CONNECTIONS TO THE RECEIVER CONNECTIONS Check to make sure that the power has been turned off before making connections. Connect the (+) terminal of the amplifier to the (+) terminal of the speaker. Connect the (-) terminal of the amplifier to the (-) terminal of the speaker. Reversing polarity (+/-) will result in unnatural sound reproduction. PROCEDURE For connections, keep the speaker cords as short as possible. Do not bundle or roll up the excess part of the cords. If the connections are faulty, no sound will be heard from the speakers. Make sure that the + and - polarity markings of the speaker cords are observed and set correctly. If these cords are reversed, the sound will be unnatural and lack bass. How to Connect: 1 Press and hold the terminal's tab. 2 Insert the bare wire into the terminal hole. [Remove approx. 3/8" (10 mm) insulation from the speaker cords.] Good 10 mm No Good Make sure the lead portions of the speaker cable are not exposed outside of the connectors. 3 Release your finger from the tab to allow it to lock securely on the bare wire end. 4 Test the firmness of the connection by pulling lightly on the cord at the terminal. Note Do not let the bare speaker wires touch each other as this could damage the speaker, the amplifier, or both. 6
