Thank you for selecting this YAMAHA NS-300/NS-200 speaker system.

PRECAUTIONS

Read these precautions carefully before using your speaker. q 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 speaker may be damaged. q When using an amplifier with a rated output power higher than the nominal input power of the speaker, care should be taken never to exceed the speakers maximum input. q Do not attempt to clean the speaker with chemical solvents as this might damage the finish. To clean, wipe with a dry, soft cloth.
To prevent the enclosure from warping or discoloring, do not place the speaker where it will be exposed to direct sunlight or excessive humidity. Do not place the speaker where it is liable to be knocked over or struck by falling objects. Stable placement will also ensure better sound performance. Secure placement or installation is the owners responsibility. YAMAHA shall not be liable for any accident caused by improper placement or installation of the speaker.
PRECAUTIONS WHEN POSITIONING THE SPEAKERS
The speaker is constructed with the majority of the weight located in its upper portion, and is thus susceptible to falling over if proper care is not taken to insure its stability. If the speaker falls over, it may damage the speaker or be the cause of injury (or even death) to persons and/or damage to personal property. Use the stands included with the speakers to increase stability: q Stands Be sure to use the stands regardless of where the speakers are positioned. Attaching the stands included with the speakers reinforces the base of the speaker not to fall over. Please be cautioned that even though the stands are connected, this does not guarantee that the speakers will not fall over.
For safe and proper use of the speaker: Position the speaker in a location that is solid, level, smooth, and low (with respect to the floor). Do not push or apply pressure to the side of the speaker when moving, or lean objects against the side of the speaker. Do not sit on or set objects on top of the speaker. Vibrations or jolts associated with earthquakes and other phenomena or activities may cause the speaker to fall over. For safety reasons, using commercially available products that increase stability in the speaker is recommended (metal fittings or chains, etc.).

Spike x 4

Washer x 4

Pad x 4
When setting up the speakers on a thick carpet, use the spikes instead of the stand. With 4 points set in place to achieve increased stability and improvements in sound quality.

When positioning the speakers, be sure to use the stand to increase stability. Use the 8 specified holes located on the base of the speaker.
Procedure: Put the 6 mm screw through the inside hole on the stand. Place a washer on the screw on the speaker side of the stand and attach to the speaker at one of the outside holes on the base of the speaker. At this time, attach the stand so that it can still be moved slightly. Put the 4 mm wood screw through the outside hole on the stand, and screw into the inside hole on the base of the speaker. When both screws have been attached, tighten both of the screws so that the stand is firmly in place. Be sure to check that the stand is firmly attached. Attach the pads to the bottom of the end portion of the stand. Attach the other stands in the same manner and confirm that all 4 stands have been firmly attached. Place the speaker in the desired location. Note If force is applied to the side of the speaker, it may fall and damage the speaker or cause personal injury. Please be careful.
Procedure: Set the nut close to the tip of the spike and screw them into the bottom of the speaker at each of the four specified holes. Place the speaker in the desired location in an upright position and adjust the length of the spike to match the depth of the carpet. When adjustment is complete, twist the nut up to the base of the speaker firmly. Notes The tips of the spikes may scratch or otherwise damage the flooring. Please be careful when positioning the speakers. q If force is applied to the side of the speaker, it may fall and damage the speaker or cause personal injury. Please be careful.

s Connections

Connect the screw-type input terminals at the rear of the speakers to the speaker output terminals of your amplifier with the speaker cables. q Connect the (+) terminals on both the amplifier and the speakers using one side of the cable. Connect the () terminals on both components using the other side of the cable. q Connect one speaker to the left (marked L) terminals of your amplifier, and another speaker to the right (marked R) terminals, making sure not to reverse the polarity (+, ). If one speaker is connected with reversed polarity, the sound will be unnatural and lack bass. Procedure: Loosen the terminal knob. Remove approx. 10 mm (3/8) insulation from the speaker cable and insert the bare wire end properly into the terminal hole. Tighten the knob. Test the security of the connection by tugging lightly on the cable at the terminal. Note Do not let the bare speaker wires touch each other as this could damage the speaker and/or the amplifier.
Bi-Wiring Connections This speaker system is capable of bi-wiring connections. To connect the speakers to the output terminals of the amplifier, two pairs of cables for each of woofer and tweeter are used instead of standard connections. This type of connection decreases the modulation distortion caused by electric resistance of the cables and driving current of the speakers. Consequently, purer sound quality can be expected. To utilize bi-wiring connections, remove the short bars from the terminals first, and then connect the woofer and tweeter to the amplifier separately using two pairs of cables. Note For bi-wiring connections, use the same type of cable for both the woofer and tweeter, making sure to match the polarity.

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 it will be exposed to direct sunlight or excessive humidity. Do not place the speakers where it is liable to be knocked over or struck by falling objects. Stable placement will also ensure better sound performance. 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 TV set. Do not attempt to clean the speakers with chemical solvents; this might damage the finish. Use a clean, dry cloth. Secure placement or installation is the owners responsibility. YAMAHA shall not be liable for any accident caused by improper placement or installation of the speakers.

<For SW-P30 only>

Never open the cabinet. If something drops into the set, contact your dealer. Do not use force on switches, controls or connection cords. When moving the unit, first disconnect the power plug and the cords connected to other equipment. Never pull the cords itself. 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 long periods of time (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 electrical storm. Since this unit has a built-in power amplifier, heat will radiate from the rear panel. Therefore, place the unit apart from the walls, allowing enough space above, behind and on the both sides of the unit to prevent fire and damage. Also, do not position with the rear panel facing down on the floor or other surface. <For Europe and Singapore models only> Be sure to allow a space of at least 20 cm above, behind and on the 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 distortion (i.e., unnatural, intermittent rapping or hammering sounds) coming from this unit, reduce the volume level. Extremely loud playing of a movie soundtracks low frequency, bass-heavy sounds or similarly loud popular music passages can damage this speaker system. This unit is not disconnected from the AC power source as long as it is connected to the wall outlet, even if this unit itself is turned off. This state is called the standby mode. In this state, this unit is designed to consume a very small quantity of power.

SUPPLIED ACCESSORIES

After unpacking, check that the following parts are contained. Speaker cords Velcro strips (for NS-C103)

SETTING UP THE SPEAKERS

Before you make connections, place all speakers in their proper positions respectively. The positioning of speakers is important, because it controls the whole sound quality of this system. Position the speakers based on your listening position by following instructions in this section.

Speaker configuration

This system employs a 6 speaker configuration: 2 main speakers, 2 effect speakers, a center speaker and a subwoofer. The main speakers are used for main source sound. The effect speakers are used for effect and surround sounds, and the center speaker is for center sounds (dialog etc.). The subwoofer is for reinforcing low frequencies on your audio system.

Placing speakers

Main speakers:
On both sides of the TV and almost the same height as the TV.
Effect speakers: Behind your listening position, facing
slightly inward. Nearly 1.8 m (approx. 6 feet) up 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 shown below for a recommended positioning of the subwoofer.

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.
It is recommended to place the subwoofer on the outside of either the right or the left main speaker. (See fig. A.) The placement shown in fig. B 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. To prevent this, face the subwoofer system obliquely to the wall as shown in fig. A.
s Mounting the center speaker
Place the center speaker on the TV, on the floor under the TV or in the TV rack so that it is stabilized. When placing the speaker on top of the TV, to prevent the speaker from falling down, put the provided velcro strips at two points on both bottom of the speaker and top of the TV.

8 POWER switch

Set this switch to the ON position to turn on the power of this unit. When the power of this unit is on, the power indicator above the POWER switch lights in green. Set this switch to the OFF position to turn off the power of this unit. Automatic power-switching function When you play a source, the power of this unit turns on automatically by sensing audio signals input to this unit. This unit turns into the standby mode automatically if the source being played is stopped or the input signal is cut off for several minutes. This function will operate 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 whichever position you like. In the HIGH position, the power will turn on even with a low level of input signal, but on the other hand this unit may not turn into the standby mode when there is an input signal even if its level is extremely low. * There may be a case that the power turns on unexpectedly by sensing noise from other appliances. If it occurs, set the AUTO STANDBY switch to the OFF or LOW position. * The level of low frequency input signal differs with each source, and each different part on the same source. So, this function may not operate properly depending on some sources. This function is available only when the power of this unit is on (by setting the POWER switch (8) to ON).

6 AUTO STANDBY (HIGH/LOW/OFF) switch
By setting this switch to the HIGH or LOW position, this units automatic power-switching function operates as described right. If you do not need this function, set to the OFF position. * Make sure to change the setting of this switch only when this unit is in the standby mode.

7 Power indicator

Lights in green when the POWER switch set to the ON position, and goes off when set to the OFF position. * 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 indicator lights in red when no signal is input to this unit.
ADJUSTMENT BEFORE USING THE SUBWOOFER
Before using the subwoofer, make an adjustment on the subwoofer to obtain the optimum volume and tone balance between the subwoofer and the main speakers by following the procedures shown below.
Set the VOLUME control to minimum. Turn on the power supply to all the components. Play any source and adjust the amplifiers volume control to the desired listening level. Increase the volume gradually to adjust the volume balance between this unit and the main speakers. If necessary, you may set the HIGH CUT switch to the HIGH position.
Notes 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 only the amplifiers volume control. However, if you change the main speakers NS-M103 to others, you must make this adjustment again. For adjusting the VOLUME control and the HIGH CUT switch, refer to FREQUENCY CHARACTERISTICS shown below.
Note about setting the HIGH CUT switch This system is designed so that the optimum tone balance between the subwoofer and the main speakers is obtained when this switch is set to the LOW position. However, the tone balance may change depending on the room size, the distance from the subwoofer to the main speakers, and so on. So, if necessary, switch it to the HIGH position.

s FREQUENCY CHARACTERISTICS
Fig. 1 shows the frequency characteristics of the subwoofer with each position (HIGH/LOW) of the HIGH CUT switch. Fig. 2 shows the optimum volume level with the HIGH CUT switch at the LOW position and its frequency characteristics when this subwoofer is combined with NS-M103 (main speakers).

ACTIVE SERVO TECHNOLOGY (for SW-P30)
The theory of Active Servo Technology is based upon two major factors, the Helmholtz resonator and negativeimpedance drive. Active Servo Processing speakers reproduce the bass frequencies through an air woofer, which is a port or opening in the speakers 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 output from this opening as waves of great amplitude if the design is such that 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 design in which the amplifier functions to supply 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, and, 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 low-frequency waves with superior damping characteristics, and these waves are then radiated from the cabinet opening as highamplitude 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 Active Servo Technology.
