INTRODUCTION

Infinity ERS™ Series

The ERS Series of in-wall/ceiling loudspeakers continues Infinity's longstanding commitment to accurate sound reproduction. Our patented Ceramic Metal Matrix Diaphragm (CMMD ^™ ) drivers and precision dividing networks deliver uncompromised performance in any stereo, multichannel home theater or whole-house music system.

Unpacking the Speakers

Carefully unpack the speakers. If you suspect damage from transit, report it immediately to your dealer and/or delivery service. Keep the shipping carton and packing materials for future use. All models include a mounting template and paint shield.

Before deciding where to best place your speakers, survey your room and study Figures 1–3.

Note: Figures 1, 2 and 3 show recommended speaker locations. You may also follow these general placement suggestions when installing the speakers in the ceiling.

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.

Home Theater

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 loudspeakers. Use these placement recommendations as a guide. Slight variations will not diminish your listening pleasure.

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.

Wire Length Recommended Size

Up to 100 ft. 16-gauge

Greater than 100 ft. 12-gauge

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.

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

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.
