INFINITY BETA SERIES

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, patent-

pending Constant Acoustical Impedance™(CAI™) waveguide, combine to

deliver uncompromised performance in any stereo or multichannel home

theater system. In addition, Beta 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 Beta 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' (1.5m–2.5m) 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 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).

In 6- or 7-channel configurations, place the rear channel(s) behind the

listening position, as shown in Figures 2 and 3.

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 2.This overhead view shows a typical home theater plan.

Left/right rear channels are for a 7-channel system. Center

rear channel is for a 6-channel system.

Figure 3.This figure shows an alternate layout, which may be

more suitable for some rooms. Left/right rear channels are for a

7-channel system. Center rear channel is for a 6-channel system.

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 sur-

face, to decouple the speaker from the floor and prevent unwanted damp-

ing.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.

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 connec-

tors.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.

Figure 4.This figure shows how to connect bare wires to the terminals.

channel of a stereo or home theater system.

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 7. Wiring diagram shows polarity connections for one channel

of a stereo or home theater system.

BI-WIRING

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/high-

frequency 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.

FIGURE 8.

FIGURE 10.

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.

The amount of bass you hear and the stereo-image quality will be affected

by a number of different factors, including the room’s size and shape,

the construction materials used to build the room, the listener’s position

relative to the speakers, and the position of the speakers in the room.

Listen to a variety of music selections and note the bass level. If there is

too much bass, move the speakers away from nearby walls. Conversely, if

you place the speakers closer to the walls, there will be more bass output.

Nearby reflecting surfaces can adversely affect stereo-imaging quality. If

this happens, try angling the speakers slightly inward toward the listening

position until the optimum effect is achieved.

CARE OF YOUR SPEAKER SYSTEM

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.

NOTE: Do not use any cleaning products or polishes on the cabinet

or grille.
