INTRODUCTION The StageFront Home Theater Solutions loudspeakers are expressly designed for superior sonic quality in home theater applications. Each model employs advanced technology components that extract the subtle nuances in recorded music or the thunderous action sound in a movie. Models that end in “FX” are intended primarily for special effect placement. Models ending in “LCR” are designed for front channel left/center/right placement or wherever a monopole design is required.

INSTALLATION CONSIDERATIONS RECOMMENDED AMPLIFIER POWER For satisfactory performance, we recommend using a surround amplifier with a power rating of 20-150 watts for the Pro770FX. We recommend an amplifier power rating of to 20-200 watts for the Pro870FX. Most loudspeakers are not damaged by large amplifiers, but rather by small amplifiers. If your system is playing loud music, a small amplifier will run out of power very quickly and can create damaging “clipping” distortions.
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 rearor surround-loudspeaker array in a commercial theater.
Right Left Right Figure 1. ProFX loudspeakers are placed near back corner walls of a home theater room. Left Figure 2. ProFX loudspeakers are placed near back corner walls of a home theater room with an L-shaped sofa. ■ If your home theater system is capable of reproducing Dolby Surround EX® sound, consider using a second pair of StageFront FX loudspeakers (on the side walls) for an additional rear surround effect, as shown in Figure 3.
FINISHING THE INSTALLATION CONNECTING & INSTALLING THE LOUDSPEAKER 1. Please be sure to install the correct loudspeaker in the correct room position. Look on the rear label for “Right” or “Left” designation. Install in the appropriate position as viewed from the listening position facing the video display. optional placement Left Rear Left optional placement Right Figure 3.

4. Connect the other end of the loudspeaker wires to the home theater receiver (or amplifier) in the same way. 5. Turn on the home theater receiver and calibrate all loudspeakers in the system according to the receiver manufacturer’s instructions. Figure 5. Connecting loudspeaker wires to the ProFX terminals. CHECKING LOUDSPEAKER PHASE Speaker wire has two conductors.
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.
�� �� Figure 7. The Pro870FX includes Treble, Midrange, Bipole/Dipole and Diffuse Sound Level controls. OPERATION LISTENING AT HIGHER VOLUMES Achieving a reasonable volume of sound in a large room requires more amplifier power than it does in a small room. It is possible to turn the volume up so high that the amplifier runs out of power. This creates “clipping” distortion, which will make treble sound very harsh and unmusical.
