User manual JBL SS88IWS

[. . . ] Installing the SS88IWS near a corner will tend to maximize low-frequency output. Be cautious when installing in a corner, to avoid a "boomy" sound. Also take into consideration any unusual features of the room, such as an alcove, which may tend to create a localized node that may affect bass response in that area of the room. It is generally recommended that the speaker be installed so that the bottom of the speaker is approximately 12" from the floor. [. . . ] Connection Method #1 Use this method when you are using the SS88IWS with your main receiver/amplifier. Connect the main left and right speaker-level outputs on your receiver/amplifier to the Input 1 (for left channel) and Input 2 (for right channel) connectors on the SS88IWS loudspeaker or connection panel. Connect the Output 1 terminals to the corresponding terminals on your front left speaker, and the Output 2 terminals to the corresponding terminals on your front right speaker. You may wish to mount the SS88IWS horizontally to preserve the stereo image of the left and right low frequencies.

NOTE: When using Connection Method #1 with only one SS88IWS, the shorting straps must be removed. If you are using two SS88IWS subwoofers, connect the left speaker outputs on your receiver/amplifier to Input 1 on one subwoofer (or the connections panel on its back box), and the right speaker outputs on your receiver/amplifier to Input 1 on the second subwoofer (or the connections panel on its back box). Then connect Output 1 from the leftchannel subwoofer to the inputs on your main left speaker, and Output 1 from the right-channel subwoofer to the inputs on your main right speaker. When using the SS88IWS in this mono mode, you should not remove the shorting straps. Connection Method #2 Use this method when you are using the SS88IWS with a dedicated subwoofer amplifier. Connect your main receiver/ processor's line-level subwoofer output to the line-level input on your subwoofer amplifier. Connect the speaker terminals on your subwoofer amplifier to either Input 1 or Input 2. If your amplifier has stereo outputs, you may connect one channel to each of Inputs 1 and 2. However, you must remove the shorting straps when using stereo mode. Alternatively, you may connect each channel to a separate SS88IWS. When using only one input on an individual SS88IWS, you should leave the shorting straps in place. NOTE: The built-in network on the SS88IWS is a 2nd-order low-pass filter, crossed over at 100Hz. Although the subwoofer or LFE output on your receiver/ processor may already be crossed over, the SS88IWS's network will not interfere with the higher-order processing that is occurring at the preamp stage. Using the SS88IWSBB Back Box Whichever connection method you choose, if you are installing the SS88IWSBB back box, you will need to connect all of the eight wires coming out of the bottom of the back box to the appropriate terminals on the loudspeaker. The wires are color-coded as follows: INPUT 1 (­): Yellow with black stripe INPUT 1 (+): Solid yellow INPUT 2 (­): White with black stripe INPUT 2 (+): Solid white OUTPUT 1 (­): Orange with black stripe OUTPUT 1 (+): Solid orange OUTPUT 2 (­): Green with black stripe OUTPUT 2 (+): Solid green Connection Method #2, Using One SS88IWS in Mono Mode (Use Shorting Straps) Receiver/Processor Subwoofer Out Amplifier Line-Level Input Speaker-Level Outputs Rear of SS88IWS* + OUT 1 ­ L1 J2 J1 C1 SS88IWS L3 C3 C4 BLK + OUT 2 ­ 6 GRN ­ + BLK + IN 1 ­ + IN 2 ­ L2 C2 L4 ORN Connection Method #2, Using One SS88IWS in Stereo Mode (Remove Shorting Straps) Receiver/Processor Subwoofer or Main Amp Out Amplifier Line-Level Inputs Speaker-Level Outputs Rear of SS88IWS* + OUT 1 ­ Left Left Left J2 J1 L1 C1 SS88IWS L3 C3 C4 BLK + OUT 2 ­ GRE GRE ­ Right Right Right + * Use corresponding inputs on SS88IWSBB connections panel when installed with back box.

INSTALLATION The JBL Performance Specialist in-wall speakers were designed to be easily installed. However, if you are unsure of your ability to properly install these loudspeakers, please contact your dealer or a qualified installer.

If at some later date you wish to remove the grille from the speaker, to avoid scratching the grille or baffle you may unfold a paper clip, insert the straight end through one of the holes in the grille, and gently pull up. Determine the correct speaker location. · Use the cardboard template when cutting the drywall. Although the SS88IWS may be oriented either horizontally or vertically, the installation procedure is the same. At this time, make note of adjustments necessary to square the enclosure into the wall (see Detail C). Centering Bar See Detail C L-Brackets Detail A 4. [. . . ] See your receiver/ processor's owner's manual for further information on correct speaker configuration in Dolby Digital, DTS and other surround sound modes. · 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. · If more than one pair of main speakers is being used, check the minimum-impedance requirements of your receiver/amplifier. 11 SPECIFICATIONS SS88IWS Frequency Response Impedance Sensitivity Crossover Frequency Woofer Plate Size (W x H) Mounting Cutout Size (W x H) Mounting Depth Weight per Speaker 30Hz ­ 100Hz (­6dB) 8 Ohms nominal per woofer 94dB (2. 83V/1m), both woofers driven 100Hz, 2nd order Dual 8" polymer-coated aluminum cones w/rubber surrounds 11-7/16" x 20-7/16" (290mm x 518mm) 10" x 18-5/16" (254mm x 465mm) 3-7/8" (98mm) 17 lb (7. 7kg) Maximum Recommended Amplifier Power 250 Watts per channel All features and specifications are subject to change without notice.
