User manual INFINITY BETA ES250

[. . . ] If you are using the Beta ES250 as a rear speaker in a 6- or 7channel home theater system (Application 2), please follow the directions on page 3. The Beta ES250 also possesses the unique capacity to behave as two distinct loudspeakers from one enclosure. This allows you to use a single ES250 for both the left and right rear speakers in a 7-channel system. If you are using the Beta ES250 this way, please follow the instructions on page 3 (Application 3).

Placement (Application 1) When using the Beta ES250 for the surround channels in a 5-channel home theater system or for side channels in a 6or 7-channel home theater system, refer to Figures 1 and 2. The speakers should be placed perpendicular to or slightly behind the primary listening location, as shown.

BETA ES250 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. , +). Heavier-gauge wire should be used when more than 50 feet (15m) of speaker wire is required. The wire channels on the rear of the Beta ES250 will accommodate most types of 14- to 18-gauge wire. NOTE: If desired, consult your local Infinity dealer about speaker wire and connection options. 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 8. See the owner's guides that were included with your amplifier or receiver 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. Receiver or Amplifier (rear view) + ­ Applications 1 and 2 (one channel shown) ­ + Speaker (rear view) Figure 8.

Each speaker has (4) keyholes in the rear to allow either left- or right-side placement. Each speaker will require (2) 1-1/2" (38mm), #8 wood screws fastened to a wall stud. If a wall stud is unavailable, install an anchor appropriate for a 1-1/2" (38mm), #8 screw. [. . . ] If not, check all wiring connections or consult the authorized Infinity dealer from whom you purchased the system for more help. When the Beta ES250 speakers are used as part of a Dolby Digital or DTS® multichannel home theater system with a powered subwoofer, it is recommended that you set your receiver/processor speaker mode to "small" or "high-pass" for all channels connected to a Beta ES250. In addition, some receivers/processors allow you to adjust the high-pass frequency for the "small" or "high-pass" setting. If your receiver/processor has this capability, it is recommended that you set the highpass frequency to between 80Hz and 120Hz. [. . . ]
