Speaker Phase
Speaker wire has two conductors. One conductor is attached to the negative (-) terminals and one conductor is attached to the positive (+) terminals of both your speaker and your amplifier. Usually, the wire is marked for your convenience. There are different ways wires are marked: a stripe on one wire, a ribbed area of one conductor you can only feel, different col- ors of metal wire on each conductor, or there might be a fabric strand or string wound into one of the conductors. Of course, there are some wires which appear completely identical. Be careful, or you might make a mistake.
If you make a mistake, one speaker will be playing “out-of-phase” with the other speaker. An out-of-phase pair of speakers work against each other and the sound of the two speakers playing together will be lacking in bass and be “phasey” sounding. If you suspect the sound is not right and you cannot see any markings on the wire, try this simple test:
1.Stand half way between the two speakers.
2.Play some music with the amplifier or radio set to Mono.
3.Listen to the richness of the bass and the loudness of the sound.
4.Turn off the amplifier and reverse the connections on one amplifier channel only.
5.Repeat the listening test with the same setting of the volume control. When the sound has a richer bass and is slightly louder the speakers are working together or “in-phase”.
Setting the High-Pass Filter
When the “High Pass” filter is in the ON position, all of the bass energy will be pro- duced via the PSW8. When the switch is in the OFF position, both the satellite speakers and the PSW8 will reproduce the bass signal. Typically, satellites with woofers that are 5-1/4” or smaller will sound best with the filter on. Listen to a loud and well recorded bass passage to evaluate (See Figure 23).
