Please read the following operating precautions before use. Yamaha will not be held responsible for any damage and/or injury caused by not following the cautions below.

• To assure the finest performance, please read this manual carefully. Keep it in a safe place for future reference.

• Install this unit 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 this unit to rain or water.

• Never open the cabinet. If something drops into the set, contact your dealer.

• 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 a fire and/or electric shock.

• To reduce the risk or fire or electric shock, do not expose this unit to rain or moisture.

• 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 equipment. Never pull the wires themselves.

• When not planning to use this unit for a long period (ie., vacation, etc.), disconnect the AC power plug from the wall outlet.

• Since this unit has a built-in power amplifier, heat will radiate from the rear panel. Place the unit apart from the walls, allowing at least 20 cm of space above, behind and on 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.

• 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 the unit rises, it may cause fire, damage to the unit and/or personal injury.

• Do not place the following objects on this unit: - Glass, china, small metallic etc. If glass etc. falls by vibrations and breaks, it may cause bodily injury. - A burning candle etc. If the candle falls by vibrations, it may cause fire and bodily injury. - A vessel with water in it If the vessel falls by vibrations and water spills, it may cause damage to the speaker, and/or you may get an electric shock.

• Do not place this unit where foreign objects such as water drips might fall. It might cause a fire, damage to this unit, and/or personal injury.

• Never put a hand or a foreign object into the YST port located on the right side of this unit. When moving this unit, do not hold the port as it might cause personal injury and/or damage to this unit.

• Never place a fragile object near the YST port of this unit. If the object falls or drops by the air pressure, it may cause damage to the unit and/or personal injury.

• Never open the cabinet. It might cause an electric shock since this unit uses a high voltage. It might also cause personal injury and/or damage to this unit.

• When using a humidifier, be sure to avoid condensation inside this unit by allowing enough spaces around this unit or avoiding excess humidification. Condensation might cause a fire, damage to this unit, and/or electric shock.

• 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 output 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 output, 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.

• Do not attempt to clean this unit with chemical solvents as this might damage the finish. Use a clean, dry cloth.

• Be sure to read the “TROUBLESHOOTING” section regarding common operating errors before concluding that the unit is faulty.

• Install this unit near the wall outlet and where the AC power plug can be reached easily.

• 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. CAUTION: Read this before operating your unit. This unit features a magnetically shielded design, but there is still a chance that placing it too close to a TV set might impair picture color. Should this happen, move this unit away from the TV set. 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. In this state, this unit is designed to consume a very small quantity of power.1 En English

• This subwoofer system employs Advanced Yamaha Active Servo Technology II, which Yamaha has developed for reproducing higher quality super-bass sound (refer to page 15 for details on Advanced Yamaha Active Servo Technology II). This super-bass sound adds a more realistic, theater-in-the-home effect to your stereo system.

• This subwoofer can be easily added to your existing audio system by connecting to either the speaker terminals or the line output (pin jack) terminals of the amplifier.

• For the effective use of the subwoofer, the subwoofer’s super-bass sound should be matched to the sounds of your main speakers. You can create the best sound quality for various listening conditions by using the HIGH CUT control and the PHASE switch.

• The Automatic power-switching function saves you the trouble of pressing the STANDBY/ON button to turn the power on and off.

• This subwoofer system is equipped with a linear port unique to Yamaha that provides smooth bass response during playback, minimizing extraneous noise not included in the original input signal. After unpacking, check that the following parts are contained. Non-skid pads (1 set: 4 pieces) FEATURES SUPPLIED ACCESSORIES3 En English ( : subwoofer : main speaker) One subwoofer will have a good effect on your audio system, however, the use of two subwoofers is recommended to obtain more effect. If using one subwoofer, it is recommended to place it on the outside of either the right or the left main speaker (see A). If using two subwoofers, it is recommended to place them on the outside of each main speaker (see B). The placement shown in C 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 in A or B. There may be a case that you cannot obtain enough super-bass 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 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. PLACEMENT

VOLUME control Adjusts the volume level. Turn the control clockwise to increase the volume, and counterclockwise to decrease the volume. Note6 En Choose one of the following two connecting methods that is more suitable for your audio system. ■ Choose [1] (pages 6-7) if your amplifier has line output (pin jack) terminal(s) ■ Choose [2] (pages 8-9) if your amplifier has no line output (pin jack) terminal Unplug the subwoofer and other audio/video components before making connections.

• All connections must be correct, that is to say L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. Also, refer to the owner’s manual of your component to be connected to the subwoofer.

• After all connections are completed, plug in the subwoofer and other audio/video components.

• To connect with a Yamaha DSP amplifier (or AV receiver), connect the SUBWOOFER (or LOW PASS etc.) terminal on the rear of the DSP amplifier (or AV receiver) to the /MONO INPUT2 terminal of the subwoofer.

• When connecting the subwoofer to the SPLIT SUBWOOFER terminals on the rear of the DSP amplifier, be sure to connect the /MONO INPUT2 terminal to the “L” side and the INPUT2 terminal to the “R” side of the SPLIT SUBWOOFER terminals.

• Some amplifiers have line output terminals labeled PRE OUT. When you connect the subwoofer to the PRE OUT terminals of the amplifier, make sure that the amplifier has at least two sets of PRE OUT terminals. If the amplifier has only one set of PRE OUT terminals, do not connect the subwoofer to the PRE OUT terminals. Instead, connect the subwoofer to the speaker output terminals of the amplifier (refer to pages 8-9).

• When connecting to a monaural line output terminal of the amplifier, connect the /MONO INPUT2 terminal.

• When connecting to line output terminals of the amplifier, other speakers should not be connected to the OUTPUT terminals on the rear panel of the subwoofer. If connected, they will not produce sound. CONNECTIONS Caution Notes [1] Connecting to line output (pin jack) terminals of the amplifier

OFF OFF HIGH NORM REV PHASE To AC outlet (U.S.A. model) WARNING VOLTAGE SELECTOR12 En 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. 1 Set the VOLUME control to minimum (0). 2 Turn on the power of all the other components. 3 Make sure that the POWER switch on the rear panel is set to the ON position, then press the STANDBY/ON switch on the front panel to turn on the subwoofer.

• The status indicator lights up in green. 4 Play a source containing low-frequency signals and adjust the amplifier’s volume control to the desired listening level. 5 Adjust the HIGH CUT control to the position where the desired response can be obtained. Normally, set the control to the level a little higher than the main speaker’s rated minimum reproducible frequency*.

• The main speaker’s rated minimum reproducible frequency can be looked up in the speakers’ catalog or owner’s manual. 6 Increase the volume gradually to adjust the volume balance between the subwoofer and the main speakers. Normally, set the control to the level where you can obtain a little more bass effect than when the subwoofer is not used. If the desired response cannot be obtained, adjust the HIGH CUT control and the VOLUME control again. 7 Set the PHASE switch to the position which gives you the better bass sound. Normally, set the switch to the REV (reverse) position. If the desired response cannot be obtained, set the switch to the NORM (normal) position.

• 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 to others, you must make this adjustment again.

• For adjusting the VOLUME control, the HIGH CUT control and the PHASE switch, refer to “FREQUENCY CHARACTERISTICS” on page 14.

YST-RSW300Main speakerFrequency response graph*15 En English In 1988, Yamaha brought to the marketplace speaker systems utilizing YST (Yamaha Active Servo Technology) to give powerful, high quality bass reproduction. This technique 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 speaker cabinet volume and port, it creates more resonant energy ( the “air woofer” concept) than the standard bass reflex method. This allows bass reproduction from much smaller cabinets than before. 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.
