User manual PIONEER F-Z91L

[. . . ] The equipment should be disconnected by removing the mains plug from the wall socket when left unused for a long period of time (for example, when on vacation). To prevent a fire hazard, do not place any naked flame sources (such as a lighted candle) on the equipment. When installing this unit, make sure to leave space around the unit for ventilation to improve heat radiation (at least 15 cm at top, 15 cm at rear, and 15 cm at each side). CAUTION The POWER switch on this unit will not completely shut off all power from the AC outlet. [. . . ] 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 F-Z91L is especially effective. 1 Left speaker 2 Right speaker 3 Recommended installation range for the subwoofer 4 Listening position The subwoofer plays back the bass in monaural, making use of the fact that the human ear is not very sensitive to the direction of low-pitched sound. Because of this, the subwoofer can be installed almost anywhere. If it is installed too far away, however, the sound from the other speakers may become unnatural. The frequency characteristics of the F-Z91L combined with small-size speakers are shown below. As shown in these figures, the low frequency range is improved. These special characteristics are obtained in an echoless chamber. The effect of an additional F-Z91L in an ordinary listening room is better than the chart indicates when positioned adequately. Front left speaker Center speaker Front right speaker Subwoofer Listening area Rear left speaker Rear right speaker Keep the unit away from devices such as cassette decks which are sensitive to magnetic fields. The subwoofer is not magnetically shielded and so should not be placed near a CRTbased TV or color monitor. Magnetic storage media (such as floppy discs and tape or video cassettes) should also not be kept close to the subwoofer. Auto standby function The power is automatically set to the standby mode (off) if there is no input signal for approximately 12 minutes (the power indicator turns red). The power automatically turns on when a signal is input. There may be cases where a connected component outputs noise or some other non-audio signal which causes this system to automatically power on when in Auto Standby mode. If this happens, switch off the Auto Standby mode and switch the system on/off manually. 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. 6 Line Level Output terminal (LINE OUT) Used for connecting other equipment through the amplifier. The signal output from this jack is not affected in any way by the settings of the variouscontrols on the unit. 1 Power Indicator (STANDBY/ON) Lights blue when the power has been switched ON. Lights red when the unit is in the standby condition. nOTE: · The power is still supplied even when the power indicator is off. The power plug (interrupter) must be unplugged in order to completely cut the power supply. [. . . ] Power supply plug is not correctly inserted. Turn the VOLUME knob counter-clockwise to lower the level. Turn the amplifier's output level (volume, bass control, bass boost) counterclockwise to lower the level. Place the subwoofer a good distance from speakers. [. . . ]
