Speaker Connection Precautions
Read the following before connecting your speakers:
•
American model only: Only connect speakers with
an impedance of 6 ohms or higher. 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.
• 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 Mini-
mum Speaker Impedance to “4 ohms” (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 to only positive
(+) terminals, and negative (–) terminals to only 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.
• Be careful not to short the
positive and negative wires.
Doing so may damage the AV
receiver.
• Don’t connect more than one
cable to each speaker termi-
nal. 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.
