FINISHING THE INSTALLATION
(CONTINUED)
ACOUSTIC FINE TUNING
Each StageFront Pro FX loudspeaker features a Diffuse Sound Level control located 
on the front, as shown in 
Figure 6. 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. 
SETTING THE BIPOLE/DIPOLE MODE
Each StageFront Pro FX loudspeaker features 
BIPOLE/DIPOLE switch located on the front, as 
shown in 
Figure 7. Set the BIPOLE/DIPOLE
switch on each StageFront FX loudspeaker 
according to the loudspeaker’s side or rear 
placement, as shown on pages 5 and 6. 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 4 for details)
INSTALLING THE GRILLES
If desired, at each loudspeaker, carefully fit each grille to its position on the cabinet. 
Starting with one corner, gently press the grille frame around the loudspeaker’s 
edge, pushing it in at each of the four recessed holes. When properly installed, the 
bottom and top of each grille will be nearly flush in appearance with the cabinet.
