INTRODUCTION
Product Description
The Russound RM691 High-Effi ciency Indoor/Outdoor
Loudspeaker is designed to provide high acoustic output
with low amplifi er power. This makes it perfectly suited
for use in outdoor areas with low- powered amplifi ed
keypads and volume controls.
Low-mass driver materials and state-of-the-art
engineering allow this speaker to produce higher sound
pressure levels than ordinary outdoor speakers without
sacrifi cing sound quality.
When ordinary speakers are used with low-powered
amplifi ed keypads, they have limited output, since they
are designed to handle higher power levels from other
types of amplifi ers. Because of its high effi ciency, the
RM691 plays more loudly than conventional speakers
when used with amplifi ed keypads.
The RM691 and its mounting bracket are easy to install.
Once the bracket is installed, the speaker slips into slots
Caution
The RM691 is for use only with amplifi ed keypads
and volume controls, or amplifi ers with a power
output of up to 20 watts per channel. Do not use
the RM691 with receivers or amplifi ers rated at
more than 20 watts per channel.
on the bracket so you don’t have to hold the speaker in
place while securing it. The bracket and speaker have
knurls for secure alignment to the desired angle.
Designed and built to withstand the rigors of outdoor
environments, the RM691 will provide years of troublefree service. It will work in a wide range of temperatures
and be unaffected by extremes of humidity. The only
consideration when installing the speaker outdoors is
to angle it slightly downward when mounting it in the
horizontal position to keep rain from entering the ports.
A corrosion-resistant aluminum grille couples with
the speaker’s rugged environmental design to assure
durability in any kind of weather. Adding to its versatility, the speaker can also be mounted indoors on walls,
posts, or joists—wherever it’s impractical to install inwall or in-ceiling speakers.

INSTALLATION
Painting the Speaker
The speaker mounting bracket, enclosure, end caps, and
grille can be painted. If you paint the speaker, be sure
not to get paint on the speaker drivers. Also be sure to
minimize paint buildup so as not to clog the grille holes.
1. Gently pull off the speaker grille, making sure not to
distort it.
2. Mask the speaker terminals and baffl e (the area on
the front of the enclosure that houses the drivers).
3. Paint the bracket, enclosure, end caps, and grille
separately. Spraying is ideal, but if you can’t spray the
paint, a roller with a short or medium nap will work
better than a brush. Apply one or two light coats.
4. While the paint is still wet, clear any clogged holes in
the grille with bursts of compressed air.
5. After the paint has thoroughly dried, remove the
masking. Gently press the grille back into place on
the speaker, using even pressure around the edge.
Prewiring
Run a separate 2-conductor stranded copper speaker
cable of at least 16 AWG (1.5 mm) from the amplifi ed
keypad or amplifi er to each speaker. Be sure to use
cable with the appropriate fi re resistance rating for the
application. Check the local building code for specifi c
requirements. Russound offers 2- and 4-conductor
speaker cables with a Class 3 fi re rating for in-wall
installation.
When running a speaker cable parallel to an AC power
cable, keep them at least 12 inches (30 cm) apart to
minimize electromagnetic interference. If the speaker
cables must cross AC wiring, cross them at right angles.
Leave about 2 feet (0.6 m) of cable at each end for connecting to the speakers and keypad or amplifi er. Label
the cables so you will know which cable connects to
each keypad or amplifi er output channel.
