To connect the Synthesis Four loudspeakers to the power amplifiers or receiver, use two-conductor insulated speaker
wire. We recommend #14 AWG wire as a minimum size. Your JBL dealer can recommend suitable cables.
Both the S4VC and S4HC utilize push-style friction binding posts that can accommodate up to #10 AWG stranded wire.
Since the S4Ai can be configured in three different ways, be sure to run the correct number and type of wires. Refer
to the S4Ai Wiring Guide on page 7.
PREPARING THE HOOKUP WIRE
1. First determine the distance between your amplifier and the most distant speaker in each group (fronts, surrounds,
back surrounds, subwoofers).
2.
Now make the hookup wires for all speakers in each group this length, even if one speaker is much closer
to your
amplifier than the other. This will help maintain proper signal balance.
3. Strip off 3/8" of insulation from both ends of each conductor.
4. T
wist each set of standard wires into a tightly bunched spiral.
5. Speakers and electronics terminals have corresponding (+) and (–) terminals. Most manufacturers of speakers and
electronics, including JBL, use red to denote the (+) terminal and black for the (–) terminal, although some electronics
manufacturers have adopted the new color-coding standard promulgated by the Consumer Electronics Association.
In that case, the positive terminal will be colored to correspond to the channel position, while the negative terminal
will be black.
It is important to connect all 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 poor imaging.
With the advent of multichannel surround sound systems, connecting all of the speakers in your system with the cor-
rect polarity remains equally important to preserve the proper ambience and directionality of the program material.
Now find a visual difference between the two conductors of each molded pair of speaker wires. 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 part of the outer insulation. It doesn’t matter which of the two
strands go to the (+) and (–) on the speakers and amplifiers, as long as all speakers are connected identically
. Push
down on the binding post, insert the wire into the hole, and release.
CONNECTING THE SPEAKERS TO THE REST OF YOUR SYSTEM
