Connecting Your Speakers
—Continued
Read the following before connecting your speakers:
• You can connect speakers with an impedance of
between 8 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 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 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.
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.
The supplied speaker terminal tool makes it easy to
tighten and loosen the speaker terminals. (In Europe,
using banana plugs to connect speakers to an audio
amplifier is prohibited.)
