Right speaker
Connecting to this unit's OUTPUT/INPUT terminals
For connections, cut the speaker wires as short as possible. If
the connections are faulty, no sound will be heard from the
speakers. Make sure that the polarity of the speaker wires is
correct, that is, + and – markings are observed. If these wires
are reversed, the sound will be unnatural and will lack bass.
Do not let the bare speaker wires touch each other and do
not let them touch the metal parts of this unit as this could
damage this unit, your amplifier and/or speakers.
How to Connect:
Red: positive (+)
Black: negative (–)
