Speaker connections
(SC-F391, SC-C391, SC-R391)
• Connect the input terminals on the rear panel of the speaker with
the speaker output terminals on the amplifi er, using the included
speaker cables.
• Labels on the back of each speaker are marked “FR”, “FL”, “C”, “SR”,
“SL”. Connect each speaker to the following amplifi er terminals. Be
sure to connect each speaker with correct polarity (+, –).
• FR To the amplifi er’s front-right speaker terminal.
• FL To the amplifi er’s front-left speaker terminal
• C To the amplifi er’s center speaker terminal
• SR To the amplifi er’s surround-right speaker terminal.
• SL To the amplifi er’s surround-left speaker terminal.
Amplifi ers have various speaker output terminals.
Check the owner’s manual of the amplifi er you are using for details.
NOTE
• Be sure to turn the amplifi er’s power off before connecting the
speakers to the amplifi er.
• If the polarities are inverted, the phase may be off and the sound
may have no bass component, making it seem unnatural. Be sure
to connect the polarities properly.

1
Peel off the sheath from the tip of
the speaker cable, then fi rmly twist
the wires by hand so that they do not
stick out and cause short-circuits.
2
Press and lower the lever, and insert
the cable’s core wire into the hole.
3
Release the lever.
Gently pull on the speaker cable to
check that it is fi rmly connected.
Once connections are completed, pull gently on the speaker cables
to check that they are securely connected.
NOTE
Do not let the core wires of two speaker cables touch each other.
Doing so will short-circuit the amplifi er circuitry and damage the
amplifi er.
