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.
FEATURES • 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.
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 main speaker (see A). If using two subwoofers, it is recommended to place them on the outside of each main speaker (see B).

CONNECTIONS [2] Connecting to speaker output terminals of the amplifier Select this method if your amplifier has no line output (pin jack) terminal. For details about the connection method of the INPUT1/OUTPUT terminals, see the “Connecting to the INPUT1/OUTPUT terminals of the subwoofer” on page 10.
CONNECTIONS 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 main 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 up the excess part of the cables. If the connections are faulty, no sound will be heard from the subwoofer or the speakers, or both of them. Make sure that the + and – polarity markings of the speaker cables are observed and set correctly. If these cables are reversed, the sound will be unnatural and lack bass.
CONNECTIONS After all connections are completed, plug in the subwoofer and other audio/video components to the AC outlet. OUTPUT TO SPEAKERS INPUT 2 ■ VOLTAGE SELECTOR switch (For Asia and General models only) This unit has a voltage selector switch on the rear panel. If the preset setting of the switch is incorrect, set the switch to the proper voltage range (110/120/ 220/230-240 V) of your area. Consult your dealer if you are unsure of the correct setting.

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.
