Connecting the AV Receiver
—Continued
Speaker Connection Precautions
Read the following before connecting your speakers:
• North American models: Only connect speakers 
with an impedance of 6 ohms or higher. If you use 
speakers with a lower impedance, and use the ampli-
fier at high volume levels for a long period of time, the 
built-in protection circuit may be activated.
• Other 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 “4 ohms” (see page 47). 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 SURROUND SPEAKERS 
terminals. Do not connect them to the SURROUND 
BACK SPEAKERS 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
The following illustration shows which speaker should 
be connected to each pair of terminals.
If you’re using only one surround back speaker, connect 
it to the left (L) SURROUND BACK SPEAKERS termi-
nals.
1
Strip about 5/8" (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.
