User manual INFINITY PRELUDE FORTY

[. . . ] Over time, the subtle advances add up and, when the latest model is compared to a loudspeaker that is 10 or 12 years old, the improvement is unmistakable. Every once in a while, a loudspeaker is developed that transcends this pattern ­ its performance so remarkable, its design so stunning, its technology so advanced, it can truly be described as revolutionary. The new Infinity Prelude® Forty loudspeaker system is an elegant case in point. The Infinity Prelude Forty 3-1/2-way design utilizes dual 8" CMMD® woofers, four patent-pending Maximum Radiating SurfaceTM (MRSTM) mid-bass/midrange drivers and an all-new 1" CMMD high-frequency driver. [. . . ] If the dispersion characteristics of the loudspeaker are different at various frequencies, the reflected sounds will be very different in quality both from each other and from the first (i. e. , direct) sound. The ears don't ignore these differences; they perceive them as coloration, or as sound quality that has been degraded. The Prelude Forty system has been carefully designed to maintain a directional pattern that is similar at every important angle, on and off axis. The positive result is that both direct and reflected sounds arriving at the listeners' ears have similar timbral signatures. An all-new, controlled-directivity waveguide ensures smooth high-frequency delivery across the entire listening area and increases high-frequency efficiency, lowering distortion and improving dynamic range. It is hoped that you have enjoyed this brief introduction to the technology of the Prelude Forty loudspeaker system. If you would like to further explore the technology and design of the Prelude Forty system, please ask your Infinity dealer for the CMMD and MRS white papers. The white papers can be downloaded from www. infinitysystems. com. INSTALLING GRILLES Top Grille 1.

UNPACKING THE PRODUCT Finish unpacking the speakers and check the contents. If you suspect damage from transit, report it immediately to your dealer and/or delivery service. While holding the grille at a 45-degree angle to the speaker, insert the two hook tabs into the two slots on the underside of the logo bar, as shown in the side view in Figure 3. Let the magnets draw the bottom of the grille against the driver trim area. Ensure the hook tabs are properly engaged in the slots of the logo bar to properly support the weight of the grille, as shown in the side view in Figure 4. INCLUDED: 1 x Prelude Forty loudspeaker 1 x Upper grille 1 x Lower grille 1 x Left woofer grille 1 x Right woofer grille 4 x Spikes 1 x Owner's manual 1 x USA warranty sheet Magnets Figure 3. Side Grilles Figure 4. ASSEMBLY INSTALLING SPIKED FEET Four metal spikes are supplied for use when using the speaker on a carpeted surface, to decouple the speaker from the floor and prevent unwanted damping. To insert the spikes, gently lay the speaker on its back on a soft, nonabrasive surface. NEVER drag the speaker to move it, as this will damage the spikes, the feet and/or the wood cabinet itself. Insert the six grille pins from the appropriate grille into the rubber cups in each woofer's trim panel, as shown with the right side grille in Figure 5. Figure 5. INFINITY PRELUDE FORTY 3 PLACEMENT The Infinity Prelude Forty loudspeaker is designed to offer excellent performance in any listening room. However, the following placement guidelines and suggestions will start you on your way to achieving optimum performance. It is suggested that you experiment with positioning the loudspeakers to determine their ideal placement in your particular listening room. Generally, the speakers should be placed at least 3' away from the side walls. [. . . ] Insert the speaker wire for the low frequencies into the bottom set of terminals and tighten. FINAL ADJUSTMENTS Check the speakers for playback, first by setting the system volume control to a minimum level, and then by turning on the power of your audio system. Play a favorite music or video segment and increase the system volume control to a comfortable level. NOTE: You should hear balanced audio reproduction across the entire frequency spectrum. If not, check all wiring connections or consult the authorized Infinity dealer from whom you purchased the system. [. . . ]
