Connecting the AV Receiver—Continued
Speaker Connection Precautions
Read the following before connecting your speakers:
• North American models: You can connect speakers
with an impedance of between 6 and 16 ohms. If you
use speakers with a lower impedance, and use the
amplifier at high volume levels for a long period of
time, the built-in amp protection circuit may be acti-
vated.
• Australian models: You can connect speakers with an
impedance of between 4 and 16 ohms. If the imped-
ance 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 44). If you
use speakers with a lower impedance, and use the
amplifier at high volume levels for a long period of
time, the built-in protection 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 L/R terminals. Do not
connect them to the SURR BACK 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.
Connecting the Speaker Cables
1
Strip 1/2"-5/8" (12-15 mm)
of insulation from the
ends of the speaker
cables, and twist the bare
wires tightly, as shown.
2
Unscrew the terminal.
3
Fully insert the bare
wires.
4
Screw the terminal tight.
