Connecting Your Speakers
For the best surround-sound experience, you should con-
nect seven speakers and a powered subwoofer.
The following table shows which channels you should
use based on the number of speakers that you have.
*If you’re using only one surround back speaker, connect it to
the left (L) SURROUND BACK SPEAKERS terminals.
No matter how many speakers you use, a powered sub-
woofer is recommended for a really powerful and solid
bass.
Before using the AV receiver, you must specify which
speakers are connected and their sizes (see page 34).
To get the very best from your surround-sound system,
you should also set the advanced speaker settings (see
page 55.)
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.
Read the following before connecting your speakers:
•
North American models: 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 acti-
vated.
• 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 34). 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 acti-
vated.
• 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 a speaker to several terminals.
