Connecting Speakers

Speaker Connection Precautions

Read the following before connecting your speakers:
• You can connect speakers with an impedance of
8 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.
• 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.

Connecting Speaker Set A

The AV receiver's positive (+) speaker terminals and
speaker's positive (+) terminals are color-coded for ease
of identification. (The negative (–) speaker terminals are
all black.) Match the color of each cable to the corre-
sponding speaker terminal.

insert the bare wires. Make sure that the bare wire
is touching the inside of the pole. Screw the termi-
nal tight.

On the speakers, while pressing
the terminal lever, insert the
wire into the hole, and then
release the lever.

Using the supplied RCA cable, connect the AV
receiver's SUBWOOFER PRE OUT to LINE
INPUT on the subwoofer.
Make sure the cable is plugged all the way.
Connecting Speaker Set B (sold

1
Strip 3/8" (10 mm) of insu-
lation from the ends of the
speaker cables, and twist
the bare wires tightly, as
shown.
2
While pressing the lever, insert
the wire into the hole, and then
release the lever.
Make sure that the terminals are
gripping the bare wires, not the
insulation.
