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 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 sounds from the subwoofer when listening

in the center of the room. This is because “standing

waves” have developed between two parallel walls and

cancel the bass sounds.

In such a case, place the subwoofer at an oblique angle

to the wall. It also may be necessary to break up the

parallel surfaces by placing bookshelves, etc. along the

walls.

the desired response can be obtained.

Normally, set the control to a level a little higher than

the front speaker’s rated minimum reproducible

frequency*.

* The front speaker’s rated minimum reproducible

frequency can be looked up in the speakers’ catalog

or owner’s manual.

6 Increase the volume gradually to adjust the volume

balance between the subwoofer and the front speakers.

Normally, set the control to a 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 control and the

VOLUME control again.

7 Set the PHASE switch to the position which gives you

the better bass sound.

Set the switch to the REV (reverse) position. If the

desired response cannot be obtained, set the switch to

the NORM (normal) position.

8 Select “MOVIE” or “MUSIC” according to the played

source.

MOVIE:

When a movie type source is played, the low-

frequency effects are enhanced to allow listeners to

enjoy more powerful sound. (The sound will be richer

and deeper.)

MUSIC:

When an ordinary music source is played, the

excessive low-frequency components are cut off to

make the sound clearer. (The sound will be lighter to

reproduce the melody line more clearly.)

Notes

• Once the volume balance between the subwoofer and

the front speakers is adjusted, you can adjust the

volume of your entire sound system by using the

amplifier’s volume control.

However, if you change the front speakers to others,

you must make this adjustment again.

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.
