the negative (-) terminal of the unit and the speaker, and
the other is for the positive (+) terminal. If the wires are
colored to prevent confusion, connect the black wire to
the negative and the other wire to the positive terminal.

the ends of the speaker cable and twist the bare wires of
the cable firmly together.

Insert the bare wires of the cable into the gap on the side
(upper right or bottom left) of the terminal.

Connecting speakers
Caution
• Remove the unit’s power cable from an AC wall outlet and turn
off the subwoofer before connecting the speakers.
• Ensure that the core wires of the speaker cable do not touch
one another or come into contact with the unit’s metal parts.
Doing so may damage the unit or the speakers. If the speaker
cables short circuit, “Check SP Wires” will appear on the front
display when the unit is turned on.
