INTRODUCTION

Introduction

Thank you for selecting the Russound Acclaim 7 Series In-wall LCR Speaker.

Like all Russound speakers, they combine acoustic technology with durability

and will provide years of musical enjoyment. The Acclaim line provides

solutions for background music, dedicated music listening and home theater.

The 7 Series combines premium acoustic materials, with our most advanced

drivers to deliver exceptional performance in every application. From

background music to spectacular surround sound, Acclaim speakers oer the

nest sound around.

Iso-Mount technology takes the Acclaim 7 Series beyond ordinary In-wall

speakers by reducing undesirable wall vibrations with a unique thermopolymer

isolation mounting gasket. Where typical In-wall speakers lack clarity due to

speaker-induced wall vibrations, Iso-Mount speakers oer dramatic sonic

improvement by letting the music come only from the speakers, not from the

wall. In addition, the innovative Twist & Lock mounting system incorporated in

Iso-Mount models provides exceptionally easy and secure installation.

Iso-Mount speakers have a molded-in IR receiver opening that allows

mounting an infrared remote receiver through the speaker bae. The polymer

plug is designed to pop out for screw-in installation of an IR receiver such as

the Russound SaphIR™ Eye without damaging the speaker bae.

In addition to Iso-Mount and Twist & Lock features, Russound Acclaim 7 Series

speakers feature high quality drivers, sophisticated crossover networks, and

advanced designs to ensure optimum reproduction.

The Treble frequency adjustment switch allows you to tailor the sound of

Acclaim speakers to better match the listening environment. The switch oers

three settings: +3 dB, -3 dB, or 0 dB. It is located on the front bae.

In a home theater, the LCR is intended for use in the front left, center, and

right positions adjacent to the video display. In stereo audio applications, a

pair of LCR speakers can be used for the left and right channels.

The benet is that one speaker model can be used for the three front channels

in a home theater. This provides identical voicing in all three positions, which

improves clarity and imaging.

Because the LCR is magnetically shielded, it can be used next to CRT televisions

without causing picture distortion. A separate subwoofer is recommended to

reproduce the lowest frequencies.

Although intended primarily for use as front speakers, the LCR models can

also be used as surround speakers in a multichannel audio system. As an

alternative, any Russound in-wall or in-ceiling speaker would work well for the

surround channels.

PREPARATION / WIRING INFO

Speaker Wire

The amount of wire needed varies with speaker placement. Label speaker

wires with left, right, and room location.

What kind to use: We recommend using Russound AW series speaker cable

or any reputable brand of 16 to 12 gauge multi-stranded wiring for amplier-

to-speaker connections.

Selecting the proper gauge: Wire is measured in gauges: the bigger the

number, the smaller the wire. The gauge of wire needed is determined by the

distance between your amplier/receiver and the speakers. The longer the

run, the heavier the gauge needed. Use the following chart as a guide:

Length Minimum Gauge

0' to 100' 16

50' to 150' 14

100' to 200' 12

If the conductors are not sheathed in colored jackets, utilize the conductors

consistently. The standard colors on the terminals are red Positive (+) and

black Negative (-). If the wire has transparent insulation, one conductor will be

copper-colored (+) and the other silver-colored (-). If the wire has an opaque

insulation, the conductors are dierentiated by a series of ribs or grooves, a

stripe, or dotted line on one conductor. Use and mark these as the Positive (+)

conductor.

Installation Tips

Wall and spacing requirements:

Any wallboard or paneling and 2" x 4" stud wall, or lath and plaster walls.•

A minimum depth of 4" (10 cm) measured from the outside face of the•

mounting surface, and at least 1 cubic foot of space behind the speaker for

optimal performance.

When installing the speakers, avoid:

Brick or concrete walls where the wallboard or paneling is attached to thin•

furring strips.

Walls where there are pipes, heating ducts and especially AC wiring in the•

general vicinity.

Incorporating optional IR receivers in the speakers will require additional

wire. Consult the selected IR receiver's manual for specic wire needs.

Speaker Wire Paths

Avoid running speaker wires close to house electrical wiring for any•

distance. If you have to run them parallel, leave two feet between the

wiring. Speaker wires should cross AC lines at a 90° angle.

The entire path between speakers and amplier should be clear and•

unobstructed. Conrm the placement for the wall port close to the

intended location of the amplier or receiver.

Label speaker wires at each end with left and right and the room location.•

Amplier Power

For home theater applications, we recommend at least 30 watts of amplier

power per LCR speaker.

PREPARATION / SPEAKER PLACEMENT

Determine the intended use of the speakers in the room. If they are going to

be your primary listening source in a room, you need to consider some other

factors to insure proper imaging. The term "stereo imaging" refers to a speaker

system’s ability to project music so that it sounds like the performers are in a

three-dimensional space between the speakers.

There are several factors to keep in mind before you begin actual installation.

In general, the best acoustic performance will result if both speakers face

a similar type of surface, are placed in similar positions on the same wall or

ceiling, and are mounted to the same type of material with equal cavity

volume.

Bass frequencies are emphasized when an In-wall speaker is placed close to

a corner. This tends to make male voices sound deeper and may muddy some

sounds such as sound track dialogue. Avoid placing just one speaker in a corner

and another on a long at wall.

Treble is emphasized when it bounces back from reective surfaces such

as large windows. Conversely, highs tend to be mued by soft surfaces

such as drapes, rugs, upholstered furniture, etc. The best situation is a mix of

absorptive and reective surfaces, which can be achieved by adding throw

rugs or insulated drapes to a reective room.

The tweeters should be placed at ear level of the intended user. In a horizontal

orientation, the speaker can be mounted with the tweeter at the top or bottom.

In a vertical orientation the speakers should be mounted with the tweeters

positioned to the outside and aimed toward the listener.

Speaker Placement and Use

Placement can make all the dierence in how your Russound speaker system

sounds. All rooms have dierent sound characteristics. Speaker location,

listening location, reective and absorbing surfaces all have a dramatic eect

on the sound you hear. There are at least four related considerations that factor

into the speaker layout:

•Theavailablelocations:unobstructedwallandceilingsurfaces

It may happen that the ideal or desired locations for the speakers may have to

be modied for feasibility.

PREPARATION / SPEAKER PLACEMENT

Home Theater

For home theater, wall or LCR speakers for the front three channels create the

illusion that the sound is coming from the screen, which makes the viewing

experience more involving and believable. In a multichannel audio system for

a home theater, one LCR should be installed horizontally above or below the

video display for the center channel, and two should be installed vertically to

the left and right of the display for the main front channels.

The center-channel speaker should be as close to ear level as possible; thus, if

the video display is mounted high, the speaker should be below it. If the display

is low, the speaker should be above it. The tweeter should then be angled up

or down as needed so that its axis points toward the ear level of the listeners.

The left and right speakers should be about 3' or 4' to either side of the screen.

Left and right speakers placed too close together or too far apart dissipate the

illusion of being "in the action" on the screen. For best results the tweeters

should be positioned on the outside, away from the video display.

Placement near corners

Placing a speaker near a corner of a room can cause sonic reections o the

side wall. This can result in a loss of clarity and poor imaging. Accordingly,

we do not recommend placing the LCR near a corner unless the side wall is

covered with sound-absorptive material.

Generally, the best acoustic performance will result if the left and right

speakers are placed in similar positions on the same type of wall surface.

Pre-wire or Pre-construction

Locate all obstructions (AC wiring, plumbing, duct work, and studs). Route

the speaker wire to the speaker location avoiding all obstacles.

Russound oers Speaker Rough-In Brackets that can be fastened to the

adjacent studs. Use a small level to make sure the bracket is straight. Once

the dry wall is installed, the opening is cut out. There are holes molded into

the bracket for speaker wire tie-o to keep the wire from being lost during

construction.

Make sure the speaker cutout (hole) doesn't extend further than ¼" (0.6 cm)

from the inside of the mounting bracket.

Retrot Installation

Locate existing pipes, duct work, and AC wiring before cutting any holes in

the walls.

Center the cardboard template between adjacent joists, avoiding all wiring,1.

pipes, duct work, and lightly mark the corners with a pencil. Then use a

keyhole/drywall saw or motorized spiral-cut tool to make the opening.

Score the outline of the template with a utility knife to prevent chipping.2.

If dealing with lath and plaster or thick paneling, drill 1" (2.5 cm) holes in

several places around the pencil outline. Use a ne-toothed keyhole saw

or hacksaw blade with slow strokes to saw through and remove the inner

surface.

PREPARATION FOR INSTALLATION

Painting the Speaker Frame and Grille

Russound Acclaim Speakers have a designer white nish that can be painted

with ordinary latex paint. Remove the speaker bae before painting.

Remove the speaker grilles. From the back of the speaker, push the clamp1.

(dog-ear) towards the grille to loosen it so you can pull it o. If the speaker

is already installed use a slightly bent paperclip to remove the grille.

Twist and remove the bae from the frame. Remove the scrim cloth from2.

the grille and set aside.

Paint the outer speaker frame and grille separately. Use the same coverage3.

on both the grille and frame. Russound recommends diluting the latex

paint with water 4:1 or 5:1 proportionally.

While the paint is still wet on the grille, and the grille is not in the frame, use4.

a gentle burst of compressed air against the outside surface to clear the

ne holes in the mesh.

After the paint has thoroughly dried, continue with the installation.5.

Additional Tips / Considerations

If possible, run speaker wires after AC wiring is in place to avoid induced•

hum caused by close parallel proximity of the two types of wire.

Secure speaker wires in place against a stud along vertical runs with•

insulated staples only. Do not pierce the wire insulation. Allow a bit of slack

for expansion of building materials.

Route horizontal wire runs through holes drilled in studs at roughly equal•

heights.

The speakers should not be installed until the wallboard is in place. In the•

meantime, leave several feet of wire coiled up and secured to the back

side of the mounting frame. Excess length can be removed during nal

assembly.

When installing the drywall, make sure the speaker cutout hole doesn’t•

extend farther than ¼" (0.6 cm) from the inside of the mounting frame.

Terminate the wires in an outlet box attached to a stud or retrot junction•

box at the exit location. Utilize an outlet plate which has connections for

speaker wire terminations. Russound dealers oer a full line of Russound

PlateMate™ connection systems.

After the drywall is secured and nished, install the speakers as described•

in this manual.

TESTS AND ADJUSTMENTS

Listening Test

It’s a good idea to test everything at this point.

Turn on your stereo system or music source. Make sure that the volume1.

control is turned down and that the balance control is set to center.

Gently turn up the volume. You should hear music coming out of your new2.

Russound Speakers! (If you don’t, refer to the troubleshooting guide.)

Now rotate the stereo’s balance control all the way to the left. Sound should3.

only come out of your left speaker. If it comes out of the right speaker, skip

to Step 5.

Rotate the balance control all the way to the right. Sound should only come4.

out of the right speaker.

If sound comes from the right speaker when the stereo’s balance control is5.

turned to the left, you’ll need to change the connections on the back of the

amplier/receiver. Note: Turn o the amplier. Swap the wires attached to

the left and right speaker terminals.

Tweeter Adjustment

The tweeters pivot and should be aimed toward the intended listener. Before

installing the grille, gently press on the outside of the tweeter ring as shown.

Adjusting the Frequency Response

Both models are equipped with a Treble frequency adjustment switch. Move

the switch to change the setting.

+3 dB: Increases the loudness of the selected frequency

-3 dB: Reduces the loudness of the selected frequency

0 dB: The frequency remains neutral (recommended start setting)

Grille Installation

After all adjustments and listening tests are made install the grille. Insert the

speaker grille by placing it over the speaker bae and aligning its edges in the

frame. Press gently into place, taking care not to scratch the frame nish or

bend the grille. In most installations, the grilles will t tightly without causing

vibration. If any audible vibration does occur, use the pre-cut lengths of special

damping/adhesive material.
