User manual JBL SCS SAT 300 (220-240V)

[. . . ] Two of the surround speakers should be placed slightly behind the listening position 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 on a wall behind the listening position, facing forward. The rear wall is also the required placement for the surround back speakers in a 7. 1-channel system. The surround back speaker in a 6. 1-channel system should be placed on the wall behind the listening position, facing the center channel speaker. [. . . ] Refer to the exploded drawing for the proper orientation of these three parts. Step 5: Tighten the Metal Nut ¡ with the star washer side between the Metal Nut ¡ and the back of the Satellite Speaker ¶, using large needle-nose pliers until it is firmly seated against the back of the Speaker ¶ and has locked the Ball and Shaft £ and the Speaker ¶ together. Note that once the Metal Nut ¡ is fully tightened, it may embed some marks on the back of the Satellite Speaker ¶. However, these marks will be covered by the Metal Nut ¡ Step 6: Mount the Attachment Plate ¢ into a wood stud on the wall, using four #10 pan-head wood screws at least one inch long (not supplied) ·. Make sure that all four screws are driven 7 6 1 2 3 4 5 8 Step 4: Screw the Ball and Shaft £ into the Threaded Insert § on the back of the Satellite Speaker ¶ until it is fully seated in the Threaded Insert §, but do not tighten as you might dislodge the Threaded Insert §. Such damage would not be covered under the warranty. into the stud and not into drywall. If the bracket needs to be mounted in drywall, the customer is responsible for selecting and using appropriate wall-anchors and screws. Important Note: The Metal Nut ¡ must be fully tightened against the Satellite Speaker ¶ as described in Step 5 before beginning Step 7 in order to avoid damage to the Threaded Insert §. Such damage would not be covered under the warranty. Step 7: Holding the Satellite Speaker ¶ with both hands, reinsert the ball portion of the Ball and Shaft £ into the Attachment Plate ¢. Step 8: Hand-tighten the Molded Nut TM while positioning the speaker for the desired orientation. If the Molded Nut TM is difficult to tighten by hand, insert the Metal Bar into one of the holes in the outer edge of the Molded Nut TM and use the bar as a lever. The swiveling ball enables you to aim the speaker to one side or the other, or to tilt it up or down. Although stereo imaging may be improved by aiming the front speakers toward the listening position, especially for music selections, the surround speakers are intended to provide a diffuse, ambient sound that is best achieved by aiming the speakers straight out from the wall. Aiming the surround speakers toward the listening position may ruin the intended effect by calling too much attention to the information in those channels. Step 9: Once the speaker's orientation has been finalized, insert the Metal Bar into one of the holes in the outer edge of the Molded Nut TM and tighten the Molded Nut TM securely. Keep the Metal Bar in a safe place in the event that you decide to adjust the speaker's orientation in the future. SPEAKER CONNECTIONS CONNECTION TIPS JBL, use red to denote the (+) terminal and black to denote the (­) terminal. The (+) lead of the speaker wire is noted with a stripe. 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. Separate and strip the ends of the speaker wire as shown. The wires supplied with the system may already be stripped and tinned for easy insertion into the speaker terminals. You may need to separate the two conductors further in order to thread them through the shelf stand or floor stand adaptor. [. . . ] Make sure none of the speaker wires are frayed, cut or punctured, or touching each other. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is low (or no) bass output: · Make sure the connections to the left and right "Speaker Inputs" have the correct polarity (+ and ­). · If your system includes a subwoofer, check its operation and the configuration of your receiver or processor.
