Connecting Your Speakers —Continued
Before you connect your speakers, read the following:
• Disconnect the power cord from the wall outlet.
• 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
odd.
• Only use 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.
• Unnecessarily long or very thin speaker cables may
affect the sound quality and should be avoided.
• Be careful not to short the posi-
tive and negative connections.
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.
• If you want to connect a single speaker instead of a
pair, connect it to either the left or right speaker termi-
nals, not both.
Attaching the Speaker Labels
The AV Receiver’s positive (+) speaker terminals are
color-coded for ease of identification. (The negative (–)
speaker terminals are all black.)
The supplied speaker labels are also color-coded and you
should attach them to the positive (+) side of each
speaker cable in accordance with the above table. All you
need to do then is to match the color of each label to the
corresponding speaker terminal.
Connecting the Speaker Cables
The following illustration shows which speakers should be connected to which terminals.

The SUBWOOFER PRE OUT should be connected to the
input on your powered subwoofer. If your subwoofer
doesn’t have an amp built-in, you’ll need to use an
external amp. See the manual supplied with your
subwoofer for more information.
