PLACEMENT  
INSTALLATION  
The ERS Series in-wall speakers were designed to be easily  
installed. However, if you are unsure of your ability to properly  
install these loudspeakers, please contact your dealer or a  
qualified installer.  
Stereo  
Before deciding where to place your ERS Series speakers, survey  
your room and think about placement, keeping the following  
points in mind, and using Figure 1, on previous page, as a guide:  
• For best results, place the speakers 6'–8' apart.  
Tools Needed  
• When installing in the wall, position each speaker so that the  
tweeter is as close to ear level as practical.  
• Refer toHome Theaterbelow if you also plan to use the  
speakers in a home theater system.  
Pencil  
Phillips #2 screwdriver  
Utility knife  
Home Theater  
For front-channel use, place one speaker on the left and another  
on the right along either side of the television.  
Measuring tape  
A center channel speaker should go directly above or below the  
television and can be an in-wall or freestanding center channel.  
For left and right surround channels, place one speaker on the  
left and another on the right, to the side of or slightly behind the  
listening area.The surround speakers should be mounted at a  
height of between 4 feet and 7 feet.  
Carpenter’s level  
Awl  
In 6- or 7-channel configurations, place the rear channel(s)  
behind the listening position, as shown in Figure 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.  
Proper placement of the speakers is an important step  
in obtaining the most realistic soundstage possible.These  
recommendations are for the optimal placement of the loud-  
speakers. Use these placement recommendations as a guide.  
Slight variations will not diminish your listening pleasure.

SPEAKER CONNECTIONS  
Turn Off All Power  
Before completing the installation, you must connect your  
speakers to your system. First, turn off all audio-system power.  
Use high-quality speaker wire to make your connections. Use  
at least #16-gauge speaker wire with polarity coding. Heavier  
gauge wire is recommended for larger distances. Consult the  
chart below left or your dealer for recommendations.The side  
of the wire with a ridge or other coding is usually considered  
positive (+) polarity. Also, consult the owner’s manuals  
that were included with your amplifier or receiver to confirm  
connection procedures.  
Figure 4.  
Observe polarities when making speaker connections, as  
shown in Figure 4. 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.

OPERATION  
If you wish to preinstall a rough-in frame before the drywall  
is installed, you will need to purchase the correct rough-in-frame  
kit for your model:  
Surround Modes  
When using the system in a Dolby* Digital or DTS® home theater  
system, make sure all speakers are set toSmall. When using  
the ERS Series in a Dolby Pro Logic* home theater system,  
make sure the receiver’s center channel mode is set toNormal.”

Some Dolby Digital-equipped receivers/processors offer different  
setup options for each source or surround mode: e.g., CD-stereo,  
videotape, Dolby or Pro Logic. In each case, follow your  
equipment’s instructions to ensure that the subwoofer (if you have  
one) output is turned on and that the speakers are set toSmall”  
in each mode.

Painting the Speaker Frame and Grille  
ERS Series loudspeakers can be painted to match any décor.  
If you wish to change their color, the satin finish on the grille  
and frame will function as a primer coat. Before painting, install  
the paint shield (inner section of template in the assembly kit)  
securely into the recess in the baffle.This will protect the  
speaker components and baffle from paint residue. Use a  
high-quality spray paint, and apply a thin coat of color.  
Be certain the grille perforations remain free of paint.  
Filling them with paint will diminish the sound quality.  
Note: Gently remove the acoustical foam blanket from  
the grille before painting. Reattach the blanket after the  
paint has dried.
