• Speakers should only be placed on sturdy, flat
surfaces that are free from vibration. Putting them
on uneven or unstable surfaces, where they may
fall and cause damage, affects the sound quality.
Connecting your speakers to the receiver
Speaker configuration
The following table indicates the channels you
should use depending on the number of speakers
that you have. For 5.1-channel surround-sound
playback, you need five speakers and a powered
subwoofer.
No matter how many speakers you use, a powered
subwoofer is recommended for a really powerful
and solid bass.
To get the best from your surround sound system,
you need to set the speaker settings.
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.
• 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 receiver.
• Make sure the metal core of the wire does not
contact the receiver’s rear panel. Doing so may
damage the receiver.
• Don’t connect more than one cable to each
speaker terminal. Doing so may damage the
receiver.
• Don’t connect one speaker to several terminals.
To connect the speaker cables:
1 Strip 1/2" to 5/8" (12 to 15 mm) of insulation
from the ends of the speaker cables, and twist
the bare wires tightly.
2 Push in on the speaker terminals on the receiver
and insert the speaker wires into the terminals.
The following illustration shows which speaker
should be connected to each pair of terminals.
3 Release the terminals to secure the wire.
To connect the subwoofer:
1 Using a subwoofer RCA cable, connect the AV
receiver's SUBWOOFER PRE OUT jack to an
input on your powered subwoofer, as shown.
