SPEAKER CONNECTIONS

Connection Tips

Speakers and electronics have corresponding (+) and (–) termi- nals. Most manufacturers of speakers and electronics, including JBL, use red to denote the (+) terminal and black for the (–) terminal. It is important to connect both speakers identically: (+) on the speaker to (+) on the amplifier and (–) on the speaker to (–) on the amplifier. Wiring “out of phase” results in thin sound, weak bass and a poor stereo image. With the advent of multi- channel surround sound systems, connecting all of the

speakers in your system with the correct polarity remains equally important in order to preserve the proper ambience and directionality of the program material.

If two HTI88 subwoofers are used, the wires for both speak- ers should be the same length. If one speaker is placed closer to the amplifier than the other, hide the excess wire behind the wall. If bass response seems low, there may be a phase problem, with the sound waves from the two sub- woofers canceling each other out. If bass response seems low, try inverting the polarity on one subwoofer – i.e., con- nect the (+) terminal on the amplifier to the (–) terminal on the speaker, and the (–) termi- nal on the amplifier to the (+) terminal on the speaker.

To use the spring-clip-type ter- minals on the HTI88 loudspeaker, press the colored tab and insert the bare end of the wire into the hole. Release the tab and gently tug the wire to ensure that it is secure.

To use the push-type terminals on the connections panel sup- plied with the optional HTI88BB “back box” enclosure, depress the colored cap until the pass- through hole in the binding post is revealed. While holding the cap down, insert the bare end of the wire, or a banana plug, into the pass-through hole. Release the cap and tug gently on the wire to ensure that it is secure.

Since the HTI88 is a passive loudspeaker, only speaker-level connections are available. Depending on whether you are using a dedicated subwoofer
