Connecting up
Connecting the speakers
The receiver will work with just two stereo speakers (the front speakers in the diagram) but using
at least five speakers is recommended, and a complete setup is best for surround sound.
To achieve the comfortable surround sound, install your speakers as shown below.
7.1 channel surorund system:
L
– Front Left
C
– Center
R
– Front Right
SL
– Surround Left
SR
– Surround Right
SBL
– Surround back Left
SBR
– Surround back Right
SW
– Subwoofer
Note
• There are also other speaker connection
patterns (top middle, front height, front
wide, etc.). For details, see “Connecting
your equipment” of the operating
instructions.
Connecting the speaker cables
Make sure you connect the speaker on
the right to the right (
