Connecting the AV Receiver
Speaker Configuration
For the best surround-sound experience, you should
connect five speakers and a powered subwoofer.
The following table shows which channels you should
use based on the number of speakers you have.
No matter how many speakers you use, a powered
subwoofer is recommended for a powerful and solid
bass.
To get the best from your surround-sound system, you
must set the speaker settings. You can do this
automatically (see page 33) or manually (see page 54).
Connecting a Powered Subwoofer
Using a suitable cable, connect the AV receiver’s PRE
OUT: SUBWOOFER to the input on your powered
subwoofer. If your subwoofer is unpowered and you’re
using an external amplifier, connect the PRE OUT:
SUBWOOFER to the amp’s input.
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 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.
For North American model
• If you are using banana plugs, tighten the speaker
terminal before inserting the banana plug.
• Do not insert the speaker code directly into the center
hole of the speaker terminal.
Speaker Connection Precautions
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
levels 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. Connect
positive (+) terminals to only positive (+) terminals,
and negative (–) terminals to only 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.
• Don’t connect more than one cable to each speaker
terminal. Doing so may damage the AV receiver.
• Don’t connect a speaker to several terminals.
