INFINITY BETA SPEAKER SYSTEMS ™ Owner’s Guide Beta 10 Beta 20 Beta 40 Beta 50 Beta C250 Beta C360
INFINITY BETA SERIES Home Theater The Infinity Beta™ Series of loudspeakers continues Infinity’s 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, patentpending Constant Acoustical Impedance™ (CAI™) waveguide, combine to deliver uncompromised performance in any stereo or multichannel home theater system.
INSTALLING FEET Beta 40 and Beta 50 These models feature four rubber feet that enable 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.
WIRING THE SYSTEM Beta 40 and Beta 50 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.
BI-WIRING FINAL ADJUSTMENTS The outer connection panel and internal dividing network of the Beta 40 and Beta 50 are designed so that separate sets of speaker cables can be attached to the low-frequency transducer and midrange/highfrequency transducer portions of this dividing network.This is called bi-wiring. Bi-wiring can provide several sonic advantages and considerably more flexibility in power amplifier selection.
