PLACEMENT

Stereo

Before deciding where to place your Cascade speakers, survey your room

and think about placement, keeping the following points in mind and

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”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.

HomeTheater

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 magnetic 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.

Figure2.This overhead view shows a typical home theater plan.

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

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

moresuitable for some rooms. Left/right rear channels are for a

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

ASSEMBLY

It is strongly recommended that two people assemble the speakers

tominimize the possibility of damage or injury.

Installing Spiked Feet (Model Nine and Model Seven)

1. Open spike kit and locate the following items: feet (with spike/round

ends), four locking nuts, four nylon domes and one wrench.

2. Lay each stand on its side and locate the four threaded holes on the

bottom of the base.

3. For carpets,screw the round end of a foot into each hole and fully hand-

tighten a nut onto each one.For hard-surface floors, screw the spike end

into each hole instead and leave the rounded end exposed.

4. Carefully flip each base upright to sit on its feet.

5. If needed, adjust the feet so each speaker is level and then

tighten each

nut with the enclosed wrench.To protect hard surfaces (e.g.,wood floors),

slip a nylon dome onto each round end.

Note: Spiked feet must be fully threaded into holes provided in the base

to ensure stability.

This cross section shows how to install the spikes onto the bottom of a

Cascade Model Nine and Model Seven.

Model Nine and Model Seven

1. Remove floor

stand from carton.

2. Slide loud-

speaker onto

stand, making

sure the aligning

posts are lined up

with the receiver

terminal cup.

3. Insert #8 pan-

head screw into

rear of speaker to

secure to stand.

WALL-MOUNTING

NOTE: The customer is responsible for the correct selection and use of

mounting hardware (available through hardware stores) that will ensure

the proper and safe wall-mounting of the speakers.

at desired

location.

2. Securely fasten the

two cleats to the rear

of the speaker, using

the outermost holes,

using two included

1/4"-20 panhead

screws per cleat.

3. Carefully slide the

cleats on the rear

of the speakers

over the tabs

of the wall

Attaching the Grilles

The Cascade loudspeakers use a unique frameless grille. Each end of the

grille cloth contains a magnet. Simply curl the magnet assembly behind

the grille cloth, place one end of the grille just above the tweeter and

then gently pull the grille taut, attaching the other end of the grille just

below the woofer.

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.

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 4. Connect the –(black) terminals in a similar way.

See the owner’s guides that were included with your amplifier or 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.

Figure 5.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 6.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 Cascade

loudspeakers 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 7.

Figure 8.

Figure9.

FINAL ADJUSTMENTS

Check the speakers for playback, first by setting the system volume con-

trol to a minimum level, and then by turning on the power of 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.

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 Cascade Series enclosure has a finish that does not require any

routine maintenance.When needed, use a soft cloth to remove any finger-

prints or dust from the enclosure.

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

or grille.

If a problem occurs, make sure that all connections are properly made

and clean. If a problem exists in one loudspeaker, reverse the connection

wires to the left and right system. If the problem remains in the same

speaker, then the fault is with the loudspeaker. If the problem appears in

the opposite speaker, the cause is in another component or cable. In the

event that your subwoofer ever needs service, contact your local Infinity

dealer or distributor, or go to www.infinitysystems.com to locate a service

center near you.

IMPORTANT: Please attach your sales receipt to this manual and store it

in a safe place. In the event that your Infinity speaker requires warranty

service, you will need to provide your sales receipt.
