INFINITY BETA SERIES The Infinity Beta ™Series of loudspeakers continues Infinitys longstanding commitment to accurate sound reproduction. Our patented Ceramic Metal Matrix Diaphragm (CMMD ™) drivers, precision dividing networks, and rigid, well-braced enclosures, along with our newly developed, patent- pending Constant Acoustical Impedance ™(CAI ™) waveguide, combine to deliver uncompromised performance in any stereo or multichannel home theater system. In addition, Beta Series speakers are magnetically shielded for safe placement adjacent to a television. UNPACKING THE SPEAKERS If you suspect damage from transit, report it immediately to your dealer. Keep the shipping carton and packing materials for future use. PLACEMENT Stereo Before deciding where to place your Beta speakers, survey your room and think about placement, keeping the following points in mind, using Figure 1 as a guide: - For best results, place the speakers 6'– 8' (1.5m– 2.5m) apart. - Position each speaker so that the tweeter is approximately at ear level. - Generally, bass output will increase as the speaker is moved closer to a wall or corner. - Refer to Home Theater below if you also plan to use the speakers for home theater reproduction. Figure 1. Experiment with speaker placement to obtain the best bass level and stereo imaging in your room. Home Theater For front-channel use, place one speaker on the left and another on the right, along either side of the television monitor. Since the speakers are magnetically shielded, you can place them near the TV without worrying about the field distorting the TV picture. For surround-channel use, place speakers on bookshelves or stands alongside the listening position. Final placement depends on room acoustics, availability of space and your listening preference (Figures 2 and 3). In 6- or 7-channel configurations, place the rear channel(s) behind the listening position, as shown in Figures 2 and 3. NOTE: An Infinity powered subwoofer will add impact and realism to both music and film soundtracks. Contact your Infinity dealer for recommenda- tions on subwoofer models for your application. Figure 2. This overhead view shows a typical home theater plan. Left/right rear channels are for a 7-channel system. Center rear channel is for a 6-channel system. Figure 3. This figure shows an alternate layout, which may be more suitable for some rooms. Left/right rear channels are for a 7-channel system. Center rear channel is for a 6-channel system.

3 BETA SPEAKER SYSTEMS INSTALLING FEET Beta 40 and Beta 50 These models feature four rubber feet, which enables them to be placed on a smooth-surfaced floor, such as tile or hardwood. Four metal spikes are supplied for use when the speaker is to be placed on a carpeted sur- face, to decouple the speaker from the floor and prevent unwanted damp- ing. To insert the spikes, gently lay the speaker on its side (not its front or back) on a soft, nonabrasive surface. Each spike screws into the threaded insert in the center of each rubber foot. Make sure all four spikes are screwed in completely for stability. NEVER drag the speaker to move it, as this will damage the spikes, the feet and/or the wood cabinet itself. Always lift the speaker and carry it to its new location. CAUTION: Floorstanding (tower) loudspeakers have a high center of gravity and may become unstable and tip over during earthquakes, or if rocked, tipped or improperly positioned. If this is a concern, these speakers should be anchored to the wall behind them, using the same procedures and hardware customary for anchoring bookcases and wall units. The customer is responsible for proper installation and proper selection of hardware.
