User manual INFINITY BETA 20

[. . . ] 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). [. . . ] Center rear channel is for a 6-channel system. 2 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 surface, to decouple the speaker from the floor and prevent unwanted damping. 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. BETA SPEAKER SYSTEMS 3 WIRING THE SYSTEM IMPORTANT: Make sure all equipment is turned off before making any connections. For speaker connections, use a high-quality 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. Beta 40 and Beta 50 Figure 6. This example shows how to connect bare wires to the terminals. Banana plugs may also be inserted directly into the rear of the connector. Figure 4. This figure shows how to connect bare wires to the terminals. Beta 10, Beta 20, Beta C250 and Beta C360 Figure 7. Wiring diagram shows polarity connections for one channel of a stereo or home theater system. Figure 5. [. . . ] If this happens, try angling the speakers slightly inward toward the listening position until the optimum effect is achieved. CARE OF YOUR SPEAKER SYSTEM FIGURE 8. Each Beta Series enclosure has a wood-grain-vinyl finish that does not require any routine maintenance. When needed, use a soft cloth to remove any fingerprints or dust from the enclosure or grille.
