Connect each speaker to the following amplifier terminals. Besure to connect each speaker with correct polarity (+, –).• FR To the amplifier’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 amplifier’s surround-right speaker terminal.• SL To the amplifier’s surround-left speaker terminal.Amplifiers have various speaker output terminals.Check the owner’s manual of the amplifier you are using for details.NOTE• Be sure to turn the amplifi er’s power off before connecting thespeakers to the amplifier.• If the polarities are inverted, the phase may be off and the soundmay have no bass component, making it seem unnatural. Be sureto connect the polarities properly.ConnectionsConnecting the speaker cablesBlack : “–” (negative) Red : “+” (positive)Black withwhite line cableLeverBlack cable1 Peel off the sheath from the tip ofthe speaker cable, then firmly twistthe wires by hand so that they do notstick out and cause short-circuits.2 Press and lower the lever, and insertthe cable’s core wire into the hole.3 Release the lever.Gently pull on the speaker cable tocheck that it is firmly connected.Once connections are completed, pull gently on the speaker cablesto check that they are securely connected.NOTEDo not let the core wires of two speaker cables touch each other.Doing so will short-circuit the amplifier circuitry and damage theamplifier.Getting started Connections
