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 sub- woofers, connect the left speaker outputs on your receiver/ampli- fier to Input 1 on one subwoofer (or the connections panel on its back box), and the right speaker outputs on your receiver/ampli- fier to Input 1 on the second subwoofer (or the connections panel on its back box). 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 dedi- cated 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 low- pass filter, crossed over at 100Hz. This filter is always active. Although the subwoofer or LFE output on your receiver/proces- sor may already be crossed over, the HTI88’s network will

not interfere with the higher- order processing that is occur- ring 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 appropri- ate terminals on the loud- speaker. 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
