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 trouble-
free 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 versatil-
ity, the speaker can also be mounted indoors on walls,
posts, or joists—wherever it’s impractical to install in-
wall or in-ceiling speakers.
