JBL Consumer Products THE PERFORMANCE SYSTEM The Performance System is an extremely high-performance speaker system intended for uses ranging from premium two-channel stereo all the way to 5. 1, 6. 1 or 7. 1 multi-channel home-theater applications. [. . . ] The "Reverse" position may be used when the JBL830 and PT800 are separated, and due to wave cancellation, bass response is improved in this position. "Reverse" may also be selected when different amplifiers are used that have different polarity configurations.

" ® NRTL/C CSA 22-2 UL 1492 PN 336609-001 8 LFE Level Control ­ This control only affects the signal sent to the LFE input. Adjust the LFE level by starting with the level controls on both JBL830 modules in the Minimum position. With 5. 1, 6. 1 or 7. 1 source material playing, advance the LFE Level controls on both JBL830s slowly until the desired amount of effects channel is present. The normal position for this control is full clockwise, with LFE adjustments being made via the level adjustments on your processor. We have provided this control because the LFE output level of AV receivers and processors can vary from manufacturer to manufacturer. If you are using the third or fourth configurations, where the main speakers are configured as "Small" and all bass information is being sent to the LFE inputs of the JBL830s, the LFE Level control will operate on all low- frequency information, and not just for the . 1 channel effects. § LFE/Subwoofer Input ­ This jack accepts either an LFE or line-level output from the receiver or processor. ¶ System Input ­ These binding posts accept a fullrange, amplified (speakerlevel) output from the receiver or amplifier. This input should be used whenever the JBL830 and PT800 modules will be stacked and the internal crossover used to form an integrated floorstanding speaker system. This input should be used in that configuration even if the LFE input will also be used. Remove the JBL logo plate from the mounting plate on top of the JBL830 by gently prying it upwards. This will expose the binding post output terminals that will provide the signal for the PT800 module. It is easiest to connect the gold jumper bars between the terminals on the top of the JBL830 and the terminals on the rear of the PT800 by completely unscrewing the binding post collars first. Insert the closed loop at one end of the jumper bar over the JBL830 output terminal, and insert the open end of the bar around the PT800's input. Screw the collars back onto their respective posts. 10 Left Tower Right Tower ­ + Center ­ + ­ ­ + + ­ + ­ ­ + + Left Sub Right Sub Receiver ­ + ­ + ­ + ­ + ­ + Left Surround Right Surround ­ + ­ + Note: You may, if desired, use stacked JBL830 and PT800 modules in the surround speaker positions. These should be wired the same way as shown above for the front speakers. If you choose this configuration, change the setting on your receiver/processor for the rear channels from "Small" to "Large". 11 Stacked, With LFE and Speaker-Level Inputs to JBL830 and Internal High-Pass Signal Output to PT800 Use this installation method with the PT800 and JBL830 stacked. By using the JBL830's internal crossover to process the full range output of your receiver or amplifier, the Performance speakers can behave as a single full-range system and produce the highest quality of sound reproduction that makes the best use of each transducer component of each module. In addition, the LFE (low-frequency effects) channel provided by some digital sources can be mixed in with the low-frequency signal to provide effects that add excitement and realism to movie soundtracks, musical performances or other materials. Do not use the JBL830's internal crossover and speaker-level outputs unless the JBL830 and PT800 are stacked. If the PT800 is placed separately ­ on the wall, on a shelf or on a stand ­ you must use your receiver or processor's crossover, which should be set to 80Hz. [. . . ] · Check all wires and connections between receiver/ amplifier and speakers. Make sure none of the speaker wires are frayed, cut or punctured. · Review proper operation of your receiver/amplifier. If there is no sound coming from one speaker: · Check the "Balance" control on your receiver/amplifier. [. . . ]
