• Never open the cabinet. If any foreign objects drop 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 of 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 equipments. 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.

• To prevent lightning damage, disconnect the AC power plug when there is an electric storm.

• Since this unit has a built-in power amplifier, heat will radiate from the rear panel. Place the unit apart from the walls, allowing spaces of at least 10 cm behind and 20 cm above 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.

Introduction

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 5 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.

• The slim design matches the interior of your home.

Positioning the subwoofer

Supplied accessories

Please conﬁrm that the following item is included in the package.

Subwoofer cable (5 m)

It is recommended to place the subwoofer on the outside of either the right or the left 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 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. .

( : subwoofer, : front speaker)

Note: 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.

Advanced Yamaha Active Servo Technology II

English

In 1998, Yamaha brought to the marketplace speaker systems utilizing YST (

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.
