PREPARATION Note on main speaker connections: One or two speaker systems can be connected to this unit. If you use only one speaker system, connect it to either the SPEAKERS A or B terminals. Note on a subwoofer connection: You may wish to add a subwoofer to reinforce low frequencies or to output low bass sound from the subwoofer channel when reproducing discrete signals. When using a subwoofer, connect the SUBWOOFER terminal of this unit to the INPUT terminal of the subwoofer amplifier, and connect the speaker terminals of the subwoofer amplifier to the subwoofer. With some subwoofers, including the Yamaha Active Servo Processing Subwoofer System, the amplifier and subwoofer are in the same unit. Such a subwoofer needs only the connection between the SUBWOOFER terminal of this unit and the INPUT terminal of the subwoofer. (Refer to page 23 for details about the SUBWOOFER terminal.) Ⅵ IMPEDANCE SELECTOR switch WARNING Do not change the IMPEDANCE SELECTOR switch setting while the power to this unit is on, otherwise this unit may be damaged. IF THIS UNIT FAILS TO TURN ON WHEN THE STANDBY/ON SWITCH IS PRESSED: The IMPEDANCE SELECTOR switch may not be set to either end. If so, set the switch to either end when this unit is in the standby mode. (Europe model) SPEAKERS REAR (SURROUND ) CAUTION SEE INSTRUCTION MANUAL FOR CORRECT SETTING.
