• This subwoofer system employs Advanced Yamaha

Active Servo Technology II, which Yamaha has

developed for the production of higher quality, super-

bass sound. (Refer to page 7 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 easily be added to your existing audio

system by connecting to either the speaker terminals or the

line output (pin jack) terminals of the amplifier.

• For effective use of the subwoofer, the subwoofer’s

super-bass sound should be matched to the sounds of

your front speakers. You can create the best sound

quality for various listening conditions by using the

HIGH CUT control and the PHASE switch.

• The Automatic power-switching function saves you the

trouble of pressing the power switch to turn the power on

and off.

• The subwoofer can be linked to a Yamaha component for

simultaneous power on/off operation.

Use the supplied system control cable to connect the

subwoofer to a Yamaha component that features a

system connector jack. When you turn on or off the

power to the connected component, the subwoofer will

also be turned on or off.

• You can select a bass effect suitable for the source by

using the B.A.S.S. switch.

• This subwoofer system is equipped with a linear port

unique to Yamaha that provides smooth bass response

during playback, minimizing extraneous noise not

included in the original input signal.

After unpacking, check that the following accessory is

contained.

SUPPLIED ACCESSORY

System control cable (5 m x 1)

Since the low-end frequencies of audio signals feature long wavelengths, they are almost non-directional to human ears.

The super-bass range does not create a stereo image. Therefore, a single subwoofer may be enough to produce a high-

quality super-bass sound. However, using two subwoofers (similarly to L and R front speakers) can enhance your acoustic

experience.

Notes

• This unit features a magnetically shielded design. However, there is still a chance that placing it too close to a CRT-type TV set

might impair picture color. Should this happen, move this unit away from the TV set.

• If the speaker volume is very loud, furniture or window glass may resonate and the subwoofer itself may vibrate. In this case,

lower the volume level. To limit resonance, use a thick curtain or similar cloth that tends to absorb sound vibrations effectively.

Also, changing the subwoofer position may be helpful.

Place the subwoofer as shown in fig. or for the optimum effect.

: subwoofer : front speaker

Using one subwoofer

Place the subwoofer on the

outside of either the left or right

front speaker.

Using two subwoofers

Place them on the outside of

each front speaker.

The placement shown in fig. is also possible. However,

if the subwoofer system is placed directly facing the wall,

the bass effect may suffer due to cancellation of direct and

reflected sounds. To prevent this from happening, place the

subwoofer system at an angle, as in fig. or .

Note

There may be a case that you

cannot obtain enough super-bass

sound from the subwoofer due to

standing waves.
