CONTROLS AND THEIR FUNCTIONS .................... 8

ADJUSTING THE SUBWOOFER

• This subwoofer system employs Advanced Yamaha Active Servo Technology II which Yamaha has developed for reproducing higher quality super-bass sound. (Refer to page 11 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.

• The HIGH CUT switch provides you with two positions (HIGH and LOW) to adjust the tone balance between the subwoofer and the front speakers. After unpacking, check that the following parts are contained. Non-skid pads (1 set, 4 pieces) IMPORTANT: THE WIRES IN MAINS LEAD ARE COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE: Blue: NEUTRAL Brown: LIVE As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured BLACK. The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED. Making sure that neither core is connected to the earth terminal of the three pin plug. VOLTAGE SELECTOR (For Asia and General models only) The voltage selector switch on the rear panel of this unit must be set for your local main voltage BEFORE plugging this unit into the AC main supply. Voltages are 110-120/220-240 V AC, 50/60 Hz. CONTENTS

FEATURES SUPPLIED ACCESSORIES2 ( : subwoofer, : front 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 front speaker. (See fig. .) If using two subwoofers, it is recommended to place them on the outside of each front speaker. (See fig. .) The placement shown in fig. is also possible, however, if the subwoofer system is placed directly facing the wall, the bass effect may lessen 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 fig. or . 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

English Choose one of the following two connecting methods that is more suitable for your audio system.

Choose (pages 3-4) when you want to enjoy 5.1 surround system ■ Choose (pages 5-6) when you want to output the low frequency signals Caution: 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 INPUT 2 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 INPUT 2 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 5-6.)

• 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

VOLUME Subwoofer rear panel9 English 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 procedures described below. 1 Set the VOLUME control to minimum (0). 2 Turn on the power of all the other components. 3 Press the POWER switch to the ON position.

• The Power indicator lights up in green. 4 Play a source containing bass signal 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 front speakers is obtained when this HIGH CUT 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 front speakers, and so on. If necessary, switch it to the HIGH position. 6 Rotate the VOLUME control gradually to adjust the volume balance between the subwoofer and the other 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 switch and the VOLUME control again.

• Once the volume balance between the subwoofer and the front 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 front speakers to others, you must make this adjustment again.

• For adjusting the VOLUME control, the HIGH CUT switch, refer to “Frequency characteristics” on page

YST-SW216 Front speaker11 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 for bass reproduction from much smaller cabinets than was previously possible. 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.
