English CONNECTING SPEAKERS Connect the SPEAKERS terminals to your speakers with wire of the proper gauge, cut as short as possible. If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is, + and - markings are observed. If these wires are reversed, the sound will be unnatural and will lack bass. Do not let the bare speaker wires touch each other and do not let them touch the metal parts of this unit as this could damage this unit and/or speakers. How to Connect: Red: positive (+) Black: negative (-) 2 1 3 Œ Unscrew the knob.  Insert the bare wire. [Remove approx. 5mm (1/4") insulation from the speaker wires.] Ž Tighten the knob and secure the wire. q One or two speaker systems can be connected to this unit. If you connect only one speaker system, connect it to either the SPEAKERS A or B terminals. q Use speakers with the specified impedance shown on the rear of this unit. q Banana Plug connections are also possible. Simply insert the Banana Plug connector into the corresponding terminal. IMPEDANCE SELECTOR switch Be sure to switch this only when the power to this unit is not on. Select the position whose requirements your speaker system meets. 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 closely. If so, set the switch to either end closely. (General model) IMPEDANCE SELECTOR SET BEFORE POWER ON A OR B:4ΩMIN./SPEAKER A + B:8ΩMIN./SPEAKER A OR B:8ΩMIN./SPEAKER A + B:l6ΩMIN./SPEAKER (Left position) If you use one pair of speakers, the impedance of each speaker must be 4Ω or higher. If you use two pairs of speakers, the impedance of each speaker must be 8Ω or higher. (Right position) If you use one pair of speakers, the impedance of each speaker must be 8Ω or higher. If you use two pairs of speakers, the impedance of each speaker must be 16Ω or higher. ABOUT THE ACCESSORY TERMINALS 1 * AC OUTLET(S) (SWITCHED) (Europe and General models 3 SWITCHED OUTLETS (U.K. model 1 SWITCHED OUTLET Use these to connect the power cords from your components to this unit. The power to the SWITCHED outlets is controlled by this unit's STANDBY/ON switch or the provided remote control transmitter's POWER key. These outlets will supply power to any component whenever this unit is turned on. The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLET(S) is 100 watts. 2 * GND terminal (For turntable use) Connecting the ground wire of the turntable to this terminal will normally minimize hum, but in some cases better results may be obtained with the ground wire disconnected. 7
