume level to prevent the unit from being damaged. 10 If you hear distorted noise (i.e., unnatural, intermittent “rapping” or “hammering” sounds) from this unit, reduce the volume level. Extremely loud movie soundtrack low frequency, bass-heavy sounds, or similarly loud popular music passages can damage this unit. 11 Vibration generated by super-bass sound may distort images on a TV. In this case, move the unit away from the TV set. 11 Do not clean the speakers with chemical solvents as this might damage the finish. Use a clean, dry cloth. 12 When disconnecting the power cord from the wall outlet, grasp the plug; do not pull the cord. 12 Do not attempt to modify or fix the speakers.

The positioning of the speakers is important because it controls the whole sound quality of your audio system. Place the speakers depending on your listening position by following the instructions below. Placing speakers Front R TV set Front L Subwoofer Center Surround R Surround center (for NS-P446) Surround L Front speakers: On both sides of your TV set. Approximately at the same height as the TV set. Surround speakers: Behind your listening position, facing slightly inward. About 1.8 m (approx. 6 feet) from the floor. Center speaker: Precisely between the front speakers. You can place the center speaker on top of the TV if the top is flat, on the floor under the TV, or inside the TV rack. Be sure to place the speaker in a stable position. Surround center speaker (for NS-P446): Precisely between the surround speakers. Subwoofer: The position of the subwoofer is not so critical because bass sound is not highly directional. Refer to “Placing the subwoofer (SW-P440)” on page 5 for a recommended positioning of the subwoofer. <NS-P440> This speaker package employs a 6 speaker configuration: 2 front speakers, a center speaker, 2 surround speakers and a subwoofer. The front speakers carry most of the music/sound effects. The center speaker emits center sound such as dialog, and the surround speakers provide the surround/ambient effects. The subwoofer adds the low-frequency bass sound. <NS-P446> This speaker package employs a 7 speaker configuration: 2 front speakers, a center speaker, 2 surround speakers, a surround center speaker and a subwoofer. The front speakers carry most of the music/sound effects. The center speaker emits center sound such as dialog, and the surround and surround center speakers provide the surround/ambient effects. The subwoofer adds the lowfrequency bass sound. Note The same speakers (NX-E440) are used for the front and surround speakers and surround center speakers (for NS-P446). English 3  SETTING UP THE SPEAKERS Mounting the speakers on the wall (NX-E440) You can mount the speakers on a wall. To mount the speakers on a wall, use the holes of the brackets attached on the back panels of the speakers. Rear view 2 Hang the speaker by mounting the holes on the protruding screws. Make sure that the screws are securely affixed by the narrow parts of the holes. 40 mm Holes 1 Fasten two screws into a firm wall or wall support at the interval shown below. Tapping screw (Available at the hardware store) Diam. 3.5 to 4 mm Caution 40 mm Min. 20 mm 4 mm Wall/Wall support 4 • Each speaker weighs as follows ........................................................................... 1.4 kg • Do not mount the speakers on thin plywood or a wall composed of a soft surface material. If mounted, the screws may pull out of the flimsy surface and the speakers may fall. This may damage the speakers or cause personal injury. • Do not affix the speakers to a wall using nails, adhesives, or any other unstable hardware. Longterm use and vibrations may cause the speakers to fall. • To avoid accidents resulting from tripping over loose speaker cables, fix the cables to the wall. • Select an appropriate position on the wall to mount the speaker so that no one will injure his/her head or face.  SETTING UP THE SPEAKERS Installing the speakers on wall/ ceiling brackets or speaker stands (NX-E440) Peel off the seal You can also use the screw holes on the rear panel or the bottom of the speakers to install the speakers on commercially available wall/ceiling brackets or speaker stands (if you do not use the attached mounting brackets). Peel off the seal ■ Using commercially available wall/ ceiling brackets A screw with a diameter of 6 mm can be used. (Hole depth: 15 mm) Placing the subwoofer (SW-P440) 60 mm Rear view ■ Using commercially available speaker stands A screw with a diameter of 4 mm can be used. (Hole depth: 9 mm) It is recommended to place the subwoofer on the outside of either the right or the left front speaker (figure A). The placement shown in figure B is also possible, however, if the subwoofer is placed directly facing the wall, the bass sound may lessen because the sound from the subwoofer and the sound reflected by the wall may cancel out each other. To prevent this from happening, face the subwoofer obliquely to the wall. Figure B Figure A YAMAHA Speaker stand SPS-30MMS (example) 60 mm Bottom view * The YAMAHA speaker stand SPS-30MMS may not be available in some areas. Placing the speaker (NX-C440) ( : Subwoofer, : Front speakers) ■ Use the non-skid pads Put the provided non-skid pads at the four corners on the bottom of the subwoofer to prevent the subwoofer from moving by vibrations, etc. When placing the speaker on top of the TV rack, etc., attach the provided fasteners at two points on the bottom of the speaker and on the top of the TV. Notes English • Do not place the center speaker on top of a TV whose area is smaller than the bottom of the speaker. If placed, the speaker may fall and cause injury. • Do not place the center speaker on top of a TV if the top is inclined. • Do not touch the adhesive surface after peeling off the seal as this will waken its adhesive strength. • Thoroughly wipe clean the surface where the fastener is to be applied. Note that adhesive strength is weakened if the surface is dirty, oily or wet and that this may cause the center speaker to fall. 5  CONNECTIONS CONNECTIONS Caution Plug in the subwoofer and other audio/video components after all connections are completed.

However, if you change the speakers or the system configuration, you must make this adjustment again.  USING THE SUBWOOFER (SW-P440) Advanced Yamaha Active Servo Technology II QD-BASS TECHNOLOGY In 1988, Yamaha brought to the speaker systems utilizing YST (Yamaha Active Servo Technology) to give powerful, high quality bass reproduction. This technology uses a direct connection between the amplifier and speaker, allowing accurate signal transmission and precise speaker control. As this technology uses speaker units controlled by the negative impedance drive of the amplifier and resonance generated between the cabinet capacity volume and port, it creates more resonant energy (the “air woofer” concept) than the standard bass reflex method. This allows for bass reproduction from much smaller cabinets than was previously possible. Yamaha’s newly developed Advanced YST II adds many refinements to Yamaha Active Servo Technology, allowing better control of the forces driving the amplifier and speaker. From the amplifier’s point of view, the speaker impedance changes depending on the sound frequency. Yamaha developed a new circuit design combining negative-impedance and constant-current drives, which provides a more stable performance and clear bass reproduction without any murkiness. QD-BASS (Quatre Dispersion Bass) technology uses down-firing drivers with square, pyramid-shaped reflective plates to radiate the sound efficiently in four horizontal directions. The reflective plates (not used in competitors' down-firing subwoofers) negate any effects caused by the floor surface and reduce resonance between sound waves reflected from the floor and the unit. Also, most other systems use circular cones, but by radiating in four directions to avoid the legs of the cabinet, QD-BASS reduces turbulence caused by reflection from the legs. Changing the height of the square pyramid varies the acoustic load, permitting relatively simple high-cut adjustment and improved band pass properties. The QD-BASS system provides extraordinary power and smooth frequency response from an extremely compact unit. It also allows greater freedom of placement, since the sound radiates with equal effectiveness in all directions.
