User manual JBL SS88IWSBB

[. . . ] 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. Note that installing the speaker within the SS88IWSBB back box as shown in the illustration to the left will achieve the recommended height. [. . . ] Depending on whether you are using a dedicated subwoofer amplifier or your main receiver/amplifier to power the SS88IWS, select one of the two connection methods that follow. 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 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. 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's connections panel, and the right speaker outputs on your receiver/amplifier to Input 1 on the second subwoofer's connections panel. Then connect Output 1 from the left-channel 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. Using the SS88IWSBB Back Box Whichever connection method you choose to install 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 Connection Method #1, Using Two SS88IWS Loudspeakers With Back Boxes (Use Shorting Straps) Receiver/Amplifier Speaker Outputs Left Right OUTPUT 1 (­): Orange with black stripe OUTPUT 1 (+): Solid orange OUTPUT 2 (­): Green with black stripe OUTPUT 2 (+): Solid green ­ + ­ + Connections Panel of Right SS88IWSBB Back Box YEL/BLK YEL WHT/BLK WHT ORG/BLK ORG GRE/BLK GRE Connections Panel of Left SS88IWSBB Back Box YEL/BLK YEL WHT/BLK WHT ORG/BLK ORG GRE/BLK GRE ­ + INPUT 1 ­ + INPUT 2 ­ + OUTPUT 1 ­ + OUTPUT 2 ­ + INPUT 1 ­ + INPUT 2 ­ + OUTPUT 1 ­ + OUTPUT 2 Front Left Speaker Front Right Speaker Connection Method #1, Using One SS88IWS With Back Box (Remove Shorting Straps) Receiver/Amplifier Speaker Outputs Left Right ­ + ­ + ­ Connection Method #2, Using Two SS88IWS Loudspeakers With Back Boxes (Use Shorting Straps) YEL/BLK YEL + ­ + WHT/BLK WHT ORG/BLK ORG GRE/BLK GRE Receiver/Processor Subwoofer or Main Amp Out Amplifier Line-Level Inputs Speaker-Level Outputs YEL/BLK YEL Left SS88IWSBB Back Box WHT/BLK WHT ORG/BLK ORG GRE/BLK GRE ­ + INPUT 1 ­ + INPUT 2 ­ + OUTPUT 1 ­ + OUTPUT 2 ­ Left Left + ­ + INPUT 1 ­ + INPUT 2 ­ + OUTPUT 1 ­ + OUTPUT 2 Connections Panel of SS88IWSBB Back Box Front Left Speaker Front Right Speaker Left Right SS88IWSBB Back Box ­ Right Right Right + YEL/BLK YEL WHT/BLK WHT ORG/BLK ORG GRE/BLK GRE ­ + INPUT 1 ­ + INPUT 2 ­ + OUTPUT 1 ­ + OUTPUT 2 ­ + ­ + INSTALLATION Although the JBL Performance Specialist Series in-wall speakers were designed to be easily installed in existing construction applications, it is recommended that installation of the SS88IWSBB back box in new construction be reserved for professionals. See the manual for the SS88IWS subwoofer for instructions on installing the speaker in existing construction without using the back box. The SS88IWSBB back box is an optional installation accessory for the SS88IWS in-wall subwoofer. [. . . ] Screw the L-brackets into the studs, using the eight wood screws. Remove the wood centering bars and replace the flat-head screws into the holes left over (the holes left in the cabinet face underneath the bars are also counterbored to accept the flat-head screws). The enclosure is now installed and ready for the wallboard to be installed over it. [. . . ]
