• VOLTAGE SELECTOR (Asia and General models only) The voltage selector switch on the rear panel of this unit must be set to your local main voltage BEFORE plugging this unit into the AC main supply. Voltages are 110/120/220/230-240 V AC, 50/60 Hz. 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 by STANDBY/ON button. In this state, this unit is designed to consume a very small quantity of power.
FEATURES • This subwoofer system employs Advanced Yamaha Active Servo Technology II, which Yamaha has developed for the production of higher quality, superbass sound. (Refer to page 14 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.
PLACEMENT One subwoofer will have a good effect on your audio system, however, the use of two subwoofers is recommended to obtain more effect. A If using one subwoofer, it is recommended to place it on the outside of either the right or the left front speaker. (See fig. A .) If using two subwoofers, it is recommended to place them on the outside of each front speaker. (See fig. B .) The placement shown in fig.
CONTROLS AND THEIR FUNCTIONS Top panel Front panel Rear panel (General model) B.A.S.S. (Bass Action Selector System) button When this button is pressed in to the MUSIC position, the bass sound in audio software is well reproduced. By pressing the button again so that it pops out at the MOVIE position, the bass sound in video software is well reproduced. HIGH CUT control Adjusts the high frequency cut off point.
CONTROLS AND THEIR FUNCTIONS POWER switch Set this switch to the ON position to use the subwoofer. In this state, you can turn on the subwoofer or turn the subwoofer into the standby mode by pressing the STANDBY/ON button. Set this switch to the OFF position to completely cut off the subwoofer’s power supply from the AC outlet. OUTPUT (TO SPEAKERS) terminals Can be used for connecting to the main speakers. Signals from the INPUT1 terminals are sent to these terminals. (Refer to “CONNECTIONS” for details.
CONNECTIONS Choose one of the following two connecting methods most suitable for your audio system. ■ Choose 1 ■ Choose 2 (pages 6-7) if your amplifier has line output (pin jack) terminal(s) (pages 8-9) if your amplifier has no line output (pin jack) terminal(s) Caution: Unplug the subwoofer and other audio/video components before making connections. Notes • All connections must be correct, that is to say L (left) to L, R (right) to R, “+” to “+” and “–” to “–”.
CONNECTIONS ■ Using two subwoofers Mono pin cable (not included) Subwoofer Mono pin cable (not included) Subwoofer Amplifier To AC outlet ■ Connecting To AC outlet to the LFE (INPUT3) terminal(s) If your amplifier can cut off high frequencies from the signals for sending to the subwoofer, connect the amplifier to the subwoofer's LFE (INPUT3) terminal(s).This will bring you higher sound quality because the signal routing in the subwoofer is shortened by passing the built-in HIGH CUT circuit.
CONNECTIONS 2 Connecting to speaker output terminals of the amplifier Select this method if your amplifier has no line output (pin jack) terminal(s). If your amplifier has two sets of front speaker output terminals and both terminals can output sound signals simultaneously. • Connect one set of front speaker output terminals of the amplifier to the INPUT1 terminals of the subwoofer, and connect the other set of front speaker output terminals of the amplifier to the front speakers.
CONNECTIONS If your amplifier has only one set of front speaker output terminals. Connect the speaker output terminals of the amplifier to the INPUT1 terminals of the subwoofer, and connect the OUTPUT terminals of the subwoofer to the front speakers.
CONNECTIONS Connecting to the INPUT1/OUTPUT terminals of the subwoofer For connection, keep the speaker cables as short as possible. Do not bundle or roll the excess cabling. If the connections are faulty, no sound will be heard from the subwoofer or the speakers, or both. Make sure that the + and – polarity markings of the speaker cables are observed and connected correctly. If these cables are reversed, the sound will be unnatural and lack bass. U.S.A.
AUTOMATIC POWER-SWITCHING FUNCTION This function automatically switches the unit between standby and power-on mode. The subwoofer automatically places itself in standby mode if it does not receive an input signal for 7 or 8 minutes. (The power indicator lights red.) When the subwoofer detects a bass signal input of below 200 Hz, it automatically places itself in power-on mode. (The power indicator lights green.
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 front speakers by following the procedure described below. 1 2 3 Set the VOLUME control to minimum (0). Turn on the power of all the other components. Make sure that the POWER switch is set to the ON position, then press the STANDBY/ON button to turn on the subwoofer. * The Power indicator lights up in green.

ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY II 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. 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.
