SUPPLIED ACCESSORY

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. However, using two subwoofers (similarly to L and R front speakers) can enhance your acoustic experience

Subwoofer orientation

Place the subwoofer as shown in fig. A,B,C or for the optimum effect

Using one subwoofer
Place the subwoofer on the outside of either the left or right front speaker

Placing the subwoofer in between the left and right front speakers
If you are placing the subwoofer in between the left and right front speakers, position it slightly at an angle toward the wall for better effect.

Using two subwoofers
Place them on the outside of each front speaker.

• INPUT1 (FROM AMPLIFIER) terminals
  • Used to connect the subwoofer with the speaker terminals of the amplifier.
• AC IN
  • Connects the supplied power cable.
• HIGH CUT control
  • Adjusts the high frequency cut off point. Frequencies higher than the frequency selected by this control are all cut off (and not output).
• POWER switch
  • During normal usage, set this switch to ON. If you plan not to use the subwoofer for a long period of time, set the switch to OFF.

CONNECTIONS

• Choose this method if your amplifier has line output (pin jack) terminal(s).
• Choose this method if your amplifier has no line output (pin jack) terminals.

Connecting to line output (pin jack) terminal(s) of the amplifier

Note: Audio signals input from the /MONO and INPUT 2 terminals on the subwoofer will not be output from the OUTPUT (TO SPEAKERS) terminals.

Connecting one subwoofer Connect the SUBWOOFER (or LOW PASS, etc.) terminal on the rear of the amplifier (or AV receiver) to the /MONO INPUT2 terminal of the subwoofer using a commercially available Mono pin cable (1). Alternatively, When connecting the subwoofer to the SPLIT SUBWOOFER terminals (featuring L and R channels) on the rear panel of the amplifier, use a commercially-available Audio pin cable (2) to connect the /MONO INPUT2 terminal to the “L” side, and the INPUT2 terminal to the “R” side of the SPLIT SUBWOOFER terminals

Connecting two subwoofers

Connecting to the INPUT3 (LFE) terminal

If your amplifier (or receiver) can cut off high frequencies from signals sent to the subwoofer, connect the amplifier to the subwoofer’s INPUT3 (LFE) terminal. This will promote higher sound quality because the signal routing in the subwoofer is shortened by bypassing the builtin HIGH CUT circuit.

Connecting to speaker output terminals of the amplifier

Example: Connecting the subwoofer to an amplifier that features one set of speaker output terminals

Use speaker cables to connect the speaker output terminals of the amplifier to the subwoofer’s INPUT 1 (FROM AMPLIFIER) terminals. Connect the front speakers to the subwoofer’s OUTPUT (TO SPEAKERS) terminals. Although the subwoofer is connected between the front speakers and the amplifier, the sound volume or quality will not be affected.

Connecting to the INPUT1/OUTPUT terminals of the subwoofer

Note

• Make sure that the “+” and “–” polarity markings of the speaker cables are observed and set correctly. If these cables are reversed, the sound will be unnatural and lack bass.
• Do not let the bare speaker wires touch each other, because this could damage the subwoofer or the amplifier.
• If the connections are faulty, no sound will be heard from the subwoofer or the speakers. Do not insert the insulation into the hole. Sound may not be produced.
• To avoid accidents resulting from tripping over loose speaker cables, fix them to the floor.

Before connecting
Remove the insulation at the tip of the speaker cable, then twist the core wires together so that they will not become disarrayed and short-circuited.

How to connect

• Loosen the terminal’s knob, as shown in the figure.
• Insert the bare wire.
• Tighten the knob.
• Test the firmness of the connection by pulling lightly on the cable at the terminal.

Connecting the banana plug

• Tighten the terminal knob.
• Simply insert the banana plug into the terminal.

System connections

If you use the included system control cable to connect a subwoofer to a Yamaha component (that features a system connector jack such as a YSP series component or Yamaha receiver), turning on or off the power to the connected component automatically turns the subwoofer on or off.

Connection example

How the System Connection works

• The POWER switch on the rear panel must be set to ON in advance.
• To modify the settings of the connected components, please refer to the owner’s manual that came with the respective component.
• If the unit is turned off by pressing the STANDBY/ON switch on the front panel during system connection, the indicator (green) gently flashes and notifies you that the connected device is ON. Pressing the STANDBY/ON switch again or turning the power of the connected component on again turns the unit power ON and the indicator (green) is lit.

AUTOMATIC POWER-SWITCHING FUNCTION

This function automatically places the subwoofer in standby mode if the subwoofer does not detect a signal from the amplifier for a certain period of time. The subwoofer automatically turns on as soon as it detects a signal from the amplifier. The Automatic power-switching function works as follows when the AUTO STANDBY (HIGH/LOW/OFF) switch is set to LOW or HIGH. (Normally, set the switch to LOW.)

How the Automatic power-switching function works

• The POWER switch on the rear panel must be set to ON in advance.
• The Automatic power-switching function can be activated when the following conditions are met:
• The unit is powered ON
• The AUTO STANDBY switch is set to LOW or HIGH
• If the STANDBY/ON switch on the front panel is pressed and the unit is turned OFF while the unit is in standby
  mode (the indicator is lit in red), the Automatic power-switching function is canceled. Pressing the STANDBY/ON switch again or turning the power of the component connected via system connection on again turns the unit power ON and the Automatic power-switching function can be activated again.

Setting the AUTO STANDBY switch

LOW: The Automatic power-switching function activates at a certain level of input signal. To enable the function, select this position.
HIGH: If the Automatic power-switching function does not work well when the AUTO STANDBY switch is set to LOW, select this position. If the function still does not work, slightly raise the LFE LEVEL on the amplifier.
OFF: The Automatic power-switching function may unexpectedly activate due to the system environment, for example, if the subwoofer detects noise generated from the peripheral components. In this case, select this position to disable the Automatic power-switching function, and manually turn the unit on or off by using the POWER switch or the STANDBY/ON switch

ADJUSTING THE BALANCE

To achieve natural sound with an effective super-bass component, you must adjust the volume and tone balance between the subwoofer and the front speakers. Follow the procedure described below. If your amplifier or other component connected to the system features subwoofer settings, make the appropriate settings on that component

ADJUSTING THE BALANCE

• Set the VOLUME control to minimum (0).
• Turn on the power to the component(s) connected to the subwoofer. If the component is connected to the subwoofer’s SYSTEM CONNECTOR jack, turn on the power to that component.
• Turn the POWER switch ON or press the STANDBY/ON switch to turn on the unit.
• The indicator lights green.
• Play a source that contains low-frequency components and adjust the output level of the front speakers using the amplifier’s volume control to the desired listening level. (Set all tone controls to flat.)
• Adjust the HIGH CUT control to the position where 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.
• The HIGH CUT control has no effect on signals input to the INPUT 3 LFE terminal. ( page 5)
• 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.
• Set the PHASE switch to the position which yields the more natural (or preferable) phasing.
• Set the B.A.S.S. switch to “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 a 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 carry less bass and reproduce the melody line more clearly.)

Subwoofer frequency characteristics

The figures below show the optimum adjustment of each control and the frequency characteristics when the subwoofer is combined with a typical front speaker system.

When combined with 10 cm (4″) or 13 cm (5″) acoustic suspension, 2-way system front speakers

When combined with 20 cm (8″) or 25 cm (10″) acoustic suspension, 2-way system front speakers

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.
