Introduction / Preparation
Speaker Wire Paths
Thank you for selecting the Russound Universal In-ceiling Speakers. Like all
Russound speakers, they combine acoustic technology with durability and will
provide years of musical enjoyment.
Russound Universal speakers should only be installed by authorized
Speaker Wire
The amount of wire needed varies with speaker placement. Label speaker
wires with left and right and room location, taking the guesswork out of which
wires go where when installing speakers later.
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 amplifier-tospeaker 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 amplifier/receiver and the in-wall speakers. The longer
the run, the heavier the gauge needed. Use the following chart as a guide:
0 to 100 ft.
50 to 150 ft.
100 to 200 ft.
Minimum Gauge
In general, pay particular attention to the following areas:
• Avoid running speaker wires close to house electrical wiring for any
distance. If you have to run them parallel, make sure to space the speaker
wires at least two feet from the AC line. It is permissible for speaker wires to
cross paths with AC lines or go through the same hole together with house
wiring if they separate before and after.
• Make sure that the entire path between speakers and amplifier is clear and
not obstructed by a floor or ceiling joist or masonry wall which you won’t
be able to drill through.
• Remember that the other end of the wires has to come out somewhere
to connect with the amplifier. Confirm ahead of time that you can drill an
outlet hole easily and in an unobtrusive spot.
Cutting Holes for the Speakers
1. Determine the location of the joists so that the speaker can be approximately
centered between them.
2. Locate the joists, electrical cables, water pipes, and heating ducts. Center a
cardboard mounting template between adjacent joists, avoiding all wiring,
pipes, duct work, and draw an outline with a pencil.
3. Score the outline of the template with a utility knife to prevent chipping.
Then use a keyhole/drywall saw or motorized spiral-cut tool to make the
opening. If dealing with lath and plaster or thick paneling, drill 1-inch holes
several places around the pencil outline. Use a fine-toothed keyhole saw
or hacksaw blade with VERY slow strokes to saw through and remove the
inner surface.
When installing the speakers, avoid:
• T-bar “drop ceilings” with very thin fiberboard panels which can buzz
and vibrate. If needed, reinforce the drop-in panel with wood or particle
• Ceilings where there are pipes, heating ducts and ESPECIALLY AC wiring in
the general vicinity. This applies for ceiling fans, overhead lighting, etc.

Speaker Connections
Hooking Up the Speakers
At the Speaker End
Discriminate between the two conductors of the speaker wire. If the wire has
transparent insulation, one conductor will be copper-colored and the other
silver-colored. Generally, professionals denote the copper one as POSITIVE (+)
and the silver one as NEGATIVE (-).
1. Cut off excess wire, leaving about 2 feet extending through the speaker cutout hole.
If the wire has an opaque insulation, there are still differentiating markings.
Examine the wire closely and look for a series of ribs or grooves on one conduct,
or a painted stripe or dotted line. Denote any of these as the POSITIVE (+)
conductor for similar connections on both ends. IMPORTANT: Label the wires
left and right to eliminate future confusion.
3. Using a wire stripper, diagonal pliers or a knife, remove 1/2 inch of insulation
from each conductor.

negative (-)(solid) speaker wire conductors
2. Pull the conductors apart so they’re separated for the first two inches from
their ends.
4. Twist the tiny strands in each conductor into tight spirals.
5. Attach the speaker wires to the red and black speaker terminals. Connect the
POSITIVE (+) conductor to the RED terminal and the NEGATIVE (-) conductor
to the BLACK terminal. Press down on the protruding levers while inserting
the wire. Make sure that no stray strands of wire have gotten detached and
are touching the other main wire.
At the Amplifier End
1. Cut off excess wire, leaving enough to comfortably reach from the hole
in the wall to your stereo system. If there’s a possibility that you’re going
to move the amplifier to another part of the room, consider leaving some
excess wire coiled up.
2. Pull the conductors on both speaker wires apart so they’re separated for the
last two inches.

3. Using wire strippers, diagonal pliers or a knife, remove 1/2 inch of insulation
from each conductor.
4. Twist the tiny strands in each conductor into tight spirals.
5. Attach the speaker wires to the red and black speaker terminals on the
amplifier or receiver. Connect the POSITIVE (+) conductor to the RED
terminal and the NEGATIVE (-) conductor to the BLACK terminal of the
receiver/amplifier. Make sure that no stray strands of wire have gotten
detached and are touching the other main wire.
6. Repeat Steps 1 through 5 for the other speaker.

Final Assembly & Troubleshooting
Final Assembly
Troubleshooting Guide
1. Remove the perforated grilles from both Russound speakers. Use the clamp
(dog-ear) to push the grille out from the back side.
2. Center the speaker in the cut-out hole and tighten the screws until the
clamps are drawn up snugly from behind, clamping the speaker in place.
Try to tighten each screw equally but do not over tighten.
3. Insert the Russound speaker grille by gently pressing it into place. The grilles
will fit tightly without causing vibration.
Before returning your Russound speakers for service, try these simple remedies
No sound from either speaker:
• Incorrect source selected on receiver or preamplifier.
• Mute button pressed on receiver.
• Wrong speaker output selected; many receivers have an “A” and “B” speaker
switch. Make sure it is in the correct position.
• In-Wall Volume control not turned up or wired incorrectly.
• If using a speaker selector, room/station not turned on or improperly
No sound from one speaker:
• Unsecured connection at either the speaker or amplifier - double-check all
• Balance control turned all the way left or right - return it to center.
• Bad connecting cable between sound source and amplifier - try a new
• Defective speaker - contact your Russound dealer or call Russound Tech
Support at 603.659.5170.
• Any other problems not listed, discuss with your dealer or call Russound.
