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.
