English Setting Up Check the connections Check to be sure all connections are made positive to positive (+ to +) and negative to negative (- to -). Make sure that no loose strands of wire touch across terminals. Loose wire strands could short circuit, which can result in electrical shock or damage. Tighten any loose connections before you plug in the receiver or amplifier and turn it on. Figure 3 Completed connections + + - - Amplifier or receiver - + -+ Test the speakers To make sure your speakers operate correctly: 1. Set your receiver or amplifier to MONO (monophonic) and turn it on. 2. Set the balance control to normal (center position). 3. Place the speakers less than 6 inches (15 cm) apart, facing each other. 4. Play some deep bass passages of music through the speaker. The sound should seem to come from a point between the two speakers. The bass should be full and natural. If it is not, your connections may be out of phase. To make them match connections to the amplifier, try reversing the + and - connections on the back of one speaker. Then repeat steps 1 - 4. 5
