Speaker Placement JBL500, JBL800 JBL900 JBL Center 0-2 ft. two. Speaker Connections Connection Tips Speakers and electronics terminals have corresponding (+) and (­) terminals. It is important to connect both speakers identically: (+) on the speaker to (+) on the amplifier and (­) on the speaker to (­) on the amplifier. Wiring "out of phase" results in thin sound, weak bass and a poor stereo image. RIGHT LEFT ­ + ­ + ­+ ­+ Speaker Outputs Troubleshooting If there is no sound from any of the speakers, check the following: · Receiver/amplifier is on and a source is playing. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is low bass output, check the following: · Make sure the polarities (+ and ­) of the left and right "Speaker Inputs" are connected properly. If there is no sound from the center speaker, check the following: · Make sure that your receiver's Center Channel Mode is in the "normal" or "wide" position. If it is in the "phantom" position, the center speaker will not play. · Check all connections between processor/amplifier and the center speaker.
