User manual JBL D44000WXA PARAGON

[. . . ] These recommendations are for the optimum placement of the loudspeakers. The front speakers should be placed the same distance from each other as they are from the listening position. They should and, ideally, should face each other and be at a level higher than the listeners' ears. If that is not possible, they may be placed in a wall behind the listening position, facing forward. [. . . ] If that is not possible, they may be placed in a wall behind the listening position, facing forward. The rear wall is the required mounting position for the surround back speakers in 6. 1- and 7. 1-channel system. They should provide a diffuse, ambient sound accompanying the main program material heard in the front speakers. In Dolby* Digital and DTS® systems, aim the tweeters toward the listening position at ear-level height. 3 SPEAKER CONNECTIONS English CONNECTION TIPS The wires for both speakers should be the same length. If one speaker is placed closer to the amplifier than the other, hide the excess wire behind the wall. Speakers and electronics terminals have corresponding (+) and (­) terminals. Most manufacturers of speakers and electronics, including JBL, use red to denote the (+) terminal and black for the (­) terminal. 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. With the advent of multichannel surround-sound systems, connecting all of the speakers in your system with the correct polarity remains equally important in order to preserve the proper ambience and directionality of the program material. LEFT RIGHT LEFT RIGHT Front or Rear Speaker Outputs WIRE LENGTH RECOMMENDED SIZE Up to 20 ft. Before painting, install the paint shield (in the assembly kit) securely into the recess in the baffle. This will protect the speaker components and baffle from paint residue. Note: Gently remove the acoustical foam blanket from the grille before painting. Reattach the blanket after the paint has dried. TROUBLESHOOTING IF THERE IS NO SOUND FROM ANY OF THE SPEAKERS: · Check that receiver/amplifier is on and a source is playing. · Check all wires and connections between receiver/amplifier and speakers. · Review proper operation of your receiver/amplifier. IF THERE IS NO SOUND COMING FROM ONE SPEAKER: In multichannel applications, make sure that your receiver or processor has been configured to enable all channels that you are using. IF THERE IS LOW (OR NO) BASS OUTPUT: See your receiver/processor's owner's manual for futher information on correct speaker configuration in Dolby Digital, DTS and other surround-sound modes. IF THE SYSTEM PLAYS AT LOW VOLUMES BUT SHUTS OFF AS VOLUME IS INCREASED: · Make sure the connections to the left and right "Speaker Inputs" have the correct polarity (+ and ­). · In Dolby Digital or DTS modes, make sure your receiver/processor is correctly configured. When using a subwoofer, make sure the subwoofer output of the receiver/ processor has been enabled. If no subwoofer is being used, make sure the left and right front and rear speakers have been config-ured as "LARGE. " · Check all wires and connections between receiver/amplifier and speakers. · If more than one pair of main speakers is being used, check the minimum-impedance requirements of your receiver/ amplifier. · Check the "Balance" control on your receiver/amplifier.
