The supplied speaker cable labels are also color-coded and
you should attach them to the positive (+) side of each
speaker cable in accordance with the table above. Then all
you need to do is to match the color of each label to the
corresponding speaker terminal.
Speaker Connection Precautions
Read the following before connecting your speakers:
• 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 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 negative (–)
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.
• Make sure the metal core of the wire does not have
contact with the AV receiver's rear panel. Doing so may
Color damage the AV receiver.

• Don't connect one speaker to several terminals.

To find the best position for your subwoofer, while playing
a movie or some music with good bass, experiment by
placing your subwoofer at various positions within the
room, and choose the one that provides the most satisfying
results.
You can connect the powered subwoofer with two
SUBWOOFER PRE OUT jacks respectively.
The same signal is output from each jack.
Tip
• If your subwoofer is unpowered and you're using an external
amplifier, connect the subwoofer pre out jack to an input on the
amplifier.
