User manual JBL HTI88BB

[. . . ] 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. [. . . ] 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 HTI88, the shorting straps must be removed. If you are using two HTI88 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 HTI88 in this mono mode, you should not remove the shorting straps. Connection Method #2 Use this method when you are using the HTI88 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 HTI88. When using only one input on an individual HTI88, you should leave the shorting bars in place. Using the HTI88BB Back Box Whichever connection method you choose, to install the HTI88BB 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 HTI88 Loudspeakers With Back Boxes (Use Shorting Straps) Receiver/Amplifier Speaker Outputs Left Right OUTPUT 1 (­): Orange with black stripe OUTPUT 1 (+): Solid orange ­ + ­ + Connections Panel of Right HTI88BB Back Box YEL/BLK YEL WHT/BLK WHT ORG/BLK ORG GRE/BLK GRE OUTPUT 2 (­): Green with black stripe OUTPUT 2 (+): Solid green Connections Panel of Left HTI88BB 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 HTI88 With Back Box (Remove Shorting Straps) Receiver/Amplifier Speaker Outputs Left Right ­ Connection Method #2, Using Two HTI88 Loudspeakers With Back Boxes (Use Shorting Straps) Receiver/Processor Subwoofer or Main Amp Out + ­ + Amplifier Line-Level Inputs Speaker-Level Outputs YEL/BLK YEL Left HTI88BB Back Box WHT/BLK WHT ORG/BLK ORG GRE/BLK GRE YEL/BLK YEL WHT/BLK WHT ORG/BLK ORG GRE/BLK GRE ­ Left Left + ­ + INPUT 1 ­ + INPUT 2 ­ + OUTPUT 1 ­ + OUTPUT 2 ­ + INPUT 1 ­ + INPUT 2 ­ + OUTPUT 1 ­ + OUTPUT 2 Left Right HTI88BB Back Box Connections Panel of HTI88BB Back Box Front Left Speaker Front Right Speaker ­ 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 HTI Series inwall speakers were designed to be easily installed in existing construction applications, it is recommended that installation of the HTI88BB back box in new construction be reserved for professionals. See the manual for the HTI88 subwoofer for instructions on installing the speaker in existing construction without using the back box. [. . . ] The enclosure is now installed and ready for the wallboard to be installed over it. Make the connections from your receiver/amplifier to the HTI88 back box connections panel, and to any other speakers as appropriate for your system, following the instructions on the previous page.
