CAUTION: Read this before operating your unit. ● ● ● To assure the finest performance, please read this manual carefully. Keep it in a safe place for future reference. Install the speakers in a cool, dry, clean place – away from windows, heat sources, sources of excessive vibration, dust, moisture and cold. Avoid sources of humming (transformers, motors). To prevent fire or electrical shock, do not expose the speakers to rain or water. To prevent the enclosure from warping or discoloring, do not place the speakers where they will be exposed to direct sunlight or excessive humidity. ● 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 performance. For SW-P201 only ● ● ● ● Placing the speakers on the same shelf or rack as the turntable can result in feedback. ● Any time you note distortion, reduce the volume control on your amplifier to a lower setting. Never allow your amplifier to be driven into “clipping”. Otherwise the speakers may be damaged. ● When using an amplifier with a rated output power higher than the nominal input power of the speakers, care should be taken never to exceed the speakers’ maximum input. As these speakers contain strong magnets (though all of them are magnetically shielded types), avoid placing watches, magnetic tapes, etc. near them. Also, placing the speakers near a TV set may impair picture color. If this happens, move the speakers away from the TV set. Do not attempt to clean the speakers with chemical solvents as this might damage the finish. Use a clean, dry cloth. Secure placement or installation is the owner’s responsibility. YAMAHA shall not be liable for any accident caused by improper placement or installation of speakers. For U.K. customers If the socket outlets in the home are not suitable for the plug supplied with this appliance, it should be cut off and an appropriate 3 pin plug fitted. For details, refer to the instructions described below. Note: The plug severed from the mains lead must be destroyed, as a plug with bared flexible cord is hazardous if engaged in a live socket outlet. ● ● ● Never open the cabinet. If something drops into the set, contact your dealer. Do not use force on switches, controls or connection wires. When moving the unit, first disconnect the power plug and the wires connected to other equipments. Never pull the wires themselves. Be sure to read the “TROUBLESHOOTING” section regarding common operating errors before concluding that the unit is faulty. When not planning to use this unit for a long period (ie., vacation, etc.), disconnect the AC power plug from the wall outlet. To prevent lightning damage, disconnect the AC power plug when there is an electric storm. Since this unit has a built-in power amplifier, heat will radiate from the rear panel. Place the unit apart from the walls, allowing enough space above, behind and on the both sides of the unit to prevent fire or damage. Furthermore, do not position with the rear panel facing down on the floor or other surfaces. <For U.K. and Europe models only> Be sure to allow a space of at least 20 cm above, behind and on both sides of the unit. Super-bass frequencies reproduced by this unit may cause a turntable to generate a howling sound. In such a case, move this unit away from the turntable. If you hear distorted noise (i.e., unnatural, intermittent “rapping” or “hammering” sounds) coming from this unit, reduce the volume level. Extremely loud playing of a movie soundtrack’s low frequency, bass-heavy sounds or similarly loud popular music passages can damage this speaker system. VOLTAGE SELECTOR (General model only) The VOLTAGE SELECTOR on the rear panel of this unit must be set for your local main voltage BEFORE plugging into the AC main supply. Voltages are 110-120/220-240 V AC, 50/60 Hz. VOLTAGE SELECTOR 220V-240V 110V-120V SPECIAL INSTRUCTIONS FOR U.K. MODEL IMPORTANT: THE WIRES IN MAINS LEAD ARE COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE: Blue: NEUTRAL Brown: LIVE As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured BLACK. The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED. Making sure that neither core is connected to the earth terminal of the three pin plug. Standby mode If the POWER switch is set to the ON position and the AUTO STANDBY switch is set to the HIGH or LOW position, this unit turns into the standby mode when no signal is inputted to this unit. In this state, this unit is designed to consume a very small quantity of power. WARNING TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE. E-1  COMPONENTS OF THE PACKAGE The speaker package “NS-P210” is designed for use in a multi-channel audio system such as a home theater system.

The positioning of the speakers is important because it controls the whole sound quality of this system. Place the speakers depending on your listening position by following the instructions below. Speaker configuration Placing speakers This speaker package employs a 6 speaker configuration: 2 main speakers, 2 rear speakers, a center speaker and a subwoofer. The main speakers are used for main source sound. The rear speakers are used for surround sounds, and the center speaker is for center sounds (dialog etc.). The subwoofer is for reinforcing low frequencies on your audio system. Note In this speaker package, the same speakers (NX-210P) are used for the main and rear speakers. Main speakers: On both sides of and at approximately the same height as the TV set. Rear speakers: Behind your listening position, facing slightly inward. About 1.8 m (approx. 6 feet) from the floor. Center speaker: Precisely between the main speakers. Subwoofer: The position of the subwoofer is not so critical because low bass tones are not highly directional. Refer to “Placing the subwoofer” below for a recommended positioning of the subwoofer. Main L Center Main R Subwoofer Main R English SETTING UP THE SPEAKERS Subwoofer Center Main L TV-set Rear R Rear L Rear R Rear L m Placing the subwoofer Å ( ı : Subwoofer, : Main speaker) It is recommended to place the subwoofer on the outside of either the right or the left main speaker. (See fig. Å .) The placement shown in fig. ı is also possible, however, if the subwoofer system is placed directly facing the wall, the bass effect may die because the sound from it and the sound reflected by the wall may cancel out each other. To prevent this from happening, face the subwoofer system at an angle as shown in fig. Å. Note There may be a case that you cannot obtain enough superbass sounds from the subwoofer when listening in the center of the room. This is because “standing waves” have been developed between two parallel walls and they cancel the bass sounds. In such a case, face the subwoofer obliquely to the wall. It also may be necessary to break up the parallel surfaces by placing bookshelves etc. along the walls. E-3  m Mounting the main and center speakers Place the main speakers on a rack or on a shelf. Place the center speaker on top of the TV, on a shelf or inside the TV rack so that it is stable. To obtain more stability and usefulness, we recommend that you mount these speakers on the provided mounting brackets (type A). 1 Mounting bracket (type A) Screw (type A) To mount the speakers on the mounting brackets (type A) 1 Attach the bracket to the bottom of the speaker by using the provided screw (type A). 2 Turn and/or slide the speaker on the bracket according to your preference, and then tighten the screw. Note Though this speaker is a magnetically shielded type, there may be some influence on a TV picture depending on the type of TV or the placement of the speaker. In such a case, place the speaker apart from TV so that there is no influence on TV picture. 2 If you want to mount a speaker on a commercially available speaker stand (for the main/center/rear speakers) Mounting bracket (type C) Screw (type A) 60 mm E-4 The provided mounting bracket (type C) with 1 pair of screw holes (at an interval of 60 mm) can be used to mount the speaker on a speaker stand. * Those screw holes can be used with M4 screws only. 1 Attach the bracket to the bottom of the speaker by using the provided screw (type A) so that the convex part of the bracket fits in the grooved part on the bottom of the speaker as shown on the left. 2 Mount the speaker on the speaker stand by using the screw holes on the bracket. Note The mounting bracket (type C) is provided for each of 5 speakers.  English m Mounting the rear speakers Mount the rear speakers on a shelf, rack or directly on the floor, or hang them on the wall. 1 Mounting bracket (type B) To mount the rear speakers on a wall by using the provided mounting brackets (type B) Note It is recommended that you connect the speaker cords to the speaker’s terminals before attaching the bracket to the speaker. Screw (type B) 2 1 Attach the bracket to the bottom of the speaker by using the provided screw (type B). 2 Turn and/or slide the speaker on the bracket according to your preference, and then, tighten the screw. 3 Fasten screws into a firm wall or wall support as shown in the figure, and hang the holes of the mounting bracket on the protruding screws. * Make sure that the screws are securely caught by the narrow parts of the holes. Note If desired, you can hang the speaker directly on the protruding screws on the wall without using the bracket. Tapping screw (Available at the hardware store) 3 65 mm Mounting bracket (type B) Wall/ wall support Min. 12 mm WARNING ● Each speaker weighs 0.7 kg (1 lbs. 9 oz.). Do not mount them on thin plywood or a wall with soft surface material. If mounted, the screws may come out of the flimsy surface and the speakers may fall. This damages the speakers or causes personal injury. ● Do not install the speakers to a wall with nails, adhesives, or any other unstable hardware. Longterm use and vibrations may cause them to fall. ● To avoid accidents resulting from tripping over loose speaker cords, fix them to the wall. ● Select a proper position on the wall to mount the speaker and the bracket so that no one will injure his/ her head or face with the edge of the bracket. E-5  CONNECTIONS General information for connections Caution: Plug in the subwoofer and other audio/video components after all connections are completed. ● Connect the main, center and rear speakers to the speaker output terminals of your amplifier with the provided speaker cords. * The provided speaker cords have labels marked FRONT L, FRONT R, CENTER, REAR L or REAR R. Connect each speaker cord to the corresponding speaker by following the figure below. * Connect each speaker making sure not to reverse the polarity (+, –). If the speaker is connected with reversed polarity, the sound will be unnatural and lack bass. * For the main and rear speakers only, connect one speaker to the left (marked L) terminals of your amplifier, and another speaker to the right (marked R) terminals. ● The subwoofer can be connected to either the line output (pin jack) terminals or the speaker output terminals of the amplifier.

VOLTAGE SELECTOR switch (General model only) If the preset setting of the switch is incorrect, set the switch to the proper voltage range (220V-240V or 110V-120V) of your area. Consult your dealer if you are unsure of the correct setting. WARNING Be sure to unplug the subwoofer before setting the VOLTAGE SELECTOR switch correctly.  English Automatic power-switching function When you play a source, the power of the subwoofer turns on automatically by sensing audio signals input to the subwoofer. On the other hand, the subwoofer automatically switches to the standby mode if the source being played is stopped or the input signal is cut off for a few minutes. This function operates by sensing a certain level of low frequency input signal. Its sensitivity is high in the HIGH position and low in the LOW position of the AUTO STANDBY switch. Set this switch to the position you prefer. In the HIGH position, the power will turn on even with a low level of input signal. But please be aware that the subwoofer may not switch to the standby mode when there is an extremely low input signal. * The power might turn on unexpectedly by sensing noise from other appliances. If that occurs, set the AUTO STANDBY switch to the OFF or LOW position. * The level of low frequency input signal differs with each source and among different parts within the same source. This means that the function may not operate properly on some sources. This function is available only when the power of the subwoofer is on (by setting the POWER switch (1) to “ON”). m Adjusting the subwoofer before use Before using the subwoofer, adjust the subwoofer to obtain the optimum volume balance between the subwoofer and the main speakers by following the procedures described below. Rear panel POWER POWER 2 ON ON OFF OFF VOLUME 1, 4 VOLUME STANDBY-RED ON-GREEN 0 I0 STANDBY-RED ON-GREEN 0 I0 AUTO STANDBY AUTO STANDBY HIGH LOW OFF INPUT2 /MONO HIGH LOW OFF INPUT1 FROM AMPLIFIER OUTPUT TO SPEAKERS 1 2 Set the VOLUME control to minimum (0). 3 Play a source and adjust the amplifier’s volume control to the desired listening level. 4 Increase the volume gradually to adjust the volume balance between the subwoofer and the main speakers. Turn on the power supply to all the components. Note: It is recommended to set the VOLUME control to the middle position when using all the speakers of this package in a 5.1- Once the volume balance between the subwoofer and the main speakers is adjusted, you can adjust the volume of your whole sound system by using the amplifier’s volume control. However, if you change the main speakers NX-210P to others, you must make this adjustment again. VOLUME channel home theater system. 0 I0 E-11  ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY (for SW-P201) The theory of Yamaha Active Servo Technology has been based upon two major factors, the Helmholtz resonator and negative-impedance drive. Active Servo Processing speakers reproduce the bass frequencies through an “air woofer”, which is a port or opening in the speaker’s cabinet. This opening is used instead of, and performs the functions of, a woofer in a conventionally designed speaker system. Thus, signals of low amplitude within the cabinet can, according to the Helmholtz resonance theory, be outputted from this opening as waves of great amplitude if the size of the opening and the volume of the cabinet are in the correct proportion to satisfy a certain ratio. In order to accomplish this, moreover, the amplitudes within the cabinet must be both precise and of sufficient power because these amplitudes must overcome the “load” presented by the air that exists within the cabinet. Thus it is this problem that is resolved through the employment of a new design in which the amplifier supplies special signals. If the electrical resistance of the voice coil could be reduced to zero, the movement of the speaker unit would become linear with respect to signal voltage. To accomplish this, a special negative-impedance output-drive amplifier for subtracting output impedance of the amplifier is used. By employing negative-impedance drive circuits, the amplifier is able to generate precise, low-amplitude, lowfrequency waves with superior damping characteristics. These waves are then radiated from the cabinet opening as high-amplitude signals. The system can, therefore, by employing the negative-impedance output drive amplifier and a speaker cabinet with the Helmholtz resonator, reproduce an extremely wide range of frequencies with amazing sound quality and less distortion. The features described above, then, are combined to be the fundamental structure of the conventional Yamaha Active Servo Technology. Our new Active Servo Technology — Advanced Yamaha Active Servo Technology — adopted Advanced Negative Impedance Converter (ANIC) circuits, which allows the conventional negative impedance converter to dynamically vary in order to select an optimum value for speaker impedance variation. With this new ANIC circuits, Advanced Yamaha Active Servo Technology can provide more stable performance and improved sound pressure compared with the conventional Yamaha Active Servo Technology, resulting in more natural and dynamic bass reproduction.

If the problem you are experiencing is not listed below or if the instructions given below do not help, disconnect the power cord and contact your authorized YAMAHA dealer or service center. Problem Cause What to Do Power is not supplied even though the POWER switch is set to the ON position. The power plug is not securely connected. Connect it securely. No sound. The VOLUME control is set to 0. Turn the VOLUME control to the right. Speaker cords are not connected securely. Connect them securely. Speaker cords are not connected correctly. Connect them correctly, that is L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. A source sound with few bass frequencies is played. Play a source sound with bass frequencies. It is influenced by standing waves. Reposition the subwoofer or break up the parallel surface by placing bookshelves etc. along the walls. The POWER switch is set to the OFF position. Set the POWER switch to the ON position. The AUTO STANDBY switch is set to the OFF position. Set the AUTO STANDBY switch to the “HIGH” or “LOW” position. The level of input signal is too low. Set the AUTO STANDBY switch to the “HIGH” position. The subwoofer turns into the standby mode unexpectedly. The level of input signal is too low. Set the AUTO STANDBY switch to the “HIGH” position. The subwoofer turns on unexpectedly. There is an influence of noise generated from external appliances etc. Move the subwoofer farther away from such appliances and/or reposition the connected speaker cables. Otherwise, set the AUTO STANDBY switch to the “OFF” position. Sound level is too low. The subwoofer will not turn on automatically.
