ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY II Twisted Flare Port 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. Today’s bass reflex speakers use a Helmholtz resonator to improve their bass reproduction.
FEATURES PLACEMENT • This subwoofer system employs Advanced Yamaha Active Servo Technology II, which Yamaha has developed for the production of higher quality, superbass sound. 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.
CONTROLS AND THEIR FUNCTIONS Check the model number of your subwoofer on the label on the rear panel.
CONTROLS AND THEIR FUNCTIONS 1 Indicator Green: The subwoofer is turned on. Red: The Automatic power-switching function has activated, and the subwoofer is in standby mode. Off: The subwoofer is turned off. 9 B.A.S.S. (Bass Action Selector System) switch (NS-SW300 only) ( page 11) When this switch is set to MUSIC, the bass sound in audio software is well reproduced. When the switch is set to MOVIE, the bass sound in video software is well reproduced. 2 VOLUME control ( page 11) Adjusts the volume level.
CONNECTIONS Choose one of the following connection methods most suitable for your audio system. 1 Choose this method if your amplifier has line output (pin jack) terminal(s). ( page 5, 6) 2 Choose this method if your amplifier has no line output (pin jack) terminals. ( page 7, 8) 1 Notes • Unplug the subwoofer and other audio/video components before making connections, and do not plug them in until all connections are completed.
Example: Connecting two subwoofers NS-SW200 NS-SW300 Subwoofer Subwoofer Subwoofer Subwoofer 1 Amplifier or receiver 1 1 1 1 Mono pin cable Amplifier or receiver 1 Mono pin cable 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.
2 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 two subwoofers NS-SW200 NS-SW300 Right front speaker Left front speaker Speaker output terminals Amplifier or receiver Speaker output terminals Subwoofer Left front speaker Right front speaker Amplifier or receiver Subwoofer Subwoofer Subwoofer ■ Example: Connecting the subwoofer to an amplifier featuring two sets of speaker output terminals (A and B) that can output sound signals simultaneously Set the amplifier so that both sets of speaker output terminals (A and B) will output sound
Connecting to the INPUT1/OUTPUT terminals of the subwoofer Notes • 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.
System connections AUTOMATIC POWER-SWITCHING FUNCTION 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. 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.
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 1. Set the VOLUME control to minimum (0). 2. 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. 3. Make sure that the POWER switch is set to the ON position, then set the STANDBY/ PHASE switch In most situations, set this switch to select the reverse mode.
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.
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 STANDBY/ON switch is set the ON position. The power plug is not securely connected. Connect it securely.
