Supplied accessories

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

Subwoofer cable (5 m)

Positioning the subwoofer

（subwoofer，front speaker)

It is recommended to place the subwoofer on the outside of either the right or the left front speaker. (See fig. A) 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. A

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.

Caution: Plug the power cables for the subwoofer and other audio/video components into an AC outlet only after you complete all other connections.

Basic connection example

Connect the subwoofer cable to the output jack of your AV amplifier, receiver or TV and to the INPUT jack of the subwoofer.

Amplifier (The rear panel of various amplifiers may differ in appearance.)

Flat TV (The rear panel of various Flat TV may differ in appearance.)

Connecting components and the subwoofer to AC power

After you complete a subwoofer connection, plug the amplifier, TV or other audio/video component, and the subwoofer into an AC outlet of appropriate voltage.

Pre-adjusting the subwoofer volume

Before you use the subwoofer, first adjust the volume balance between the subwoofer and the front speakers by following the procedure below.

1. Set the VOLUME control to minimum (0).
2. Turn on the power to all other components.
3. Press the POWER switch to the ON position. The power indicator on the rear panel lights up green.
4. Play a source that contains low-frequency sounds. Adjust the amplifier's volume control to the desired listening level.
5. Increase the volume gradually to adjust the volume balance between the subwoofer and the front speakers. To enjoy natural bass sound, keep the subwoofer volume at a level where it is barely distinguishable from other speakers.
6. Adjust the volume of the entire sound system using the amplifier's volume control.

Note: It is recommended to set the VOLUME control about in the middle position when using in a multi channel home theater system.

Advanced Yamaha Active Servo Technology II

In 1998, 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.
