JBL Consumer Products INCLUDED One center channel loudspeaker 3 SPEAKER PLACEMENT Center Channel Speaker 0 ­ 0.6m (0 ­ 2 ft.) The center channel speaker should be placed slightly behind the front left and right speakers, and no more than two feet above or below the tweeters of the left and right speakers. It is often convenient to set the center speaker on top of the television set, as shown in the drawing. SPEAKER CONNECTIONS Connection Tips electronics, including JBL, use red to denote the (+) terminal and black for the (­) terminal. 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 a poor stereo image. With the advent of multichannel 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. Connect the JBL SCS 178 Center loudspeaker to the center channel output of your surround amplifier/receiver with correct polarity, plus-toplus and minus-to-minus. Separate and strip the ends of the speaker wire as shown. Speakers and electronics terminals have corresponding (+) and (­) terminals.
