CONNECTING SPEAKERS
• 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 8 Ω 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 16
Ω 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.
