Connection Tips					Separate and strip the
					ends of the speaker wire
					as shown. Speakers and
					electronics terminals have
					corresponding (+) and (–)
					terminals. Most manu-
					facturers of speakers and
					electronics, including JBL,
					use red to denote the (+)
					terminal and black for the
					(–) terminal. To use the
					spring-type terminals, simply
					press the colored terminal,
					insert the bare end of the
					wire into the hole, and
					release. The clip inside the
					terminal grips the wire. Tug
					the wire gently to make sure
					that it has been inserted
					properly.

The (+) lead of the speaker wire is usually indicated by a stripe, ridges in the wire insulation, or gold-colored strands inside clear wire insulation. 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 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.
