User manual PIONEER S-W8

[. . . ] In some countries or regions, the shape of the power plug and power outlet may sometimes differ from that shown in the explanatory drawings. However, the method of connecting and operating the unit is the same. 7 200 W power that serves video software playback such as Dolby* Digital with a wide dynamic range. 7 Equipped with a high-efficiency class D amplifier with a PWM system. [. . . ] These special characteristics are obtained in an echoless chamber. The effect of an additional S-W8 in an ordinary listening room is better than the chart indicates when positioned adequately. With playback of Dolby* Digital, establishment of a special channel for the subwoofer is recommended; and with playback of LFE (Low Frequency Effect: sound effect like the rumbling of the earth, whose purpose is to intensify the force of the video), the S-W8 is especially effective. This is because it has 5 channels in the 20Hz ­ 20kHz frequency range (front left and right, center, and rear left and right) and an independent channel for the subwoofer. Do not connect the ground cable if the LINE LEVEL OUTPUT jack has been connected. Connect the ground cable to both the signal ground jack (see A above) and to the receiver/amplifier of your system if there is a hum coming out of the speakers when they are connected. In the case where your receiver/amplifier does not have a specific connection (GND) for the ground cable, attach the cable (see B above) to a screw on the rear panel or the top cover of the unit. Before making or changing the connections, switch off the power switch and disconnect the power cord from the AC outlet. This connection is for a stereo amplifier or receiver equipped with a SUBWOOFER PREOUT terminal. If the stereo amplifier or receiver is not equipped with a SUBWOOFER PRE-OUT terminal, carry out a Speaker Level connection. Connect to the LINE LEVEL INPUT terminal on this unit, using the specially provided RCA plug cord. nOTE: When connected to the PRE-OUT terminal for surround center channel on the stereo amplifier or receiver, the bass is heard only on the center channel, so it will be insufficient. When the power of the stereo amplifier is turned off before the power of this unit is switched off, a shock sound may be generated. In this case, lower the subwoofer volume or turn off the power of this unit. If the stereo amplifier has a switched outlet, connect the power cable of this unit to this outlet. When the subwoofer volume is set to an extremely high level, howling may be caused when the power of the stereo amplifier is turned off or when the speaker switch is turned on. To prevent this, connect the power cable of this unit to the switched outlet of the stereo amplifier. If there is no switched outlet, lower the subwoofer volume or turn off the power of this unit before turning off the power of the stereo amplifier. Also, when using this unit at a high level, do not turn off the speaker switch of the stereo amplifier. When the LINE LEVEL INPUT terminal is connected, the SPEAKER LEVEL INPUT terminals cannot be used. There are 2 speaker level connection methods: Place the unit between the connection of the stereo amplifier's or receiver's speaker terminals and the left and right speakers. Make sure L (+), L (­), R (+), R (­) are correctly aligned. [. . . ] Investigate the other components and electrical appliances being used If the trouble cannot be rectified even after exercising the checks listed below, ask your nearest PIONEER authorized service center or your dealer to carry out repair work. (Indicator does not light up when power switch is turned on. Power supply plug is not correctly inserted. Turn the LEVEL knob counter-clockwise to lower the level. [. . . ]
