Of course, there are some wires that appear completely identical. So be careful, or you might make a connection mistake. If you do, one loudspeaker will be playing “out-of-phase” with the other loudspeaker. A pair of out-of-phase loudspeakers works against each other, and the sound of the two playing together will be lacking in bass and sound “phasey.” If you suspect the sound is not right, and you cannot see any markings on the wire, try this simple test:

1.Stand halfway between the loudspeakers.

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 volume control setting. When the sound has a richer bass and is slightly louder, the loudspeakers are working together or “in-phase.”

ACOUSTIC FINE TUNING

Each StageFront 70 Series In-Wall LCR loudspeaker features TREBLE and MIDRANGE variable controls located on the front for acoustic fi ne-tuning after installation, as shown in Figure 7. Adjust these controls as follows:

■If you desire more dialog presence, increase the amount of midrange frequencies produced by turning the MIDRANGE control clockwise.

■If a StageFront LCR model is placed in a room with highly reflective surfaces like glass or tile, you may wish to decrease the amount of high frequencies produced by turning the TREBLE control counter-clockwise.

INSTALLING THE GRILLE

Starting at one corner, carefully align the magnetic grille into the frame and slowly allow the magnets to attach. Work around the grille edge, ensuring that the grille stays within the frame. When properly installed, the edges of the grille will be fl ush in appearance with the frame.
