INFINITY PRIMUS -„¢ SERIES The Primus series of loudspeakers continues Infinitys longstanding commitment to accurate sound reproduction. Our proprietary Metal Matrix Diaphragm (MMD -„¢) drivers, precision dividing networks, and rigid, well-braced enclosures combine to deliver uncompromised performance in any stereo or multichannel home theater system. In addition, Primus 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 Primus 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' 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 without worrying about the field distorting the TV picture. Forrear-channel use, place Primus bookshelf 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). The center channel speaker should be placed on top of or directly below the television and aimed toward the listening area. 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 4. Step 1. Mark the positions on the wall where you would like to place the mounting screws. Step 2. Fasten two 1-1/2," #10 wood screws to the wall using the markings placed in Step 1 as your guide. Leave an 11/16" space between the wall and screwhead. If a wall stud is not available, use an appropriate anchor. Step 3. Place the speaker on the wall by aligning the keyholes on the back of th\ e speaker to the screwheads on the wall. Once positioned properly, the speaker should slide down slightly and become secure. T he Primus 140 also allows the use of third-party wall brackets using the 1/4"-20 threaded insert located beneath the keyhole mount. Consult the wall-bracket manufacturer for selection of proper bracket. -“ + Keyho le mounts 1/4"-20 Threaded insert (Primus 140 only) F igure 6. Wiring diagram shows polarity connections for one channel of a stereo or home theater system. W IRING THE SYSTEM IMPORTANT: Make sure all equipment is turned off before making any connections. F or speaker connections, use a minimum #16-gauge speaker wire with polarity coding. The side of the wire with a ridge or other coding is usually considered positive polarity (i.e., +). NOTE: If desired, consult your local Infinity dealer about speaker wire and connection options. T he speakers have coded terminals that accept a variety of wire connec- tors. The most common connection is shown in Figure 5. To ensure proper polarity, connect each +terminal on the back of the amplifier or receiver to the respective +(red) terminal on each speaker, as shown in Figure 6. Connect the -“(black) terminals in a similar way. See the owners guides that were included with your amplifier, receiver and television to confirm connection procedures. IMPORTANT: Do not reverse polarities (i.e., + to -“ or -“ to +) when making connections. Doing so will cause poor imaging and diminished bass response . W ALL -M OUNTING THE PRIMUS 1 40 AND PRIMUS 15 0 T he Primus 140 and Primus 150 are designed to mount directly to a wall. Each satellite speaker has two keyholes on the back. Each speaker will require (2) 1-1/2," #10 wood screws fastened to a wall stud. If a wall stud is unavailable, install an anchor appropriate for a 1-1/2," #10 screw. NOTE: T he customer is responsible for the correct selection and use of mounting hardware (available through hardware stores) that will ensure the proper and safe wall-mounting of the speakers.
