User manual PIONEER S-W80S

[. . . ] The effect of an additional S-W80S 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-W80S 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. The subwoofer plays back the bass in monaural, making use of the fact that the human ear loses the sense of direction of lowpitched sound. [. . . ] If the problem persists, place the speaker system away from the television set. Please install this unit away from the antenna cable of the tuner, as noise can be caused with installation close to the antenna cable. In such a case, use this unit at a position away from the antenna and the antenna cable, or when playback of extra bass is not required, switch off the power for this unit. Do not pull out the plug by tugging the cord and never touch the power cord when your hands are wet as this could cause a short circuit or electric shock. The power cords should be routed such that they are not likely to be stepped on. A damaged power cord can cause a fire or give you an electrical shock. When you find it damaged, ask your nearest PIONEER authorized service center or your dealer for a replacement. When the surfaces are very dirty, wipe with a soft cloth dipped in some neutral cleanser diluted five or six times with water, and wrung out well, and then wipe again with a dry cloth. Never use thinners, benzine, insecticide sprays and other chemicals on or near this unit, since these will corrode the surfaces. When pressed, power is turned ON; when pressed again, power is turned OFF. When depressed (_ 180°), the output phase becomes the reverse of the input signal, and when raised (-- 0° ), it is in the same phase as the input signal. But when the sound connection between the subwoofer and the left and right speakers sounds unnatural, try switching to 180° and set the switch in the position where the sound is natural. With this unit, the bass level can be independently set, so do not turn up the bass on the stereo amplifier. When the speakers output terminals on the stereo amplifier are connected to this unit's SPEAKER LEVEL INPUT terminals 9 and used as the unit's input signal, these terminals are used to connect the left and right speakers via 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 PRE-OUT 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. nOTES: ÷ 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. [. . . ] 1 No power is being supplied (Indicator does not light up when power switch is turned on. Turn the amplifier's output level (volume, bass control, bass boost) counter-clockwise to lower the level. Increase the distance between the AM or FM antenna (for indoor use) and this unit. NOTE: Specifications and design subject to possible modification without notice, due to improvements. [. . . ]
