[. . . ] PRIMUS SPEAKER SYSTEMS Owner's Guide Primus 250 Primus 360 Primus C25 INFINITY PRIMUS SERIES TM 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. For rear-channel use, place Primus bookshelf speakers on bookshelves or stands ­ or Primus floorstanding speakers on the floor ­ alongside the listening position. [. . . ] · Generally, bass output will increase as the speaker is moved closer to a wall or corner. · Refer to the "Home Theater" section if you also plan to use the speakers for home theater reproduction.

For 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. The speakers have coded terminals that accept a variety of wire connectors. The most common connection is shown in Figure 4. 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 5. Connect the ­ (black) terminals in a similar way. See the owner's 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. FINAL ADJUSTMENTS Check the speakers for playback, first by setting the system volume control to a minimum level, and then by applying power to 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 for more help. [. . . ] When needed, use a soft cloth to remove any fingerprints or dust. NOTE: Do not use any cleaning products or polishes on the cabinet or grille. Figure 4.
