SETTING THE BIPOLE/DIPOLE MODE
Each StageFront FX loudspeaker features a BIPOLE/DIPOLE switch located on the
front, as shown in Figure 8. Set the BIPOLE/DIPOLE switch on each StageFront
FX loudspeaker according to the loudspeaker’s side or rear placement, as shown in
Figure 8. Here are some tips on usage:
Use the DIPOLE setting on rear loudspeakers when listening to movies and classical
music. The sound will be less focused as it is reflected along the room’s boundaries.
This is the best choice, since most films are mixed using non-localized surround
effects, and classical music is usually recorded in a favorable acoustic environment.
Use the BIPOLE setting on rear loudspeakers when listening to discrete multi-
channel recordings that equally emphasize front and surround sounds.
For multiple sets of StageFront FX loudspeakers, use the DIPOLE setting on the side
loudspeakers (aimed at the listening position) for a more DIFFUSE surround effect.
For the rear loudspeakers, use the BIPOLE setting to focus the sound.
With the 1/8” (3.5 mm) trigger input for Bipole/Dipole mode switching, an IR macro
can be used to control the loudspeaker mode. You can program this as part of your
source selection. This is an easy way to have Dipole envelopment for Movie sources
and Bipole performance for Music sources. (refer to page 5 for details)
ACOUSTIC FINE TUNING
Each StageFront In-Wall FX loudspeaker features a Diffuse Sound Level control
located on the front for acoustic fine-tuning after installation, as shown in
Figure 8. Adjust this control as follows:
The Diffuse Sound Level control adjusts the level between the side-firing (diffuse)
and front-firing drivers. Increase the level with this control for more ambiance. A
decrease with this control will yield a more direct sound.
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 flush
in appearance with the frame.
