LOUDSPEAKER PLACEMENT

NOTE: STAGEFRONT FX LOUDSPEAKERS ARE DESIGNED FOR USE IN EFFECT CHANNEL APPLICATIONS. FOR FRONT LEFT, CENTER OR RIGHT-CHANNEL NEEDS, WE RECOMMEND USING STAGEFRONT LCR LOUDSPEAKERS.

PLACING THE STAGEFRONT FX AS THE SIDE LEFT AND RIGHT LOUDSPEAKERS

In home theater, the goal is to reproduce the experience of a great movie theater in your home. The biggest difference between the two venues is the use of a rear- or surround-loudspeaker array in a commercial theater. Here, it is not uncommon to see 20 or 30 loudspeakers placed around theater walls. This huge array of loudspeakers assures the audience will feel completely surrounded by the ambient soundtrack of the movie.

Filmmakers carefully use the “surround” soundtrack to envelope viewers in the sound environment on screen. They will place background music, rain sounds, traffic noise, etc. on the “surround” soundtrack to create desired effects. However, in a home with a single pair of front loudspeakers, this surround effect will be lost, and jungle sounds may actually sound like they are emanating “from the middle of your head,” just like headphones!

Each StageFront FX loudspeaker is equipped with a BIPOLE/DIPOLE front switch as well as a 12-volt trigger jack on the rear of the enclosure. This jack will switch the StageFront FX loudspeaker from the front switch setting to its opposite position (such as from a setting of Dipole to Bipole) for as long as voltage is applied to this connection. Tip is positive. Use a source that will supply 12 volts DC 200 mA minimum for this trigger. These controls optimize the surround effects for either side or rear placement as well as various surround modes. (see SETTING THE BIPOLE/DIPOLE MODE on page 8). Here are some recommended loudspeaker placement tips:

■Place the surround loudspeakers on a rear wall directly behind the listening position. If possible, try placing the loudspeakers nearer to the corners, as shown in Figure 1 and 2. Set each BIPOLE/DIPOLE switch to DIPOLE for reflected sound. Moreover, the adjoining walls will act as powerful reflectors to create even more reflections.

■If you place the surround loudspeakers farther away from the listener, the surround sound will dissipate, requiring even more power from the surround-sound channels. If your sound system uses a small (less than 50 watts per channel) surround amplifier for the rear loudspeakers, be sure to place the loudspeakers within 5 to 8 feet of the listening location.

■If you are using a larger (more than 50 watts per channel) surround amplifier, you can mount the loudspeakers 10 to 15 feet away from the listening location and still achieve reasonably high volume levels. In large or unusually shaped rooms, this might be the only way to achieve a good effect.
