User manual JBL HTI88

[. . . ] Installing the HTI88 near a corner will tend to maximize lowfrequency 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. [. . . ] 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 HTI88 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 correspon- ding terminals on your front right speaker. You may wish to mount the HTI88 horizontally to preserve the stereo image of the left and right low frequencies. The HTI88's onboard crossover feeds the low-passed signal (2nd order at 100Hz) to the HTI88 subwoofers, and Connection Method #1, Using Two HTI88 Loudspeakers (Use Shorting Straps) Receiver/Amplifier Speaker Outputs Left Right ­ Rear of Left HTI88 + OUT 1 ­ GRN BLK + ­ + Rear of Right HTI88 + OUT 1 ­ C2 C4 BLK GRN BLK + IN 1 ­ + IN 1 ­ L1 J2 J1 L2 C1 C2 J2 J1 L1 L2 C1 HTi88s L3 C3 C4 HTi88s L3 C3 + OUT 2 ­ BLK ORN ORN Front Left Speaker Front Right Speaker ­ + ­ + Connection Method #1, Using Two HTI88 Loudspeakers With Back Boxes (Use Shorting Straps) Receiver/Amplifier Speaker Outputs Left Right ­ + ­ + Connections Panel of Right HTI88 Back Box YEL/BLK YEL WHT/BLK WHT ORG/BLK ORG GRE/BLK GRE Connections Panel of Left HTI88 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 Front Left Speaker Front Right Speaker ­ + ­ + 5 + OUT 2 ­ ­ + OUTPUT 2 L4 L4 + IN 2 ­ + IN 2 ­ the high-passed signal to the speaker-level outputs for connection to the satellite speakers. 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 (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 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. NOTE: The built-in network on the HTI88 is a 2nd-order lowpass filter, crossed over at 100Hz. Although the subwoofer or LFE output on your receiver/processor may already be crossed over, the HTI88's network will not interfere with the higherorder processing that is occurring at the preamp stage. Using the HTI88BB Back Box Whichever connection method you choose, if you are installing 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 colorcoded 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 HTI88 in Mono Mode (Use Shorting Straps) Receiver/Processor Subwoofer Out Amplifier Line-Level Input Speaker-Level Outputs Rear of HTI88** + OUT 1 ­ L1 J2 J1 C1 HTi88s L3 C3 C4 BLK + OUT 2 ­ 6 GRN ­ + BLK + IN 1 ­ + IN 2 ­ L2 C2 L4 ORN Connection Method #2, Using One HTI88 in Stereo Mode (Remove Shorting Straps) Receiver/Processor Subwoofer or Main Amp Out Amplifier Line-Level Inputs Speaker-Level Outputs Rear of HTI88** + OUT 1 ­ Left Left Left J2 J1 L1 C1 HTi88s L3 C3 C4 BLK + OUT 2 ­ GRE GRE ­ Right Right Right + ** Use corresponding inputs on HTI88BB connections panel when installed with back box.

INSTALLATION Tools Needed The JBL HTI Series in-wall speakers were designed to be easily installed. However, if you are unsure of your ability to properly install these loud- Pencil speakers, 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. [. . . ] 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 HTI88 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.
