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 electric 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. Avoid installing the speakers where foreign objects may fall onto them and/or where they may be exposed to liquid dripping or splashing. Do not place the following objects on top of the speakers: ● Other components, as they might cause damage and/or discoloration on the surface of the speakers. ● Burning objects (i.e. candles), as they might cause fire, damage to the speakers and/or personal injury. ● Containers with liquid in them, as they might cause electric shock to the user and/or damage to the speakers. 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. Placing the speakers on the same shelf or rack as the turntable can result in feedback. ● ● ● ● ● ● ● ● ● 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. 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. ● Do not attempt to clean the speakers with chemical solvents as this might damage the finish. Use a clean, dry cloth. Do not attempt to modify or fix the speakers. Contact qualified YAMAHA service personnel when any service is needed. The cabinet should never be opened for any reason. Be sure to read the “TROUBLESHOOTING” section regarding common operating errors before concluding that the speakers are faulty. For YST-SW005 ● ● ● ● Do not cover the rear panel of this unit with a newspaper, a tablecloth, a curtain, etc. in order not to obstruct heat radiation. If the temperature inside this unit rises, it may cause fire, damage to this unit and/or personal injury. Do not plug in this unit to a wall outlet until all connections are completed. The voltage to be used must be the same as that specified on the rear panel. Using this unit with a higher voltage than specified is dangerous and may cause fire, damage to this unit, and/or personal injury. YAMAHA will not be held responsible for any damage resulting from use of this unit with a voltage other than specified. To prevent lightning damage, disconnect the AC power plug when there is an electric storm. 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. This unit may be damaged if certain sounds are continuously outputted at high volume level. For example, if 20 Hz–50 Hz sine waves from a test disc, bass sounds from electronic instruments, etc. are continuously outputted, or when the stylus of a turntable touches the surface of a disc, reduce the volume level to prevent this unit from being damaged. 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. Vibration generated by super-bass frequencies may distort images on a TV. In such a case, move this unit away from the TV set. When disconnecting the power cord from the wall outlet, grasp the plug; do not pull the cord. When not planning to use this unit for a long period (i.e. vacation, etc.), disconnect the AC power plug from the wall outlet.

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 English SETTING UP THE SPEAKERS Placing speakers <NS-P230> This speaker package employs a 6 speaker configuration: 2 main speakers, 2 rear speakers, a center speaker and a subwoofer. The main speakers emit main source sound. The rear speakers emit surround sounds, and the center speaker emits center sounds (dialog etc.). The subwoofer emits reinforcing low frequencies on your audio system. <NS-P236> 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. Rear center speaker (for NS-P236): Precisely between the rear 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. This speaker package employs a 7 speaker configuration: 2 main speakers, 2 rear speakers, a center speaker, a rear center speaker and a subwoofer. The main speakers emit main source sound. The rear and rear center speakers emit surround sounds, and the center speaker emits center sounds (dialog etc.). The subwoofer emits reinforcing low frequencies on your audio system.

(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. Use the nonskid pads Put the provided nonskid pads at the four corners on the bottom of the subwoofer to prevent the subwoofer from moving by vibrations etc. 䡵 Placing the center speaker You can place the 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. When placing the speaker on top of the TV, to prevent the speaker from falling, attach the provided fasteners at two points on the bottom of the speaker and on the top of the TV. Screen Notes ● Do not place the 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 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 weaken 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.

Normally, it is set to LOW, however, you may set to HIGH if necessary. Refer to page 12–13. 02.5.8, 10:19 PM E-11  Automatic power-switching function If the source being played is stopped and the input signal is cut off for 7 to 8 minutes, the subwoofer automatically switches to the standby mode. (When the subwoofer switches to the standby mode by the automatic powerswitching function, the power indicator lights up in red.) When you play a source again, the power of the subwoofer turns on automatically by sensing audio signals input to the subwoofer. This function will operate by sensing a certain level of low frequency input signal. Usually set the AUTO STANDBY switch to the LOW position. However, if the power is not switched to ON or STANDBY smoothly, set the switch to the HIGH position. 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 position and use the POWER switch to switch the power between ON and OFF manually. * This function detects the low-frequency components below 200 Hz of the input signals (i.e., the explosion in the action movie, the sound of the bass guitar or the bass drum, etc.). * The minutes required to switch the subwoofer to the standby mode might change by sensing noise from other appliances. This function is available only when the power of the subwoofer is on (by pressing the POWER switch). 䡵 Adjusting the subwoofer before use Before using the subwoofer, adjust the subwoofer to obtain the optimum volume and tone balance between the subwoofer and the main speakers by following the procedures described below.

Turn on the power of all the other components. * The power indicator on the front panel lights up in green. 4 Play a source containing low-frequency components and adjust the amplifier’s volume control to the desired listening level. 5 Set the HIGH CUT switch to the LOW or HIGH position. This subwoofer 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. The tone balance may change, however, depending on the room size, the distance from the subwoofer to the main speakers, and so on. If necessary, switch it to the HIGH position. 6 Increase the volume gradually to adjust the volume balance between the subwoofer and the main speakers. English 1 2 Normally, set the control to the level where you can obtain a little more bass effect than when this unit is not used. If the desired response cannot be obtained, adjust the HIGH CUT switch and the VOLUME control again. ● 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-230P) to others, you must make this adjustment again. ● For adjusting the VOLUME control and the HIGH CUT switch, refer to “Frequency characteristics” below. 䡵 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 HIGH position, and the frequency characteristics when the subwoofer is combined with NX230P. 100 100 HIGH CUT HIGH 90 VOLUME 90 80 70 80 HIGH CUT LOW 70 0 YST-SW005 I0 60 60 HIGH NX-230P LOW 50 50 HIGH CUT 40 20 50 100 200 500Hz 40 20 Fig. 1 50 100 200 500Hz Fig. 2 E-13 NS-P230-236UB-Ea 13 02.5.8, 10:19 PM  ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY (for YST-SW005) 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.
