Niles Audio OS6.5 manual Loudspeaker Phase

INSTALLATION

5.Connect one stripped wire end to the black and one to the red terminal. Pay attention to the markings on the wire. Each loudspeaker wire must be connected to the amplifier in the same way.

6.If required, attach the safety cable to the loudspeaker enclosure. See Safety First section for details.

7.Verify that the loudspeakers are in-phase as described in the Loudspeaker Phase section.

8.Angle the loudspeaker for the best sound possible.

9.Tighten the bracket knobs using only your hands. Use of any power tools may over-tighten the knob, and strip the threads of the insert.

10.Check that the entire installation is safe and secure.

Loudspeaker Phase

Loudspeaker wire has two conductors. One conductor is attached to the negative (-) terminals and one conductor is attached to the positive (+) terminals of both your loudspeaker and your amplifier. Usually, the wire is marked for your convenience. There are different ways to mark the wire; a stripe, a ribbed area you can only feel, different colors 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 to avoid mistakes. If you do, one loudspeaker will be playing out of “phase” with the other loudspeaker. An out-of- phase pair of loudspeakers work against each other and the sound of the two loudspeakers playing together will lack in bass and output. If you suspect the sound is not right and you cannot see any markings on the wire, try this simple test:

1.Point the loudspeakers at each other, rather than at you.

2.Play some music with the amplifier or radio set to Mono.

3.Stand so you are the same distance from each loudspeaker and listen to the richness of the bass and the loudness of the sound.

4.Turn off the amplifier and reverse the connections on one loudspeaker 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 loudspeakers are working together or “in-phase”.
