NTRODUCTION

InfinityTotal Solutions™

InfinityTotal Solutions continues Infinity’s longstanding

commitment to accurate sound reproduction.Our proprietary

Metal Matrix Diaphragm (MMD™) drivers,precision dividing

networks and rigid,well-braced enclosures combine to deliver

uncompromised performance in any stereo or multichannel home

theater system.In addition,these speakers,except for the

powered subwoofer,are magnetically shielded for safe

placement adjacent to a television.

Unpacking the Speaker

If you suspect damage from transit,report it immediately to your

dealer.Keep the shipping carton and packing materials for

future use.

LACEMENT

Stereo

Before deciding where to place your 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' 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“HomeTheater”below if you also plan to use

the speakers for home theater reproduction.

Figure 1.This overhead view shows typical positioning

in stereo applications.

Channel

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 without

worrying about the field distorting theTV 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 recommendations on subwoofer models for your application.

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.

WALL-MOUNTINGTHE SATELLITES

The SAT-750 satellites are designed to be mounted on the wall.

There is a wall bracket for each satellite speaker.Each speaker

bracket will require (2) 1-1/2,"#10 wood screws;each screw

should be fastened to a wall stud.If a wall stud is unavailable,

install an anchor appropriate for a 1-1/2,"#10 screw.

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.

Step 1.

Mark the positions on the wall where you would like to place the

mounting screws.

Step 2.

Place bracket against wall and fasten two 1-1/2,"#10 wood

screws through the bracket’s screw holes into the wall.If a wall

stud is not available,use an appropriate anchor.

Step 3.

Place the speaker on the wall by sliding the opening on the

bottom of the speaker over the bracket hook on the wall.Once

positioned properly,the speaker should slide down slightly and

become secure.

ONNECTIONS

Turn Off All Power

First,turn off all audio-system power.Use high-quality speaker

wire to make your connections.#18-Gauge speaker wire with

polarity coding is recommended.For longer distances,#16-gauge

or heavier wire is recommended.The side of the wire with a ridge

or other coding is usually considered positive polarity (i.e.,+).

Also,consult the owner’s manuals that were included with your

amplifier or receiver to confirm connection procedures.

Observe polarities when making speaker connections,as shown

in Figure 5.Connect each + terminal on the back of the

amplifier or receiver to the respective + (red) terminal on each

speaker.Connect the – (black) terminals in the same way.

Important!

Do not reverse polarities (i.e.,+ to – or – to +) when making

connections.Doing so will cause poor imaging and diminished

bass response.Be certain that positive and negative wire strands

are completely isolated to avoid short circuits that may damage

your equipment.

for one channel of a home theater system.

PERATION

Surround Modes

When using the system in a Dolby* Digital or DTS home theater

system,make sure all SAT-750 speakers are set to“Small”.

When using the SAT-750 in a Dolby Pro Logic* home theater

system,make sure the receiver’s center channel mode is set

to“Normal.”

Some Dolby Digital-equipped receivers/processors offer different

setup options for each source or surround mode,e.g.,CD-stereo,

videotape,Dolby,Pro Logic.In each case,follow your equipment’s

instructions to ensure that the subwoofer output is turned on and

that the speakers are set to“Small”in each mode.

AINTENANCE AND

ERVICE

The satellite enclosure may be cleaned using a soft cloth to

remove fingerprints or to wipe off dust.

All wiring connections should be inspected and cleaned or

remade periodically.The frequency of maintenance depends on

the metals involved in the connections,atmospheric conditions,

and other factors,but once per year is the minimum.

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 loud-

speaker.If the problem appears in the opposite speaker,the

cause is in another component or cable.In the event that

your SAT-750 ever needs service,contact your local Infinity

dealer or Infinity directly at 516-674-4INF (USA only) or

www.infinitysystems.com for a service center near you.
