Connecting the AV receiver
—Continued
Using Dipole Speakers
You can use dipole speakers for the surround left and
right, surround back left and right speakers. Dipole
speakers output the same sound in two directions.
Dipole speakers typically have an arrow printed on them
to indicate how they should be positioned. The surround
left and right dipole speakers should be positioned so
that their arrows point toward the TV/screen, while the
surround back left and right and front high left and right
and front wide left and right dipole speakers should be
positioned so that their arrows point toward each other,
as shown.
Speaker Connection Precautions
Read the following before connecting your speakers:
• You can connect speakers with an impedance of
between 4 and 16 ohms. If the impedance of any of the
connected speakers is 4 ohms or more, but less than 6
ohms, be sure to set the minimum speaker impedance
to “4ohms” (see page 51). If you use speakers with a
lower impedance, and use the amplifier at high vol-
ume levels for a long period of time, the built-in pro-
tection circuit may be activated.
• Disconnect the power cord from the wall outlet before
making any connections.
• Read the instructions supplied with your speakers.
• Pay close attention to speaker wiring polarity. In other
words, connect positive (+) terminals only to positive
(+) terminals, and negative (–) terminals only to nega-
tive (–) terminals. If you get them the wrong way
around, the sound will be out of phase and will sound
unnatural.
• Unnecessarily long, or very thin speaker cables may
affect the sound quality and should be avoided.
• If you use 4 or 5 speakers, connect each of the two
surround speakers to the SURR/ZONE 3 L/R termi-
nals. Do not connect them to the SURR
BACK/ZONE 2 L/R, FRONT WIDE L/R, or FRONT
HIGH L/R terminals.
• Be careful not to short the
positive and negative wires.
Doing so may damage the AV
receiver.
• Make sure the metal core of
the wire does not have contact
with the AV receiver’s rear
panel. Doing so may damage the AV receiver.
• Don’t connect more than one cable to each speaker
terminal. Doing so may damage the AV receiver.
• Don’t connect one speaker to several terminals.
