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:

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.
