® ® Receiver or Amplifier Figure 3 Check the connections Check the speaker and receiver or amplifier connections carefully. Make sure no loose strands of wire touch across terminals. This could create short circuits that can damage an amplifier or receiver. Tighten any loose connections before you plug in the receiver or amplifier. Test the connections To make sure your speakers operate correctly: 1. Set your receiver or amplifier for MONO (monophonic) and turn it on. Set the balance control to normal (centered). 2. Place the speakers less than 6 inches (15 cm) apart, facing each other. 3. Play some deep bass passages of music through the speakers. The sound should seem to come from a point between the two speakers. The bass should be full and natural. If not, your connections may be out of phase. Reverse the connections on the back of one speaker. Then repeat steps 1 - 3. 7
