[. . . ] They should provide a diffuse, ambient sound accompanying the main program material heard in the FRONT SPEAKERS WALL 400­ 600 front speakers. In Dolby® Digital and DTS® systems, aim the tweeters toward the listening position at ear-level height. MODELS R82, IS6, IS8 AS REAR SPEAKERS 5 ­ 6 ft. WALL WALL WALL WALL MODEL IS6DT IN-CEILING IS6DT speaker centrally in the ceiling for best stereo imaging, swiveling the tweeters so that one points toward the left and the other toward the right of the listening position, aimed at earlevel height. The IS6DT may also be used to play the left and right surround channels in a 5. 1-channel home theater system, in which case it should be mounted in the ceiling slightly behind the listening position, centered from left to right and with the tweeters pointing toward the left and right of the listening position, aimed at ear-level height. For 7. 1-channel systems where it is desired to use two IS6DT speakers, one to play both the left surround and surround back channels and the other to play both the right surround and surround back channels, mount each IS6DT speaker in the ceiling, slightly behind the listening position. [. . . ] Place one closer to the left side of the room and the other closer to the right side. Aim the tweeters away from each other, toward the front and rear of the room. The IS6DT has the capability of playing two channels through one speaker, thanks to its dualtweeter/dual-voice-coil construction. Since the tweeters are close together, in general they should be aimed away from each other for best coverage. For two-channel (stereo) applications, e. g. , as a single speaker in a remote room of a distributed audio system, install the 3 SPEAKER CONNECTIONS 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 For model IS6DT, the terminals for both the left and right channels will systems, connecting all of the be on the same loudspeaker. The locking tabs will swivel into place and secure the unit to the rear surface of the drywall. Performance Integrator loudspeakers feature unique swivel mounts for the tweeters, enabling you to aim the very directional high frequencies toward the listening position, at ear-level height. Before installing the speaker grille, gently press on the outer edge of the tweeter mount to adjust the position of the tweeter. The tweeter will not swivel more than 15 degrees in any direction; do not attempt to force it to move 6 any further. Optimum imaging will be obtained by aiming the tweeters to the left and right of the listening position, at ear-level height, if your application permits. Replace the metal grille. NEW CONSTRUCTION You will need to purchase the correct rough-in frame kit for your model: SPEAKER MODEL ROUGH-IN FRAME KIT R82 IS6 IS6C, IS6DT IS8 IS8C RIF5 RIF6 RIF6C (pair pack)/RIF6CS (single pack) RIF8 RIF8C Detailed installation instructions are supplied with the rough-in kit. PAINTING THE SPEAKER FRAME AND GRILLE Performance Integrator loudspeakers can be painted to match any décor. If you wish to change their color, the satin finish on the grille and frame will function as a primer coat. Before painting, install the paint shield (inner section of template 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: sure none of the speaker wires are frayed, cut, punctured or touching each other. IF THERE IS LOW (OR NO) BASS OUTPUT: · Check that receiver/amplifier is on and a source is playing. · Check all wires and connections between receiver/amplifier and speakers. [. . . ] · Check all wires and connections between receiver/amplifier and speakers. Make sure none of the speaker wires are frayed, cut, punctured or touching each other. · Review proper operation of your receiver/amplifier. IF THERE IS NO SOUND COMING FROM ONE SPEAKER: 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.
