English s GND terminal (For turntable use) Connecting the ground wire of the turntable to the GND terminal will normally minimize hum, but in some cases better results may be obtained with the ground wire disconnected. s PRE OUT/MAIN IN terminals Removing the jumper pins from the PRE OUT/MAIN IN terminals enables this unit to operate separately as a control amplifier and a power amplifier. These terminals are used for connecting a signal-processing system such as a graphic equalizer or a surround-sound processor to this unit. If such an external unit is connected to these terminals, the VOLUME control of this unit can be used for adjusting the overall sound level. To connect an external unit, first remove the jumper pins from the PRE OUT/MAIN IN terminals, and then connect the input terminals of that unit to the PRE OUT terminals or its output terminals to the MAIN IN terminals. For details, refer to the owner's manual included with the unit to be connected. COUPLER MAIN IN PRE OUT R L CONNECTIONS s AC OUTLET(S) (SWITCHED) (U.S.A. and Canada models 2 SWITCHED OUTLETS (Australia model 1 SWITCHED OUTLET Use these to connect the power cords from your A/V 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. s REMOTE CONTROL (IN, OUT) terminals These terminals are used for custom installation system. When this unit is connected to the components for custom installation system, you can operate this unit with the system remote control. Connect the REMOTE CONTROL IN terminal of this unit to the output terminal of the central controller for custom installation system. By connecting the REMOTE CONTROL OUT terminal of this unit to the REMOTE CONTROL IN terminal of the other component, you can also operate the component with the system remote control. In this way, up to 6 components can be connected in series. Notes • When you do not use the PRE OUT/MAIN IN terminals, never remove the jumper pins from these terminals. If removed, no sound will be outputted from this unit. • When you use this unit with an external unit connected to the PRE OUT and MAIN IN terminals, make sure that the CD DIRECT AMP switch and the PURE DIRECT switch on the front panel are turned off. • When you use this unit as a power amplifier, connect the output terminals of an external control amplifier etc. to this unit's MAIN IN terminals. In this case, this unit's controls will not function except the PHONES jack and the SPEAKERS switches. Use the controls on the external control amplifier to make volume adjustment etc. E-7
