Connecting Your Speakers
For the best surround-sound experience, you should con-
nect five speakers and a powered subwoofer.
The following table shows which channels you should
use based on the number of speakers that you have.
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 specify the distance between the listener
and each individual speaker so that the sound from each
speaker arrives at the listener’s ears at the same time (see
page 52). In addition, you should set the level of each
individual speaker to achieve an equal balance (see
page 52.)
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:
• You can 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 lev-
els 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.
