Connecting the Amplifier
Before connecting the speakers, place them correctly by 
consulting the instruction manuals that came with them. 
For surround playback, the configuration and placement 
of your speakers are very important.
Please note that connecting speakers with a low power 
input rating does not produce large sound volumes. For 
those speakers, large sound volumes causing excessive 
input level may damage the speakers.
Note:
Once you’ve completed speaker connections, you must 
turn on the AV controller or control amplifier and con-
figure the output channels.
Attaching the Speaker Labels
The amplifier’s positive (+) speaker terminals are all red 
(the negative (–) speaker terminals are all black).
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 above table. 
Then all you need to do is to match the color of each 
label to the corresponding speaker terminal.
(North American models)
• If you are using banana plugs, tighten the speaker ter-
minal 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 
between 4 and 16 ohms. If the impedance 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 “4ohms” (see page 10). If you use speakers with a 
lower impedance, and use the amplifier at high vol-
ume levels for a long period of time, the built-in pro-
tection 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 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.
• If you use 4 or 5 speakers, connect each of the two 
surround speakers to the SURR L/R terminals. Do not 
connect them to the SURR BACK L/R or FRONT 
HIGH/WIDE L/R terminals.
• Be careful not to short the positive and negative wires. 
Doing so may damage the amplifier.
• Make sure the metal core of the wire does not have 
contact with the amplifier’s rear panel. Doing so may 
damage the amplifier.
• Don’t connect more than one cable to each speaker 
terminal. Doing so may damage the amplifier.
• Don’t connect one speaker to several terminals.
