User manual JBL HT1D

[. . . ] They are divided into front channel speakers (HT1F: LeftCenter-Right), subwoofers (HT1S), and dipolar surround speakers (HT1D). FRONTS (Left-Center-Right) The Left and Right front channel speakers should be located on either side of the T. V. Closer to the screen gives you more localization while farther (two to three feet from the screen on each side) will give you a wider sound field. [. . . ] CONNECTIONS To connect the loudspeaker systems to the receiver or amplifier, use two-conductor insulated wire. Your JBL dealer can recommend suitable cables, or you can buy wire at most hardware stores. High-quality connectors and cable offer consistent performance that won't deteriorate over time. If your speakers are more than 30 feet (10 m) from your receiver or amplifier, use larger diameter wire. Make connections at the terminals located on the back of the loudspeaker system. The terminals accept bare wire or dual banana plugs, either of which will provide easy, secure connections. 5 NOTE: Do not attempt to install any type of mounting brackets onto your speakers. First determine the distance between your amplifier and the most distant speaker in each group (fronts, surrounds, subwoofers). Now make the hookup wires for all speakers in each group (fronts, surrounds, subwoofers) this length, even if one HT Series loudspeaker is much closer to your amplifier than the other. Now find a visual difference between the two conductors of each molded pair of speaker wire. Differentiating marks can be a different color wire (copper or "silver"); a strand of yarn in one conductor; thin, raised ribs on one part of the outer insulation; or a printed "+" marking on one of the insulators. It doesn't matter which of the two strands of wire go to (+) and (-) on the speakers and amplifier, as long as all speakers are connected identically. Unscrew the binding post, insert the wire into the hole, then re-tighten the binding post. If using banana plug type wire connectors just insert them directly into the posts making sure the lug on the negative (-) side of the banana plug is placed into the black binding post. For each channel, connect the red terminal on the loudspeaker to the red or (+) loudspeaker connection 6 terminal on the amplifier and the black to the black or (-). Connecting the loudspeakers this way ensures that they will be in phase; that is, work together, not in opposition. Connecting the loudspeakers out of phase will not damage them, but will result in less bass and poor imaging. HOOK UP TO AMPLIFIER Connect your HT speakers to your amplifier following the Red (+) to Red and Black (-) to Black convention as outlined in the last section. [. . . ] Make sure you follow the Red (+) to Red and Black (-) to Black convention. DO NOT remove the strap connecting the right-hand set of binding posts. Your single subwoofer connection is complete. NOTE: THX®-LICENSE IS DEPENDENT ON THE USE OF TWO SUBWOOFERS. [. . . ]
