The remote control transmits a directional infrared ray. Be sure to aim the remote control directly at the remote control sensor on the main unit during operation. Replacing the batteries Change all of the batteries if you notice conditions such as the operation range of the remote control decreases. Handling the remote control Notes • Do not use an old battery together with a new one. • Do not use different types of batteries (for example, alkaline and manganese) together. Each type of battery has its own characteristics even if they are similar in shape. • If the batteries run out, immediately remove them from the remote control to prevent an explosion or acid leak. • Dispose of the batteries according to the regional regulations. • If a battery starts leaking, dispose of it immediately. Be careful not to let leaking battery acid come into contact with your skin or clothing. Before inserting new batteries, wipe the compartment clean. Be careful not to drop the remote control. Be careful not to spill liquid on the remote control. Do not leave the remote control in the following places: – hot or humid places, such as near a heater or in a bathroom – extremely cold places – dusty places 5 En  PLACEMENT The position of the subwoofer is not so critical because bass sound is not highly directional. For a sonorous sound field, the use of two subwoofers is recommended, although you can obtain a good effect with one subwoofer. ( : subwoofer, : front speaker) ■When using one subwoofer ■When using two subwoofers Place the subwoofer on the outside of either the right or the left front speaker. Place the subwoofers on the outside of each front speaker. A y If the subwoofer is placed directly facing the wall, the bass sound may lessen because the sound from the subwoofer and the sound reflected by the wall may cancel each other out. To prevent this from happening, face the subwoofer obliquely to the wall ( A or B ). 6 En B  CONNECTIONS See pages 7 - 8 when your amplifier has subwoofer (line out) terminal(s), or see pages 9 - 11 when your amplifier has no subwoofer (line out) terminal. Notes • Do not connect the power cord of this unit and other components into an AC outlet until all connections between components are completed. • Be sure to connect the left channel (L), right channel (R), “+” (red) and “–” (black) properly. Also, refer to the owner’s manual of your component to be connected to this unit. • The connection methods or the names of the terminals may differ depending on the component. Refer to the owner’s manual of your component as well. 1 Connecting to the amplifier equipped with subwoofer (line out) terminal(s) When your amplifier has a one-channel subwoofer terminal Connect the subwoofer (or low pass etc.) terminal of your amplifier to the INPUT 3 ( L /MONO) terminal of this unit using a commercially available mono pin cable.

This technology 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 cabinet capacity 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.

If the problem you are experiencing is not listed below or if the instructions given below do not help, disconnect the power cord and contact your authorized Yamaha dealer or service center. Problem Cause Remedy Power is not supplied even though the STANDBY/ON switch is pressed. The power plug is not securely connected. Connect it securely. The POWER switch is set to the OFF position. Set the POWER switch to the ON position. No sound. The volume is set to the minimum (0). Raise the volume. Speaker cables are not connected securely. Connect them securely. The signals from the amplifier are too low. Increase the volume of the amplifier or the component connected to the amplifier. The signal from the subwoofer output terminal of the amplifier is not output. Check the speaker mode setting on the amplifier. Speaker cables are not connected correctly. Connect them correctly, that is L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. Setting of the phase is not proper. Set the phase to the other position. A source sound with few bass frequencies is being played. Play a source sound with bass frequencies. Set the H-CUT to a higher position. It is influenced by standing waves. Reposition this unit or break up the parallel surface by placing bookshelves etc. along the walls. Wrong distance or angle. Use the remote control within a maximum range of 6 m and no more then 30 degrees off-axis from the front panel. Direct sunlight or lighting from an inverter type of fluorescent lamp etc. is striking the remote control sensor of this unit. Reposition this unit. The batteries are weak. Replace all batteries. This unit is not turned on with the remote control of the amplifier. (when setting “Operating the power of this unit using the remote control of your amplifier”) Wrong distance or angle. Place this unit within the operating range of the remote control of the amplifier. The household breaker goes off. This unit consumes much electricity when a high level signal is input to this unit. Turn down the volume on the amplifier etc. connected to this unit or cut off the power of other unused equipment. Sound level is too low. The remote control does not work. Notes • When an excessive level of signal is input to this unit for 5 to 15 minutes, the POWER indicator starts flashing to alarm you of the danger of damaging the power amplifier and speaker of this unit. If the signal input lasts for 5 minutes more, this unit turns into the standby mode automatically. • When an enormous amount of signal is input, the power of this unit is turned off immediately. To turn on this unit again, press STANDBY/ON switch on the front panel. 18 En  SPECIFICATIONS Type ....
