General Description

With a majority of America’s workplaces having adopted an open office
plan, favoring a labyrinth of cubicles over traditional closed offices, con­versational privacy has become an increasingly sensitive issue. A prop­erly designed sound masking system can significantly increase speech
privacy and improve the overall work environment.
The new Atlas Sound M1000 masking speaker assembly is designed to
accurately reproduce the needed spectrum of masking sound into the
plenum space. The innovative 734 in
low frequency response. A specially designed 8" dual cone loudspeaker
is included in the package. A high efficiency 70.7V internal transformer
is coupled to an external selector switch for easy system tuning. For
more precise adjustments, an off switch and a wide selection of watt­age taps ranging from .25 watts to 4 watts are provided. Along with the
various wattage tap selections, the M1000-W comes with an 8
setting.
The exclusive Atlas Sound EZ hang brackets simplify installation. This
innovative suspension system utilizes two collapsible galvanized hang­ers configured to allow quick upward, downward, or horizontal firing
installation. The hangers are factory-installed on the unit and fold flat
for shipping. To meet most local code requirement, the M1000 includes
an innovative cover containing both knockouts and a strain relief. This
system will allow the use of rigid or flexible conduit (if required) and
easily accommodates “through” connections on the removable plate.
To fit continually shrinking construction budgets, the M1000 is very
aggressively priced. Contact your regional Atlas Sound representative for
details.
