Twist each set of thin wires into a tightly-bunched spiral. At this point you need to identify 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 does not make any difference which of the two strands of wire go to (+) and (­) on the speakers and amplifier, as long as both speakers are connected identically. If using wire ends, unscrew the colored nut on the terminal cup, insert the wire end into the hole in the metal post, then retighten the nut until the wire is 3 tightly secured. If using banana plugs, simply insert the plug directly into the holes on the top of the metal posts. For each channel, the red terminal on the loudspeaker should be connected to the red or (+) loudspeaker connection terminal on the receiver or amplifier, and the black to the black or (­) speaker conection terminal (see Fig. Connecting the loudspeakers in this manner ensures that they will be in phase; that is, work together rather than in opposition. Connecting the loudspeakers out of phase will not damage them, but will result in less bass and poor imaging. Left Speaker Red Blk. (+) (­) Right Speaker Red Blk.

However, some speakers may not be usable as a second pair if you want to play two sets at once. Before hooking up another set of speakers besides your GHE Series, check the following: 1. Your receiver or amplifier minimum load impedance. Impedance is always expressed in ohms and can be found in the owner's manual that came with your unit...
