CAUTION: READ THIS BEFORE OPERATING YOUR UNIT.
●
To assure the finest performance, please read this manual carefully. Keep it in a safe place for future reference.
●
Install the speakers in a cool, dry, clean place – away from windows, heat sources, sources of excessive vibration, dust, moisture and cold. Avoid sources of humming
(transformers, motors).
●
To prevent fire or electrical shock, do not expose the speakers to rain or water.
●
To prevent the enclosure from warping or discoloring, do not place the speakers where it will be exposed to direct sunlight or excessive humidity.
●
Do not place the speakers where it is liable to be knocked over or struck by falling objects. Stable placement will also ensure better sound performance.
●
Placing the speakers on the same shelf or rack as the turntable can result in feedback.
●
Any time you note distortion, reduce the volume control on your amplifier to a lower setting. Never allow your amplifier to be driven into “clipping”. Otherwise the speakers may be damaged.
●
When using an amplifier with a rated output power higher than the nominal input power of the speakers, care should be taken never to exceed the speakers’ maximum input.
●
As these speakers contain strong magnets (though all of them are magnetically shielded types), avoid placing watches, magnetic tapes, etc. near them. Also, placing the speakers near a TV set may impair picture color. If this happens, move the speakers away from TV set.
●
Do not attempt to clean the speakers with chemical solvents; this might damage the finish. Use a clean, dry cloth.
●
Secure placement or installation is the owner’s responsibility.
YAMAHA shall not be liable for any accident caused by improper placement or installation of the speakers.
For canadian customers

<
For SW-P30 only
>
Never open the cabinet. If something drops into the set, contact your dealer.
●
Do not use force on switches, controls or connection cords.
When moving the unit, first disconnect the power plug and the cords connected to other equipment. Never pull the cords itself.
●
Be sure to read the “TROUBLESHOOTING” section regarding common operating errors before concluding that the unit is faulty.
●
When not planning to use this unit for long periods of time
(ie., vacation, etc.), disconnect the AC power plug from the wall outlet.
●
To prevent lightning damage, disconnect the AC power plug when there is an electrical storm.
●
Since this unit has a built-in power amplifier, heat will radiate from the rear panel. Therefore, place the unit apart from the walls, allowing enough space above, behind and on the both sides of the unit to prevent fire and damage. Also, do not position with the rear panel facing down on the floor or other surface.
<
For Europe and Singapore models only
>
Be sure to allow a space of at least 20 cm above, behind and on the both sides of the unit.
●
Super-bass frequencies reproduced by this unit may cause a turntable to generate a howling sound. In such a case, move this unit away from the turntable.
●
If you hear distortion (i.e., unnatural, intermittent “rapping” or
“hammering” sounds) coming from this unit, reduce the volume level. Extremely loud playing of a movie soundtrack’s low frequency, bass-heavy sounds or similarly loud popular music passages can damage this speaker system.
This unit is not disconnected from the AC power source as long as it is connected to the wall outlet, even if this unit itself is turned off. This state is called the standby mode.
In this state, this unit is designed to consume a very small quantity of power.

Placing speakers
Main speakers:
On both sides of the TV and almost the same height as the TV.
Effect speakers:
Behind your listening position, facing slightly inward. Nearly 1.8 m (approx. 6 feet) up from the floor.
Center speaker:
Precisely between the main speakers.
Subwoofer:
The position of the subwoofer is not so critical because low bass tones are not highly directional.
Refer to “Placing the subwoofer” shown below for a recommended positioning of the subwoofer.

Automatic power-switching function
When you play a source, the power of this unit turns on automatically by sensing audio signals input to this unit.
This unit turns into the standby mode automatically if the source being played is stopped or the input signal is cut off for several minutes.
This function will operate by sensing a certain level of low frequency input signal. Its sensitivity is high in the HIGH position and low in the LOW position of the AUTO
STANDBY switch. Set this switch to whichever position you like. In the HIGH position, the power will turn on even with a low level of input signal, but on the other hand this unit may not turn into the standby mode when there is an input signal even if its level is extremely low.
* There may be a case that the power turns on unexpectedly by sensing noise from other appliances. If it occurs, set the AUTO STANDBY switch to the OFF or
LOW position.
* The level of low frequency input signal differs with each source, and each different part on the same source. So, this function may not operate properly depending on some sources.
This function is available only when the power of this unit is on (by setting the POWER switch (
8
) to “ON”).

•
Once the volume balance between the subwoofer and the main speakers is adjusted, you can adjust the volume of your whole sound system by using only the amplifier’s volume control.
However, if you change the main speakers NS-M103 to others, you must make this adjustment again.
•
For adjusting the VOLUME control and the HIGH CUT switch, refer to “FREQUENCY CHARACTERISTICS” shown below.
Note about setting the HIGH CUT switch
This system is designed so that the optimum tone balance between the subwoofer and the main speakers is obtained when this switch is set to the LOW position. However, the tone balance may change depending on the room size, the distance from the subwoofer to the main speakers, and so on.
So, if necessary, switch it to the HIGH position.

ACTIVE SERVO TECHNOLOGY (for SW-P30)
The theory of Active Servo Technology is based upon two Thus it is this problem that is resolved through the major factors, the Helmholtz resonator and negativeemployment of a design in which the amplifier functions to impedance drive. Active Servo Processing speakers reproduce the bass frequencies through an “air woofer”, which is a port or opening in the speaker’s cabinet. This opening is used instead of, and performs the functions of, a woofer in a conventionally designed speaker system.
Thus, signals of low amplitude within the cabinet can, according to the Helmholtz resonance theory, be output from this opening as waves of great amplitude if the design is such that the size of the opening and the volume of the cabinet are in the correct proportion to satisfy a certain ratio.
In order to accomplish this, moreover, the amplitudes within the cabinet must be both precise and of sufficient power because these amplitudes must overcome the
“load” presented by the air that exists within the cabinet.
supply special signals. If the electrical resistance of the voice coil could be reduced to zero, the movement of the speaker unit would become linear with respect to signal voltage, and, to accomplish this, a special negative-impedance output-drive amplifier for subtracting output impedance of the amplifier is used.
By employing negative-impedance drive circuits, the amplifier is able to generate precise, low-amplitude low-frequency waves with superior damping characteristics, and these waves are then radiated from the cabinet opening as highamplitude signals. The system can, therefore, by employing the negative-impedance output drive amplifier and a speaker cabinet with the Helmholtz resonator, reproduce an extremely wide range of frequencies with amazing sound quality and less distortion.
The features described above, then, are combined to be the fundamental structure of the Active Servo Technology.
