4. CONNECTING SPEAKERS

ENGLISH

•You can connect up to four pairs of speakers to this receiver and select the various combinations of speakers according to your tastes.

•The speakers C and D can be installed in the main room as the speakers A and B can or in the another room (ROOM2) for ROOM2 playback. (For details, refer to "ROOM2 PLAYBACK" on page 24.)

•Be sure to connect speakers firmly and correctly according to the channel (left and right) and the polarity (+ and -).

•If the connections are faulty, no sound will be heard from the speakers, and if the polarity of the speaker connection is incorrect, the sound will be unnatural and lack bass.

Notes :

•For safe amplifier operation, use the speakers with impedance of over 8Ω when you connect a pair terminals of SPEAKER A and B terminals or/and a pair terminals of

SPEAKER C and D terminals and use the speakers with impedance of over 16Ω when you connect both SPEAKER A and B terminals or/and both SPEAKER C and D terminals.

•Do not let the bare speaker wires touch each other or any metal part of this receiver. This could damage this receiver and/or the speakers.
