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. 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 (except for Scandinavian models). Simply insert the Banana Plug connector into the corresponding terminal. How to Connect: Red: positive (+) Black: negative (-)  Ž Œ 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. ABOUT THE ACCESSORY TERMINALS AC OUTLETS (SWITCHED) (Europe and General models 3 SWITCHED OUTLETS (Australia and U.K. models 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 POWER 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 OUTLETS is 200 watts. PRE OUT/MAIN IN terminals Removing the jumper pins enables this unit to independently perform the functions of a control amplifier and a power amplifier. These terminals are for connection of a signalprocessing system such as a graphic equalizer or sound processor. If a sound processor or other component is connected, the VOLUME control of this unit can be used for overall adjustment of the level of sound. To connect such a unit, remove the jumper pins from the PRE OUT/MAIN IN terminals, connect the inputs of that unit to the PRE OUT terminals and its outputs to the MAIN IN terminals. For details, refer to the owner's manual included with the unit to be connected. REMOTE CONTROL (PHONO) connector If you have a YAMAHA turntable with a terminal for remote control, connect it to this connector by using the cable provided with the turntable. This connection allows you to control the turntable from the provided remote control transmitter. 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. 6
