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

 

. 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.

 

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.

 

On the speakers, loosen the binding posts. 
Insert the speaker wires 
into the binding posts as 
shown, then tighten the 
binding posts.

 

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.

 

Strip 3/8" (10 mm) of insu-
lation from the ends of the 
speaker cables, and twist 
the bare wires tightly, as 
shown.

 

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.
