Connecting Your Speakers
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.
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.
Note:
When speaker set B is turned on, speaker set A is reduced
to 5.1-channel playback.

1 On the AV receiver, unscrew the terminal. Fully
insert the bare wires. Make sure that the bare wire
is touching the inside of the pole. Screw the termi-
nal tight.
2 On the speakers, loosen the binding posts.
Insert the speaker wires
into the binding posts as
shown, then tighten the
binding posts.
3 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
separately)
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.
