FEATURES

• This subwoofer employs Advanced Yamaha Active Servo Technology II, which Yamaha has developed for the production of 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 audio system.
• Equipped with the smooth super-bass reproducing Twisted Flare Port.

The flared, gently twisting shape diffuses the vortex of air generated around the edge of the port, creating a smooth flow of air. This reduces extraneous noise not present in the original input signal, and provides clear, accurate low frequency reproduction.

CONTROLS AND THEIR FUNCTIONS

Rear

①Twisted Flare Port

Outputs super-bass sound.

②VOLUME control

Adjusts the volume level. Turn the control clockwise to increase the volume, and counterclockwise to decrease the volume.

③Power indicator

Lights up Green when the POWER switch is turned ON; turns off when the POWER switch is turned OFF.

④INPUT (FROM AMPLIFIER) terminal

Used to connect the subwoofer with the subwoofer terminal of the amplifier.

(Refer to "CONNECTIONS" for details.)

⑤POWER switch

Press this switch to the ON position to turn on the power to the subwoofer. Press this switch again to set it to the OFF position to turn off the power of the subwoofer.

⑥VOLTAGE SELECTOR switch

(Asia and General models only)

If the preset setting of the switch is incorrect, set the switch to the proper voltage (110-120/220-240V) of your area.

Consult your dealer if you are unsure of the correct setting.

WARNING

Be sure to unplug the subwoofer before setting the VOLTAGE SELECTOR switch correctly.

PLACEMENT

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.

Note

There may be a case that you cannot obtain enough super-bass sound from the subwoofer due to standing waves.

Note

• Placing the subwoofer too close to a CRT-type TV may impair the picture color or cause a buzzing noise. In this case, place the subwoofer and TV at a separated position where these effects do not occur. This is not an issue with LCD and plasma TVs.
• 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.

CONNECTIONS

Note

• Unplug the subwoofer and other audio/video components before making connections, and do not plug them in until all connections are completed.
• Connecting methods and terminal names on your component (such as an amplifier or receiver) may be different from those used in this book. Please refer to the owner's manual that came with your component.
  • After connecting, make sure that cable is connected firmly.

Connecting to such as subwoofer output terminal or line output (pin jack) terminals of the amplifier

Connect to the subwoofer output terminal of the amplifier (or AV receiver) using commercially available audio pin cable.

If the amplifier (or AV receiver) has no subwoofer output terminal, connect to the line output (such as PRE OUT) terminal.

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

Plug in the subwoofer to the AC outlet

After all connections are completed, plug the subwoofer and other audio/video components into AC outlets.

ADJUSTING THE SUBWOOFER BEFORE USE

Before using the subwoofer, adjust the subwoofer to obtain the optimum volume balance between the subwoofer and the front speakers by following the procedure described below.

1 Set the VOLUME control to minimum (0).
2 Turn on the power of all the other components.
3 Make sure that the POWER switch is set to the ON position.
* The Power indicator lights up in green.
4 Play a source containing low-frequency components and 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.

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 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.

TWISTED FLARE PORT

Today's bass reflex speakers use a Helmholtz resonator to improve their bass reproduction.

However when reproducing bass that is in the frequency region of this Helmholtz resonator, air moves violently in and out through the port between the interior and exterior of the speaker, sometimes producing noise due to the turbulent air flow at the end of the port.

The port and the cabinet resonate at a frequency that is determined by their dimensions and shape. On the other hand, turbulence in the air flow at the end of the port contains a broad range of frequency components that are not present in the input signal. This noise occurs because the broad range of frequency components includes components that match the resonant frequencies of the port and cabinet, causing strong resonance.

The Twisted Flare Port developed by Yamaha changes the way in which the port widens toward its end, and also adds a “twist” to suppress airflow turbulence at each end of the port and thus prevent noise from occurring.

This eliminates the “muddy sound” and “wind noise” that until now have been characteristic of bass reflex speakers, allowing bass to be reproduced clearly.

Air turbulence on both ends of the port creates noise

TROUBLESHOOTING

Refer to the chart below if this unit does not function properly.

If the instructions given below do not help, or if the problem you are experiencing is not listed below, turn off the power to the unit, disconnect the power cord and contact an authorized Yamaha dealer or service center.

Problem Cause What to Do
Power is not supplied even though the POWER switch is set to the ON position.	The power plug is not securely connected.	Connect it securely.
No sound. The volume is set to minimum.	Raise the volume up.
	Connections are faulty (or the connections are incomplete).	Connect them securely.
The sound is interrupted.	The volume is too loud.	Since the output is excessive, reduce the volume level.
Sound level is too low. A source sound with little bass frequency content is being played.		Play a source sound with bass frequencies.
		It is influenced by standing waves. Reposition the subwoofer or break up parallel surfaces by placing bookshelves, etc., along the walls.
