Connecting Speakers
—Continued
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.

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