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.

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.

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.

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.

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.

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.
