Choose from the wiring options (single wire, bi-wire, bi-amp) before installation.COnneCTInG THe sPeaKers TO aMPLIFICaTIOnTo connect the Synthesis SCL-1 loudspeakers to power amplifier(s) or receiver, use two-conductor insulated speaker wire..WIRE LENGTH RECOMMENDED SIzEUp to 20 ft. 14-gaugeUp to 30 ft. 12-gaugueGreater than 30 ft. 10-gaugueThe SCL-1 spring-loaded binding posts can accommodate up to #10 AWG stranded wire.PREPARING THE HOOK-UP WIRE1. Determine the distance between your amplifier and the most distant speaker in each group (fronts, surrounds,rear surrounds).2. Make the hookup wires for all speakers in each group this same length, even if one speaker is much closer toyour amplifier than the farthest one to maintain proper channel balance. Remember to make extra wires for bi-amp or bi-wire usage should you opt for either method.3. Run wires through walls to the mounting positions.4. Strip off 3/8" of insulation from both ends of each conductor and twist each set of stranded wires into a tightlybunched spiral.5. Speakers and electronics terminals have corresponding positive (+) and negative (–) terminals. Mostmanufacturers of speakers and electronics, including JBL, Inc., use red to denote the (+) terminal and black forthe (–) terminal. Please confirm before connecting.It is important to connect all speakers identically: (+) on the speaker to (+) on the amplifier and (–) onthe speaker to (–) on the amplifier. wiring any one speaker “out of phase” (+ to - and - to +) to otherspeakers in the system results in thin sound, weak bass and poor imaging.Find a visual difference between the two conductors of each pair of speaker wires. Differentiating marks can be adifferent color wire (copper or silver); a strand of yarn in one conductor; thin, raised ribs on one part of the outerinsulation; 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 positive (+) to positive (+),negative (–) to negative (–) (Figure 8).Receiver/Amplifier(One Channel Shown)Side View of SCL-1 withSpeaker Connection PanelFigure 8
