OUTPUT terminals (for driving speakers with external amplifiers) MAIN CENTER REAR (SURROUND) SUB WOOFER OUTPUT REAR (SURROUND) OUTPUT terminals These terminals are for rear channel line output. There is no connection to these terminals when you use the built-in amplifier. However, if you drive rear speakers with an external stereo power amplifier, connect the input terminals of the external amplifier (MAIN IN or AUX terminals of a power amplifier or an integrated amplifier) to these terminals. MAIN OUTPUT terminals These terminals are for main channel line output. There is no connection to these terminals when you use the built-in amplifier. However, if you drive main speakers with an external stereo power amplifier, connect the input terminals of the external amplifier (MAIN IN or AUX terminals of a power amplifier or an integrated amplifier) to these terminals. * Output signals from the MAIN OUTPUT terminals only are affected by the use of BASS, TREBLE, BALANCE controls and BASS EXTENSION switch. CENTER OUTPUT terminal This terminal is for center channel line output. There is no connection to this terminal when you use the built-in amplifier. However, if you drive a center speaker with an external power amplifier, connect the input terminal of the external amplifier to this terminal. SUBWOOFER OUTPUT terminal This terminal is for connecting with the input terminal of an amplifier for driving a subwoofer. When the input signals to this unit are in normal 2-channel stereo, this terminal outputs only frequencies below 200 Hz from the main and center channels. When discrete signals are input to this unit and are selected as the input source, this terminal outputs signals from the subwoofer channel. Note Output level of signals from all of these terminals are adjusted by the use of VOLUME control on the front panel or MASTER VOLUME keys on the remote control transmitter. IMPEDANCE SELECTOR switch Be sure to switch this only when the power of this unit is turned off. 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 POWER SWITCH IS PRESSED The IMPEDANCE SELECTOR switch may not be set to either end closely. If so, set the switch to either end closely. (Upper position) Rear: The impedance of each speaker must be 6Ω or higher. Center: If you use one center speaker, the impedance of the speaker must be 6Ω or higher. If you use two center speakers, the impedance of each speaker must be 3Ω or higher. Main: If you use one pair of main speakers, the impedance of each speaker must be 4Ω or higher. If you use two pairs of main speakers, the impedance of each speaker must be 8Ω or higher. 12 IMPEDANCE SELECTOR REAR 6ΩMIN. /SPEAKER CENTER SINGLE:6ΩMIN. /SPEAKER DUAL:3ΩMIN. /SPEAKER MAIN A OR B:4ΩMIN. /SPEAKER A B:8ΩMIN. /SPEAKER REAR 8ΩMIN. /SPEAKER CENTER SINGLE:8ΩMIN. /SPEAKER DUAL:4ΩMIN. /SPEAKER MAIN A OR B:8ΩMIN. /SPEAKER A B:I6ΩMIN. /SPEAKER (U.S.A. model) (Lower position) Rear: The impedance of each speaker must be 8Ω or higher.
