SETTING UP THE SPEAKERS
Before making connections, place all speakers in their respective positions. The positioning of the speakers is important because it controls the whole sound quality of this system. Place the speakers depending on your listening position by following the instructions below.

Speaker configuration

<NS-P230>
This speaker package employs a 6 speaker configuration: 2 main speakers, 2 rear speakers, a center speaker and a subwoofer. The main speakers emit main source sound. The rear speakers emit surround sounds, and the center speaker emits center sounds (dialog etc.). The subwoofer emits reinforcing low frequencies on your audio system.

Placing speakers

Main speakers: Rear speakers: On both sides of and at approximately the same height as the TV set. Behind your listening position, facing slightly inward. About 1.8 m (approx. 6 feet) from the floor. Precisely between the main speakers.

Center speaker:

Rear center speaker (for NS-P236): Precisely between the rear speakers. Subwoofer: The position of the subwoofer is not so critical because low bass tones are not highly directional. Refer to Placing the subwoofer below for a recommended positioning of the subwoofer.

<NS-P236>

This speaker package employs a 7 speaker configuration: 2 main speakers, 2 rear speakers, a center speaker, a rear center speaker and a subwoofer. The main speakers emit main source sound. The rear and rear center speakers emit surround sounds, and the center speaker emits center sounds (dialog etc.). The subwoofer emits reinforcing low frequencies on your audio system. Note In this speaker package, the same speakers (NX-230P) are used for the main and rear speakers (and rear center speaker for NS-P236).

Placing the subwoofer
It is recommended to place the subwoofer on the outside of either the right or the left main speaker. (See fig. .) The placement shown in fig. is also possible, however, if the subwoofer system is placed directly facing the wall, the bass effect may die because the sound from it and the sound reflected by the wall may cancel out each other. To prevent this from happening, face the subwoofer system at an angle as shown in fig. Note There may be a case that you cannot obtain enough superbass sounds from the subwoofer when listening in the center of the room. This is because standing waves have been developed between two parallel walls and they cancel the bass sounds. In such a case, face the subwoofer obliquely to the wall. It also may be necessary to break up the parallel surfaces by placing bookshelves etc. along the walls.

SPS-80

* The SPS-80 is not available in some areas.
I Placing the the main/rear speakers (and rear center speaker for NS-P236)
When placing the speakers on a flat surface, attach the included nonskid pads to the corners on the bottom of the speakers as shown on the left. This prevents the speakers from sliding around. Nonskid pad * For NS-P236, the nonskid pads include four spare ones.
If you want to mount a speaker on a commercially available speaker stand for the main/rear speakers (and rear center speaker for NS-P236)
The provided mounting bracket with 1 pair of screw holes (at an interval of 60 mm) can be used to mount the speaker on a speaker stand. * Those screw holes can be used with M4 screws only.

Mounting bracket

Attach the bracket to the bottom of the speaker by using the provided screw so that the convex part of the bracket fits in the grooved part on the bottom of the speaker as shown on the left. Mount the speaker on the speaker stand by using the screw holes on the bracket.
Note The mounting bracket is provided for each speaker.

Automatic power-switching function
If the source being played is stopped and the input signal is cut off for 7 to 8 minutes, the subwoofer automatically switches to the standby mode. (When the subwoofer switches to the standby mode by the automatic powerswitching function, the power indicator lights up in red.) When you play a source again, the power of the subwoofer turns on automatically by sensing audio signals input to the subwoofer. This function will operate by sensing a certain level of low frequency input signal. Usually set the AUTO STANDBY switch to the LOW position. However, if the power is not switched to ON or STANDBY smoothly, set the switch to the HIGH position. In the HIGH position, the power will turn on even with a low level of input signal. But please be aware that the subwoofer may not switch to the standby mode when there is an extremely low input signal. * The power might turn on unexpectedly by sensing noise from other appliances. If that occurs, set the AUTO STANDBY switch to the OFF position and use the POWER switch to switch the power between ON and OFF manually. * This function detects the low-frequency components below 200 Hz of the input signals (i.e., the explosion in the action movie, the sound of the bass guitar or the bass drum, etc.). * The minutes required to switch the subwoofer to the standby mode might change by sensing noise from other appliances. This function is available only when the power of the subwoofer is on (by pressing the POWER switch).

Adjusting the subwoofer before use
Before using the subwoofer, adjust the subwoofer to obtain the optimum volume and tone balance between the subwoofer and the main speakers by following the procedures described below.

Rear panel

AUTO STANDBY
Set the VOLUME control to minimum (0). Turn on the power of all the other components. Press the POWER switch to the ON position.
* The power indicator on the front panel lights up in green.
Increase the volume gradually to adjust the volume balance between the subwoofer and the main speakers.
Normally, set the control to the level where you can obtain a little more bass effect than when this unit is not used. If the desired response cannot be obtained, adjust the HIGH CUT switch and the VOLUME control again.
Play a source containing low-frequency components and adjust the amplifiers volume control to the desired listening level. Set the HIGH CUT switch to the LOW or HIGH position.
This subwoofer 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. The tone balance may change, however, depending on the room size, the distance from the subwoofer to the main speakers, and so on. If necessary, switch it to the HIGH position.
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 the amplifiers volume control. However, if you change the main speakers (NX-230P) to others, you must make this adjustment again. For adjusting the VOLUME control and the HIGH CUT switch, refer to Frequency characteristics below.
Frequency characteristics
Fig. 1 shows the frequency characteristics of the subwoofer with each position (HIGH/LOW) of the HIGH CUT switch. Fig. 2 shows the optimum volume level with the HIGH CUT switch at the HIGH position, and the frequency characteristics when the subwoofer is combined with NX230P.

ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY (for YST-SW005)
The theory of Yamaha Active Servo Technology has been based upon two major factors, the Helmholtz resonator and negative-impedance drive. Active Servo Processing speakers reproduce the bass frequencies through an air woofer, which is a port or opening in the speakers 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 outputted from this opening as waves of great amplitude if 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. Thus it is this problem that is resolved through the employment of a new design in which the amplifier supplies 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. 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, lowfrequency waves with superior damping characteristics. These waves are then radiated from the cabinet opening as high-amplitude 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 conventional Yamaha Active Servo Technology. Our new Active Servo Technology Advanced Yamaha Active Servo Technology adopted Advanced Negative Impedance Converter (ANIC) circuits, which allows the conventional negative impedance converter to dynamically vary in order to select an optimum value for speaker impedance variation. With this new ANIC circuits, Advanced Yamaha Active Servo Technology can provide more stable performance and improved sound pressure compared with the conventional Yamaha Active Servo Technology, resulting in more natural and dynamic bass reproduction.
