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 on or to the standby mode 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 balance between the subwoofer and the front speakers by following the procedures described below. Rear panel INPUT /MONO AUTO STANDBY OFF LOW HIGH OFF POWER ON VOLUME 0 10 INPUT /MONO AUTO STANDBY OFF LOW HIGH VOLUME 0 10 OFF POWER ON3 1, 5 English 1 Set the VOLUME control to minimum (0). 2 Turn on the power of all the other components. 3 Press the POWER switch to the ON position. * The power indicator on the front panel lights up in green. 4 Play a source containing low-frequency components and adjust the amplifier’s volume control to the desired listening level. 5 Increase the volume gradually to adjust the volume balance between the subwoofer and the front speakers. Normally, set the control to the level where you can obtain a little more bass effect than when this unit is not used. Frequency characteristics Fig. 1 shows the frequency characteristics of the subwoofer. 40 50 60 70 80 90 100 dB 20 50 100 200 500 Hz Fig. 1 . Once the volume balance between the subwoofer and the front speakers is adjusted, you can adjust the volume of your whole sound system by using the amplifier’s volume control. However, if you change the front speakers (NX-E130) to others, you must make this adjustment again. . For adjusting the VOLUME control, refer to “Frequency characteristics” below. Fig. 2 shows the frequency characteristics when the subwoofer is combined with NX-E130 and the subwoofer’s volume level is set to the figured position. 100 dB 90 VOLUME 80 SW-P130 NX-E130 20 50 100 200 500 Hz 70 60 0 I0 50 40 Fig. 2 ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY (for SW-P130) ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY (for SW-P130) 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, low- frequency 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.

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. English Problem Cause What to Do No sound. Speaker cables are not connected securely. Connect them securely. Sound level is too low. Speaker cables are not connected correctly. Connect them correctly, that is L (left) to L, R (right) to R, “+” to “+” and “–” to “...
