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.
Tools Needed
PLACEMENT
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.
• When installing in the wall, position each speaker so that the
tweeter is as close to ear level as practical.
• Refer to“Home Theater”below if you also plan to use the
speakers in a home theater system.
HomeTheater
For front-channel use, place one speaker on the left and another
on the right along either side of the television.
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.
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.
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.
Wire Length Recommended Size
Up to 100 ft. 16-gauge
Greater than 100 ft. 12-gauge

NEW CONSTRUCTION
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:
Speaker Model Rough-In-Frame Kit
ERS 110II, ERS 110DT ERS 110RIF or IW6R RIF
ERS 210II ERS 210RIF
ERS 310 IW8R RIF
ERS HV250 IW55 RIF
Detailed installation instructions are supplied with the
rough-in kit.
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.
OPERATION
Surround Modes
When using the system in a Dolby* Digital or DTS®home theater
system, make sure all speakers are set to“Small.”When using
the ERS Series 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 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 to“Small”
in each mode.
